Fix unit test failure

* Fixed enforcer plugin failure due to TestNG mismatch
versions.
* Bumping TestNG dependency to 6.8.8 triggered JUnit
assert class not found. So fixed all unit tests to use
TestNG asserts.
* Fixed the build failure for the module ios-grid
due to missing testng xml file.
good question. I think I spent quite some time getting rid of it :)
