Can't Select Test Class In Edit Configuration

I have created an Espresso/UIAutomator unit test. However, when I try to run it, Android Studio won't recognize it. The button to select TestLogin.java is greyed out. I'm using An

Solution 1:

Add one more package with name test like that: com.greenrobot.yesorno.test. Then put TestLogin test inside it. This should solve your problem.

ALSO: ActivityInstrumentationTestCase2 is deprecated and can't be used together with ActivityTestRule. Leave only ActivityTestRule and remove extends part and constructor. I'd also suggest to add setUp() method with @Before annotation and instantiate mDevice there, so it will be available for each test you'll have in test class.

UPDATE: also remove this, sync and clean:

 androidTest {
     java.srcDirs = ['androidTest/java']
 }

Solution 2:

I hired a developer on Upwork to look into this for me. The main problem was the my androidTest src directive was missing a 'src'

    androidTest {
        java.srcDirs = ['src/androidTest/java']
    }

My build.gradle:

    buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

I spent 10 minutes trying to get TestLogin to format as code and it wouldn't work so I created a pastebin. http://pastebin.com/9W3pT4rH Stackoverflow, you should allow me to select files, and then display them as code.
