RE: Implement global variable for Testcase number to execute from excel.
I am using Selenium webdriver with Testng for automation with data driven module where i am reading the testcases data from excel. I have hard coded the row numbers for each test case . If i want to add any cases in the middle again i have to change the numbering of all the cases. So how can i solve this issue.
I think i mis read your question.
I hope you are looking for a dynamic way to associate your test cases with right test data in the Excel sheet. I request you to go through the following links in sequential order:
Constant Variables : http://www.toolsqa.com/selenium-webdriver/constant-variables/Data Driven Technique : http://www.toolsqa.com/selenium-webdriver/data-driven-testing-excel-poi/
User Functions : http://www.toolsqa.com/selenium-webdriver/user-defined-functions/
In the last link I have told how to pick up the testcase name from excel to get the test data of the current test cases dynamically.
