What are the limitations of Selenium?

Question

What are the limitations of Selenium?

Answer

The main limitations of selenium are: You can only perform tests in web applications, not for desktop or mobile. (But other tools are available to automate desktop application GUI tests.) Captcha and barcode reading cannot be automated with Selenium. Manual testing is needed for them. The user who is going to perform automatic tests with Selenium Python must have previous knowledge of Python.
