Assertion utilities for testing in Go
Write your test as usual.
func TestAdd(t *testing.T) {
a := 1
b := 2
actual := Add(a, b)
expected := 3
if actual != expected {
t.Errorf("need %d, got %d", expected, actual)
}
if actual <= a {
t.Errorf("%d < %d is false", actual, a)
}
if actual <= b {
t.Errorf("%d < %d is false", actual, b)
}
}Run the test with -v flag, you will see the output like bellow.
=== RUN TestAdd
example_test.go:14: need 3, got 2
example_test.go:22: 2 < 2 is false
--- FAIL: TestAdd (0.00s)
Refactor by using golang must!
func TestAdd(t *testing.T) {
a := 1
b := 2
actual := Add(a, b)
expected := 3
must := should.New(t)
should.Equal(expected, actual)
should.True(actual <= a)
should.True(actual <= b)
}Run the test with -v flag, you will see the output like bellow.
=== RUN TestAdd
example_test.go:16: need 3, got 2
example_test.go:17: need true, got false
--- FAIL: TestAdd (0.00s)
Your test more clean and clear, now 👍
