The UTF supports multiple parameters that affect test module execution. To set the parameter's value you can either use a runtime configuration subsystem interface from within the test module initialization function or you can specify the value at runtime during test module invocation.
The UTF provides two ways to set a parameter at runtime: by specifying a command line argument and by setting an environment variable. The command line argument always overrides the corresponding environment variable.
During test module initialization the UTF parses the command line and excludes all parameters that belong to it and their values from the argument list. The rest of command line is forwarded to the test module initialization function supplied by you. The command line argument format expected by the UTF is:
--<command line argument name>=<argument_value>.
The command line argument name is case sensitive. It is required to match exactly the name in parameter specification. There should not be any spaces between '=' and either command line argument name or argument value.
The corresponding environment variable name is also case sensitive and is required to exactly match the name in the parameter specification.
All information about supported parameters is summarized below in the reference section.
