How to insert Data in Text boxes from attached file during test execution?

Several ways, actually.



Say, for example, your TextBox is referenced as Aliases.MyApp.MyTextBox.



Depending upon the application, component, etc., any number of these could work.

Aliases.MyApp.MyTextBox.Keys("This is my text")

Aliases.MyApp.MyTextBox.SetText("This is my text")

Aliases.MyApp.MyTextBox.wText = "This is my text"

Aliases.MyApp.MyTextBox.value= "This is my text"

Thanks for the reply

Can i insert text to text boxes from file ?

Sure thing.  It's just a matter of pulling the data out of the file and then using one of the above methods to do the data entry.  Search the help for topics on Data Driven Testing.

Can you post me any sample code for this scenario?

will be grateful to you ..:P
