在我的测试中,我如何模拟我写的课程?
这是我的测试代码:
import android.support.test.runner.AndroidJUnit4;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;
import static org.mockito.Mockito.never;
import static org.mockito.Mockito.verify;
@RunWith(AndroidJUnit4.class)
public class SampleTest {
@Mock
Sample mySample;
@Before
public void setup() {
MockitoAnnotations.initMocks(this);
}
@Test
public void shouldMockSample() {
verify(mySample, never()).neverCallMe();
}
}
示例只是一个虚拟类。
public class Sample {
public void neverCallMe() {}
}
如何摆脱此错误?

从版本2.6。+开始,Mockito添加了一个适用于Android的新工件,无需任何其他依赖(即不再需要导入DexMaker)。 (Reference)
只需使用org.mockito:mockito-android
作为已检测单元测试的依赖项(androidTest
)。您仍然可以使用通常的org.mockito:mockito-core
进行本地单元测试。
示例:
dependencies {
...
testCompile 'org.mockito:mockito-core:2.7.15'
androidTestCompile 'org.mockito:mockito-android:2.7.15'
...
}

默认情况下,Mockito使用CGLib或ByteBuddy,两者都生成.class
个文件。您已在Android设备或模拟器上运行,因此.class
文件无法提供帮助;你需要.dex
格式。
调整您的依赖关系以使用DexMaker,这将覆盖Mockito的默认设置并允许在Android环境中进行模拟。
