and my selector look likes below
Please help me to understand why i am getting the above error , i am just trying follow the walk through steps
Looks like the selector you have provided for the attach browser activity is wrong. For the attach browser, you have to provided a selector for a open browser window so that it can use that selector to identify which browser window/ tab you want to work on with the rest of the activities you have inside the attach browser activity. So, once you add the attach browser activity, click on the three lines and selector on indicate element on screen. Then, once the indication mode is active, use it to select the browser window you will be working on…
Thanks for response. I did select as mentioned in the above response and it’s working (no result).However, as per assignment 6 after indicating the browser tab with the help of relative selectors we need to choose relative element first name and modify the selectors as shown above, after doing that I am getting the above error
alright… So lets do this to figure out which one of those are throwing the error.
Right click on the attach browser and click on Toggle break point. This will add a red color circle next to attach browser. Now run the program in Debug mode. This will allow you to gain control of the execution once it reach the attach browser. Once it gets there, the activity will be highlighted in yellow. Now do a step by step execution.
So once it get to attach browser, and you click on next step, if it moves to the next step, that means the selector of the attach browser is fine. So like wise do a step by step to locate which activity is throwing the error. Then, based on that, we’ll get together and fix the problem selector
