Slider testing is not supported in espresso

[iliaskomp]

Description

There is a Slider view included in the Material Design website: https://m3.material.io/components/sliders/overview

I would like to test some functionality regarding Slider via instrumentation tests.
However, there are no ViewAssertions or ViewInteractions that specifically support slider values.

For assertions that's manageable since some custom assertions can be made.

For interactions though, to my understanding there is no way to change the slider values. I can obtain the slider instance and change value parameter to a new value. But this does not simulate the user's "click" on that value and therefore no actions (e.g. screen transitions) based on that click are triggered.

I'm not very familiar with material but in general android libraries should provide their own testing APIs, built on top of core espresso.

Have you tried filing an issue against material? I think this might be their github https://github.com/material-components/material-components-android
