我继承了一个由主应用程序和一个Library组成的Android项目。我的目标是测试整个项目,所以我从库开始:首先我使用JUnit测试一些类/方法,编写我的库项目的测试undeer app / src / test / java(单元测试),并生成一个Android Studio的代码覆盖率报告。当我找到一个使用Parcel的Class(来自Android Framework)时,问题就来了,所以这一次我不得不在Library项目中设置一个已测试的测试(app / src / androidTest / java)。
当我尝试运行仪器测试并插入Android设备时,收到以下消息:
Started running tests
Test running failed: Instrumentation run failed due to 'java.lang.ClassNotFoundException'
Empty test suite.
当我的测试类中有多个@Test方法时,我不明白为什么会“清空测试套件”。我是否已设置Gradle如何在测试过程中链接主应用程序和库,或者也许我必须将所有测试都移至主应用程序中?!
这是我对“图书馆”模块的认可:

我遇到了同样的问题,不是Parcel
,而是其他类似Context
的android组件。
对于此问题,
空测试套件
您在仪器化的测试课程中,必须加注 @RunWith(AndroidJUnit4.class)
。
最初,我确实在app
中编写了Instrumented测试。但是在InstrumentationTests
中写入库的app
的问题是,您将无法获得library
的覆盖率报告。
因此,我将InstrumentedTests
移回了library/androidTest
文件夹。经过大量研究,我找到了一种解决方案,可获取library
请按照您图书馆的build.gradle
文件中的内容进行操作
添加apply plugin: 'jacoco'
启用以下测试范围
android {
buildTypes {
debug {
testCoverageEnabled true
}
}
...
}
添加以下依赖项
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test:rules:1.0.2'
我相信,对于您项目中的任何模块,如果您的模块/库中有androidTests
,将有一个名为combinedTestReportDebug
的默认任务。
您可以在Android Studio右上角垂直栏中的Gradle
菜单中找到它。
Gradle menu > :your-library > Tasks > reporting > combinedTestReportDebug
或
从您的Terminal
> ./gradlew clean combinedTestReportDebug -p :your-library
中运行此命令
测试完成后,您可以在以下位置找到覆盖率或失败的测试
对于失败的测试: your-library/build/reports/androidTests/connected/index.html
有关覆盖率报告: your-library/build/reports/coverage/debug/index.html
我希望这会有所帮助。
对不起,我忘记提及下面的步骤了,因为如果没有combinedTestReportDebug
,将不可见。感谢@nicoabie。
在项目的build.gradle
文件中,执行以下操作以使combinedTestReportDebug
任务在您的库gradle任务中可见。
buildscript {
repositories {
jcenter()
}
dependencies {
...
classpath 'com.vanniktech:gradle-android-junit-jacoco-plugin:0.13.0'
...
}
}
...
apply plugin: 'com.vanniktech.android.junit.jacoco'
