func TestMyFunction(t *testing.T) { c := gocheck.C(t) result, err := MyFunction() if err != nil { c.Fatal("An error occurred: ", err) } c.Assert(result == expected, gocheck.Equals, true) }In this example, the "MyFunction" function is being tested, and any errors that occur during its execution will cause the test to fail immediately thanks to the use of the "Fatal" function from the gocheck package. Overall, the gocheck package provides a useful set of tools for testing Go applications with a high degree of precision and control.
