If I am to suggest someone a resource for some sensible work for quick onboarding with key learnings from courses, I would not hesitate to recommend them summary books such as these. It is way better than any superficial crap floating on the internet. I admire the passion, efforts put in, & the intent with which Rahul Parwal & Khushboo Rajpurohit wrote this e-book.

The book is convenient for revision, to go through, again and again, to refresh one's thoughts, rather than having to endure lengthy and time-consuming lectures for revision. For one time, the entire lecture is fine. For me, these lectures are more about enhancing the thinking process. Going through these lectures requires a lot of time, and this book is incredibly helpful!

Testers have multiple things to take care of but the most popular prioritized task is to find bugs in the system. But does it indicate the end of good testing? Knowing and learning a problem and getting it solved are 2 different things and require distinct skillsets. It only makes sense when you find the bugs and also push to get them resolved. Bug Advocacy”, book by Rahul Parwal and Khusboo Rajpurohit did an excellent job with touching the basics on Bug Advocacy.
