Espresso tests are written in Java and are executed on the device or emulator. Espresso test code is very easy to write and maintain. It is also very fast. Espresso tests are written as JUnit tests, which means they can be run with other JUnit tests in the same test suite. Here we have used the onView() method of the Espresso class to find the view in the current view hierarchy. It is used to find the view by its resource id. It also has the method to find the view by the text of the view. It also has the method to find the view by the content description of the view. The onView() method returns the ViewInteraction object. The ViewInteraction object is used to perform the action on the view. The ViewInteraction object has the method to perform the click action on the view. It also has the method to perform the long click action on the view. It also has the method to perform the double click action on the view. It also has the method to perform the swipe action on the view. It also has the method to perform the scroll action on the view. It also has the method to perform the type action on the view. It also has the method to perform the replace text action on the view. It also has the method to perform the clear text action on the view. It also has the method to perform the close soft keyboard action on the view. It also has the method
