Test Case Peer Review
Test case peer review has another tester or team member review newly written test cases before they're executed — checking for clarity, completeness, correct expected results, and coverage gaps — catching problems with the test itself before it's run, the same way code review catches problems before code ships.
A test case with a vague expected result, a missing precondition, or an incorrect assumption about system behavior can pass or fail for the wrong reasons entirely — peer review catches these test-authoring mistakes early, before time is spent executing a flawed test case that doesn't actually verify what it was meant to.
It's a lightweight, high-leverage practice — a second pair of eyes on a written test case takes minutes and often surfaces both errors in the test itself and, sometimes, entirely new test cases the original author hadn't thought to include.
