Test Driven Development correct answers A way of developing software where the test cases are
developed, and often automated, before the software is developed to run those test cases.
Stages of Test Driven Development correct answers -Write tests for the code you intend to make
-Run the tests to ensure they fail-want to make sure it fails in a way you expect, to ensure the test
itself is well formed
-Write the code and run the tests-once the code is written, all the tests should pass correctly, so
extraneous functionality falling outside of the tests is avoided
-Refactor the code, improving the implementation
