I have met over the years many types of testers. Many types of professionals, with various core skills. Overall, they all fill a group that aims for the same objective, and together, with those various skills, create a more effective team.
I have a developer and very technical background, and worked on IT Security as well. I have brought many of my experiences from there to the Quality Assurance world.
Deep understanding of software, and SFDC, is also a key factor to complement your professional profile, ultimately helping you to be more effective and even efficient, because you may know where to look for bugs, errors, mistakes, and may know in advance how to trigger them due to your experience.
Some of the things I took from IT Security:
- Breaking software, files, outputs, packets, formats.
- Secure code.
- Validate all inputs, always, from everyone.
- Pay extra attention to how the memory is being used/managed. This greatly changes from language to language.
- Certain non-functional requirements, often not defined, can make a difference for the acceptance criteria of any software development.
