Participating on a project as a Tester has some interesting contrasts and some unexpected experiences when compared to participating as a Developer. Having experienced both, I was most surprised with skepticism, concern, general invisibility, and subtle questions about my qualifications as a Tester. It seemed because I was a Tester, I had no credibility.The start of the project is the best time to make an impression, establish your identity, and build credibility. Every Tester knows this but many times other priorities interfere with establishing a foundation for working with other team members and providing value to the project as a Tester. In this session, I present an approach to challenging mindsets and establishing credibility: be available, visible, and vocal. Be available to meet team members, be visible at introductory meetings, be vocal about the role of testing in your project. Building upon these lays the foundation for participation in key meetings, improving testability, getting bugs fixed, and engaging team members in testing. The session includes tips for participating in requirements, design, and code reviews. It concludes with methods of building credibility with your testing team, using delegation to build new test leaders, and advocating for testability in project products.
