func (s *MySuite) TestMyFunction(c *gocheck.C) { c.Log("Starting test...") result, err := myFunction() if err != nil { c.Errorf("Error executing myFunction: %v", err) return } c.Log("Result of myFunction:", result) c.Assert(result, gocheck.Equals, expected) c.Log("Test completed successfully.") }In this example, the Log function is used to print messages to the console during the test. The Errorf function is used to log an error message if there is an error executing the myFunction. The Assert function is used to check the result of myFunction against the expected value. Overall, Launchpad.net/gocheck is a useful package library for writing and running tests in Go, and the C Log module provides helpful logging functionality to assist with testing and debugging.
