如何在命令行中使用MS代码覆盖工具？ [英] How to use MS code coverage tool in command line?

问题描述

我有以下C ++代码。

I have the following C++ code.

#include <iostream>
using namespace std;

int testfunction(int input)
{
    if (input > 0) {
        return 1;
    }
    else {
        return 0;
    }
}

int main()
{
    testfunction(-1);
    testfunction(1);
}

我编译它以获得执行

cl /Zi hello.cpp -link /Profile

$ b b

然后，我执行并生成.coverage二进制文件。

Then, I instrument the execution and generated the .coverage binary.

vsinstr -coverage hello.exe
start vsperfmon -coverage -output:mytestrun.coverage
vsperfcmd -shutdown

在VS2010中的覆盖文件，我的结果没有任何东西。

When I open the coverage file in VS2010, I got nothing in its results.

可能有什么问题？
我按照此帖。

What might be wrong? I followed the instructions in this post.

推荐答案

您需要在监视器启动后运行程序：

You need to run your program after the monitor starts:

1. > vsinstr / coverage hello.exe


2. > start vsperfmon / coverage /output:mytestrun.coverage


3. > hello.exe


4. > vsperfcmd / shutdown

1. > vsinstr /coverage hello.exe
2. > start vsperfmon /coverage /output:mytestrun.coverage
3. > hello.exe
4. > vsperfcmd /shutdown

运行步骤3时，您应该在vsperfmon.exe中看到一些通知.exe已启动。

When you run step 3, you should see some notification in vsperfmon.exe that hello.exe has started.

如果您打算进行多个测试运行，则只需运行步骤2-4。换句话说，你只需要在生成二进制文件（步骤1）后对其进行一次测试。

If you plan on doing multiple test runs, you only need to run steps 2-4. In other words, you only need to instrument your binary (step 1) once after it's built.
