Infosys Certified Espresso Tester

While preparing the automation testing environment for writing Espresso scripts, what are the major components required by the testing team for setting up the testing framework using Espresso? (Choose 2)

Espresso can be used to test mobile apps written in which of the following languages?

1. Java

2. Kotlin

3. Swift

4. Objective C

What are the different types of tests can be developed in Android Studio?

Which of the following is NOT a Text based matcher?

Consider the below code snippet:

@Test

public void changeText_sameActivity() {

// Type text and then press the button.

onView(withId(R.id.editTextUserInput))

.perform(typeText(stringToBetyped), closeSoftKeyboard());

onView(withId(R.id.changeTextBt)).perform(click());

// Check that the text was changed.

onView(withId(R.id.textToBeChanged))

.check(matches(withText(stringToBetyped)));

In this code what is onView() method going to return?

Which library is needed for using Matcher objects in Espresso Framework?

Out of all the classes used in Espresso framework, which is the one used to launch the application UI on the android app?

While running Espresso test cases, we need to use JUnit. To use JUnit4 classes, we have to specify AndroidJunitRunner as the default test instrumentation runner in the project. Out of the following code snippets, pick the correct one that does this required task without throwing any error:

Consider the following code snippet :-

onView(withId(R.id.button_signin));

In this code snippet we are trying to find an object/element using resource id. As android resource ids are not guaranteed to be unique. In our attempt to match to a resource id used by more than one view, Espresso gives the following outcome:

Identify the sample code with the correct usage of hasErrorText() method that accepts an argument of type Matcher<String> which refers the view’s (EditText) error string value and returns a matcher which matches the view using error string of the view. Also, It applies to TextView only.
