将Espresso升级到版本2后，我的单元测试都不会在棒棒糖前设备上运行。请参见下面的曲目：

堆栈跟踪同样无益

有什么奇怪的是它在5.0设备上工作没问题。

当你的应用程序和测试应用程序具有相同的依赖关系时，较旧的设备在运行测试时遇到问题。

要解决此问题，您必须确定哪些依赖项会导致问题。

在我的情况下，Dagger和Espresso都取决于javax.inject，这就是＆＃34;修复＆＃34;：

androidTestCompile('com.android.support.test.espresso:espresso-core:2.0') {
    exclude group: 'javax.inject'
}

如果您包含更多或更奇怪的依赖项，您可以查看this build.gradle。

使用espresso-contrib时，您可能需要这样做：

androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.0') {
    exclude group: 'javax.inject'
    exclude group: 'com.android.support'
}

答案 1 :(得分：5)

当相同的依赖项被包含多次或使用不同的版本时，通常会出现问题。

我有一个工作项目使用espresso2和multidex for api level 14 +。

检查this SO question。接受的答案帮了很多忙。

大多数情况下，使用./gradlew -q：myproject：dependencies，您可以检查重复的依赖关系或不同版本的相同依赖关系不止一次。

这是我的espresso依赖项的一个例子，但我不得不改变并排除许多：

....
//Espresso 2
androidTestCompile('com.android.support.test.espresso:espresso-core:2.0') { 
    exclude group: 'com.google.guava'
    exclude module: 'espresso-idling-resource'
}
androidTestCompile('com.android.support.test:testing-support-lib:0.1') { 
    exclude group: 'com.google.guava'
    exclude module: 'espresso-idling-resource'
}
testingCompile ('com.android.support.test.espresso:espresso-contrib:2.0') {
    exclude group: 'com.google.guava'
    exclude group: 'com.android.support', module: 'support-v4'
}
// Need to exclude this when running test
androidTestCompile('com.android.support:multidex-instrumentation:1.0.1') {
    exclude group: 'com.android.support', module: 'multidex' 
}
....

./ gradlew -q：myproject：dependencies 将为每个变体+风味组合提供如下输出：

答案 2 :(得分：5)

我在测试中使用RecyclerView时遇到了类似的问题，通过在build.gradle添加以下代码解决了这个问题：

configurations {
    androidTestCompile.exclude group: 'com.android.support', module: 'recyclerview-v7'
}

此外，您还可以尝试添加以下排除：

configurations {
    androidTestCompile.exclude group: 'com.android.support', module: 'support-v4'
}

所以，configurations build.gradle看起来像那样：

configurations {
    androidTestCompile.exclude group: 'com.android.support', module: 'support-v4'
    androidTestCompile.exclude group: 'com.android.support', module: 'recyclerview-v7'
}

这解决了我遇到的两个问题：java.lang.IllegalAccessError: Class ref in pre-verified class resolved to unexpected implementation和java.lang.NoClassDefFoundError。之后，我能够对棒棒糖前设备进行测试。
