"RobolectricTestRunner.class" not recognized in Android Studio

I'm trying to use Robolectric to run unit tests but the Android Studio is not recognizing the class on:

@RunWith(RobolectricTestRunner.class)

Details:

classpath 'com.android.tools.build:gradle:3.0.0'

And I'm importing dependency:

testImplementation "org.robolectric:robolectric:3.5.1"

And:

android {
    testOptions {
        unitTests {
            includeAndroidResources = true
        }
    }
}

It simply does not appear option to import the class. Should I add any more dependencies I'm forgetting?

Error:

 error: package org.robolectric does not exist
 error: package org.robolectric does not exist
 error: package org.robolectric.shadows does not exist
 error: cannot find symbol class RobolectricTestRunner
 error: cannot find symbol variable Robolectric
 error: cannot find symbol variable ShadowApplication

can you try with testImplementation instead of testCompile. It's depracated now with gradle version 4 – Autogenous 15/11, 2017 at 10:0

@Autogenous the error is the same with androidTestImplementation and not recognizing with testImplementation. I use the: androidTestImplementation 'com.android.support.test:runner:1.0.1' and it works correctly on the same project, just the roboletric that is not working. – Grossularite 16/11, 2017 at 11:1

Robolectric is always test and not androidTest dependency – Woodring 20/11, 2017 at 11:15

I solved the issue just by putting the test class inside the src \ test folder instead of putting it in thesrc \ androidTest folder

dude... you save life – Azotobacter 1/2, 2018 at 21:51

@JacktheRipper LOL, glad to have helped!! – Grossularite 5/2, 2018 at 10:11

Very nice. Thanks a lot. But why does that happen? Is there a way to configure it to accept src \ androidTest? – Vareck 8/6, 2018 at 12:7

Nice!! It helps!! – Paraffinic 3/8, 2018 at 13:37

It took me 1 hour to solve the issue until I found your answer, thank you. – Anubis 19/2, 2019 at 6:31

Since this helped me as well - you can get it to wotk in androidTest by using androidTestImplementation instead of testImplementation in gradle. – Miniature 15/11, 2021 at 14:14

Usually there will be 2 kinds of tests 'androidTest' and 'test'.

If you add dependency like androidTestImplementation 'org.robolectric:robolectric:4.3.1', Robolectric package will only be imported in 'androidTest' classes.

If you add dependency like testImplementation 'org.robolectric:robolectric:4.3.1', they can only be imported in 'test' classes.

I just added both, androidTestImplementation and testImplementation – Homologous 15/1, 2021 at 16:16

This is the right answer I must say – Luca 18/2 at 14:10

I followed most of the recommendations without any luck.
I then changed a dot (.) to double-colon (::)

was ...

@RunWith(RobolectricTestRunner.class)

changed to ...

@RunWith(RobolectricTestRunner::class)

RobolectricGradleTestRunner is deprecated since version 3 of Robolectric. Just use @RunWith(RobolectricTestRunner.class) Take a look at official documentation.

I followed the official documentation, but the error continued ... Any other suggestions? Some more dependence, I don't know ... – Grossularite 14/11, 2017 at 16:26

If your test file is written in kotlin then use @RunWith(RobolectricTestRunner::class)
