Hey @gizmo-rt!
The test you added is only adding a coverage of 30% to the file main.go. The middlewares code are commented somehow and we only have one handler registered. Can you please try and uncomment the code to write test for it along with handler.

@Umang01-hash The commented example seems like an alternative method to use the auth middleware.
Either we can keep one of those examples or decouple and include both. Thoughts ?

@gizmo-rt what i meant to say was we should add tests that directly cover the main() function. You don't need to uncomment the alternatives - instead, add a test like this:

func Test_MainEndToEnd(t *testing.T) {
    serverConfigs := testutil.NewServerConfigs(t)
    
    // Run main() in a goroutine to avoid blocking
    go main()
    
    // Allow time for server to start
    time.Sleep(100 * time.Millisecond)
    
    client := &http.Client{Timeout: 200 * time.Millisecond}
    
    // Test valid API key
    t.Run("Valid API Key", func(t *testing.T) {
        req, _ := http.NewRequestWithContext(t.Context(), http.MethodGet,
            serverConfigs.HTTPHost+"/test-auth", http.NoBody)
        req.Header.Set("X-Api-Key", "valid-api-key")
        
        resp, err := client.Do(req)
        if err != nil {
            t.Fatalf("Error making request: %v", err)
        }
        defer resp.Body.Close()
        
        assert.Equal(t, http.StatusOK, resp.StatusCode)
    })
