Although many books have been written on software testing over the years, Gayathri Mohan's Full-Stack Testing, released earlier this year with O'Reilly, is unique: by taking a comprehensive look at many different aspects of testing across the development lifecycle, it emphasises the importance of a truly holistic approach.  In this episode of the Technology Podcast, Gayathri joins hosts Rebecca Parsons and Ken Mugrage to discuss the book, her experience as a QA and testing's important and changing role in the future of software development.
