How to print Google Test output to a text file?
提问by RobotEyes
I have gtest up and running using code as shown below. I would like to print the test output to a text file as opposed to displaying it in the console. Is there a way of doing this?
我使用如下所示的代码启动并运行了 gtest。我想将测试输出打印到文本文件，而不是在控制台中显示它。有没有办法做到这一点？
I run the tests using cmakefrom the console: cmake CMakeLists.txt && make && ./runTests.
我cmake从控制台使用运行测试：cmake CMakeLists.txt && make && ./runTests.
#include "cw-test.c"
#include <stdio.h>
#include <gtest/gtest.h>
TEST(InputValidationTest, ValidateEntryLine)
{
...
}
...
int main(int argc, char **argv) {
testing::InitGoogleTest(&argc, argv);
return RUN_ALL_TESTS();
}

You can redirect the output of your runTestscommand to a file:
您可以将runTests命令的输出重定向到文件：
cmake CMakeLists.txt && make && ./runTests > test_output.txt
Also, see thiswhich explains why you do not need the &I had used in my comment. As Awaken's answer says, the &redirects both the stdoutand stderrto the same file. But since googletestoutput always goes to stdoutyou may leave out the &.
另外，请参阅这解释了为什么您不需要&我在评论中使用的。正如 Awaken 的回答所说，&将stdout和重定向stderr到同一个文件。但由于googletest输出总是到stdout你可能会遗漏&.

crayzeewulf's comment will work for any Unix program. What "&>" means is to redirect output in "stdout" and "stderr" to some other location you specify.
crayzeewulf 的评论适用于任何 Unix 程序。“&>”的意思是将“stdout”和“stderr”中的输出重定向到您指定的其他位置。
