Android Espresso testing 'Cannot resolve symbol 'InstrumentationRegistry''

Question

I'm trying to import

 import android.support.test.InstrumentationRegistry;

my build.gradle file

androidTestCompile 'com.android.support.test:testing-support-lib:0.1'
androidTestCompile 'com.android.support.test:runner:0.2'
androidTestCompile 'com.android.support.test:rules:0.2'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'

in default config:

defaultConfig {
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

Is there a library I'm missing here? I'm trying to import InstrumentationRegistry but it doesn't recognise it!

please visit http://stackoverflow.com/questions/30373074/sources-of-testing-support-library-in-android-studio . Hope this helps . — IntelliJ Amiya, Mar 28 '16 at 12:39

Check what kind of test do you use.

InstrumentationRegistry used for Instrumented tests that use emulator or device and they are placed in src/androidTest and use config androidTestCompile.
If you use Local unit tests for JVM from folder src/test you should use config testCompile

testImplementation 'com.android.support.test:runner:1.0.2'

After that you can import InstrumentationRegistry, but you will get other errors at run-time.

Agree, great answer! God bless you!) I've changed androidTestCompile to testCompile and InstrumentationRegistry resolved, – Kiryl Ivanou Nov 10 '17 at 14:33

try

compile 'com.android.support.test:runner:0.2'

instead of

testCompile 'com.android.support.test:runner:0.2'

Use `implementation` as `compile` is obsolete – Spikatrix Jan 15 '19 at 09:34

it seems, com.android.support.test had been recently excluded from some other package (no clue which one), which also resulted in android.support.test.InstrumentationRegistryto be unknown; not excluding it from com.android.support.test:runner fixed the issue for me.

androidTestImplementation ("com.android.support.test:runner:1.0.2") {
    // exclude group: "com.android.support.test"
    exclude group: "com.android.support"
}

basically, androidTestImplementation needs to contain com.android.support.test once.

Another alternative - you can also add androidx.test:monitor dependency where the class InstrumentedRegistry is.

androidTestImplementation 'androidx.test:monitor:x.y.z'
