If you’re diving into the world of Android development, capturing the visual fidelity of your app can be a daunting task. However, the Shot tool simplifies this process. This blog will guide you step-by-step on how to set up and utilize Shot for screenshot testing in your Android projects.

What is Shot?

Shot is a Gradle plugin designed for Android developers to easily write screenshot tests for their applications. It’s a powerful tool that provides an interface named ScreenshotTest and an efficient test runner ShotTestRunner that streamline the testing process.

Getting Started with Shot

Before you can begin capturing those all-important screenshots, you’ll need to set up Shot in your project. Here’s how:

• Open your build.gradle file and add the following dependency:

buildscript {
        ...
        dependencies {
            ...
            classpath 'com.karumi:shot:LATEST_RELEASE'
        }
    }

• Apply the plugin in your app module’s build.gradle file:

apply plugin: 'shot'

• Set the instrumentation test runner in the same build.gradle file:

android {
        ...
        defaultConfig {
            ...
            testInstrumentationRunner 'com.karumi.shot.ShotTestRunner'
        }
    }

Writing Your First Screenshot Test

Now that Shot is set up, let’s write a test! Think of it like snapping a picture with a camera. You want to ensure the picture turns out just right every time. Here’s how to do it:

class GreetingScreenshotTest : ScreenshotTest {
    @Test
    fun rendersGreetingMessageForTheSpecifiedPerson() {
        composeRule.setContent { Greeting(greeting) }
        compareScreenshot(composeRule)
    }
}

This code snippet sets up a test for a greeting message displayed in Jetpack Compose.

Recording and Verifying Screenshots

Once your tests are written, it’s time to record the screenshots and verify that everything looks as expected.

• To record your screenshots, run:

./gradlew executeScreenshotTests -Precord

• To verify the tests, simply execute:

./gradlew executeScreenshotTests

How to Deal with Errors

Sometimes, things may not go as planned. If Shot encounters any issues, it will generate a detailed error report. Here are some troubleshooting tips:

• Ensure your emulator is configured with gpu mode swiftshader_indirect to prevent rendering issues.
• Double-check your Gradle configurations.
• If you’re uncertain about configuration settings, it may be helpful to refer back to the Jetpack Compose documentation.
• Whenever you face any persistent issues, don’t hesitate to ask for assistance on community forums or revert to the guidelines provided in this post.
