問(wèn)題描述

我有以下 C++ 代碼.

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);
}

我編譯它以獲得執(zhí)行

cl /Zi hello.cpp -link /Profile

然后，我檢測(cè)執(zhí)行并生成 .coverage 二進(jìn)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

當(dāng)我在 VS2010 中打開(kāi)覆蓋文件時(shí)，我沒(méi)有得到任何結(jié)果.

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

可能有什么問(wèn)題?我按照這篇文章中的說(shuō)明進(jìn)行操作.

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

推薦答案

你需要在監(jiān)視器啟動(dòng)后運(yùn)行你的程序:

You need to run your program after the monitor starts:

1. <代碼>>vsinstr/coverage hello.exe
2. <代碼>>啟動(dòng) vsperfmon/coverage/output:mytestrun.coverage
3. <代碼>>你好.exe
4. <代碼>>vsperfcmd/shutdown

當(dāng)您運(yùn)行第 3 步時(shí)，您應(yīng)該會(huì)在 vsperfmon.exe 中看到一些通知，提示 hello.exe 已啟動(dòng).

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

如果您計(jì)劃進(jìn)行多次測(cè)試運(yùn)行，則只需運(yùn)行步驟 2-4.換句話(huà)說(shuō)，您只需要在二進(jìn)制文件(步驟 1)構(gòu)建后對(duì)其進(jìn)行一次檢測(cè).

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.
