What is manual testing?

Manual testing is a method of software testing where testers manually execute test cases without the use of automation tools. Testers carefully explore the application’s functionalities, testing various scenarios and inputs to ensure the software behaves correctly. This process involves creating test cases, executing them, and documenting the results. Manual testing is valuable for ad-hoc and exploratory testing, as well as scenarios where automation is not practical.

What different types of manual testing are there?

There are various types of manual testing, including:

• Black Box Testing: Testing the software’s functionality without knowledge of its internal code or structure.
• White Box Testing: Testing the software with knowledge of its internal code and structure.
• Functional Testing: Testing the software’s functionality against specified requirements.
• Non-Functional Testing: Testing aspects such as performance, usability, and security.
• Regression Testing: Testing to ensure that new changes have not adversely affected existing functionality.
• Exploratory Testing: Testing where testers explore the software to find defects without following a predefined test plan.
• User Acceptance Testing (UAT): Testing performed by end users to ensure the software meets their requirements.

What are the distinctions between alpha testing and beta testing?

Aspect	Alpha Testing	Beta Testing
Conducted by	Internal QA team or developers	Selected group of end users or external testers
Location	Conducted at the development site	Conducted at the client’s location or in a real-world environment
Focus	Identifying bugs and issues before release	Ensuring user acceptance and gathering feedback
Features Tested	Typically not all features are tested	All features are tested
Testing Approach	Includes white box and black box testing	Primarily involves black box testing

What are the different levels of manual testing?

The stages of manual testing encompass several key phases:

• Unit Testing: This phase involves testing individual components or units of the software to ensure they function correctly.
• Integration Testing: Here, the focus is on testing the interactions between integrated components to ensure they work together seamlessly.
• System Testing: This phase involves testing the entire system as a whole to verify that it meets specified requirements and functions as intended.
• User Interface (UI) Testing: This testing phase focuses on the graphical user interface (GUI) of the software to ensure it is user-friendly and functions correctly.
• Acceptance Testing: This is the final phase of testing before the software is released to end users. It involves testing the software to ensure it meets user requirements and expectations.

What is a testbed in manual testing?

In manual testing, a testbed is the environment or setup used for conducting testing activities. It includes hardware, software, and network configurations that simulate real-world usage. The testbed should replicate conditions where the software will be deployed. It also includes tools and resources like test cases, data, and testing tools.

How do verification and validation differ in the context of testing?

Verification is the process of confirming that software products align with the established implementation steps from the previous phase of the development cycle. It ensures that the development process adheres to predefined procedures. On the other hand, validation evaluates the software throughout the development process or at its culmination to verify if it meets the specified requirements set forth by stakeholders, ensuring the final product meets the desired standards and functionalities.

Could you elaborate on the Software Testing Life Cycle (STLC)?

The Software Testing Life Cycle (STLC) is a series of steps that outlines the testing process. It starts with requirement analysis, followed by test planning, test case development, and setting up the test environment. The next steps include executing the test cases, tracking defects, and performing regression testing. Test reporting is done to document the results, and finally, the testing phase is closed. The STLC ensures that software is thoroughly tested, defects are identified and fixed, and the software meets quality standards before release.

What are the advantages of manual testing?

Manual testing has several advantages:

• Cost-Effective: It is more economical as it does not require expensive automation tools or resources, making it suitable for small-scale projects or situations where automation is not feasible.
• Flexibility: Manual testing allows testers to quickly adapt to changes in requirements or user feedback, making it well-suited for agile development environments.
• Exploratory Testing: Testers can explore the software and identify unexpected issues that may not be covered by automated tests.
