Smoke Test

A quick, shallow test run after a build or deployment to confirm the most critical functions work.

Definition

Smoke tests verify the application starts and key endpoints respond before deeper testing or traffic shift. They are often used as post-deployment verification.

Example

After deploying, the pipeline calls /healthz and the login endpoint and aborts if either fails.

Exam tip

Smoke tests are broad and shallow; regression tests are deep and comprehensive.
