Testa Rossa

TestaRossa is a simple utility on top of Go's standard testing library that prints the full/path/to/the/source/file/of/the/unit_test.go:line of a failed assertion, which in VSCode is a clickable link. Unlike t.Log, output is printed using fmt.Printf during the execution of the test rather than at its conclusion.

TestaRossa supports a functional pattern:

func TestMe(t *testing.T) {
    testarossa.Equal(t, 1, 0, "You are not the %d", 1)
    err := errors.New("This is bad")
    testarossa.NoError(t, err)

    droids := 1234
    testarossa.FailIf(t, droids != 0, "These are not the droids you are looking for")
    err = errors.New("This is really bad")
    testarossa.FatalIfError(t, err)
}

as well as a more object-oriented pattern:

func TestMe(t *testing.T) {
    tt := testarossa.For(t)
    tt.Equal(1, 0, "You are not the %d", 1)
    err := errors.New("This is bad")
    tt.NoError(err)
}

Example test output:

--- FAIL: TestMe
    /my_projects/github.com/microbus-io/testarossa/my_test.go:10
    Expected '1', actual '0'
    You are not the 1
--- FAIL: TestMe
    /my_projects/github.com/microbus-io/testarossa/my_test.go:12
    Expected no error
    This is bad
--- FAIL: TestMe (0.00s)
FAIL
FAIL	github.com/microbus-io/testarossa	0.173s
