Why this matters
Before you invest months in a career, you should know what the work looks like day to day and where the jobs actually are. Testing suits careful, curious people who like asking "what if?", and it is a real way into software teams. It also helps to be honest about the market from the start.
A tester's working week
Most testers work inside a product team with developers, a product manager and sometimes a designer. A typical week mixes these tasks:
- Reading what is planned. You read the description of a new feature and ask questions early: what should happen if the amount is zero? What if the user has no network?
- Designing tests. You write test cases: the steps and data to try, and what should happen.
- Running tests. You work through the app on real devices and browsers, following your test cases and also exploring freely.
- Reporting bugs. When something is wrong, you write a bug report clear enough that a developer can repeat the problem quickly.
- Confirming fixes. When a fix arrives, you check it works and that nothing nearby broke.
- Summarising. Before a release, you tell the team what was tested, what passed, and what risks remain.
Job titles vary: QA tester, QA engineer, software tester, test analyst. "QA" stands for quality assurance.
