Table-Driven Test Guidelines

Table-driven tests define multiple test cases in a slice of structs, then iterate over them executing the same test logic. This makes it easy to add cases, improves readability, and reduces duplication.

When to use table-driven tests:

• You have 3+ similar test cases that vary by inputs/outputs
• Tests follow the same logic pattern with different data
• Most unit and integration tests benefit from this structure

When to skip:

• Only 1-2 simple test cases (overhead not worth it)
• Each test requires completely different logic
• Test setup/teardown varies significantly between cases

Not the same as: Datadriven tests (different library with testdata files)
