What is Software Testing?

Posted by

Hi Everyone,

This is ravi and today, we will discuss manual testing. Manual software testing is a vital process in software development, involving the manual execution of test cases to identify and resolve defects in software applications. This guide covers the essentials of manual testing, its significance, different types, steps involved, best practices, and useful tools.

Understanding Manual Software Testing.

Manual software testing involves human testers executing test cases without automation tools. Testers simulate end-user behavior to detect bugs and issues within the software. This method relies on the tester’s expertise and intuition to uncover defects that automated tests might miss.

Importance of Manual Testing

Manual testing is essential because it enables testers to evaluate the software from a user’s perspective, detecting usability issues and bugs that automated tests may overlook. It is flexible, allowing testers to adapt quickly to changes in software requirements and features. Manual testing is particularly important for exploratory testing, where the tester’s insight and intuition help uncover unexpected defects, ensuring the application is intuitive and user-friendly. This approach also validates the software’s overall look and feel, ensuring it meets end-user expectations.

Manual testing remains crucial for several reasons.

a. Human Insight: Human testers can identify user experience issues and subtle bugs that automated tests might overlook.
b. Flexibility: Manual testing allows for quick adaptation to changes in software requirements and new features.
c. Exploratory Testing: This type of testing, where testers explore the application without predefined cases, is best suited for manual execution.

Types of Manual Testing

Manual testing is the process of manually executing test cases without automation tools to identify defects in software applications. It involves human testers checking the functionality, usability, and overall performance of the software by simulating end-user interactions.

a. Black Box Testing: This method involves evaluating the software’s functionality without any knowledge of its internal code or logic. Testers validate the inputs and outputs to ensure the application meets the specified requirements.

b. White Box Testing: This technique requires testers to have an understanding of the internal structure and code of the application. It involves testing the internal operations to ensure they function as intended.

c. Unit Testing: This type focuses on examining individual components or modules of the software to verify that each part operates correctly in isolation.

d. Integration Testing: This approach tests the interactions between different modules or components of the software. The goal is to identify any issues that occur when these units are combined.

e. System Testing: This comprehensive testing method assesses the complete and integrated software application to ensure it meets the defined requirements and performs as expected.

f. Acceptance Testing: Conducted to determine if the software is ready for delivery, acceptance testing checks if the application meets the business requirements and can be used by the end-users. This type of testing is often performed by clients or end-users.

Steps in Manual Testing

Manual testing is the process where testers manually execute test cases without using automation tools. It involves understanding the requirements, planning, developing test cases, setting up the test environment, executing the tests, reporting defects, and finalizing the testing process.

a. Requirement Analysis: Understand and review the software requirements and specifications to ensure all aspects are covered.

b. Test Planning: Create a test plan that outlines the testing objectives, scope, resources, schedule, and deliverables. Define the criteria for starting and ending the testing process.

c. Test Case Development: Develop detailed test cases and test scripts that cover all functionalities and scenarios based on the requirements.

d. Environment Setup: Configure the testing environment with the necessary hardware and software to execute the test cases.

e. Test Execution: Execute the test cases manually, documenting the results and any discrepancies or defects found during the process.

f. Defect Reporting and Tracking: Log defects found during testing into a tracking system with detailed information, such as steps to reproduce, severity, and screenshots.

g. Test Closure: Complete the testing process by evaluating if the testing objectives were met. Prepare a test summary report and gather metrics for future reference.

Performing Manual Testing

Manual testing involves a tester manually executing test cases without using automated tools. It includes understanding the software, creating and executing test cases, documenting defects, and verifying fixes through retesting and regression testing.

a. Understand the Application: Begin by thoroughly reviewing the software’s requirements, specifications, and user documentation to understand its intended functionality and user experience.

b. Create Test Cases: Develop detailed test cases that outline specific conditions and steps to test various aspects of the software. These should cover both typical use cases and edge cases to ensure comprehensive coverage.

c. Execute Test Cases: Manually run the test cases, following the specified steps and comparing the actual results with the expected outcomes. Note any discrepancies or unexpected behaviors.

d. Report Bugs: Document any defects found during testing in a bug tracking system. Include detailed information such as steps to reproduce the issue, the severity of the defect, and any relevant screenshots or logs.

e. Retest and Regression Testing: After developers address reported issues, retest the affected areas to confirm the fixes. Conduct regression testing to ensure that recent changes have not introduced new issues in previously working functionality.

Best Practices for Manual Testing

Manual testing involves testers manually executing test cases to identify defects without using automated tools. It includes understanding requirements, planning and developing test cases, executing them, reporting defects, and verifying fixes through retesting and regression testing.

a. Start Early: Begin testing as soon as possible in the development lifecycle to catch defects early and reduce the cost and effort required to fix them later.

b. Comprehensive Documentation: Keep detailed records of test cases, results, and defect reports. This helps ensure thorough testing and makes it easier to replicate and address issues.

c. Understand Requirements: Ensure you fully understand the software requirements and specifications to create effective and relevant test cases.

d. Prioritize Testing: Focus on high-risk areas and critical functionalities first. Prioritize test cases based on the potential impact and likelihood of defects.

e. User Perspective: Test the application from an end-user’s point of view to identify usability issues and ensure the software meets user expectations.

f. Exploratory Testing: In addition to planned test cases, conduct exploratory testing to discover unexpected defects by freely exploring the application’s functionalities.

g. Update Test Cases Regularly: Keep test cases up-to-date with any changes in the application to ensure ongoing relevance and coverage.

h. Use Defect Tracking Systems: Implement a defect tracking system to log and manage defects efficiently, ensuring they are documented, assigned, and resolved systematically.

i. Collaborate with Developers: Maintain open communication with developers to understand the application better and resolve defects more efficiently.

j. Continuous Learning: Stay informed about the latest testing techniques, tools, and industry trends to improve testing skills and adopt new best practices.
