The --gtest_output=json option is supported from gtest 1.8.1 onwards.
Earlier versions output a warning about it being an unrecognized option,
and builds that #define GTEST_HAS_FILE_SYSTEM 0 output an error about it
being unsupported, but in both cases still continue outputting the same
plain text output as before and return an exit code of 0.
We now add that option and check for whether the JSON file is generated,
falling back to parsing the plain text output as before if it isn't or
if the environment variable NO_GTEST_JSON_OUTPUT is set.
The fake executor binaries are sensitive to parameter order. This commit
adds --gtest_output:json arguments to a number of tests added for the
new JSON parser. The argument order has been adjusted for the
invocations of those binaries.
