1. Express Automation Using Espresso
2. ➢ What and how ➢ Components of espresso ➢ Extensions and others ➢ Pros and cons
3. WHAT • A UI test framework (part of the Android Testing Support Library) • To create automated UI tests for Android app • Gradle + Android Studio support • Simple and Extensible API remains open for customization
4. HOW • Install android support repository • In build.gradle dependencies androidTestCompile 'com.android.support.test.espresso:espresso- core:2.2.2' androidTestCompile 'com.android.support.test:runner:0.5' • Under default config testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" • Create class with @RunWith(AndroidJUnit4.class) • Specify Activity to be tested with @Rule and Create test functions with @Test
6. Main components of Espresso : • Espresso – Entry point to interact with views and APIs not tied to view • ViewMatchers – To identify view within view hierarchy • ViewActions – Do action on view • ViewAssertions – Verify or Assert on view
7. • OnView • OnData • PressBack • CloseSoftKeyboard Espresso
8. withId(R.id. error_msg ) withContentDescription ("More options" ) allOf (withId (R.id. error_msg_text ),withEffective Visibility (ViewMatchers.Visibility. VISIBLE ) allOf( withId (R.id. count ), hasSibling (withText (R.string. summary_header ) ViewMatchers
9. • Perform(click(.....)) • Perform(ScrollTo(....)) • Perform(replaceText(....)) • Perform(swipeRight(....)) ViewActions
10. check(matches(withText(quantity))) check(matches(withChild(withText(message)))) check(matches(hasDescendant(withText(heading)))) check(doesNotExist()) check(matches(isDisplayed())) ViewAssertions
11. atPosition() - onData(...).atPosition(2).perform(click()); inRoot() - toast message checking - prompts etc... onChildView() Data Interaction
12. • GetChildCount() • SetMobileData() • ScanActions() • SetProfile() Extensible & Customizable
13. • Webview • StubTesting using Intent and ServiceTestRule • Extend to test performance, memory leakage • Pretty reports Others
14. • API is small, predictable and easy to learn • Support from API level 8 (Froyo) • Light weight, Fast and Reliable test • Rich failure information and customizable failure handling • Automatic synchronization of test actions loopmainthreaduntilidle • Can use UI automator methods • Runs on actual device or emulator, mimics user WHY
15. • Application push notifications • Sync Test • Navigating from another app to your app • Extending test to other OS WHAT NOT
