1.在build.gradle中添加依赖:
dependencies {
androidTestCompile 'com.android.support.test:runner:0.2'
androidTestCompile 'com.android.support.test:rules:0.2'
androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.0'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.1'
}
2.然后添加
defaultConfig {
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
3.添加完成后，总会碰到
Error:Conflict with dependency 'com.android.support:support-annotations' in project ':app'. Resolved versions for app (25.2.0) and test app (23.2.1) differ
这样的版本冲突问题，很头疼，解决办法，在android{}中添加：
configurations.all {
resolutionStrategy.force"com.android.support:support-annotations:23.2.1"
}
之后才能解决~目前遇到的就是这样的问题了，如果以后还有就继续补充~
