[BUG] Unexpected Goroutine Leak in OpenFeature Go SDK in Test Environment. #471
Description
Brief Description
The event executor initiates a background goroutine during package initialization to manage FeatureProvider events, which remains active as no mechanism exists to signal its completion during testing..
Observed Behavior
A goroutine remains active after test completion:
- Goroutine state: chan receive
- Test suites using goleak.VerifyTestMain(m) fail during goroutine leak verification.
Stack trace
goleak: Errors on successful test run: found unexpected goroutines:
[Goroutine 21 in state chan receive, with github.com/open-feature/go-sdk/openfeature.(*eventExecutor).startEventListener.func1.1 on top of the stack:
github.com/open-feature/go-sdk/openfeature.(*eventExecutor).startEventListener.func1.1()
/Users/denis/go/pkg/mod/github.com/open-feature/go-sdk@v1.17.0/openfeature/event_executor.go:278 +0xb0
created by github.com/open-feature/go-sdk/openfeature.(*eventExecutor).startEventListener.func1 in goroutine 1
/Users/denis/go/pkg/mod/github.com/open-feature/go-sdk@v1.17.0/openfeature/event_executor.go:277 +0x60
Expected Behavior
All goroutines should be properly cleaned up after test execution, leaving no lingering background processes.
