Handling Dp method for not detecting the sheet/cells.

Description: 

Data-Driven Testing is an important aspect of Selenium automation. One of the popular ways of implementing Data-Driven Testing is by using Excel files. However, sometimes, users may encounter an issue where their Data Provider (DP) method is not detecting the sheets/cells from the Excel file.

Causes:

There can be multiple reasons for this error. Some of the common ones are

1. The Excel file path is incorrect or the file does not exist in the specified location.

2. The sheet name is incorrect or the sheet does not exist in the Excel file.

3. The cell range specified in the DP method is incorrect or the cells do not exist in the sheet.

Debugs:

Debug 1: Verify the Excel file path -

Check if the path specified in the DP method is correct and the file exists in the specified location.

Debug 2: Verify the sheet name -

Check if the sheet name specified in the DP method is correct and the sheet exists in the Excel file.

Debug 3: Verify the cell range - 

Check if the cell range specified in the DP method is correct and the cells exist in the sheet. You can try printing the cell values to verify if the cells are getting detected or not.

Debug 4: Verify the file format - 

Make sure that the Excel file is in the correct format (.xls or .xlsx) and is not corrupted.

Debug 5: Check for file access - 

Ensure that the Excel file is not open in any other program, as it can cause issues with file access.

Debug 6: Use a different method - 

If the above steps do not work, you can try using a different method for Data-Driven Testing, such as using a CSV or a JSON file.
