Test::System::Helper - Helper for the Test::System
The purpose of this module is to provide the easiness of getting the list of nodes you want to test (if that is the case) and as well to let you fetch the value of the params you specified in your Test::System instance.
- get_nodes( )
Returns as an array the nodes you specified via Test::System. It basically joins splits by CSV the
TEST_SYSTEM_NODESenvironment variable value and returns it.
- get_param( $key )
Returns the parameter value of the given key.
It returns the parameter by checking the environment variable that stores its value. The name of the environments variables can be explained in the Test::System module, however a quick example will be:
use Test::System::Helper; my $value = get_param('foo'). # It will returns the value of: TEST_SYSTEM_FOO
Please note that since the values come from the environment the only type of data that will be returned will be scalar unless the key is not found then
undefwill be returned.
