Writing Effective Tests and Version Control
Traits of Effective Tests
| Trait | Why It Helps |
|---|---|
| Descriptive test names | Failures are easy to understand at a glance |
| One assertion focus per test | Pinpoints exactly what broke |
| Reusable helper functions | Avoids duplicated logic across requests |
Using Version Control
Exporting collections as JSON and committing them to a Git repository lets teams track changes over time, review edits through pull requests, and roll back if something breaks.
Working with Postman's Git Integration
Postman also supports linking a workspace directly to a Git repository, so changes made in the app can be committed and pushed without manual exporting.
Code Review for Tests
Treating test scripts like application code - reviewing changes before merging - helps catch mistakes in assertions before they reach the whole team.
Even well-written tests will occasionally fail - knowing how to debug requests efficiently is the next essential skill.
