For websites requiring interactive operations, using pytest for API testing alone is insufficient as it doesn’t cover frontend interactions. Previously I used Selenium for browser control in web scraping tasks, but now I’ve found that Microsoft’s Playwright can also control browsers for automated testing, and it’s even simpler to use than Selenium since it supports automatic test case recording.

For the past six months, a significant part of my work has been maintaining the company’s website. Since I took over the code midway, there’s always a risk of introducing new bugs during maintenance. Therefore, as required by my supervisor, I learned how to implement automated testing.

chatGPT has been popular for so long, but I only created an account yesterday when I wanted to use it to generate some content. As many people online have said, while it may be unreliable on professional questions, for writing code - since I ultimately need to run and test it myself - practice yields true knowledge. Having a roughly correct direction is already helpful!

A while ago, I implemented an interesting interactive data processing case using Dash. Here, I’ll record it.

I’ve been extremely busy lately, with too much work to finish… so I haven’t had much motivation to write. However, this time I’ve applied what I’ve learned in the past six months to build my first web app with database operations, which is worth commemorating. Although I’m short on time, I’ll start with the text and add images later.
