We live in a golden age in which technology permeates every aspect of our life. This is especially true now that “Artificial Intelligence” has become an integral part of the industry. Artificial intelligence (AI) is a technology that replicates intelligence in machines by enabling them to think, act, and mimic human responses. From virtual assistants like Alexa, Google Home, and Siri to assisting in developing new revolutionary innovations like autonomous vehicles, blockchain, and cryptocurrencies, AI is ubiquitous.Software testers who have relied on manual testing throughout their careers are becoming increasingly worried about their future. With the current trend of applying automation and AI to almost any imaginable work task, many testers believe it’s just a matter of time before their roles get replaced by computers. If you visit any online forum or community, you’re bound to see questions like:
“Is manual testing dead?”
“Should I forget manual testing and focus on test automation?"
“Is it even worth searching for manual testing jobs nowadays?"
Automated tests are excellent for repetitive and predefined tasks, but they lack the human intuition and creativity necessary to identify unexpected issues. Manual testers can explore the software from a user's perspective, intuitively identifying edge cases and usability issues that automated tests might overlook.
Exploratory testing is a manual testing approach where testers actively explore the software, simultaneously learning, designing, and executing tests. This approach is invaluable for discovering unknown issues, understanding complex features, and improving the overall quality of the software. Exploratory testing relies on the tester's expertise, curiosity, and ability to think on their feet.
Manual testing is essential for evaluating the user experience. Testers can assess the intuitiveness, accessibility, and overall satisfaction of the application. They can provide qualitative feedback on the look and feel of the interface, the ease of navigation, and any potential frustrations a user might encounter. This feedback is crucial for ensuring that the software meets user expectations and provides a positive experience.
In Agile and DevOps environments, requirements can change rapidly. Manual testers can quickly adapt to these changes, testing new features or modifications without the need for extensive rework of automated test scripts. This flexibility ensures that testing keeps pace with development and that issues are identified early in the process.
Some test scenarios are too complex to automate effectively. These scenarios may involve intricate user interactions, multiple dependencies, or dynamic data inputs that are challenging to replicate with automated tests. Manual testers can handle these complex scenarios, ensuring comprehensive test coverage.
Manual testers can provide immediate feedback to developers, helping to quickly identify and resolve issues. This real-time communication fosters collaboration and ensures that critical defects are addressed promptly, reducing the overall development time and improving software quality.
Manual testing requires significant time and effort, especially for large and complex applications. Each test case must be executed individually, and repetitive tasks can become particularly labor-intensive.
Human testers are susceptible to mistakes. Errors can occur in test case execution, data entry, or result interpretation, leading to missed defects or inaccurate test results.
Different testers may approach the same test case differently, leading to inconsistencies in test execution and results. This variability can affect the reliability of the testing process.
As the application grows in complexity and size, the volume of test cases increases, making manual testing less scalable. Managing and executing a large number of test cases manually becomes impractical.
Manual testing may not cover all possible scenarios and edge cases, leading to gaps in test coverage. This limitation is particularly problematic for large applications with numerous interactions and dependencies.
Regression testing, which involves re-testing previously tested features after changes, is challenging and time-consuming when done manually. Ensuring that changes do not introduce new defects requires extensive and repetitive testing.
Manual testing can sometimes suffer from inadequate documentation and reporting. Without detailed records, it becomes challenging to track test coverage, progress, and results.
Despite all the advantages that test automation provides to organizations, that doesn’t mean it’s a silver bullet that will replace all other testing processes. Automation is just a piece of the software quality puzzle and shouldn’t be the only testing method in place for validating applications. Manual testing still holds immense value for ensuring your company delivers a high-quality customer experience by covering what automation can’t.
Manual testers have plenty of advantages over automation. They can apply their vast experience with the product and their industry to improve what they’re testing. Manual testers also have an understanding of human behavior that computers simply don’t have and can provide further insight into improving the software. Additionally, intuition plays a significant role in testing by covering scenarios others have overlooked, which automation cannot do on its own. These are just a few advantages a human tester has over its computerized counterpart.
Test automation only does what you tell it to do, and, in return, it tells you whether those expected outcomes are still valid. While this functionality—known as regression testing—is ideal for ensuring that recent changes haven’t affected an application, it’s an inflexible process that can let bugs slip in undetected. Allowing testers to explore the application without any guidelines, also known as exploratory testing, is where manual QA shines. The slower, meticulous pace of validating an application with complete freedom uncovers bugs or usability issues that lead to an improved product.
Even with all the advantages that the human touch provides regarding software testing, there’s no denying that automation is here to stay. Expect companies to continue adopting test automation and fueling its exponent growth. The current AI trend will further accelerate these advancements as well. As those tools improve, more organizations will jump on the automation bandwagon and take advantage of its benefits.
Does that mean that manual testing is going the way of the dinosaur and become a relic of the past? Not at all. There’s still a spot for manual testing in today’s software development environment. Automation cannot cover every area that helps boost the stability of an application. Unless technology improves much faster than anyone expects, organizations will still need non-automated testing if they want to deliver first-rate products.
However, that doesn’t mean manual testers can or should continue doing what they’ve been doing throughout their careers. The future of manual testing lies in adapting and growing alongside technological advances. Instead of disregarding automation, manual testers must integrate it into their skillset. That’s not to say all testers need to migrate toward automated testing. Instead, they should rely on their strengths—critical thinking, intuition and life experience—while using automation to complement their skills.Learning how to use and work effectively with automated testing tools is an excellent starting point for manual testers. While it sounds daunting, especially for testers with zero coding experience, the good news is that the barrier to entry with these tools is as low as ever. Many testing tools nowadays offer ways to leverage automation without needing to learn required skills for test automation, like understanding how to program and debug code.
As AI and machine learning technologies continue to advance, manual testers will leverage these tools to enhance their testing processes. AI-driven test automation tools will offer intelligent test case generation, defect prediction, and self-healing capabilities, augmenting the capabilities of manual testers and improving the overall efficiency and effectiveness of testing efforts. Manual testers will collaborate with AI systems to uncover complex issues and provide valuable context and insights that drive continuous improvement.
In the rapidly evolving landscape of modern software development, manual testers must embrace a mindset of continuous learning and adaptation. They must stay abreast of the latest trends, technologies, and methodologies in testing, and continuously enhance their skills to remain relevant in a highly competitive environment. By investing in professional development and embracing new challenges, manual testers will position themselves as invaluable assets to their organizations and key drivers of innovation and quality.
In conclusion, despite the rapid advancements in automation and AI within software development, manual testing remains an indispensable component of a robust quality assurance strategy. It offers unique human insights, intuitive problem-solving, and the ability to evaluate user experience in ways that automated tests cannot match. By integrating automation tools to handle repetitive tasks and focusing manual efforts on high-value activities like exploratory testing and UX evaluation, manual testers enhance overall software quality. As technology evolves, the complementary relationship between manual and automated testing ensures that organizations can deliver user-friendly, reliable, and high-quality applications, maintaining the critical human touch in a highly automated world.
