Failed to locate the label inside a webpage

Fri Sep 23, 2011 11:20 am

1.Test suite pointing to Selenium Remote web driver
2.Created tests using Java scripts; text fields, radio buttons,check boxes etc inside web page are identified using 'ID' at the lower level pointed by fire bug utility in mozilla fire fox

3.Each Main service/item in the webpage has a label similar to this eg 'ygtvlabelel21' and that has been declared in a property file under 'Src/main/resources'

While running the test from Eclipse, the following error displayed and failed to locate the service/item in the tree view

But still the below error is displayed, it failed to identify the item

In setUpBaseTest method
