How to stop all tests from inside a test or setUp using unittest? To start off with a basic example, we’ll use the following file/directory structure: Here is the source code for basicfunction.py: To start, let’s create a really basic unit test file that doesn’t even care about basicfunction.py yet: The unit test file starts off by importing the built-in ‘unittest’ module from python. One of the things I would like to do is to stop all the tests from running inside of a test, and inside of a setUpClass() method. Though you won't get the usual test reports of the tests run so far, a very easy way to stop the test run from within a TestCase method is simply to raise KeyboardInterrupt inside the method. You can see how only KeyboardInterrupt is allowed to bubble up inside unittest's test runner by looking at CPython's code here inside testPartExecutor(). Somewhat related to your question, if you are using python 2.7, you can use the -f/--failfast flag when calling your test with python -m unittest. I was not aware of that testing framework. Sometimes if a test fails, the program is so broken it is no longer of any use to keep testing, so I want to stop the tests from running. Step 3: Create a testcase by subclassing unittest.TestCase.

There are a lot of nuances to this setup, especially when getting the module imports to work correctly. It achieves this and more through the following concepts: 1. Remember in the previous example where we had the source code and unit test files in the same directory? It starts with a basic example to show how unit tests execute and then moves on to a typical file/directory structure for a python project. In order to use this nice feature, you need to have your directory structure set up similar to our current structure, with the __init__.py files added: Be very careful when naming “__init__.py”, as I ran into a very frustrating bug when I had only one underscore after init in my test directory (…/test/__init_.py instead of …/test/__init__.py). rev 2020.12.18.38240, Stack Overflow works best with JavaScript enabled, Where developers & technologists share private knowledge with coworkers, Programming & related technical career opportunities, Recruit tech talent & build your employer brand, Reach developers & technologists worldwide, I use this to abort the test run before running any tests if the application under test is configured with prod settings.

To re-cap, here is our directory structure: Here is the content of …/project2/project2/basicfunction.py: Here is the content of …/project2/test/test_basicfunction.py: Change directories into your top-level directory (…/project2) and run the unit test discovery command: Darn, it didn’t work! For now, it just has a simple ‘assertTrue’ statement that will always pass. This can feel like unnecessary repetition. Start by importing the class of interest (BasicFunction) from the basicfunction.py file, add a setUp() method to create a local instance of this class, and then write a third unit test to check the initialization of this class: Be careful with how you import the BasicFunction class, as simply using “import basicfunction” or “import BasicFunction” will give you an error, such as: Once the import is correct (“from basicfunction import BasicFunction”), here’s the output that you get from running the unit tests: Here are a few addition test cases that show that we can fully test all of the methods within the BasicFunction class: Here’s the output of running the unit tests now that we have 5 test cases: Good progress!
