Test cases to performClick for custom ClicklLstener

I have created one custom click listener like below:

abstract class SingleClickListener : View.OnClickListener {
    private var lastTimeClicked: Long = 0
    private val defaultInterval: Int = 1000
    override fun onClick(v: View) {
        if (SystemClock.elapsedRealtime() - lastTimeClicked < defaultInterval) {
            return
        }
        lastTimeClicked = SystemClock.elapsedRealtime()
        performClick(v)
    }

    abstract fun performClick(v: View)
}

And then in my fragment I have used like below :

binding.textview.setOnClickListener(object : SingleClickListener() {
            override fun performClick(v: View) {
                //navigate to next screen
            }
        })

Now I want to write a test case to perform this custom click. I have tried like below but it is not working and if I'll remove SingleClickListener then the same test case is working fine.

val fragmentScenario = launchFragmentInContainerAndGetFragmentScenario()
            fragmentScenario.onFragment { fragment ->
                val textview = fragment.view?.findViewById<AppCompatTextView>(R.id.textview)

                textview?.performClick()
            }

Can anyone help me how can I call custom ClickListener's performClick function through test case?

You are using SystemClock.elapsedRealtime() which returns elapsed milliseconds since boot. But in unit tests with robolectric you will have Zero for the result of SystemClock.elapsedRealtime() call. Hence, 0 - 0 < 1000 => always true in unit tests.

You can just use System.currentTimeMillis().

abstract class SingleClickListener : View.OnClickListener {

  private var lastTimeClicked: Long = 0
  private val defaultInterval: Int = 1000
  override fun onClick(v: View) {
    val now = System.currentTimeMillis()
    if (now - lastTimeClicked < defaultInterval) {
      return
    }
    lastTimeClicked = now
    performClick(v)
  }

  abstract fun performClick(v: View)
}
