Re: [QF-Test] How to compare the component displayed value

[Gregor Schmid <Gregor.Schmid@?.de>]

Hi Kevin,

the problem is that you are using rc.getComponent as the test in an
'If' node. You can't do that because rc.getComponent is solely
available in the SUT whereas 'If' node tests are evaluated in
QF-Test's Jython interpreter.

Instead, use a 'Fetch text' node to read the text of the intended
target component and store it in a variable, e.g. "text", then use

rc.lookup("text") != "0.00"

in the test of the 'If' node.

NB: In general rc.lookup("text") is preferable to "$(text)" because it
doesn't throw an exception in case of line breaks or special escape
sequences.

Best regards,
    Greg
