Q: In the basic workflow for test driven development (TDD), what happens in the second step?

Correct. In the second step in the basic TDD workflow, developers write just enough code to make the unit test pass.

Q: To create a DevOps pipeline, which type of testing must developers use for all testing?

Correct. To create a DevOps pipeline, developers must automate all testing. That way, they can easily identify bugs well before the bugs would otherwise reach production.

Q: Which of the following testing frameworks supports multiple programming languages?

Correct. The xUnit testing framework supports multiple programming languages, such as Python, Java, C, and C++.

Q: Which of the following commands can developers use to invoke Python with the unittest module and to run all the tests in the test folder?

Correct. The command python -m unittest discover will invoke Python with the unittest module and run all the tests in the test folder.

Q: Which of the following features is available in Nose but missing in unittest?

Correct. With Nose, developers can add color coding and other formatting features to test output. This feature is not available in unittest.

Q: In which of the following ways do testing frameworks help developers build assertions?

Correct. Testing frameworks provide tools, such as the TestCase class in unittest, that simplify testing conditions.

Q: What purpose do assertions serve in testing?

Correct. Developers use assertions as checks to determine if the results of a test have passed or failed.

Q: What is the purpose of using sad paths in testing?

Correct. Developers use sad paths to verify that a function responds to exceptions appropriately and without breaking.

Q: Test fixtures provide which of the following benefits for testing?

Correct. With test fixtures, developers can ensure that the system resets after each test. In turn, this reset ensures repeatable results because every test runs from the same initial state.
