配置同时使用PowerMock和Robolectric对Android进行单元测试

Robolectric官网上给了一个配置教程，但是我使用它的方法进行配置，发现使用Mockito.spy函数的时候会出现Exception。

后来在PowerMock官网上找到了另外一个教程，里面说使用PowerMockRule是不靠谱的，要使用PowerMock 1.6.0引入的新的@PowerMockRunnerDelegate annotation来进行配置

具体配置文件如下：

module里面的build.gradle添加依赖:

dependencies {
    ......

    testCompile "org.robolectric:robolectric:3.0"
    testCompile ‘org.mockito:mockito-core:1.10.19‘
    testCompile ‘junit:junit:4.12‘
    testCompile "org.powermock:powermock-module-junit4:1.6.4"
    testCompile "org.powermock:powermock-module-junit4-rule:1.6.4"
    testCompile "org.powermock:powermock-api-mockito:1.6.4"
    testCompile "org.powermock:powermock-classloading-xstream:1.6.4"
}

对下面的 RobolectricTest 基类进行继承，就可以正常使用PowerMock和Robolectric进行测试了

import org.junit.runner.RunWith;
import org.powermock.core.classloader.annotations.PowerMockIgnore;
import org.powermock.modules.junit4.PowerMockRunner;
import org.powermock.modules.junit4.PowerMockRunnerDelegate;
import org.robolectric.RobolectricGradleTestRunner;
import org.robolectric.annotation.Config;

/**
 * Base class extended by every Robolectric test in this project.
 */
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class,
        sdk = 21)
@PowerMockIgnore({"org.mockito.*", "org.robolectric.*", "android.*"})
public abstract class RobolectricTest {

}
