我有以下项目结构:没有运行时使用的覆盖艾玛,JUnit和蚂蚁
- 的src/COM /虚拟/ abc.java
- src_tests /来/虚拟/ abcTest.java
- 构建.xml
我需要检查使用emma进行的测试所做的代码覆盖率。 从阅读艾玛+ junit的例子我得出一个结论,要获得一个报告,我需要做到以下几点:
- 编译“SRC”
- 编译“src_tests”
- 仪编译“src_tests” >“instrumented_src_tests”上“instrumented_src_tests”
- 运行JUnit用额外jvmarg
的问题是,在步骤4中应返回某种然后与“代表所使用的文件的ort'命令应该创建一个报告。我越来越
emma-report:
[report] processing input files ...
[report] 1 file(s) read and merged in 67 ms
[report] nothing to do: no runtime coverage data found in any of the data files
〜编辑 我附加了我的build.xml

它可能是一些小事...
此外,当使用emma.sources.dest 我得到这个在我的(唯一)测试
run-tests:

<jvmarg value="-Demma.coverage.out.merge=false" />
您是否按照以下步骤设置了emma与ant http:/ /emma.sourceforge.net/userguide/ar01s03.html –
是的。 (还有很多)。此外,位于该链接中的信息并不能说明如何将它与junit一起使用,而是纯Java。 – Twisted
