Tester in Agile project<\/p>\n

I received an email where the sender wrote: \u201cSomeone told me that in Agile method, there is NO jobs for tester. As a tester, I am worry about my future since my company is planning to use Agile method (Scrum) soon. Please advise.\u201d<\/p>\n

 <\/p>\n

My answer: \u201cThe Agile approach works well for small projects (3 to 8 people). When it comes to testing, the development team itself does its own testing.\u00a0There is no distinguish roles between developers and testers as team members often switch roles. In other world, with Agile approach \u201cdevelopers\u201d and \u201ctesters\u201d are part of the development team.\u00a0For example, with Extreme Programming, there is an approach called \u201cPair programming\u201d where two people work together in one task. One plays the role of \u201cDeveloper\u201d (or Driver) and the other play \u201cTester\u201d (or Observer). They observe each other\u2019s works, learn from each other, review each other\u2019s code, and provide feedbacks to each other. The developer learns testing skills from tester and the tester also learns coding skills from the developers. Eventually they switch roles as they continue to work together. However, it does NOT mean the tester\u2019s job is eliminated. As a tester, you will be included in the development team where you will also learn programming and work as developer too.<\/p>\n

I know that this is different from the waterfall approach where developers only test their own code (Unit test) then give it to testers for additional tests (verification and validation).\u00a0Unless your company is ONLY focusing on small projects, there will be larger project too (Maybe 20, or 50, or 200 people) so there is still a need for independent testing team. Large project is usually complex, critical, with many technical difficulties for one person to assume many roles. Larger projects also require certain expertise and experienced people who has certain specialty so you should NOT worry that testing job will go away soon.<\/p>\n

For most large project, the developing team would focus on requirements, architect, design, code, and unit tests. The test team is working in parallel with the development activities but focuses more on specific problems which are difficult for the development team to find and provide feedbacks to the development team.\u00a0This types of testing is similar to the \u201cPair programming\u201d approach in Agile but the testing team is experienced and trained to performs certain tests (Verification and Validation) to ensure quality is \u201cbuilt in\u201d. For example, the test team will focus on the integration issues (Integration tests) to ensure that the development team\u2019s solution will work well with existing systems or solutions done by other development teams. For complex system, the test team may focus on the security issue (Security testing) and make sure that it is well designed and fits into current systems. In most large projects, there are several development teams, each is concentrating on certain functions or specific area, but there should be only one independent test team to oversee everything and make sure that the develop system will work (Verification and Validation tests).<\/p>\n

Unless you really like to work permanently as a tester, I believe learning new skills, new knowledge is a natural progression in a software career. I would NOT hesitate to learn about Agile and prepare to work in new roles such as programmer, developers, or even Scrum Master. The more knowledge you have, the more secure is your job. Do NOT worry about the company\u2019s direction to move to Agile but focus on what you can learn and what you can do to improve your career. You want to be the best software professional possible, no matter what roles and what responsibilities\u201d.<\/p>\n","protected":false},"excerpt":{"rendered":"
