How to print Google Test output to a text file?

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?

I run the tests using

from the console:
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 runTests command to a file:

cmake CMakeLists.txt && make && ./runTests > test_output.txt

Also, see this which explains why you do not need the & I had used in my comment. As Awaken's answer says, the & redirects both the stdout and stderr to the same file. But since googletest output always goes to stdout you may leave out the &.
