Description

Context: In my tests, I wanted to replace all my assertInvalid assertions by assertOnlyInvalid then specify validation messages so I played around with parameters and tried to see if I could get away with doing assertOnlyInvalid('field', __('message')) instead of passing an array.

But I found the following a bit weird:

I know this is not the proper way to use this method but that test still passes. In this example, the anomaly is pretty obvious (w/ typos and random letters) but let's say we're an innocent dev and tried the following:

Obviously, there's no validation message with this key.
Since the test is passing and it looks okay to our eyes, it would pass by our radar.

Steps To Reproduce

• Install any Starter Kit, I used the React one here.
• Pick any test with assertSessionHasErrors and replace it with assertOnlyInvalid
• Pass several arguments to it (do not use an array)
