/**

Note to understand tests:
- tests are run from the openwhisk as the current directory
- compiler (../../common/gobuild.sh) takes 3 arguments:
   <main> <source-dir-or-file> <target-dir>

 You create a proxy (NewActionProxy) with the target dir
 then invoke compilation with the source dir (implicit is 'main' as the function)

 You can test if compilation works with

   cd openwhisk
   ../common/gobuild.sh main _test/compile/c/exe ./action/c

   _test/precompile.sh simply copies files to test folder
   _test/postcompile.sh simply checks if the file is compiled
