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.
