Testing Snackbar show with Espresso

Question

Is there a way to test using Espresso that the snackbar shows up with the right text?

I have a simple call to create a snackbar

Snackbar.make(mView, \"My         


        

Answer 1

This worked for me, please try.

onView(allOf(withId(android.support.design.R.id.snackbar_text), withText("My text")))
            .check(matches(isDisplayed()));

If you use AndroidX, please use the following:

onView(withId(com.google.android.material.R.id.snackbar_text))
        .check(matches(withText(R.string.whatever_is_your_text)))
