Go Testing Skill

Go testing follows a 4-phase workflow: understand what needs testing, write idiomatic tests, run and verify, review quality. Every function with multiple test cases uses table-driven pattern. Every helper calls t.Helper(). Every concurrent test runs with -race.

Goal: Determine what needs testing and the appropriate test strategy.

Step 1: Identify test scope

• What function/method/package is being tested?
• Is this a new test, modification, or coverage gap?
• Are there existing tests to follow as patterns?
