我在模拟静态方法进行仪器测试(Espresso
)时遇到了困难。 对于模拟对象,我使用Mockito
。 但是,由于Mockito
无法模拟静态方法,因此我在其上使用Powermock
。 这对于在JVM机器上运行的测试很好用,但对于UI测试,这种组合效果不佳。 我已经为仪器测试声明了以下依赖项。
androidTestCompile 'org.mockito:mockito-core:1.10.19'
androidTestCompile 'org.powermock:powermock-api-mockito:1.6.5'
androidTestCompile 'org.powermock:powermock-module-junit4:1.6.5'
androidTestCompile 'com.google.dexmaker:dexmaker:1.2'
androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.2'
androidTestCompile 'com.android.support.test:runner:0.5'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
我写了一个如下的样例测试。
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(AndroidJUnit4.class)
public class SampleTest {
@Test
public void test(){
//Test Code.
}
}
代码编译成功,但在运行时出现以下异常信息。
java.lang.IllegalStateException: Extension API internal error: org.powermock.api.extension.proxyframework.ProxyFrameworkImpl could not be located in classpath.

还有什么我没想到的吗?在Espresso测试中,是否有任何方法可以模拟静态方法?
