Github code https://github.com/chiuki/android-test-demo
Override dagger Module by androidTesting. Demo App in folder android-test-demo-master

• override TestRunner in app/build.gradle

defaultConfig {
applicationId 'com.sqisland.android.test_demo'
minSdkVersion 8
targetSdkVersion 23
versionCode 1
versionName '1.0.0'

testInstrumentationRunner 'com.sqisland.android.test_demo.MockTestRunner'

}
In MockTestRunner we call MockDemoApplication.java

• app/buld.gradle dependency androidTestAnnotationProcessor "com.google.dagger:dagger-compiler:2.11" for build components and modules in TestActivity for DaggerMainActivityTest_TestComponent.builder().build(); in MockDemoApplication.java

• edit Configuration MainActivityTest.java to change TestRunner to MockTestRunner

• best approach to create dagger2 component is create classic components without dependent component and subcomponent . It's easy to override classic component in MockApplication.java and ActivityTest.java without change app code only in testcode.

• is better provide dependencies in Module.java instead of base injection in class constructors because of easy override provided dependency in androidTestActivity

• ApplicationModule.java included to ClockModule.java

`@Module(includes = {ApplicationModule.class} )
public class ClockModule {

@provides
@singleton
Clock provideClock() {
return new Clock();
}

@provides
@singleton
SharedPreferences providesSharedPreferences(Application application) {
return PreferenceManager.getDefaultSharedPreferences(application);
}

}`

ADD Lambda Expression Support

• add to project/build.gradle
  dependencies { classpath 'com.android.tools.build:gradle:2.3.3' classpath 'me.tatarka:gradle-retrolambda:3.5.0' }

• add to app/build.gradle

`apply plugin: 'com.android.application'
apply plugin: 'me.tatarka.retrolambda'

android {
compileSdkVersion 23
buildToolsVersion '25.0.2'

compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
`

Add Realm

• add to app/build.gradle

`dependencies {

// Realm
compile 'io.realm:realm-android:0.82.1'`

Add RxJava and RxAndroid

• add to app/build.gradle

`dependencies {

//rxjava
compile 'io.reactivex.rxjava2:rxjava:2.0.1'
compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
compile 'io.reactivex:rxandroid:1.2.0'
`

• because of Duplicate files copied in APK META-INF/rxjava.properties add to app/build.gradle

packagingOptions { //duplicate files copied in apk meta-inf/rxjava exclude 'META-INF/rxjava.properties' }

• i have created one MockTestRunner.java that call one DemoApplication.java
• in DemoApplication.java are separated createcomponent method for each component
• the testactivity override createcomponent method in DemoApplication.java with appropriated module
• overriding modules work ok in activity and fragment
• attention, what component you inject in activity that component you have to override in tastactivity
