Test-Driven Development
Write the behavior case first. Watch the test fail for the right reason. Then write the smallest useful code to make it pass.
This is an implementation skill, not the place to design a whole test suite. Use high-level-testing-strategy first when test cases or scope are unclear.
For coding-related work, load engineering-principles before this skill. Use
TDD as one execution technique inside the broader engineering defaults.
