// A "skipped" test has a specific meaning in Facebook infrastructure: the
// test is in good shape and should be run, but something about the
// compilation or execution environment means the test cannot be run.
// Specifically, there is a hole in intended testing if any
// parameterization of a test (e.g. Foo/FooTest.Bar/42) is skipped for all
// tested build configurations/platforms/etc.
//
// If GTEST_SKIP is available, use it. Otherwise, define skip as success.
//
// The GTEST macros do not seem to print the message, even with -verbose,
// so these print to stderr. Note that these do not exit the test themselves;
// calling code should 'return' or similar from the test.
