Should I use CI to run API tests on every commit?

Yes—if the API tests are reasonably fast, reliable, and deterministic, running them in CI on every commit is a very good idea.
Why it’s useful
- Catches regressions early before they merge or reach staging/prod
- Gives fast feedback to developers
- Prevents “it worked on my machine” issues
- Helps enforce API contract stability
Good candidates for every-commit CI
Run these on each commit:
- Unit tests
- Smoke API tests
- Contract tests
- A small, fast subset of integration/API tests
What not to run on every commit
Avoid full suites that are:
- Slow (e.g. 20–60+ minutes)
- Flaky
- Dependent on unstable external systems
- Expensive to spin up
Those are better for:
- Pull request / pre-merge CI
- Nightly builds
- Scheduled runs
- Post-deploy checks
Practical recommendation
A common approach is:
- Every commit: fast API smoke/contract tests
- Every PR: broader API integration tests
- Nightly: full regression suite
- After deployment: end-to-end production-like checks
Rule of thumb
If a test suite:
- runs in a few minutes,
- is isolated,
- and gives meaningful signal,
then it’s a great fit for every commit.
If you want, I can suggest a CI test strategy for your specific API stack (REST/GraphQL, microservices, etc.).
