我继承了一个由主应用程序和库组成的Android项目。我的目标是测试整个项目,所以我从Library开始:首先我使用JUnit测试一些类/方法,编写我的Library项目的测试Under app/src/test/java(单元测试(,并由Android Studio生成代码覆盖率报告。当我找到一个使用Parcel(来自Android Framework(的类时,问题就来了,所以这次我不得不在Library项目中设置一个插入测试(app/src/androidTest/java(。
当我尝试运行仪器测试,插入安卓设备时,我得到了这样的消息:
Started running tests
Test running failed: Instrumentation run failed due to 'java.lang.ClassNotFoundException'
Empty test suite.
我不明白为什么"空测试套件",而我的测试类中有几个@test方法。我必须设置Gradle如何在测试期间链接主应用程序和库吗?也许我必须在主应用程序中移动所有测试?!
这是我对图书馆模块的成绩:

感谢关注!
我遇到了同样的问题,不是Parcel
,而是Context
等其他android组件。
对于这个问题,
空的测试套件
中插入指令的测试类必须用@RunWith(AndroidJUnit4.class)
进行注释。
关于图书馆的代码覆盖范围
最初,我确实用app
编写了仪器测试。但是在app
中写入库的InstrumentationTests
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。经过大量的研究,我找到了一个解决方案来获得library
的完整覆盖报告
在图书馆的build.gradle
文件中执行以下操作以获得覆盖
-
添加
apply plugin: 'jacoco'
-
启用测试覆盖范围,如下
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
,则会有一个名为combinedTestReportDebug
的默认任务。
你可以在安卓工作室右上角垂直栏的Gradle
菜单中找到它。
Gradle menu > :your-library > Tasks > reporting > combinedTestReportDebug
或
从在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范围或失败的测试
对于失败的测试:your-library/build/reports/androidTests/connected/index.html
对于覆盖率报告:your-library/build/reports/coverage/debug/index.html
我希望这能有所帮助。
更新:
对不起,我忘了提到下面的步骤,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
任务在库渐变任务中可见。
buildscript {
repositories {
jcenter()
}
dependencies {
...
classpath 'com.vanniktech:gradle-android-junit-jacoco-plugin:0.13.0'
...
}
}
...
apply plugin: 'com.vanniktech.android.junit.jacoco'
