func BenchmarkAdd(b *testing.B) { for n := 0; n < b.N; n++ { Add(1, 2) } }
func TestSlowDatabase(t *testing.T) { // Create a monitor that tracks how long each test takes monitor := testing.NewGlobalMonitor(t) // Run a function that accesses the database (assuming it's slow) SlowDatabaseFunction() // Check if the test took longer than expected if monitor.ElapsedTime() > time.Second { t.Errorf("Test took too long: %v", monitor.ElapsedTime()) } }In this example, a monitor is created to track how long the test is taking. If the elapsed time exceeds one second, an error is reported. This can help identify slow database queries or other performance issues. Overall, the testing package in Go provides a powerful set of tools for developing and maintaining high-quality code.
