Question

我想在Android应用中测试2个静态方法。所以我使用PowerMock。

我写了2个测试。一个单元测试和一个仪器化单元测试。

我的android build.gradle：

dependencies {
    androidTestCompile "org.mockito:mockito-android:2.7.21"
    androidTestCompile "org.powermock:powermock-api-mockito:1.6.6"
    androidTestCompile 'org.powermock:powermock-module-junit4:1.6.6'
    testCompile 'junit:junit:4.12'
    testCompile 'org.powermock:powermock-api-mockito:1.6.6'
    testCompile 'org.powermock:powermock-module-junit4:1.6.6'
}

单元测试位于文件夹中： app / src / test / java / com / mycompany / StringUtilTest.java

这里代码：

    @RunWith(PowerMockRunner.class)
    @PrepareForTest(StringUtil.class)
    public class StringUtilTest {

        @Test
        public void isCorrectEmailStub() {
            // mock all the static methods in a class called "StringUtil"
            mockStatic(StringUtil.class);
            String INCORRECT_EMAIL_TO_CHECK = "incorrect_email_some.com";                
   when(StringUtil.isCorrectEmail(INCORRECT_EMAIL_TO_CHECK)).thenReturn(true);
            assertThat(StringUtil.isCorrectEmail(INCORRECT_EMAIL_TO_CHECK), is(true));
        }
    }

它工作正常。行。

检测单元测试位于文件夹中： app / src / androidTest / java / com / mycompany / StringUtilInstrumentedTest.java

这里代码：

    @RunWith(PowerMockRunner.class)
@PrepareForTest(StringUtil.class)
public class StringUtilInstrumentedTest {
    private static String TAG;
    private Context context;

    @Before
    public void init() {
        TAG = StringUtilInstrumentedTest.class.getName();
        context = InstrumentationRegistry.getTargetContext();
    }

    @Test
    public void decliningAge() {
        // mock all the static methods in a class called "StringUtil"
        mockStatic(StringUtil.class);
        // use Mockito to set up your expectation
        String expected = "first";
        when(StringUtil.decliningAge(context, 1)).thenReturn(expected);
        assertThat(StringUtil.decliningAge(context, 1), is(expected));
    }
}

但是当我运行此测试时，我收到错误：

java.lang.ClassNotFoundException: com.mycompany.StringUtilInstrumentedTest
at java.lang.Class.classForName(Native Method)
at java.lang.Class.forName(Class.java:324)
at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1879)

Android：PowerMock在“test”文件夹中工作但在“androidTest”文件夹中不起作用
