Some agile teams try to prepare in advance of the next iteration, perhaps by writing high-level test cases, capturing business satisfaction conditions, or documenting examples. It’s a tricky business that might result in wasted time if stories are re-prioritized or greatly changed. However, distributed teams in particular need extra feedback cycles to get ready for the iteration.
Lisa’s Story
Our remote team member used to be our on-site manager. He’s a key player in helping the business write and prioritize stories. He has in-depth knowledge of both the code and the business, which helps him come up with creative solutions to business needs. When he moved to India, we looked for ways to retain the benefit of his expertise. Meetings are scheduled at times when he can participate, and he has regular conference calls with the product owner to talk about upcoming stories. We’ve had to switch from low-tech tools such as index cards to online tools that we can all use.
Because the team was willing to make changes in the way we worked, and looked for tools that helped keep him in the loop with ongoing changes, we were able to retain the benefit of his expertise.

Some teams have analysts who can spend more time with the business experts to do some advance planning. Each team has to strike a balance between brainstorming solutions ahead of time and starting from scratch on the first day of each iteration. Agile testers go with the flow and work with the team to accommodate changes.
Automated testing is one key to the solution. One thing we know for sure: No agile team will succeed doing only manual testing. We need robust automation in order to deliver business value in a time frame that makes it valuable.
Self-Organize
The agile tester is part of a self-organizing agile team. The team culture imbues the agile testing philosophy. When programmers, system administrators, analysts, database experts, and the customer team think continually about testing and test automation, testers enjoy a whole new perspective. Automating tests is hard, but it is much easier when you have the whole team working together. Any testing issue is easier to address when you have people with multiple skill sets and multiple perspectives attacking it.
Lisa’s Story
My team is a good example of a self-organizing team. When we implemented Scrum, we had a buggy legacy system and no automated tests. Making any changes to the code was risky at best. Our manager probably had some excellent solutions to the problem, but he didn’t suggest them. Instead, we explored the issues and came up with a plan.
The programmers would start implementing new stories in a new, testable architecture, using test-driven development. The testers would write manual regression test scripts, and the entire team—programmers, testers, the system administrator, and the DBA—would execute them on the last two days of every iteration. The testers (at the time, this meant me) would work on an automated regression smoke test suite through the user interface. Eventually, the architecture of the new code would let us automate functional tests with a tool such as FitNesse.
We implemented this plan in baby steps, refining our approach in each iteration. Using the skills of every member of the team was a much better approach than my going off and deciding the automation strategy on my own.

When an agile team faces a big problem, perhaps a production showstopper or a broken build, it’s everyone’s problem. The highest-priority issues are problems for the whole team to solve. Team members discuss the issue right away and decide how to and who will fix it.
There’s no doubt that Lisa’s manager could have mandated that the team take this approach to solving its automation problems, but the team itself can come up with the most workable plan. When the team creates its own approach and commits to it, its members adopt a new attitude toward testing.
Focus on People
Projects succeed when good people are allowed to do their best work. Agile values and principles were created with the aim of enabling individual and team success. Agile team members should feel safe and not have to worry about being blamed for mistakes or losing their jobs. Agile team members respect each other and recognize individual accomplishments. Everyone on an agile team should have opportunities to grow and develop their skills. Agile teams work at a sustainable pace that lets them follow disciplined practices and keep a fresh perspective. As the Agile Manifesto states, we value individuals and interactions over processes and tools.
In the history of software development, testers haven’t always enjoyed parity with other roles on the development team. Some people saw testers as failed programmers or second-class citizens in the world of software development. Testers who don’t bother to learn new skills and grow professionally contribute to the perception that testing is low-skilled work. Even the term “tester” has been avoided, with job titles such as “Quality Assurance Engineer” or “Quality Analyst” and team names such as “QA Department” given preference.
Agile teams that adhere to the true agile philosophy give all team members equal weight. Agile testers know they contribute unique value to their teams, and development teams have found they are more successful when their team includes people with specific testing skills and background. For example, a skilled exploratory tester may discover issues in the system that couldn’t be detected by automated functional tests. Someone with deep testing experience might ask important questions that didn’t occur to team members without testing experience. Testing knowledge is one component of any team’s ability to deliver value.
Enjoy
Working on a team where everyone collaborates, where you are engaged in the project from start to finish, where business stakeholders work together with the development team, where the whole team takes responsibility for quality and testing, in our opinion, is nothing short of a tester’s Utopia. We’re not alone in believing that everyone should find joy in their work. Agile development rewards the agile tester’s passion for her work.
Our jobs as agile testers are particularly satisfying because our viewpoint and skills let us add real value to our teams. In the next section, we’ll explore how.
Adding Value
What do these principles bring to the team? Together, they bring business value. In agile development, the whole team takes responsibility for delivering high-quality software that delights customers and makes the business more profitable. This, in turn, brings new advantages for the business.
Team members wear many hats, and agile development tends to avoid classifying people by specialty. Even with short iterations and frequent releases, it’s easy to develop a gap between what the customer team expects and what the team delivers. Using tests to drive development helps to prevent this, but you still need the right tests.
Agile testers not only think about the system from the viewpoint of stakeholders who will live with the solution but they also have a grasp of technical constraints and implementation details that face the development team. Programmers focus on making things work. If they’re coding to the right requirements, customers will be happy. Unfortunately, customers aren’t generally good at articulating their requirements. Driving development with the wrong tests won’t deliver the desired outcome. Agile testers ask questions of both customers and developers early and often, and help shape the answers into the right tests.
Agile testers take a much more integrated, team-oriented approach than testers on traditional waterfall projects. They adapt their skills and experience to the team and project. A tester who views programmers as adversaries, or sits and waits for work to come to her, or expects to spend more time planning than doing, is likely to cling to skills she learned on traditional projects and won’t last long on an agile team.
