Encountering the “Instrumentation run failed due to ‘Process crashed.'” error can be a frustrating experience for developers running Android Instrumented tests. This guide aims to provide a structured approach to diagnose and resolve this issue effectively.
Understanding the Error
This error typically occurs when there is a configuration issue in the testing setup or a mismatch in dependencies. Below, we outline several common solutions to address this problem.
Solution 1: Update Test Instrumentation Runner
If you have recently updated to AndroidX, it is crucial to update your build.gradle file accordingly. The previous configuration:
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"should be updated to:
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"This change ensures that your project uses the correct test runner compatible with AndroidX.
Solution 2: Check Logcat for Detailed Errors
In many cases, the Android test console may not provide detailed error messages. It is advisable to check Logcat for more comprehensive error details. For instance, missing configurations such as the AdMob app_id in AndroidManifest.xml can cause the test to crash.
Solution 3: Verify Dependency Versions
Ensuring that all dependencies are compatible with each other is another critical step. Consider updating your dependencies to the latest versions:
androidTestImplementation "androidx.test.espresso:espresso-core:3.3.0"
androidTestImplementation "androidx.test:runner:1.3.0"
androidTestImplementation "androidx.test:core:1.3.0"
androidTestImplementation "androidx.test.ext:junit:1.1.2"
androidTestImplementation "androidx.test:rules:1.3.0"Consistency in dependency versions helps avoid conflicts that may lead to crashes.
Solution 4: Adjust Build Configuration
Sometimes, certain build configurations such as minifyEnabled and shrinkResources can cause issues. Consider commenting out these lines in your build.gradle file:
buildTypes {
debug {
debuggable true
//minifyEnabled true
//shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}This adjustment can resolve issues related to resource shrinking and code minification.
Solution 5: Downgrade JUnit Version
In some cases, upgrading the JUnit version can cause compatibility issues. If you recently upgraded JUnit, try downgrading to a previous version:
androidTestImplementation 'junit:junit:4.12'This change has resolved the error for some developers.
Conclusion
By following these steps, you can effectively diagnose and resolve the “Instrumentation run failed due to ‘Process crashed.'” error in your Android tests. Each solution addresses a specific aspect of the testing setup, from updating configurations to verifying dependencies.
