Читаем Agile Testing: A Practical Guide for Testers and Agile Teams полностью

In all cases, managers need lots of patience during what might be a long transition to a high-functioning agile team. It’s their job to make sure they provide the necessary resources and that they enable every individual to learn how to do high-quality work.

A Testing Manager’s Transition Tale

Tae Chang manages a team at DoubleClick that conducts end-to-end testing to ensure that all integration points, both up and downstream from the target of change, are covered. When they implemented Scrum, the development teams were reorganized into numerous application teams. Communication problems resulted in missed dependencies, so Tae’s team stepped up to help make sure problems were detected early.

Tae told us, “I believe agile development effectively magnified the importance of cross-team communication and a coordinated end-to-end testing effort. It was not easy to work out a noninvasive (in terms of fitting into current sprint structure) integration testing process; in fact, we are still tweaking it, but the overall benefit of such a testing effort is apparent.” Their teams began to slide into the “mini-waterfall” trap. “In retrospect,” explains Tae, “one of the reasons for this is because we started with the agile process before internalizing agile practices.”

Knowing that test automation and continuous integration were key, the teams at DoubleClick came up with new ideas, such as a specialized build and automation team to help the development teams cope. They brought in expert training to help them learn TDD and pair programming. They started taking steps to address their legacy system’s technical debt.

Tae’s team attends all of the sprint planning and review sessions, using both formal and informal communication to facilitate cross-functional communication and coordinate testing and releases. He has found that it helps to keep meetings small, short, and relevant. He’s also a proponent of everyone sitting together in an open work area, as opposed to sectioned-off cubes.

Tae offers the following advice to testers making the transition to agile:

“Agile development in general will initially frustrate testers in that they will not have access to full requirements documentation or defined stages of testing. In my view of agile development, at any given moment, the tester will be engaged in tasks from multiple stages of the traditional development process. A tester can be sitting in a design session with engineering and product management (she should be taking notes here and start thinking of areas of risk where proposed code change will most likely impact) and on the same day work on automating and running test cases for the proposed changes. It’s a change in mind-set, and some people are quicker to adapt than others.”

Tae’s experience mirrors our own and that of many other teams we’ve talked to.

If you’re a QA manager, be prepared to help your testers overcome their frustrations with moving from defined, sequential testing stages to fast-paced iterations where they perform widely varied tasks on any given day. Help them adapt to the idea that testing is no longer a separate activity that occurs after development but that testing and coding are integrated activities.

If you’re a tester or other team member who isn’t getting the support you need in your transition to agile development, think about the difficulties your managers might be having in understanding agile development. Help them to understand what kinds of support you need.

Speaking the Manager’s Language

What do business managers understand best? It’s the bottom line—the ROI (return on investment). To get the support you need from your management, frame your needs in a context that they can understand. Your team’s velocity translates into new features to make the business more profitable. If you need time and funds to learn and implement an automated test tool, explain to management that over time, automated regression tests will let your team go faster and deliver more functionality in each iteration.

Lisa’s Story

My team needs big blocks of time to do risky refactoring, such as trying to split the code base into multiple modules that can be built independently. We also need time to upgrade to the latest versions of our existing tools, or to try out new tools. All of these tasks are difficult to integrate into a two-week sprint when we’re also trying to deliver stories for the business.

We explained to our management that if these “engineering” tasks were put off too long, our technical debt would accumulate and our velocity would slow. The number of story points delivered each iteration would decline, and new stories would take longer to code. It would take longer and longer for the business to get the new features it needed in order to attract customers.
