You are using the old signature (without NAME|COMMAND) for which the 
documentation states [1]:
     "Unlike the above |NAME| signature no transformation is performed 
on the command-line to support target names or generator expressions."

Use the new signature instead e.g.:
     add_test(NAME RunTests COMMAND MyTest)
