Following example calls assertEquals() function. Step 5 − Each test calls assert function of TestCase class. Step 4 − Define a test as a method inside the class. Step 3 − Create a testcase by subclassing unittest.TestCase. In the following example, add() function is to be subjected to test. Step 1 − Import the unittest module in your program. The following steps are involved in writing a simple unit test − The runner may use a graphical interface, a textual interface, or return a special value to indicate the results of executing the tests. Test runner − This is a component which orchestrates the execution of tests and provides the outcome to the user. Test suites are implemented by the TestSuite class.
This is used to aggregate tests that should be executed together. Test suite − This is a collection of test cases, test suites, or both. unittest provides a base class, TestCase, which may be used to create new test cases. This checks for a specific response to a particular set of inputs. Test case − This is the smallest unit of testing. This may involve, for example, creating temporary or proxy databases, directories, or starting a server process. Test fixture − This represents the preparation needed to perform one or more tests, and any associate cleanup actions. To achieve this, unittest supports the following important concepts − The unittest module provides classes that make it easy to support these qualities for a set of tests.

'unittest' supports test automation, sharing of setup and shutdown code for tests, aggregation of tests into collections, and independence of the tests from the reporting framework.
