The work people skip.
FOR TESTS
"Write tests for this. Cover the normal case, the edge cases, and failure."
Generated tests are a starting point. Check they actually test something.
THE COMMON PROBLEM
Tests that pass whatever the code does. A test asserting a variable exists rather than that a behaviour happens.
Check each test would fail if the code were wrong.
FOR DOCUMENTATION
"Write documentation for this. Reader: [who]. Include what it does, how to use it, what it requires, and what can go wrong."
WHY THIS IS A GOOD USE
Documentation is the work that never rises to the top of the list.
Generating a first draft makes it happen.
WHAT TO VERIFY
Every example, by running it Every claim about behaviour
FOR README FILES
"Write a README covering installation, configuration, usage and troubleshooting."
Then correct it against what the software actually does.
