Is it security-wise necessary to clear cache of a browser after manual testing?

Hello everybody :smile: We are testing our website with LambdaTest. Everything seems to be fine, however I have a question, which I could not find an answer for when googling.

Imagine I am testing my website example.com, and I am logging in into my website to test whether it is working correctly on Safari. After I am finished with the testing, do I need to clear the browser cache by myself (e.g. removing all cookies, clearing localStorage, deleting browser history etc.)? I don’t want the next user of the virtual machine to land on my website in a logged in state for example :smile:

Why I am asking: after testing with LambdaTest, we have some suspicious activities on our load balancer every day. Maybe this is a coincidence, but I am sure I did not clear the cache after manual testing in the browser sometimes.

So, is it a good practice to clear the browser cache? Or can I rely on LambdaTest that all data will get erased after I end the testing session? Just wanted to ask to be sure.

Thank you very much for the answer. Best regards, Oleg

Once the session ends, the device undergoes a sanity check during which all information stored by you within the session is deleted. After this process, the device is restored to its original state, ensuring that no information from the previous session is retained.
