Manual testing & Automation Testing

Table of Contents

Manual testing is the main testing phase that’s closest to software development. It evaluates the behavior of the website or application developed through a step-by-step assessment based on the requirement specification analysis record. The core objective of manual testing is to ensure that the product works as per the requirement specification documents and that no defects or functional defects exist.

Reasons why manual testing will always be needed

Manual testing is a preferred choice in several scenarios. Let’s look at areas where automation is not an option, and manual testers are better suited.

  1. Smaller projects: Constructing and deploying automated testing systems is resource intensive. The overhead of automated testing is much higher than manual testing. Therefore, manual testing is the only economically feasible option for smaller projects.
  2. Automation is expensive: We already  wrote that why automated testing is not feasible for smaller projects, but for small organizations with budget constraints, it might not be an option even for larger projects. Manual testing offers an alternative to escape automated test methods’ high expenses and maintenance costs.
  3. User experience: A machine can never fully emulate human behavior. This is why for user experience testing; we need manual testers who can imitate such behaviors and analyze the software product according to the needs and requirements of the end users. Manual testing will always be needed for higher UX. Unless we invest in a highly trained AI solution, such a level of user experience testing is impossible with automation.
  4. Comprehensive and detailed testing: In automated testing, we have fixed and predetermined procedures that evaluate the software’s functioning and behavior according to preset rules. While the process is much quicker, the absence of any customization can result in minute defects getting ignored. As an additional layer of security, manual testing is required to remove any such bugs.


“Balancing Act: The Symbiotic Relationship of Manual and Automated Testing in Software Quality Assurance”


In the ever-evolving landscape of software development, the quest for faster releases and higher quality has led to the rise of automated testing. However, amidst the automation revolution, the importance of manual testing remains a cornerstone in achieving comprehensive software quality assurance. Let’s explore the symbiotic relationship between manual and automated testing and how this balance is crucial for delivering robust and user-friendly applications.


The Human Touch in Manual Testing:

While automated tests excel at repetitive and predictable tasks, they may struggle to mimic the unpredictable nature of real-world user interactions. Enter manual testing, where human testers bring their intuition, creativity, and domain expertise to the table. Manual testing is invaluable for exploratory testing, user experience assessment, and identifying complex issues that automated scripts might overlook.


User-Centric Evaluation:

One of the key strengths of manual testing lies in its ability to evaluate the software from the end user’s perspective. Testers can assess the user interface, intuitiveness, and overall user experience – aspects that are challenging for automated tests to measure accurately. By putting themselves in the user’s shoes, manual testers play a pivotal role in ensuring the application meets not just functional but also usability requirements.


Early Feedback for Agile Development:

In the agile development era, where rapid iterations are the norm, manual testing provides early feedback. Testers can uncover issues at the early stages of development, allowing for quick resolution and preventing potential bottlenecks later in the development cycle. This iterative feedback loop promotes a more agile and responsive development process.


Cost-Effectiveness in Certain Scenarios:

For smaller projects or organizations with limited resources, manual testing can be more cost-effective. Setting up and maintaining an automated testing framework requires an upfront investment, making it less practical for projects with constrained budgets. Manual testing, in such cases, offers a pragmatic and resource-efficient approach to ensure software quality.


Manual Testing as a Precursor to Automation:

Manual testing often serves as a foundation for the creation of automated test cases. Testers identify repetitive tasks and scenarios suitable for automation. By starting with manual tests, teams can strategically plan their automation efforts, focusing on areas that provide the most significant return on investment.


Striking the Right Balance:

In the dynamic landscape of software development, the key lies in finding the right balance between manual and automated testing. While automated tests excel at regression testing, repetitive tasks, and large-scale data validation, manual testing adds the human touch needed for exploratory testing, usability assessment, and adapting to evolving project requirements.


In conclusion, the relationship between manual and automated testing is not a competition but a collaboration. Each approach has its strengths, and together they form a comprehensive testing strategy that ensures software meets the highest standards of quality. As we navigate the future of software development, let’s embrace the power of this dual approach, leveraging both the precision of automation and the human insight of manual testing to deliver exceptional software experiences.
