Difference between Variable Binding and Parameter binding,

[manishrn91]

Hi Team,

Could you please explain the difference between Variable binding and parameter tab.
Please see the attachment for reference.

and Which one is best supported for Data driven test case.

I use the Variable Binding list to bind data values from the Data Source IFF I'm using one to iterate a Test Case multiple times. My Parameters tend to come from the Test Case itself and any parent Test Cases e.g. constants or global parameters.

Sometimes I use a mix of both. I might iterate a Test Case with a set of data, but they might use some common constant from the Test Case or its parents.

I too would like a full detailed explanation of the expected use. A also agree with Stub's utilization. I tend to direct people to only use the "variable binding" if they plan on creating a data driven test otherwise just use parameters.

I'll also use parameters for environmental/configuration data such as user name & passwords that don't change between iterations, URLs, and whatever else hits me at a given moment.

Actually, the "Variable binding" area is probably misnamed. It is actually the area where you bind variables to a data connector's columns, so it really should be "Data Connector Binding" as opposed to the "Parameters" binding area at the bottom.

A variable is in a module (recording or user-code) and can be bound to either a data connector (using the "Variable bindings" section) or to a parameter (using the bottom "Parameters" section).

All good points. The way Ranorex uses terminology around "variables" can be very confusing for non-programmers and extremely annoying to experience programmers. I'd like to see some clarification or increased usability around the whole variable binding process. I don't know what it'd look like, but something to think about I guess.

Hi all,

In order to request a re-work of the variable binding-dialog, I would suggest adding an entry to our UserVoice. This would allow other customers, to vote for your idea.

Thank you for your understanding.

Sincerely,
Matthias
