The <span class="emphasis"><em>UTF</em></span> 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.
|
|
</p>
|
|
<p>
|
|
The <span class="emphasis"><em>UTF</em></span> 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.
|
|
</p>
|
|
<p>
|
|
During test module initialization the <span class="emphasis"><em>UTF</em></span> 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
|
|
<span class="emphasis"><em>UTF</em></span> is:
|
|
</p>
|
|
<pre class="programlisting"> --<command_line_argument_name>=<argument_value>
|
|
</pre>
|
|
<p>
|
|
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.
|
|
</p>
|
|
<p>
|
|
The corresponding environment variable name is also case sensitive and is required
|
|
to exactly match the name in the parameter specification.
|
|
</p>
|
|
<p>
|
|
All information about supported parameters is summarized below in the reference
|
|
section.
