Unittest-xml-reporting (aka xmlrunner) A unittest test runner that can save test results to XML files in xUnit format. The files can be consumed by a wide range of tools, such as build systems, IDEs and continuous integration servers. The unittest module can be used from the command line to run single or multiple tests. Python -m unittest test1 python -m unittest testmodule.TestClass python -m unittest testmodule.TestClass.testmethod unittest supports the following command line options. For a list of all the command-line options, use the following command −. Project: pywren-ibm-cloud Author: pywren File: tests.py License: Apache License 2.0.
There are several different ways to run the tests written using the Python unittests package.
Python Unittest Run Tests In Order
Let's test this code, with the obvious bug in it:
Data-flair.training › Blogs › Python-unittestUnit Testing With Python Unittest – Example & Working
examples/python/unit_test/app.py
Python -m unittest tests/testmymodule.py. You can run tests with more verbosity by passing in the -v flag: python -m unittest -v testmymodule. When executed without arguments, Test Discovery is started: python -m unittest. For a list of all the command-line options available below command is used: python -m unittest -h. Unit Testing using Unittest in Python. In this tutorial, we are going to learn about Unit Testing using the unittest built-in module. Testing plays a major role in software development. You will know the issues before going to the production itself. We'll learn the basics of testing in Python using the built-in module called unittest.
We can write a test-case like this:
examples/python/unit_test/test_app.py
Python Unittest Test Runner
Running with unittest.main
The 'standard' or 'default' way to run the test is by calling unittest.mainas in this code:
examples/python/unit_test/with_main.py
It can be executed by running that file using python with_main.py
The result looks like this:
If we check the exit code it is
Running TestSuite with unittest.TextTestRunner
examples/python/unit_test/with_text_test_runner.py
Just calling >unittest.TextTestRunner().run(suite) won't exit thescript and thus won't set the exit code. This is not a good idea as externaltools (e.g. CI systems) will rely on the exit code to determine if runningthe tests was successful or not.
How To Test Python Code
So we capture the result of the test run in a variable and then call thewasSuccessful method on it to determine what should be the exit code.
