Integrate googletest and googlemock libraries to 3rdParty
googletest and googlemock from release 1.8.0 have been copied
to the 3rdParty folder.
With this commit tests for Swift project can also written
using googletest and googlemock APIs. The test runners will
execute test suites written to either test library.
Passing —-xml to a test runner will now create two test
report XML files, namely $programName-report.cppunit.xml and
$programName-report.gtest.xml.
The ByteArrayTest has been converted to use googletest
instead of googlemock to serve as an example and test the
integration.
Test-Information:
Build all tests via ‘./scons test=all’ and verified all tests
are run.
Build all tests via ‘./scons test=all checker_report=1’ and
verified that two report XML files are generated per test
runner executed.
