When I'm adding the
androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.1'
in the gradle and run an Espresso test, I get the following error:

Tests ran to completion.
and the tests aren't running. I suspect is a gradle problem so here is my app gradle file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
dataBinding {
enabled = true
}
defaultConfig {
applicationId "databinding.com.masterdetails"
minSdkVersion 18
targetSdkVersion 23
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:support-v4:23.1.1'
compile 'com.android.support:recyclerview-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
androidTestCompile 'com.android.support:support-annotations:23.1.1'
// Android JUnit Runner
androidTestCompile 'com.android.support.test:runner:0.4.1'
// JUnit4 Rules
androidTestCompile 'com.android.support.test:rules:0.4.1'
// Espresso core
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
// Espresso-contrib for DatePicker, RecyclerView, Drawer actions, Accessibility checks, CountingIdlingResource
androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.1'
androidTestCompile 'com.android.support.test.espresso:espresso-idling-resource:2.2.1'
}
I need to add
androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.1'
so I can test with RecyclerView.
回答1:
Please check my dependendecies, especially espresso ones.
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
androidTestCompile "com.android.support:support-annotations:$ASVersion"
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.1'
androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2.1') {
exclude group: 'com.android.support', module: 'appcompat'
exclude group: 'com.android.support', module: 'support-v4'
exclude module: 'recyclerview-v7'
}
androidTestCompile 'com.android.support.test:runner:0.4.1'
compile 'com.squareup.retrofit:retrofit:1.9.0'
compile "com.android.support:appcompat-v7:$ASVersion"
compile "com.android.support:support-v4:$ASVersion"
compile "com.android.support:design:$ASVersion"
}
where def ASVersion = '23.1.1'
Maybe you missed something. Mine already working
Hope it help
回答2:
Seems that you include RecyclerView component twice: here - compile 'com.android.support:recyclerview-v7:23.1.1' and here androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.1'. Add below code in your build.gradle after dependencies section and try again:
configurations {
androidTestCompile.exclude group: 'com.android.support', module: 'recyclerview-v7'
}
