You need to add following to your build.gradle file for instrumentation test:

androidTestApt 'com.google.dagger:dagger-compiler:'

or for JUnit test:

testApt 'com.google.dagger:dagger-compiler:'

This is required to generate Dagger code for your test components.

EDIT:

If you are using jack tool chain then add following for android test:

androidTestAnnotationProcessor 'com.google.dagger:dagger-compiler:'

for JUnit tests:

testAnnotationProcessor 'com.google.dagger:dagger-compiler:'

EDIT:

In case you are using kotlin-kapt for Kotlin code use following:

kaptAndroidTest 'com.google.dagger:dagger-compiler:'

or for JUnit test:

kaptTest 'com.google.dagger:dagger-compiler:'
