When I started testing this feature, it looked quite simple. On a page, the user would be provided an option to view the default number of entries. This was helpful compared to the current UI where the default was set to X. Also, this feature was supposed to be a widget level change which meant that it can be applied across pages with minimal or no change. Also, one could jump to a particular page using a button.
The typical test ideas that came to my mind were:
- Change the defaults
- Compare with production
- Try every value
- Try combination of the Jump button and the drop down to change the default value.
But as I started testing, I discovered few interesting issues which I would like to highlight here:
Issue 1: Incorrect text displayed when the product of default value (drop down) and Jump to page value equaled 1000. The text read 'Displaying 1-1000' instead of 990-1000
First of all, I wanted the test data setup part to be automated. I wanted to have more than 1000 entries for my testing. Thanks to my colleague Vinod G Srinivas, who gave me a quick script to create X number of entries. This particular bug was present only for the value 1000 and worked fine for any value below 1000 and up to 2000.

For example:
This was an example of a bug at the boundary. Strange things happen at the boundary. To our surprise, this bug is existing in production. With 10 as the default, someone would had to navigate till the 100th page to see this bug. No one reported till now.
Issue 2: Action on records messes up the page count
For example, I have set 25 as the default in the drop down. I populate 26 records. I can now navigate to page 2. If I delete the record on page 2, I am left with 25 records and should be redirected to page 1. But guess, what happened? I was left at page 2 without any records and the text which read: Displaying 26-26 records.

Issue 3: Switch between default values displays incorrect records
Suppose I had 11 records and default was set to 10. I saw the results in two pages. Without navigating to second page, I expect to see all 11 records when I switch the default to 25. Everything worked fine till now. When I switched back to 10 from 25, I still saw 11 records. The switch back to 10 as default was not respected.

Think about these three issues. These don't look straight forward. You play with the software and slowly you get the ideas. And these bugs were interesting according to me. I had never predicted that I would have seen these issues when I first got the feature. And that is what makes me test - The uncertainty, the joy of exploration and investigation. Till next time, do share your interesting bugs.
