Xamarin Studio上的代码覆盖率 [英] Code coverage on Xamarin Studio

问题描述

是否有可靠的工具可以帮助我们衡量单元测试的代码覆盖率？我主要在Xamarin项目中工作（在Xamarin Studio中）。

为了不堆积-1，我四处张望，但找不到成熟到足以可靠的东西。我不要求产品免费（但如果这样的话，那当然更好！）

解决方案

有代码Mono 4.x行中的coverage探查器（自2015年4月7日提交）。

如果您进行移动测试，但对您没有帮助在桌面平台上运行单元测试，您可以为Mono提供探查器选项：

 -profile = log：coverage 
 
 coverage允许收集代码覆盖率数据
 covfilter = ASSEMBLY将程序集添加到代码覆盖率过滤器
添加+以包括程序集或-排除程序集
 filter = -mscorlib 
 covfilter-file = FILE使用FILE生成要过滤的程序集列表
  

在常规的 exe处理中，您最终得到：

 封面摘要：
 xCorFlags（/ Users / administrator /monocov/lib/xCorFlags.exe）覆盖26％（42种方法） -覆盖11个）
< Module> ？％覆盖（0种方法-1种覆盖）
 CorFlags.CorFlagsSettings 25％覆盖（4种方法-1种覆盖）
 CorFlags.MainClass 50％覆盖（2种方法-1种覆盖）
 CorFlags。 CommandLineParser 40％覆盖（20种方法-8覆盖）
  

因此，将配置文件选项传递给您的cmd行

获取详细的覆盖范围结果并完全集成到IDE（如VS）中。

，我对C＃的OS-X / Linux所知甚少，甚至还没有Windows / .Net上可用的工具。 ：-（

Is there a reliable tool that would help us measure the code coverage of my unit tests? I'm mostly working on Xamarin projects (in Xamarin Studio).

For the sake of not getting heaps of -1, I've looked around but couldn't find something mature enough to be reliable. I don't ask the product to be free (but it's of course better if it is ! )

解决方案

There is the code coverage profiler that is in the Mono 4.x line (since a April 7, 2015 commit).

It does not help you if you doing Mobile testing, but if you are running unit tests on desktop platforms you can supply the profiler options to Mono:

--profile=log:coverage

coverage             enable collection of code coverage data
covfilter=ASSEMBLY   add an assembly to the code coverage filters
                     add a + to include the assembly or a - to exclude it
                     filter=-mscorlib
covfilter-file=FILE  use FILE to generate the list of assemblies to be filtered

In normal "exe" processing, you end up with:

Coverage Summary:
    xCorFlags (/Users/administrator/monocov/lib/xCorFlags.exe) 26% covered (42 methods - 11 covered)
        <Module> ?% covered (0 methods - 1 covered)
        CorFlags.CorFlagsSettings 25% covered (4 methods - 1 covered)
        CorFlags.MainClass 50% covered (2 methods - 1 covered)
        CorFlags.CommandLineParser 40% covered (20 methods - 8 covered)

So, pass the profile options to your cmd line based runner (nunit, xunit, etc..) and you can get an overview of your coverage.

For detailed coverage results and fully integrated to a IDE (like VS), nothing I know about on OS-X/Linux for C# even comes close to the tools available on Windows/.Net. :-(
