Writing Thorough Test Cases

A test case is a statement that describes what the test will be performing. A test script is part of a test case and are the granular steps to perform the test case. A test case should aim to exercise as much of a set of requirements as possible, while still being concise.

I taught myself everything from the Help contents.

Each day I opened QBASIC was like an adventure. “What can I do today?” I would wonder. I remember teaching myself, and not quite understanding, arrays and data types. Continue reading
