While capturing code coverage metrics from unit tests is a straightforward process, the same cannot be said for integration tests executed against the binary itself. However, a workaround exists that leverages the testing framework.
The key lies in coercing integration tests into the testing framework by:
Creating a Test File:
Execute the main() function as a goroutine:
func TestMainApp(t *testing.T) { go main() // Start integration tests here }
Executing Integration Tests:
Collecting Coverage:
For further insights into this approach, refer to the article "Go coverage with external tests." While it may have been written a year ago, the underlying concepts remain relevant.
