Code coverage tools in Java
提问by emkrish
Are there any such code coverage tools in Java that give the different paths in the program. Basically the idea is to ensure that all loops and nested loops are covered during execution. That is to be able to ascertain if all the loops in a code base have been executed at least through one iteration.
Java中是否有任何此类代码覆盖工具可以提供程序中的不同路径。基本上这个想法是确保在执行过程中覆盖所有循环和嵌套循环。那是为了能够确定代码库中的所有循环是否已经至少通过一次迭代执行。

Cobertura, EMMA and even Clover only do branch/decision coverage(in addition to line/statementcoverage, of course). Clover also provides methodcoverage (which simply measures if a method was entered at all during execution).
Cobertura、EMMA 甚至 Clover 只进行分支/决策覆盖（当然，除了行/语句覆盖）。Clover 还提供方法覆盖（它只是测量在执行期间是否输入了方法）。
For pathcoverage (plus line/statement coverage), try JMockit Coverage.
对于路径覆盖（加上行/语句覆盖），请尝试JMockit Coverage。
A sample report can be found here.
可以在此处找到示例报告。
Actually, as of now this is only an initial version of the new path coverage support, which I still need to improve.
实际上，到目前为止，这只是新路径覆盖支持的初始版本，我还需要改进。

I'd go with JaCoCoIt's an open source tool (replacement for EMMA) distributed under Eclipse's public license.
我会选择JaCoCo它是一个开源工具（替代 EMMA），在 Eclipse 的公共许可下分发。
