Android Espresso Issue - Dependency conflict

Question

I\'m trying to integrate espresso into my application for ui testing. Here are my dependencies in Gradle

dependencies {
    compile fileTree(dir: \'libs\', inclu         


        

Answer 1

New version of espresso-contrib 2.2.2 library has now dependency on com.android.support:appcompat-v7:23.1.1 resulting into conflict when using different version of appcompat-v7 in our compile time dependency like below:

dependencies {
     compile fileTree(dir: 'libs', include: ['*.jar'])
     testCompile 'junit:junit:4.12'
     compile 'com.android.support:appcompat-v7:23.4.0'

     androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.2'
}

To avoid conflict when we exclude appcompat-v7 dependency from espresso-contrib like below it breaks again due to some value dependencies on design support lib.

androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.2.2'){
    exclude module: 'support-annotations'
    exclude module: 'support-v4'
    exclude module: 'support-v13'
    exclude module: 'recyclerview-v7'
    exclude module: 'appcompat-v7'
}

Error:

Error:(69) Error retrieving parent for item: No resource found that matches the given name 'TextAppearance.AppCompat.Display1'.

So, the solution to above problem is to exclude 'design-support' lib depedency from espresso-contrib like below:

androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.2.2'){
    exclude module: 'support-annotations'
    exclude module: 'support-v4'
    exclude module: 'support-v13'
    exclude module: 'recyclerview-v7'
    exclude module: 'design'
}

That solves the conflict problem!
