I'm implementing an extension to QTP using the Web Extensibility Toolkit. If my JScript function that implements the QTP action encounters an error (e.g User gave wrong argument values), I want the QTP to stop the test execution and notify the user about the error. I want it to act as a normal error in QTP and ask if the user want to debug\retry\skip\stop execution.
How can I do it?
If you throw an exception with a string then the message you throw is presented in QTP like any other script error (StopRetrySkipDebug)
throw "I'm sorry, Dave. I'm afraid I can't do that";
However from trying it out it looks like this only works with string literals, if you concatenate a literal with a variable it shows only the literal part:
throw "I'm sorry, Dave. I'm afraid I can't do " + param;
QTP displays:
I'm sorry, Dave. I'm afraid I can't do
When using a string variable:
var msg = "I'm sorry, Dave. I'm afraid I can't do " + param;
throw msg;
QTP displays (X's to protect the guilty):
An error occurred while running the Web extensibility handler for the 'Xxx' method Error details:
