Slider instrumentation testing is not supported (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.

Expected behavior:
I would expect to be able to perform a click on a slider value via a provided api, something like this:

onView(withId(R.id.slider)).perform(clickSliderValue(10.0f))
