7. Calabash
Another open-source framework for testing mobile apps that works with both iOS and Android is called Calabash. It is based on the behavior-driven development (BDD) tool Cucumber. Consequently, for testers who would prefer to write tests in natural language, Calabash is the most suitable iOS application.
Types of Tests in Android Automation
Various types of tests can be automated for Android apps. Each type focuses on different aspects of the application and helps ensure overall quality.
Unit Testing
Unit testing is defined as a system of testing an individual component or unit of the app—functions, methods, etc. These tests are commonly used for different forms of automation, like Test-Driven Development, using frameworks such as JUnit. They are quick to perform, and the problems detected are often early in the development process.
UI Testing
Usability (UI) testing verifies how a user communicates with an application. It allows for numerous badly and well-designed UI elements including buttons, menus, and others interacting exactly as required. Automated testing can be done with the help of frameworks, namely Espresso and UIAutomator.
Integration Testing
Integration testing focuses on how various app components work together. It checks the interaction between different modules and services in the app. Integration tests can be automated using tools like Appium.
End-to-End (E2E) Testing
End-to-end testing checks whether the whole application works from beginning to end. It helps make all app features functional and operative on different devices and operating systems. The most commonly used type of testing with the help of Appium is E2E testing.
Performance Testing
Performance testing checks how the app performs under different conditions, such as varying loads, memory usage, or CPU usage. Tools like JMeter or Android Profiler can be used for performance testing.
Regression Testing
Regression testing makes sure that any updates to the program don’t interfere with already-existing features. Automated regression tests can be executed repeatedly and are essential for maintaining stability over multiple app updates.

Setting Up Your Android Testing Environment
To automate Android tests, you need to prepare several things before you start the process. This usually comprises obtaining the right tools, the Android SDK, and your test framework.
1. Install Android Studio
For Android apps, the official Integrated Development Environment is called Android Studio. It includes all the required tools for generating and executing tests for Android applications. You can download it from the official Android Studio website.
2. Install Android SDK
The Android SDK incorporates the basic working libraries, development and testing tools, and APIs for Android. It can be downloaded from the Android Studio and will be set up for use depending on the settings made during the download.
3. Choose Your Test Framework
Depending on the project’s requirements, choose the appropriate test framework. For UI testing, consider using Espresso, while for cross-platform tests, Appium is a good choice.
4. Set Up Your Testing Device
Android installed on an emulator or on a physical device can be used for testing. An emulator can also be created in Android Studio, where you can perform your tests on Android devices with screens and OSs of various sizes.
5. Configure Your Test Project
After setting up the environment, create a new test project in Android Studio. You can include dependencies for the chosen testing frameworks in your project’s build.gradle file.
Writing Your First Automated Test
Now that your environment is set, it’s time to write your first automated. Let’s walk through a simple test using Espresso.
a. Create a Test Class
In Android Studio, navigate to the src/test/java directory, create a new Java class, and name it MainActivityTest.java.
b. Write the Test Script
Here’s an example test that checks if a button is displayed on the screen and clicks it:
@RunWith(AndroidJUnit4.class)
public class MainActivityTest {
@Test
public void testButtonClick() {
// Launch the app
on view(withId(R.id.button)).check(matches(isDisplayed()));
// Perform click action
onView(withId(R.id.button)).perform(click());
// Assert that the expected result occurs
onView(withId(R.id.textView)).check(matches(withText(“Button clicked!”)));
}
}
c. Run the Test
Once your test is written, run it on an emulator or physical device directly from Android Studio. The test will perform the specified actions and verify the expected outcomes.
