It was still called py.test until August 2016, but following the release of pytest 3.0.0 the recommended command line entry point became pytest. [3] Pytest has been classified by developer security platform Snyk as one of the key ecosystem projects in Python due to its popularity.

Tester: Yes: Yes [462] PHP library for unit-testing (in console and browser), simplified variant of PHPUnit. With ability to handle errors and exceptions in tests. PhpInlineTest: No: No [463]
Unit testing is the cornerstone of extreme programming, which relies on an automated unit testing framework. This automated unit testing framework can be either third party, e.g., xUnit, or created within the development group. Extreme programming uses the creation of unit tests for test-driven development. The developer writes a unit test that ...
The following code contains two assertions, x > 0 and x > 1, and they are indeed true at the indicated points during execution: x = 1 ; assert x > 0 ; x ++ ; assert x > 1 ; Programmers can use assertions to help specify programs and to reason about program correctness.
In computer software testing, a test assertion is an expression which encapsulates some testable logic specified about a target under test. The expression is formally presented as an assertion, along with some form of identifier, to help testers and engineers ensure that tests of the target relate properly and clearly to the corresponding specified statements about the target.
This can be modified by options to the doctest runner. In addition, doctest has been integrated with the Python unit test module allowing doctests to be run as standard unittest testcases. Unittest testcase runners allow more options when running tests such as the reporting of test statistics such as tests passed, and failed.
Therefore, unit test code is usually located in the same project or module as the code being tested. In object oriented design this still does not provide access to private data and methods. Therefore, extra work may be necessary for unit tests. In Java and other languages, a developer can use reflection to access private fields and methods. [13]
In software engineering, code coverage, also called test coverage, is a percentage measure of the degree to which the source code of a program is executed when a particular test suite is run.
