int ElmerFoamFSI::ParallelTest	(	int	argc,
		char *	argv[]
	)

Drives the ElmerFoamFSI::TestObject.

Parameters

argc	number of string command line tokens
argv	string command line tokens

Returns

0 if successful, 1 otherwise

Drives the ElmerFoamFSI::TestObject, which should encapsulate all the tests for the ElmerFoamFSI namespace (and thus the project).

Command line documentation:

      elmerfoamfsi_test [-h] [-v [level] -o <filename> -l <filename> -n <TestName> ] 

      -h,--help
         Print out long version of help and exit.

      -v,--verblevel [level]
         Set the verbosity level. (default = 0)

      -o,--output <filename>
         Set the output file to <filename>. (default = stdout)

      -l,--list <filename>
         Set the list file name to <filename>. (no default). The list file should be a text file with one test name per line.

      -n,--name <TestName>
         Run test by name. (no default)
