Understanding the Consequences of Non-Incremental Software Releases in Quality Assurance

We’ve all been there: a major software release drops and suddenly you’re overwhelmed with bug reports and unhappy customers.

It’s a common scene, a direct result of the fallacy that non-incremental releases are more efficient.

What if I told you that after eight and a half years in the trenches, I’ve discovered that embracing incremental releases not only reduces the number of post-release bugs but also increases team productivity?

In this blog post, we’ll delve into the cause and effect of not releasing incrementally on QA, with a particular emphasis on how it impacts testing processes, testing standards, and the pivotal role of innovative tools like LambdaTest. We’ll also explore how critical skills in communication and technical proficiency are paramount in dealing with the challenges presented by non-incremental releases.

The Impact on QA Testing

In the dynamic realm of software development, quality assurance (QA) stands as the bedrock for delivering impeccable software products. A central tenet of robust QA is the practice of releasing software updates incrementally – a strategy that involves the regular rollout of smaller, manageable updates instead of waiting for a single, massive release. 

Diverging from this established practice and opting for a non-incremental rollout can introduce a host of challenges, such as:

  • Bottlenecks in Testing: Non-incremental releases can lead to significant testing bottlenecks. When a substantial amount of new features and changes are bundled together, QA teams face a daunting volume of work that must be completed within a limited timeframe, increasing the risk of vital issues slipping through the cracks. 
  • Complexity of Testing: The absence of incremental releases introduces complexity to the testing process. In non-incremental development, a single, colossal release typically includes numerous new features, changes, and improvements. These changes can be interrelated, and any modification to one component can impact others. This necessitates the creation of intricate and extensive test cases to cover these multiple conditions and requirements, taking into account the dependencies. However, this intricate testing process can make it more challenging for QA professionals to ensure comprehensive coverage. As a result, critical issues may go undetected, ultimately affecting the software’s quality and reliability.
  • Procrastination of Testing: Delaying testing until the project’s final stages can create unwarranted pressure on QA teams. In such cases, QA professionals might be forced to rush their testing efforts to meet tight deadlines, compromising the thoroughness of testing and increasing the risk of missing vital defects.The time spent waiting on releases can also cause general frustration for testers.
  • Resource Allocation Challenges: In non-incremental development, the sudden surge in testing requirements towards the end of the project can strain QA resources. QA teams may struggle to allocate adequate manpower, testing environments, and tools within a limited timeframe. This resource crunch can lead to testing inefficiencies and hinder the ability to perform comprehensive testing. Additionally, it can result in overworked QA professionals, affecting their performance and morale.

Effects on Testing Standards

Non-incremental software releases have a significant impact on testing standards. Unlike their incremental counterparts, these types of releases may delay the detection of issues and defects, leading to potential risks and challenges in the later stages of development.

These impacts can include:

  • Lack of Standardization: In non-incremental development, maintaining standardized testing practices becomes a formidable task, making it challenging to apply consistent testing standards across different phases of the project. The absence of a structured testing framework can lead to inconsistencies in the quality and coverage of testing efforts. This absence of standardisation can significantly impede the capacity of QA professionals to maintain software quality, potentially leading to a departure from established best practices.
  • Efficiency and Quality: Incremental releases enable QA professionals to adhere to well-defined testing standards and best practices throughout the development process, ensuring that the software’s quality remains consistently high. In non-incremental development, the need for expedited testing to meet deadlines can compromise the quality and thoroughness of the work, potentially impacting the final product’s quality and reliability.
  • Alignment with Industry Standards and or Company Standards: Standardised testing practices often align with industry standards and compliance requirements or, specifically, your organization’s standards. Non-incremental releases can make it challenging to demonstrate compliance with these standards, potentially leading to legal or regulatory issues for the organization. QA professionals must navigate complex compliance issues in the absence of incremental testing, which can be time-consuming and risky.
  • Risk Management: Standardised testing practices often include risk management protocols that help identify and mitigate potential risks early in the development process. In non-incremental releases, the rush to complete testing can result in a lack of thorough risk assessment. This increases the risk of critical issues remaining undiscovered until the product is in the hands of end-users, which can have financial and reputational consequences.

Role of Testing Tools in QA to Avoid These Consequences 

Understanding the potential pitfalls of non-incremental software releases underscores the critical role of testing tools in QA. These tools serve as a safeguard, helping to mitigate risks and ensure adherence to established best practices. 

They facilitate comprehensive and rigorous testing procedures, which are crucial in maintaining software quality and preventing the negative consequences associated with deviation from incremental rollouts. Let’s take a deeper look into this:

  • Efficiency and Productivity: Testing tools play a pivotal role in enhancing the efficiency and productivity of QA professionals in testing scenarios. These tools can automate various aspects of the testing process, such as test case execution and reporting. By automating repetitive tasks, testing tools allow QA teams to save valuable time and resources. This time savings can be redirected towards more in-depth testing, exploring edge cases, and resolving critical issues, ultimately leading to higher product quality.
  • Integration and Collaboration: Testing tools often come with features that facilitate integration with other testing and project management tools. This integration allows seamless collaboration between QA professionals, developers, and stakeholders. It enables real-time sharing of testing results, issue tracking, and collaborative problem-solving. In non-incremental development, where close collaboration is crucial due to the complexity of releases, testing tools such as these, also used at Polymorph, help ensure that all team members are on the same page, resulting in a more streamlined and effective testing process. 
  • Test Data Management: Testing tools offer capabilities for effective test data management. In non-incremental releases, where the volume of data and scenarios can be extensive, having tools that enable the creation, provisioning, and management of test data is crucial. This ensures that QA professionals can adequately test the software under various data conditions, leading to more reliable results and improved software quality.
  • Performance Testing: Many testing tools also provide performance testing features, allowing QA teams to assess how the software performs under different conditions, such as heavy loads or high user traffic. In non-incremental releases, where the entire system is released at once, performance testing is critical to identify and address potential bottlenecks or scalability issues that might arise when the software is in the hands of users. Releasing incrementally allows testers to be able to test APIs individually before they are integrated into the wider systems, thereby mitigating the risk and identifying these bottleneck areas that can be addressed early on in the development process instead of later on. 

Skills for Mitigating Issues in Non-Incremental Releases

Finally, in dynamic non-incremental release environments, QA professionals play a pivotal role in ensuring the quality of custom software. Let’s explore the key skills vital for success in this context:

  • Adaptability and Flexibility: QA professionals working in non-incremental release environments must be highly adaptable and flexible. Sudden changes or last-minute alterations are not uncommon in such scenarios. Being able to quickly adjust test plans, strategies, and priorities is crucial to maintaining the quality of the software. Adaptability ensures that QA teams can respond effectively to unexpected challenges and shifting project dynamics.
  • Risk Assessment and Management: Effective risk assessment and management skills are essential for QA professionals. They should be adept at identifying potential risks and understanding the implications of those risks on the project. By proactively assessing and managing risks, QA teams can prioritize their efforts, allocate resources efficiently, and focus on the most critical areas, thereby reducing the likelihood of major issues surfacing late in the development process.
  • Attention to Detail: Attention to detail is a foundational skill for QA professionals in any context, but it becomes even more critical in non-incremental releases. The complexity of such releases often means that small details can have significant impacts on the final product’s quality. QA professionals must meticulously examine every aspect of the software, leaving no stone unturned to ensure that all issues, regardless of their size, are discovered and addressed.There is also an approach of “Shift-Left”, coined by Larry Smith in 2001, testing where the time of testers can be spent on “testing” designs and documentation. This solves issues or defects before the development has even begun.
  • Problem-Solving and Troubleshooting: Non-incremental releases can present unique and challenging issues. QA professionals need strong problem-solving and troubleshooting skills to identify the root causes of defects, determine their impact on the software, and develop effective strategies for resolution. Quick thinking and the ability to find innovative solutions are invaluable in resolving unexpected issues.
