How to Force Retesting or Disable Test Caching in Go?

Force Retesting or Disable Test Caching in Go

The Go testing environment caches test results by default, allowing subsequent runs to use the cached results to improve efficiency. However, in certain scenarios, you may want to force retesting or disable test caching.

Force Retesting

When running go test multiple times, you may notice that subsequent runs do not actually execute the tests and instead display cached results. To force retesting, you can use the following options:

• go clean -testcache: This command expires all cached test results, forcing subsequent test runs to execute all tests.
• go test -count=1: The -count flag specifies the number of times to run each test. Using -count=1 will execute each test once, disregarding any cached results.

Disable Test Caching

To permanently disable test caching, you can use the -nocache flag when running go test. This flag prevents the test results from being cached and forces the tests to be executed every time.

Note

It's generally not necessary to manually disable test caching. Changes in your code or test code will automatically invalidate cached test results. Therefore, you should only need to use the methods described above if you encounter specific circumstances where you require forced retesting of all cached tests.
