Manual testing is a fundamental yet essential process in software development where testers manually execute test cases without the use of automation tools. Despite advancements in automation, over 30% of global testing efforts are still carried out manually, according to industry research.
As applications grow in complexity, many organizations face challenges, such as time-consuming test execution, lack of test coverage, and difficulty scaling manual efforts, leading to a 40% increase in release cycle times for teams that rely solely on manual testing.
Why is Manual Testing Important?
Manual testing plays a key role in detecting usability issues, assessing the user experience, and ensuring that the application behaves as expected. It is especially valuable in the following cases:
Exploratory Testing: Manual testing allows testers to explore the application in an unstructured way, discovering issues that may not be identified through automated scripts.
Ad-hoc Testing: Testers can perform ad-hoc testing, where they spontaneously evaluate the application without predefined test cases, which helps catch unique bugs.
Usability Testing: Automation tools can't assess user-friendliness or UI design effectively. Manual testers can evaluate how intuitive and pleasant an application is for users.
What are the Key Principles of Manual Testing?
Test Early and Often: Start testing as soon as possible to catch issues before they evolve into more significant problems. Early testing also helps in aligning the application with user requirements.
Clear Test Cases: Write well-defined and simple test cases that describe the steps to execute and the expected outcomes. This ensures clarity and reproducibility in testing.
Bug Tracking and Reporting: When issues are found, documenting them is essential. Bug tracking tools like Jira, Bugzilla, and Trello are frequently used in manual testing to organize and manage bugs.
What are types of Manual Testing?
Smoke Testing: A quick, high-level testing approach to ensure the basic functionality of the application works.
Sanity Testing: Performed after changes or fixes to ensure that a specific issue has been resolved without affecting other parts of the application.
Regression Testing: Ensures that recent code changes have not adversely affected existing functionality.
User Acceptance Testing (UAT): Conducted by the end-users to ensure that the application meets their needs and performs as expected in real-world scenarios.
How to Perform Manual Testing (Step-by-Step)
Requirement Analysis: Start by understanding the requirements and objectives of the application. This will guide you in creating relevant test cases.
Test Planning: Outline the scope of testing, identify the areas to be tested, and choose the type of manual testing needed.
-
Test Case Development: Write test cases that include the steps to be followed and the expected results. For example, a simple test case for a login form might be:
- Step 1: Navigate to the login page. - Step 2: Enter valid username and password. - Expected Result: User successfully logs in. Test Execution: Execute the test cases manually by interacting with the application as an end-user would. Carefully observe and note down any deviations from the expected results.
Defect Reporting: If any issues are found, they should be documented in a bug report, including the steps to reproduce, severity, screenshots (if applicable), and expected versus actual results.
Test Closure: After testing is complete, review the test results and create a summary report. Discuss the findings with the development team and other stakeholders.
Tools that Complement Manual Testing
Even though manual testing is performed without automation, various tools can still support the testing process:
TestRail: A test management tool to organize test cases, track execution, and report results.
Jira: A popular tool for bug tracking and project management, useful for organizing and reporting defects during manual testing.
Zephyr: Integrated with Jira, Zephyr allows for seamless test case management and reporting.
What are the Challenges with Manual Testing?
Manual testing, while essential in certain scenarios, presents several challenges that can impact the efficiency and effectiveness of the testing process. Some of the most common challenges include:
Toil Work: The never-ending loop of repetitive tasks can make testing feel like a grind, leading to burnout and missed bugs.
Scalability: As your software grows, so does the mountain of test cases. Manual testing struggles to keep pace, risking gaps in coverage.
Limited Perspective: Manual testers may have a limited perspective based on their understanding and experience. This can lead to missed edge cases or scenarios that automated tools might catch.
How to Overcome the Challenges?
While these challenges can be daunting, there are strategies that testers and teams can adopt to mitigate them:
Reducing Toil Work: Free up your testers by automating repetitive tasks. This keeps the team fresh and focused on the critical issues that need human insight.
Enhancing Scalability: Integrate automated testing to handle the heavy lifting as your software grows. Prioritize high-impact areas and adopt continuous testing to stay ahead of the curve.
Broadening Perspective: Mix up your testing team, encourage cross-functional collaboration, and use analytics to uncover what you might be missing. Fresh perspectives can make all the difference. Additionally, using test management tools that incorporate analytics can help identify gaps in coverage and areas that need more attention.
What is the Future of Manual Testing?
As applications become more user-centred, there will always be a need for human observation, creativity, and intuition. The future of manual testing lies in complementing automation to enhance software quality.
In response to these challenges, AI-driven testing tools like Keploy have emerged, offering automation capabilities that can significantly reduce the burden of manual testing.
