3. Distinguish between Manual Testing and Automated Testing.

Aspect	Manual Testing	Automated Testing
Execution Method	Human testers manually execute test cases, interacting directly with the software to observe and record outcomes.	Test cases are executed through automated testing tools or scripts, simulating user actions and validating expected outcomes without human intervention.
Speed and Efficiency	Typically slower and less efficient, especially for extensive or repetitive testing endeavors, due to human involvement in test execution and analysis.	Offers faster and more efficient testing, particularly for repetitive tasks and regression testing, as tests can be executed rapidly and repeatedly without manual oversight.
Repeatability	Test case execution may vary due to human error or inconsistency, making it challenging to repeat tests exactly as before.	Ensures repeatability and consistency, as automated tests consistently execute the same steps and yield predictable results across test runs.
Human Judgment	Relies on human judgment, intuition, and domain knowledge to identify defects and evaluate software quality, allowing testers to adapt their approach based on observations.	Lacks human judgment and creativity, following predefined scripts and potentially missing defects that require human insight or intuition to identify.
Initial Setup and Maintenance	Requires minimal setup, with test cases created and executed without significant investment in tools or infrastructure.	Involves initial setup and ongoing maintenance of test scripts and frameworks, which can be time-consuming and resource-intensive, particularly for complex applications.
Cost	Lower upfront costs as it doesn’t necessitate investment in automation tools or infrastructure, though it can become costly over time due to labor-intensive efforts.	Entails higher initial costs for automation tools, resources, and infrastructure, yet can result in long-term cost savings by reducing manual effort and enhancing testing efficiency.

4. What is Quality Control in Manual Testing?

Quality control in manual testing encompasses a variety of activities aimed at validating the accuracy, dependability, and efficiency of the testing process and its outcomes.

6. How Manual Testing fits into each stage of SDLC?

Here’s a breakdown of how manual testing is involved in each phase of the Software Development Life Cycle (SDLC):

• Requirements Gathering: Stakeholders define project requirements. Manual testers join requirement review sessions to understand expected functionalities and user behaviors.

• Analysis and Design: Software architecture and design are developed based on requirements. Manual testers collaborate with developers to grasp system designs and identify potential testing scenarios.

• Implementation (Coding): Developers write code according to design specifications. Manual testers may review code changes and offer insights on testability to ensure code meets requirements.

• Testing (Manual Testing): Testers execute test cases to validate software functionality, usability, and performance. Various manual testing types, such as functional testing and user acceptance testing, are conducted.

• Deployment: After testing, software is deployed to production. Manual testers may participate in final acceptance testing to ensure alignment with specified requirements.

• Maintenance: Software enters the maintenance phase for updates and bug fixes. Manual testers continue to contribute to regression testing to maintain software quality and reliability.

7. What is a test case and what are some of its key components?

In manual testing, a test case serves as a detailed guide for verifying the functionality, performance, or usability of a software application. It comprises specific steps, expected outcomes, and other relevant details necessary for test execution.

Here’s a breakdown of the typical components found in a test case:

• Test Case ID: An unique identifier assigned to the test case for easy tracking.

• Test Case Title: A descriptive title summarizing the purpose or objective of the test case.

• Test Steps: Detailed instructions specifying actions to be performed during the test, such as navigating the application, inputting data, or interacting with features.

• Expected Results: Anticipated outcomes or behaviors of the software after each step, including messages, interface changes, or displayed data.

• Preconditions: Conditions or prerequisites required before executing the test case to ensure the test environment is properly set up.

• Test Data: Input data or values necessary for test execution, which may include sample data, user credentials, or specific configurations.

• Actual Results: The observed outcomes or behaviors during test execution, where testers record any deviations from the expected results.

• Status: Indicates the current state of the test case (e.g., passed, failed, in progress).

• Priority and Severity: Priority signifies the importance or urgency of the test case, while severity indicates the impact of defects on software functionality or usability.

8. What is the Test Scenario?

In manual testing, a test scenario outlines a broad description of a particular functionality or feature within a software application that needs testing. Unlike test cases, which provide detailed step-by-step instructions, test scenarios offer a more general overview of the test objective without delving into specific actions.

9. What are the important components of a test case?

The key components of a test case include:

• Test Case ID
• Test Case Title
• Test Steps
• Expected Results
• Preconditions
• Test Data
• Actual Results
• Status
• Priority and Severity

10. What is the difference between validation and verification in software testing?

Verification ensures that the software meets its specified requirements, while validation ensures that the software meets the user’s needs and expectations. Verification focuses on checking whether the software is being built correctly, while validation focuses on whether the right product is being built.

11. Distinguish sanity testing and smoke testing.

Smoke testing is performed to assess the stability of the software build by checking critical functionalities, usually after receiving a new build. Sanity testing, on the other hand, is a narrow regression test that verifies specific areas of functionality to ensure that recent changes haven’t adversely affected them.

12. What is regression testing, and why is it important?

Regression testing involves retesting unchanged parts of the software to ensure that new changes haven’t introduced any unintended side effects or regressions. It is essential because software is often updated or modified, and regression testing helps maintain the integrity and stability of the application.

13. What is exploratory testing, and when is it used?

Exploratory testing involves testers concurrently learning, designing, and executing tests, dynamically exploring software functionalities. It’s employed in ambiguous requirement scenarios, to uncover defects missed by scripted tests, and to augment conventional testing methods.

14. How do you handle defects found during testing?

Detected defects are recorded in a defect tracking system, specifying reproduction steps, actual versus expected outcomes, and severity and priority levels. Testers then notify developers and work together to investigate, rectify, and validate fixes before retesting impacted functionalities.

15. What is Black box testing?

Black box testing in manual testing involves assessing software functionality without knowledge of its internal code. Testers focus solely on inputs and outputs, executing test cases based on specifications and requirements. They interact with the software through its interface, aiming to validate its behavior and detect defects. This method uncovers issues related to functionality, usability, performance, and security, prioritizing end-user perspective over internal workings.
