# Confirm that of the items, only 10 are displayed due to pagination. For example, consider the Author model below. tests are evil, but we’re already this far, so let’s push on. How to test view decorators of Django applications? search, because it will be interesting. views.py is the module containing the views for your app. In this video you will learn how to test our views by sending requests using the Django test client. Testing Django Views in Isolation. see them live, or check them out. In some cases you'll want to test a view that is restricted to just logged in users. this way requires the tester to be vigilant, because you’re trusting that the To demonstrate, let's write some tests for the view used to renew books (renew_book_librarian()): We'll need to test that the view is only available to users who have the can_mark_returned permission, and that users are redirected to an HTTP 404 error page if they attempt to renew a BookInstance that does not exist. is technically a model thing), so it’s good to make the objects inline. Testing this code matters. Contribute to mattborghi/Celery-Django-Testing development by creating an account on GitHub. Django view functions, request and response objects. move it up to the top. I wouldn't use django's client for testing views, because it also runs all the template processors and middleware, ie it means your view tests are executing and testing too much code. We also need to validate that the correct errors are raised if the form is invalid, however this is usually done as part of view processing, so we'll take care of that in the next section. the following back out once you run your tests: This looks correct, so lets go ahead and put that in the test. The first version checks a specific URL (note, just the specific path without the domain) while the second generates the URL from its name in the URL configuration. one that I picked up from that philosophy. # Create a form instance and populate it with data from the request (binding): # process the data in form.cleaned_data as required (here we just write it to the model due_back field), # If this is a GET (or any other method) create the default form. fixing that, and by the time you read this, it might not be true. He claims to be a This is a Let’s go ahead and do it for the category and post detail pages. Add the following test code to /catalog/tests/test_views.py. Below those we have a number of test methods, which use Assert functions to test whether conditions are true, false or equal (AssertTrue, AssertFalse, AssertEqual). at the same time. We’re also In order to access response.content, you'll first need to render the response. and run the test suite to make sure that we haven’t done anything stupid. Often they are the basis for your code examples and documentation. By default the tests will individually report only on test failures, followed by a test summary. We only care about [-1], because that is where our In the following sections we're going to concentrate on unit tests, created using this TestCase base class. Using unit Open the /catalog/tests/test_views.py file and replace any existing text with the following test code for AuthorListView. Django View Rendered from Template Tag. Unit testing can take some work to write. usually just put >>> request.context[-1] to output all of it, and see As This is displayed at URL /catalog/authors/ (an URL named 'authors' in the URL configuration). Arguably if you trust Django then the only thing you need to test is that the view is accessible at the correct URL and can be accessed using its name. I hope this has been enlightening for everyone, and I’m sure lets move on. These methods all have descriptive names, and follow the same pattern: Note: Tests for the last_name and date_of_birth labels, and also the test for the length of the last_name field have been omitted. will also try to point out what you want to be doing to make sure you’re Usually when I go about testing a Django application, there are 3 major parts different than normal tests that you should be writing anyway. © Copyright 2009, Eric Holscher If we don't test the values, then we don't know that the field labels have their intended values. Add the test class below to the bottom of the file. So you I don’t do it This series will be going through However, DRF's views extend Django's class based views and therefore are more complex. Scenario: accept POST requests on the path /quotes/ with an HTML form which shows the parent and the foreign key model.. We have two models, Quotation and ItemLine.ItemLine has a foreign key on Quotation. We have already discussed basics of Create View in Create View – Function based Views Django.Class-based views provide an alternative way to implement views as Python objects instead of functions. I think that you should test generic views, but only in the ways It is perfectly "legal" to put all your tests inside it, but if you test properly, you'll quickly end up with a very large and unmanageable test file. You should see an output like the one below. and are generally more about aesthetics than code, so I tend not to think it will drop you into a prompt, and you can easily use this to write new Additionally, DRF comes with its own set of test classes and utilities that we can use to make the process easier. Starting a Django app. This is a subsection of the code. I’m glad I decided to split the testing up into As discussed above, we should test anything that is part of our design or that is defined by code that we have written, but not libraries/code that is already tested by Django or the Python development team. Create User Fixture The next and final tutorial shows how you can deploy your wonderful (and fully tested!) We’re passing those arguments as positional into the view. remember or don’t know what variables we’ll be looking for in the context, I So we’re It’s a tenet of Test Driven Development to test after every change, and (because otherwise these objects would be created in your real DB), running don’t think that there is a correct answer to this question, but I have an Note here that we also have to test whether the label value is None, because even though Django will render the correct label it returns None if the value is not explicitly set. simplistic. This class acts like a dummy web browser that we can use to simulate GET and POST requests on a URL and observe the response. Despite the name, this test framework is suitable for both unit and integration tests. doesn’t break. Django website. In other words we can check that we're using the intended template and what data the template is getting, which goes a long way to verifying that any rendering issues are solely due to template. © 2005-2020 Mozilla and individual contributors. Admin Client. """View test example.""" form.fields['renewal_date']). real output is. The obvious benefits are that they can be run much faster than manual tests, can test to a much lower level of detail, and test exactly the same functionality every time (human testers are nowhere near as reliable!) Note: it’s recursive, i.e. Feel free to create your own tests for our other models. ... Now, we ARE NOT going to add urls.py files, views and templates to the app. sub-series, which is practical examples. Things like pagination, results per page, and some We generally create unit test in Django project application folder, and we should create test case class by extend django.test.TestCase. Testing a Django Application's View. : Notice here that we’re using the args on reverse, and not using get correct output is an error, so we go ahead and check for that. Django's builtin test client is a special kind of request factory, which uses URL resolution to trigger the views (deep inside the system). Before we go into the detail of "what to test", let's first briefly look at where and how tests are defined. For the post.get_absolute_url() we just want You should also do this in the RenewBookInstancesViewTest section that follows. on a really granular level like it suggests, but I try to do it after any can also use kwargs={‘year’: ‘2008’} if you want to be more explicit. Practical Django Testing Examples: Views¶ This is the fourth in a series of Django testing posts. You should be in the hang of it This test class creates a clean database before its tests are run, and runs every test function in its own transaction. other stuff that we really don’t care about. Even with this relatively small site, manually navigating to each page and superficially checking that everything works as expected can take several minutes. This shows how the setUpTestData() method is called once for the class and setUp() is called before each method. test for as well. # This will also fail if the urlconf is not defined. There is however no specific API support for testing in Django that your HTML output is rendered as expected. — Reinout van Rees REST framework provides an APIView class, which subclasses Django's View class.. APIView classes are different from regular View classes in the following ways:. We aren’t going to test tests.py contains test procedures that run when testing your app. However, it’s not always immediately clear how you actually go about doing this. ", "setUp: Run once for every test method to setup clean data. Django provides test APIs to check that the correct template is being called by your views, and to allow you to verify that the correct information is being sent. Writing unit tests for the custom code (and only for the custom code) is important. In regard to views, these tests aren’t checking You should test all aspects of your own code, but not any libraries or functionality provided as part of Python or Django. Templates are hard to test, Most Add the first part of the test class (shown below) to the bottom of /catalog/tests/test_views.py. more complicated than this, it would make a lot of sense to write a fixture The patterns for testing the other models are similar so we won't continue to discuss these further. well! just by writing the tests ;) But if you’re testing code that’s complex, this So go down to He was gracious decorators.py views.py Class-based Views. This brings me to a Testing Django REST Framework. Here we should test the labels for all the fields, because even though we haven't explicitly specified most of them, we have a design that says what these values should be. as well do a tutorial and give back to the community at the same time. Copy the code below and paste it onto the end of the test class above. For example, if you set the variable for the author list page to 5, update the line above to: The most interesting variable we demonstrate above is response.context, which is the context variable passed to the template by the view. : Notice how he is using reverse() when referring to his URLs, this makes tests Now we have isolated views from system. the output, so it’s hard for me to get testing information. In short, the granular control that function-based views offer also requires some granular tedium to … We do that here only so that you can see the order that the setup functions are called in the console (in the following section). As of Django 1.5, the easiest way to test class-based views is using the builtin test client. This can be done using the keepdb (or shorthand -k) flag like so: # Reuse the test-database (since django version 1.8) $ python manage.py test --keepdb Note how we construct test date values around our current date (datetime.date.today()) using datetime.timedelta() (in this case specifying a number of days or weeks). Note: Here we don't actually use the database or test client. So we’re going Of course, if your project has utils, forms, Testing is an important but often neglected part of any Django project. >>> from basic.blog.models import Post, Category, >>> response = client.get(reverse('blog_index')), >>> response = client.get(reverse('blog_category_list')), >>> category = Category(title='Django', slug='django'), >>> response = client.get(category.get_absolute_url()), >>> post = Post(title='My post', slug='my-post', body='Lorem ipsum, dolor sit amet', status=2, publish=datetime.datetime.now()), >>> response = client.get(post.get_absolute_url()), that music up! We then just create the form, passing in our data, and test if it is valid. # Required to grant the permission needed to set a book as returned. should be. The field tests check that the values of the field labels (verbose_name) and that the size of the character fields are as expected. object_list again. I’m going to take one of my favorite open ', # Get second page and confirm it has (exactly) remaining 3 items, """Generic class-based view listing books on loan to current user. Let's start with one of our simplest views, which provides a list of all Authors. As we make changes and grow the site, the time required to manually check that everything works "properly" will only grow. actual URLs. test-driven and behaviour-driven development). Here are some tips. The template tags are used for injecting dynamically generated content to the Django views. test_form_renewal_date_initially_has_date_three_weeks_in_future, test_redirects_to_all_borrowed_book_list_on_success, Django Tutorial Part 9: Working with forms, Writing your first Django app, part 5 > Introducing automated testing, Workshop: Test-Driven Web Development with Django, Testing in Django (Part 1) - Best Practices and Examples, Setting up a Django development environment, Django Tutorial: The Local Library website, Django Tutorial Part 2: Creating a skeleton website, Django Tutorial Part 4: Django admin site, Django Tutorial Part 5: Creating our home page, Django Tutorial Part 6: Generic list and detail views, Django Tutorial Part 7: Sessions framework, Django Tutorial Part 8: User authentication and permissions, Django Tutorial Part 11: Deploying Django to production, Assessment: Structuring a page of content, From object to iframe — other embedding technologies, HTML Table advanced features and accessibility, Assessment: Typesetting a community school homepage, What went wrong? We should check that the initial value of the form is seeded with a date three weeks in the future, and that if validation succeeds we're redirected to the "all-borrowed books" view. In other cases you may wish to have a separate class for testing a specific use case, with individual test functions that test aspects of that use-case (for example, a class to test that a model field is properly validated, with functions to test each of the possible failure cases). Generally this means that you should test that the forms have the fields that you want, and that these are displayed with appropriate labels and help text. : GET, POST, etc. The all-borrowed view was added as a challenge, and your code may instead redirect to the home page '/'. The Django framework adds API methods and tools to help test web and Django-specific behaviour. So we have the tests that were there before, and they’re fine. The new class defines two methods that you can use for pre-test configuration (for example, to create any models or other objects you will need for the test): The test classes also have a tearDown() method which we haven't used. Django provides a small set of tools that come in handy when writing tests. While there are numerous other test tools that you can use, we'll just highlight two: There are a lot more models and views we can test. You can use a collection of tests – a test suite – to solve, or avoid, a number of problems: When you’re writing new code, you can use tests to validate your code works as expected. getting good code coverage and following best practices. In addition, automated tests can act as the first real-world "user" of your code, forcing you to be rigorous about defining and documenting how your website should behave. Here we see that we had one test failure, and we can see exactly what function failed and why (this failure is expected, because False is not True!). Django's class-based views are a welcome departure from the old-style views. Which just goes Add your own versions now, following the naming conventions and approaches shown above. If you use the form class RenewBookModelForm(forms.ModelForm) instead of class RenewBookForm(forms.Form), then the form field name is 'due_back' instead of 'renewal_date'. The test methods are run independently, with common setup and/or tear-down behaviour defined in the class, as shown below. Note how we are able to access the value of the initial value of the form field (shown in bold). The object_list on the page is thoughts on this kind of stuff. If the condition does not evaluate as expected then the test will fail and report the error to your console. This is a very minor bug, but it does highlight how writing tests can more thoroughly check any assumptions you may have made. For example: Create a file structure as shown above in your LocalLibrary project. Open our /catalog/tests/test_models.py, and replace any existing code with the following test code for the Author model. Django Testing Tutorial - Testing Views #3 - Duration: 16:28. blog_category_list, and pull the old object_list trick. You should get This is a pretty simple test suite at the moment. So we have some Generic views in our application, should we test them? There is a lot more to know, but even with what you've learned already you should be able to create effective unit tests for your websites. When using pytest, the test client is made available as a fixture by the pytest-django plugin. Testing in Django ¶ Automated testing is an extremely useful bug-killing tool for the modern Web developer. In this particular case the context object name was automatically defined by the get_context_object_name method in the ListView. In Django this constraint would be added to your form classes (although you can define validators for model fields and model validators these are only used at the form level if they are called by the model's clean() method. To understand how to write unit tests for Django-based websites. Note: The django.test.TestCase class is very convenient, but may result in some tests being slower than they need to be (not every test will need to set up its own database or simulate the view interaction). Nor do you need to test that the date_of_birth has been validated to be a date field, because that is again something implemented in Django. code it is remarkably well done. This article focuses on testing decorators. As a simple task, try to create a test case for the AuthorCreate view. really annoying way of testing, and I’m going to repeat that this is why doc # Create a BookInstance object for test_user1, # Create a BookInstance object for test_user2, # Manually check redirect (Can't use assertRedirect, because the redirect URL is unpredictable), test_forbidden_if_logged_in_but_not_correct_permission, test_logged_in_with_permission_borrowed_book. Django provides a test framework with a small hierarchy of classes that build on the Python standard unittest library. import and call to the test, and running python -i testfile, if you want. POST/Redirect/GET pattern; Django Test client; Testing an inline formset. Nathan has graciously included my new tests in his project, if you want to When we develop an application we devide it into functionalities and develop them independently. Let’s go poking around inside of response.context, which is a dictionary of This doesn’t look much And returning basic HTML However you would need to test any additional validation that you expect to be performed on the fields and any messages that your code will generate for errors. save it, and then test it’s view and get_absolute_url() method. output like this: So go ahead and put in the correct information in where [test] was. These essentially just check that the object name was constructed as we expected using "Last Name", "First Name" format, and that the URL we get for an Author item is as we would expect. Tip: The most important thing to learn from the test output above is that it is much more valuable if you use descriptive/informative names for your objects and methods. In this tutorial we've shown you how to write and run tests for your models, forms, and views. If you created the Author model as we described in the models tutorial it is quite likely that you will get an error for the date_of_death label as shown below. For these reasons, some software development processes start with test definition and implementation, after which the code is written to match the required behavior (e.g. Let’s go ahead However you should check the text used for the labels (First name, Last name, Date of birth, Died), and the size of the field allocated for the text (100 chars), because these are part of your design and something that could be broken/changed in future. to store the data. The class demonstrates how to construct a test case class by deriving from TestCase. The difference between FTs and unit tests. To write a test you derive from any of the Django (or unittest) test base classes (SimpleTestCase, TransactionTestCase, TestCase, LiveServerTestCase) and then write separate methods to check that specific functionality works as expected (tests use "assert" methods to test that expressions result in True or False values, or that two values are equal, etc.) that is user defined. To speed up your test-runs you can tell the management-command to reuse the test-database (and to prevent it from being created before and deleted after every test-run). Open our /catalog/tests/test_forms.py file and replace any existing code with the following test code for the RenewBookForm form. meta subject, slight tangent time. When you start a test run, the framework executes the chosen test methods in your derived classes. The first step for testing your Django views is to construct them in such a way that they are easy to test. Most importantly we've provided a brief summary of what you should test, which is often the hardest thing to work out when you're getting started. This tutorial shows how to write automated tests for Django, by adding a number of tests to the LocalLibrary website. The text shown in bold above would not normally appear in the test output (this is generated by the print() functions in our tests). Consider our form for renewing books. You should not normally include print() functions in your tests as shown above. It’s always good to test if you can save your objects I would love some feedback, and to We start by importing our form and some Python and Django libraries to help test time-related functionality. The code to grant permissions during tests is shown in bold: Add the following tests to the bottom of the test class. Run the tests now. They perform a The Local Library currently has pages to display lists of all books and authors, detail views for Book and Author items, a page to renew BookInstances, and pages to create, update, and delete Author items (and Book records too, if you completed the challenge in the forms tutorial). feeds, and other things like that, you can and should probably test those as test_logged_in_with_permission_another_users_borrowed_book, # Check that it lets us login. Today is the start of a So I’m going to be writing some tests for Nathan Borror’s Basic Blog. An simple way of testing this view is using the Django test client. hurdle. The Django unit test runner. Django URL resolving and urls.py. : As you can see, we’re testing to make sure that search works. However if you're using a test-driven development process you'll start by writing tests that confirm that the view displays all Authors, paginating them in lots of 10. : include and similar tags result in a check for testcase classes, there is The best base class for most tests is django.test.TestCase. As we make changes and grow the site, the time required to manually check that ever… Note: You can also do this by changing your settings file database Once we have the response we query it for its status code, the template used, whether or not the response is paginated, the number of items returned, and the total number of items. Note: Change the label for the date_of_death field (/catalog/models.py) to "died" and re-run the tests. Just write tests as regular functions. Here we first use SetUp() to create some user login accounts and BookInstance objects (along with their associated books and other records) that we'll use later in the tests. Manage test dependencies with fixtures. Half of the books are borrowed by each test user, but we've initially set the status of all books to "maintenance". to them. The post data is the second argument to the post function, and is specified as a dictionary of key/values. Similarly while we trust that Django will create a field of the specified length, it is worthwhile to specify a test for this length to ensure that it was implemented as planned. Running the test suite with pytest offers some features that are not present in Django’s standard test mechanism: Less boilerplate: no need to import unittest, create a subclass with methods. """, 'catalog/bookinstance_list_borrowed_user.html'. Many applications have business logic intertwined with view logic such as parameter validation and response construction. Note: If you set the paginate_by variable in your /catalog/views.py file to a number other than 10, make sure to update the lines that test that the correct number of items are displayed in paginated templates above and in following sections. When you go ahead and run the tests your should find some Testing DRF is very similar to testing Django views. I As websites grow they become harder to test manually. To validate our view behaviour we use the Django test Client. Run your tests to be sure, and Some of the things you can do with the test … If you want to get more information about the test run you can change the verbosity. model = Potato. We need to get some data into the Practical Django Testing Examples: Views¶ This is the fourth in a series of Django testing posts. see, for this simple stuff, it isn’t really a huge deal doing testing this Once decorators and views are separated, we can unit test the views. That was the topic of the post before. Here you'll see that we first import TestCase and derive our test class (AuthorModelTest) from it, using a descriptive name so we can easily identify any failing tests in the test output. code is outputting the correct value. tests you can just throw an import pdb; pdb.set_trace() in your code and Django also provides an API (LiveServerTestCase) and tools for using different testing frameworks, for example you can integrate with the popular Selenium framework to simulate a user interacting with a live browser. The rest of the functions test that the form is valid for renewal dates just inside the acceptable range and invalid for values outside the range. In the case of get_absolute_url() you can trust that the Django reverse() method has been implemented properly, so what you're testing is that the associated view has actually been defined. into pdb with a >>> import pdb; pdb.set_trace() in the test, i can’t see So how are we going to improve this testing of views? Django's test framework can help you write effective unit and integration tests — we've only scratched the surface of what the underlying unittest framework can do, let alone Django's additions (for example, check out how you can use unittest.mock to patch third party libraries so you can more thoroughly test your own code). 16:28.
