assert is Go package that provides convenience methods
for writing assertions in standard Go tests.
You can write this test with assert:
func TestSomething(t *testing.T) {
i, err := doSomething()
assert.NoErr(t, err)
assert.Equal(t, i, 123, "returned integer")
}Instead of writing this test with only the standard testing library:
func TestSomething(t *testing.T) {
i, err := doSomething()
if err != nil {
t.Fatalf("error encountered: %s", err)
}
if i != 123 {
t.Fatalf("returned integer was %d, not %d", i, 123)
}
}
