Testing Snackbar show with Espresso

May 10, 2023 by Tarik

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)))
