How Can I Force Go Tests to Rerun and Avoid Caching?

Disabling or Forcing Retesting in Go Tests

When running Go tests multiple times, it's observed that cached test results are used instead of performing the tests again. This can be inconvenient if you desire to re-execute the tests for verification or debugging purposes.

Force Test Execution

To force Go tests to always run and prevent caching, there are two primary approaches:

• Clean Test Cache: Execute go clean -testcache to invalidate all cached test results.
• Use Non-Cacheable Flags: Add the non-cacheable flag -count=1 to your test run. This flag ensures that the tests will be executed once for each run.

Test Caching Behavior

It's worth noting that Go automatically invalidates cached test results under certain conditions, including changes to the source code, test code, local files, or environment variables. As such, it's generally not necessary to manually invalidate the test cache unless explicitly required.
