Controlling output with Google Test

By default, the output of a Google Test test program goes to the standard stream, printed in a human-readable form. The framework provides several options for customizing the output, including printing XML to a disk file in a JUNIT-based format. This recipe will explore the options available to control the output.

Getting ready

For the purpose of this recipe, let's consider the following test program:

    #include <gtest/gtest.h>

    TEST(Sample, Test)
    {
      auto a = 42;
      ASSERT_EQ(a, 0);
    }

    int main(int argc, char **argv)
    {
      ::testing::InitGoogleTest(&argc, argv);
      return RUN_ALL_TESTS();
    }

Its output is as follows:

[==========] Running 1 test from 1 test case.
[----------] Global test environment set-up.
[----------] 1 test from Sample
[ RUN ] Sample.Test
f:/chapter11gt_05/main.cpp(6): error: Expected: a
