The Basics of Agile Software Testing 

Agile software testing is a widely used term in IT circles. But what does the concept entail? In this article, you will learn the key essentials! 

Introduction 

Agilis, agileAgile, agile methodology: we often hear these terms in everyday life. But what do they mean exactly? In fact, it's not just one methodology; it would be more accurate to speak of agile methodologies. Since February 2001, when 17 American developers first articulated the basics of Agile in the Agile Manifesto, many methodologies have evolved and become established in practice, taking into account the core principles. Despite their diversity, they all aim for the same goals: achieving the highest possible customer satisfaction through frequent or continuous direct communication, implemented as efficiently as possible – preferably in short iterations. Whether it’s kanban, scrum, or another implementation, the main goal of agile development is to create a solution that can be frequently changed and responds immediately to market and customer needs, with the team always working on the most important tasks. 

The Concept and Benefits of Agile Software Testing 

When we talk about software testing When we talk about software testing, we often think of a situation where, after completing development tasks, the next project phase begins with the implementation and testing of the application. This is commonly seen in projects following a waterfall methodology. In an agile environment, however, we observe that this approach is not feasible: it is more accurate to speak of quality assurance rather than testing alone, which starts concurrently with software development. Agile software testing thus relies on continuous collaboration between developers and testers to provide a flexible and efficient environment for detecting errors as early as possible. Instead of focusing on time-consuming documentation tasks, the emphasis is on capturing essentials to prepare for the challenges posed by frequent iterations—and thereby changes—effectively.  

What are the principles of agile software testing? 

Although we can benefit greatly from implementing agile testing, the transition is often not easy, and practical challenges are common. However, understanding a few key principles can facilitate this transition. Let's explore these principles further. It's important to note that during agile software development, we can work with many methodologies; here, we will assume the most common one: presenting testing based on Scrum.

Shortening feedback time 

In a project implemented with the waterfall methodology, months or even half-years can pass between the requirements definition, development, and testing phases, not to mention the time when the client first sees the solution to their needs. In contrast, the application of agile testing allows feedback to occur every one to two weeks. The benefits of this are immediately apparent: the sooner feedback is received, the more easily the team can adapt to any changes, and the sooner it becomes clear if the project is heading in the wrong direction. 

Development and testing occur simultaneously 

We have all encountered situations where delays in successive project phases have repercussions in later stages: a development phase taking longer than expected leads to a backlog of tasks during the testing phase, often compromising quality. Implementing sequential phases in a two-week iteration is inherently challenging. However, the agile methodology uses a different approach for other reasons. Testers and developers work closely together from the beginning of development, from unit tests to UI and business tests. As a result, by the end of the development cycle, we are not just starting the testing phase but collaboratively delivering quality software. 

The close collaboration of the testing and development teams 

As we saw in the previous section, the entire team works simultaneously towards one goal: creating value. But how can this be implemented in practice? It's important for testers to be involved in the collaborative work from the very first planning tasks of the development cycle. This way, test case planning can also be done jointly, considering the sprint goals. The team needs to be mutually aware on a daily basis of what each member is working on, so that the most competent person can provide immediate assistance in overcoming any obstacles. 

Simplified documentation 

We often encounter the reflex in a waterfall project to document the testing phase tasks as precisely as possible, so that each phase can be reproduced even afterward. Of course, this has its advantages, but it is undeniably a time-consuming approach. From this perspective, agile testing is often criticized for neglecting documentation. However, this is not the case. According to one of the core principles of Agile, the work done is more important than detailed documentation. We document what is useful and practical, and we do so concisely. This responsibility falls on everyone working with information related to testing: be it developers or testers. 

Client feedback during the development process 

One of the main advantages of agile software testing is the same as that of the methodology itself: the client is present at the earliest stages of the development process or even continuously, allowing them to see the implementation of customer requirements close to the planning tasks. This enables them to provide immediate feedback before investing too many resources into a potentially flawed idea.  

The process of agile software testing 

The principles and practices of agile software testing differ from traditional testing. We examined its theoretical aspects in the previous chapter. Now, let's explore what needs to be considered in practice to successfully implement agile testing. There are essential tasks necessary for successful testing, and often, testers are best equipped with the information needed to perform these tasks most effectively during the course of their work.  

1. Impact analysis: forming business thinking related to the software; identifying boundary conditions, risks; architectural considerations. 

2. Test planning: it is necessary to determine which testing levels we apply and how we implement them: unit and component testing; continuous and prototype testing; business and usability tests, as well as checking non-functional requirements, are all essential quality assurance criteria for the releasable software.

3. Daily stand-up meeting: The tester is as much a part of the team as anyone else, so they participate in daily communication: a short, time-bound and agenda-focused morning stand-up meeting can prevent the development of idle periods or persistent blocking factors. 

4. Feedback: It may seem trivial, but it cannot be emphasized enough – we test to find defects. Whether it's an improper implementation or a misunderstood business requirement, it needs to be rectified as soon as possible, ideally while the development team is still working on the same task as the testers. 

5. Verification: Before the product is ready for users to take possession, every task and documentation must be completed. Often, testers are the most familiar with the software's operation, so it is advisable to train or educate them in relation to the release for those who will support or use the software. 

Frequently Asked Questions 

What does agile mean? 

A software development methodology that aims to deliver the highest value through short iterations, continuous customer involvement, and adaptation. 

What is agile software testing? 

Unlike traditional testing, agile software testing becomes part of the methodology through collaboration with developers, essential documentation, and flexible work organization. 

What are the benefits of agile software testing? 

The main advantage of its introduction and application is that it eliminates idle time for the testing team by working continuously with the development team, ensuring that we can release software that adds value to the customer as soon as possible. 

What are the steps involved? 

The steps of agile testing are impact analysis, test planning, daily stand-up meetings, feedback, and verification.
