In the ParameterRenaming_Left class, the "bar" method has an one integer parameter which is named test. (line70)
In the ParameterRenaming_Right class, this integer parameters' name changed with testx.
ParameterRenamingTest compares the ParameterRenaming_Left class and ParameterRenaming_Right class, after that it controls whether that the bar method's parameters' name change.
