AlertDialog is not getting launched properly(distorting app UI) when i am trying to launch it while doing Espresso test

问题

I am trying to test Alert dialog launch code on a fragment button click and as mentioned in the question title it is distorting up the UI whenever i run this test. the layout doesn't appear properly just some icons without the background of the Alertdialog box appears and no text is being displayed.

Here's the test:

    @Test
    fun mytest() {
        //on this click dialog should launch
        onView(withId(R.id.button)).perform(click())
        
        //below line verifies whether the dialog has been launched or not
        onView(withText(R.string.name)).check(matches(isDisplayed()))
    }

So please tell me what I am doing wrong here.
