Question

以下是build.gradle文件中的配置：

testCompile 'junit:junit:4.12'
androidTestCompile('com.android.support:multidex-instrumentation:1.0.1') {
    exclude group: 'com.android.support', module: 'multidex'
}
androidTestCompile 'com.android.support:support-annotations:24.2.1'
androidTestCompile 'com.android.support.test:runner:0.5'
androidTestCompile 'com.android.support.test:rules:0.5'
androidTestCompile 'com.jayway.android.robotium:robotium-solo:5.6.3'
androidTestCompile 'com.squareup.okhttp3:mockwebserver:3.4.1'
androidTestCompile 'com.google.truth:truth:0.30'
androidTestCompile 'com.github.ignaciotcrespo:frutilla:0.7.1'
androidTestCompile 'org.mockito:mockito-core:2.2.9'
androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.2'
androidTestCompile 'com.squareup.okhttp3:okhttp-testing-support:3.4.1'

开始all my tests，或只是one of them，例如：

@Test
public void test_Parse_JSONRepo_ParsesRepoDTO() throws IOException {
    ObjectMapper loJSONMapper = new ObjectMapper();
    String lsRepoData = mLocalifyClient.localify().loadRawFile(R.raw.repo_octocat);

    DTORepo loRepoDTO = loJSONMapper.readValue(lsRepoData, DTORepo.class);

    assertThat(loRepoDTO).isNotNull();
    assertThat(loRepoDTO.name).isEqualTo("git-consortium");
}

我在Android Studio中收到以下消息：

Started running tests
Test running failed: Instrumentation run failed due to 'java.lang.AbstractMethodError'
Empty test suite.

测试套件输出总是非常简洁。在这种情况下，最好检查“Android Monitor”logcaat输出是什么。

答案就在那里：

java.lang.AbstractMethodError: abstract method "org.mockito.plugins.MockMaker$TypeMockability org.mockito.plugins.MockMaker.isTypeMockable(java.lang.Class)"

这是Mockito版本高于2.0.17-beta而不与dexmaker-mockito合作的已知错误。关于它的更多信息here。

解决方案只是使用不同版本的Mockito：

androidTestCompile 'org.mockito:mockito-core:2.0.17-beta'
