ass is a non-inflated testing lib making error assertions easier. It basically does one thing:
ass.Err(t, ...)As you can see, it spells assErrt, which is convenient and conveys the intent very clearly. Writing ass is also 50% more efficient than writing assert.
ass accepts many different inputs (one at a time though, a bbl companion lib might exist in the future if some expansion is needed), making it very practical when doing table driven testing:
err := f()
// Assert no error
ass.Err(t, err, nil)
ass.Err(t, err, "")
// Substring matching
ass.Err(t, err, "an error occurred")
// errors.Is matching
ass.Err(t, err, ErrValue)
// errors.As matching
ass.Err(t, err, reflect.TypeOf(&ErrType{}))Please star this repo if you like ass.
