Android的 - 空測試套件（AbstractMethodError）

Question

這裏是在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' 

開始all my tests，或者乾脆one of them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"); 
} 

我拿到Android的以下信息工作室：

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

Answer 1

te st suite的輸出總是非常簡潔。在這種情況下，最好檢查一下「Android Monitor」logcaat輸出是什麼。

答案是有：

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

這與版本的Mockito比2.0.17-beta更高的一個已知的bug不dexmaker-mockito合作。更多關於它here。

的解決方案只是使用的Mockito不同的版本：

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