Agile project development adheres to the Agile Manifesto and general concepts shared by all agile methodologies. As an Agile team member, an Agile tester has to follow the common principles agreed upon by the team.
The beliefs and principles of your team will guide you when you select practices and make decisions around how you want to work.
We believe the following concepts are vital for an agile tester:
Given that agile projects are driven by tests, it should come as no surprise that feedback plays a significant role in agile teams. The traditional role of the tester as a "knowledge supplier" renders her intrinsically valuable to an agile team. One of the most essential contributions of the agile tester is assisting the product owner or client in articulating requirements for each story in the form of examples and tests. The tester then collaborates with coworkers to develop executable tests based on these criteria. Testers, programmers, and other team members collaborate to execute these tests frequently and early in order to be continuously directed by useful feedback.
In this article, we will devote a great deal of effort to explaining how to do this. When the team faces difficulties, feedback can be used to assist in their elimination. Were we unable to deliver a user interface that met client expectations? Let's create a task card to remind us to collaborate with the customer on the next UI story's paper prototypes.
Is management concerned with how the job is proceeding? Display a large visible chart of daily tests prepared, executed, and passed. Display large-scale coverage of functionality, such as test matrices. Have difficulties stabilized the build? Lisa's team posted the number of days before it was time to release the build in order to keep everyone focused on completing stories on time. After it became a habit, they no longer need the visual signal.
Agile development includes delivering value in tiny releases that contain the exact capability that the client has recently prioritized. Typically, this involves limiting the scope. It is simple to become distracted by the client team's demand for cool features. Anyone can dispute these modifications, but testers frequently recognize their impact on the narrative because they must consider the testing ramifications.
Agile testers maintain a broad perspective. We can give the most important functionality in this iteration and add to it in subsequent iterations. If we allow additional features to slip in, we risk not meeting our deadlines. If we become overly preoccupied with edge cases and overlook fundamental functionality on the happy path, we will fail to meet the needs of the company.
Agile testers employ the same methodology. While one of our strengths is identifying test cases beyond the "happy path," we must first ensure that the happy path is functional. Later, we can add negative and border tests and automate tests for the happy path. Consider what adds the most value to the consumer at all times and be aware of your context. Adding negative tests to a safety-critical application is a fundamental must. During the estimating phase, testing time must be considered to ensure that adequate time is allocated for the iteration to produce a "safe" feature.
No team can function effectively without effective communication. Today, when so many teams are geographically dispersed, communication is more important and more difficult than ever. The agile tester must seek out novel means of facilitating communication. It is a crucial part of her job performance.
Whenever a tester has a query about how a feature should function or what an interface should look like, he or she can consult with a programmer and a business expert. Testers should never impede direct customer-developer connection, but they can often aid in ensuring such dialogue occurs. Agile testers examine each story or theme from the customer's perspective, but they also comprehend the technical restrictions and constraints associated with executing features. Customers and developers can achieve a common language with their assistance. Business professionals and software engineers frequently speak distinct languages.
