The module contains the core framework classes that form the basis of the test cases and suites (TestCase, TestSuite and so on), and also a text-based utility class for running the tests and reporting the results (TextTestRunner). Then there is a 'shared log' and 'per-test log'. And since we want our set_name test to execute first, we have named our test case functions as test_0_set_name and test_1_get_name. Hi @Cosmin. It allows automation, sharing of the setup and exit code for tests, and independent tests for every framework. Let's see the brief intro about each method that we are going to write. FAIL – This means that the test did not pass and an AssertionError exception is raised. This method tests whether two strings are equal or not using assertEqaul method of unittest.TestCase. Here, in the output the “.” on the first line of output means that a test passed. I'll get into the details later. This simple helper facilitates testing Terraform modules from Python unit tests, by wrapping the Terraform executable and exposing convenience methods to set up fixtures, execute Terraform commands, and parse their output. Unit Testing is the first level of software testing where the smallest testable parts of a software are tested. The purpose of this code is to have the name of the test cases, their indexes, as well as the results (Pass, Fail, Error) as a list.

'err' is a tuple of values as, "Called when a test has completed successfully". The collections, contain tuples of (testcase, exceptioninfo), where exceptioninfo is the. Or earlier. Unit tests should run fast so the entire test suite can be run quickly. To begin with, your interview preparations Enhance your Data Structures concepts with the Python DS Course.
