Fixing Whole System Bugs
Since Mr. Peter has reviewed my entire system, he pointed out some small bugs that could be enhanced to make it smoother. There were over 20 tasks, and it took me two days to complete. These tasks included fixing some input bugs, such as ensuring the page auto-focuses when navigating or when selecting items, as well as allowing decimal inputs for stock management.
In addition, I improved the workflow for stock adjustments. Now, when a user enters a wrong barcode, the system resets all states and refocuses the textbox. I also added a confirmation dialog to the payment edit section to ensure users do not accidentally click the button. Furthermore, I implemented some hotkeys: the Escape key now closes open dialogs, and the Enter key skips the need to press the submit button.
Create Voucher Page
After fixing all the bugs, the system now runs more smoothly than before. I then continued working on the voucher page. The voucher page is easier to create because it only requires three data fields to be uploaded to the API. However, one important thing to watch out for is ensuring that the “last valid date” is not earlier than the creation date. If it is, the API will return an error. To prevent this, I added validation to the “last valid date” to ensure the voucher can be created successfully.
Research On How to Create 1,000,000 Records
After finished the voucher page, the whole system are almost done , but since others backend technologies are still haven’t done yet, so that Mr.Peter asked me to do some research on generating 1,000,000 records data and see how the system performance going on if data fully loaded. It modifies that if this system are being used for several years and look whether the system still can run smoothly. After two days of researching , I have founded a platform name cypress, it is a web testing tools, but it’s more on UI testing. After trying to create a test plan , it can create records smoothly. Unfortunately, Mr.Peter does not accept this type of solution, because it would not work when the UI position are being changed. After that I was trying to create another UI page to generate the data, how I do is just hardcode the data structure and run it in a loop according to the count what user want. But this would make several hours to generate 1,000,000 records.
