Class DexOpener

java.lang.Object

com.github.tmurakami.dexopener.DexOpener

public final class DexOpener
extends java.lang.Object

This is a utility that provides the ability to mock your final classes. To use this, first add an AndroidJUnitRunner subclass into your app's androidTest directory.

 // Specify your root package as `package` statement.
 // The final classes you can mock are only in the package and its subpackages.
 package your.root.pkg;

 public class YourAndroidJUnitRunner extends AndroidJUnitRunner {
     @Override
     public Application newApplication(ClassLoader cl, String className, Context context)
             throws ClassNotFoundException, IllegalAccessException, InstantiationException {
         DexOpener.install(this); // Call me first!
         return super.newApplication(cl, className, context);
     }
 }
 

Then specify your AndroidJUnitRunner as the default test instrumentation runner in your app's build.gradle.

 android {
     defaultConfig {
         minSdkVersion 16 // 16 or higher
         testInstrumentationRunner 'your.root.pkg.YourAndroidJUnitRunner'
     }
 }
