I have a question I may already have the answer, but who knows

In my test suite I have many modules. Some of them have bound variables defined by a table in the data sources (cross-browser testing with FF, IE and Chrome). But when I debug the module, I cannot run the module alone because the variable waits the data source.
To test I can change the module and put the name of the browser for example, but sometimes I forget to change back the right value.
Do you have a workaround?
I hope you fully understood my issue

Thanks in advance!
