The procedure of manual testing

Understanding the Requirements:

For successful QA manual testing, software testers must comprehend the software’s necessities, such as its intended functionality. This understanding guides testers on what needs to be tested and which sections require scrutiny. It is crucial to gather this information beforehand because the primary goal in software testing is to approach the software as closely as possible, striving for an error-free and bug-free application.

Some essential tasks in requirement analysis include:

  • Identifying test conditions
  • Reviewing the test basis (the vital information on which test cases rely, like architecture, requirements, design specifications, product risk analysis, and interfaces)
  • Planning the tests
  • Designing the test environment setup and determining the necessary tools and infrastructure

Test Plan Creation:

Test planning involves creating a document outlining the overall approach and test objectives. This process includes evaluating the test basis, establishing test conditions based on item analysis, crafting test cases, and designing the test environment. Clear exit criteria or completion conditions should be defined to indicate when testing, at any stage, is concluded.

Key tasks in test plan creation encompass:

  • Identifying risks, scope, and testing objectives
  • Verifying necessary test resources, such as test environments and personnel
  • Scheduling test analysis and design tasks, test execution, implementation, and evaluation

Writing Test Cases:

Once the requirements are understood, it’s time to develop and prioritize test cases. Test cases serve as reference guides for QA engineers, providing instructions and steps to test specific scenarios and functions within the software application.

Conducting the Tests:

After setting up the testing environment and creating test cases, it’s essential to commence testing. This fundamental testing process involves actual work, where each test is marked as skipped, failed, or passed. During manual tests, it is crucial to maintain detailed notes on events leading to test failures, as these metrics are valuable for future planning.

Defect Logging:

This step involves identifying defects in the application under test by testing or gathering feedback from customers. This information is used to create updated versions of the product, addressing and fixing the identified flaws.

Defect Fix and Further Verification:

When software developers make significant code changes and confirm these modifications, the bug status is changed to ‘Fixed,’ and the issues are transferred to the QA manual testing team. At this stage, testers perform re-verification and testing of the modified code.

Grey Box Testing: Grey Box Testing strikes a balance between black box and white box testing. Testers conducting grey box testing have partial knowledge of the internal code, utilizing this information to design insightful test cases. Unlike white box testing, where testers possess complete knowledge, grey box testers have limited insights. This method allows for comprehensive test coverage by focusing on specific areas where partial knowledge is most valuable. Grey box testing is particularly useful when combining the benefits of both black box and white box testing methodologies without exposing the entire codebase.

Exploratory Testing: Exploratory Testing stands as a dynamic and unscripted approach where testers explore the software without predefined test cases. Relying on intuition, creativity, and domain knowledge, testers navigate the application as end-users would. The goal is to uncover defects, issues, and unexpected behaviors by interacting organically with the software. This method’s adaptability enables testers to adjust their approach based on real-time findings. Exploratory testing encourages thinking beyond the obvious, making it effective for identifying complex and subtle defects often overlooked in scripted testing scenarios.

Ad-hoc Testing: Ad-hoc Testing represents a spontaneous and informal testing method where testers assess the software without adhering to predefined test cases or requirements. Testers rely on their expertise, experience, and domain knowledge to identify potential issues and defects. This method is especially useful in time-sensitive situations, such as tight deadlines or urgent bug-fixing scenarios, where creating formal test cases is not feasible. Despite lacking structured documentation, ad-hoc testing is invaluable for promptly identifying critical issues, allowing for immediate corrective actions.

In summary, these manual testing methods offer diverse approaches to evaluating software applications. Each method is tailored to specific testing objectives and constraints, ensuring thorough testing coverage and the delivery of high-quality and reliable software products.
