How do you write test cases in Python?

TestCase is used to create test cases by subclassing it. The last block of the code at the bottom allows us to run all the tests just by running the file. Basic terms used in the code : assertEqual() – This statement is used to check if the result obtained is equal to the expected result.

When to use testing instead of running code?

When something goes wrong or has to be changed, and if your code has a good set of tests, you or other maintainers will rely largely on the testing suite to fix the problem or modify a given behavior. Therefore the testing code will be read as much as or even more than the running code.

How are functional code and test code tested?

By construction, functional code and test code are tested one against the other. One problem remains: the case of common mode bugs, when a bug in functional code is hidden by a bug in test code. TDD is not immune to this effect. This is why testing is usually performed at multiple levels by different people in order to decrease this probability.

Which is the first step in debugging your code?

The first step when you are debugging your code is to write a new test pinpointing the bug. While it is not always possible to do, those bug catching tests are among the most valuable pieces of code in your project. Use long and descriptive names for testing functions.

Which is the best way to write a test script?
