我的主要项目是一个安卓库。 我已经创建了一个测试项目,其中包含一些单元测试。 测试运行良好,但我正在努力获得测试覆盖率。 当我生成覆盖率报告时,我只获得测试用例的覆盖范围, 但不是图书馆。 所以它几乎100%,因为100%的测试正在运行。 但这并没有帮助我说出图书馆的哪些部分已经过测试。
这就是我现在这样做的方式:
0) my project looks like this:
myLibraryProject <- this is my android library project
myLibraryProject/tests <- this is my android test project
1) build.xml file : (from myLibraryProject/tests directory)
>android update test-project --path . -m ../
2) Modify the ant.properties file :
#tested.project.dir=../
android.library.reference.1=..
3) only then can I run :
ant emma debug install test
如果我不执行步骤2),则步骤3)失败,因为无法安装库项目
真的很感激任何帮助!
答案 0 :(得分:0)
所以这是我找到的解决方案:
在测试项目中创建一个新的build.xml 从android sdk build.xml文件中复制“test”目标(我使用过sdk20预览版2)
修改源路径以指向报告部分中的库项目
这是我现在使用的那个:

<!-- Application package of the tested project extracted from its manifest file -->
<xpath input="${tested.project.absolute.dir}/AndroidManifest.xml"

</then>
