How Can I Disable Go Test Caching or Force Test Reruns?

Disabling Test Caching or Forcing Test Reruns

When executing the "go test" command repeatedly, you may encounter a situation where the second and subsequent runs appear to use cached results without actually executing the tests. This can be frustrating, especially if you are making changes to your code and want to ensure that the tests are running successfully.

Solution:

Go provides several options to force test reruns or disable test caching:

• Invalidate Test Cache: Running "go clean -testcache" expires all previously cached test results. This is the most straightforward way to ensure that all tests are executed every time.
• Use Non-Cacheable Flags: Including non-cacheable flags in your test run can prevent caching. The recommended approach is to use "-count=1". This flag specifies that the tests should be executed once for each target package and that test results should not be cached.

Example:

go test -v -count=1

• Test Cache Invalidation Criteria: It's important to note that changes in your code or test code automatically invalidate cached test results. Additionally, using local files or environment variables in your tests can also affect cache invalidation. As a result, you shouldn't typically need to manually invalidate the test cache.
