requirements

I am new to testing and my mentor at the company is asking me to get my base strong with regards to manual testing. I know java and made few demo projects with selenium - browser automation and rest assured - API testing . They are expecting me to have better test cases coverage and base needs to be strong . So , anybody knows few blogs/resources from which I can get my foundation strong?

Discover practical ways to plan and prepare for the work, to communicate with testers and analysts about what needs to be done, and to create requirements that are understandable to everyone.

I worked as a manual tester for 2 years and took a break because I had kids. Now when I apply for jobs, I couldn't get a call back as there is a gap in my career. It’s been 3 years since I worked and I live in UK.

I have taken selenium automation testing course online.And what are the recent technologies/tools that I have to learn so I can improve.

I have been in software test for medical devices/software for the last five years, across three different companies. With my prior two organizations we formally validated our web-based software products only for the one or two most recent versions of Internet Explorer (at those times). Having our software work in Chrome or Firefox were nice-to-haves, but we did not communicate to our customers that we supported those browsers,  I'm soon to start work on a major release of an existing product, and the Project has decided to officially test/validate only Chrome, based on our current knowledge that the current release has known issues with IE. Seems to me we could be taking the easy way out, and not taking into consideration what our users use (often by policy). Apparently we don't currently have that information, though, I have brought it up that we should try to figure that out.
