Recommended Title for "Sql Interview Questions For Manual Testing"
Sql Interview Questions For Manual Testing
SQL interview questions for manual testing are designed to assess a candidate's knowledge and understanding of SQL, a programming language used to interact with databases. These questions may cover topics such as data manipulation, data retrieval, joins, constraints, and data types. The interviewer may also ask hypothetical scenarios to test the candidate's problem-solving skills and ability to write efficient and effective SQL queries. It is important for the candidate to have a strong understanding of SQL concepts and functions, as well as practical experience in using SQL in a testing environment.

1 - What is manual testing?
Manual testing is a type of software testing where the tester performs tests by hand without the use of any automated tools. This involves executing test cases and verifying the actual results against the expected results to ensure the quality of the software. It is a validated and customized approach to testing that covers both functional and non functional aspects of the software.
2) What is the difference between verification and validation?
Verification is the process of evaluating a system or component to determine if it meets the specified requirements. It involves checking documents, design, code, etc. to ensure that all the requirements have been addressed. On the other hand, validation is the process of evaluating a system or component to determine if it meets the user's requirements and expectations. This involves actual testing of the system to ensure that it performs as expected.
3) What is the difference between system testing and integration testing?
System testing is a level of software testing where the entire system is tested as a whole in an environment that closely resembles the production environment. It tests the functionality, reliability, performance, security, and usability of the system. Integration testing, on the other hand, is a level of software testing where individual modules are combined and tested as a group to identify any interface defects and ensure the proper integration of different modules.
4) What are the different types of testing?
The different types of testing include unit testing, integration testing, system testing, acceptance testing, regression testing, functional testing, performance testing, security testing, usability testing, and exploratory testing.
5) What is a test case?
A test case is a set of steps or conditions that are executed by a software tester to determine the expected behavior of a particular feature or function of the software. It has a precise description of the actions to be taken and the expected results.
6) What is the difference between priority and severity?
Priority refers to the importance or urgency of fixing a defect. It is usually determined by the impact of the defect on the business or end users. Severity, on the other hand, refers to the degree of impact a defect has on the system's functionality. It is usually evaluated based on the severity of the issue, its potential to cause harm, and the impact on the user's experience.
7) What is smoke testing?
Smoke testing is a type of software testing that is performed to verify if the critical or most important functionalities of a software system are working correctly after a new build or release. It is usually performed before any detailed testing to identify any significant issues that may prevent further testing.
8) What is a bug and how do you track it?
A bug is a coding error or flaw in the software that causes it to malfunction or not perform as expected. To track a bug, it needs to be logged in a bug tracking tool with details such as the issue description, steps to reproduce, the affected system, and screenshots. The bug then goes through a lifecycle of being reviewed, assigned, fixed, retested, and closed.
9) What is exploratory testing?
Exploratory testing is an informal approach to software testing where the tester explores the software without any specific test cases or plans. The goal of exploratory testing is to identify defects that may have been missed by traditional testing methods. It allows the tester to use their skills, experience, and creativity to uncover potential issues in the software.
10) How do you ensure the quality of your test cases?
To ensure the quality of test cases, they should be designed with clear objectives, detailed steps, and expected results. They should also cover all possible scenarios and be easily maintainable. Peer reviews and walkthroughs can also help improve the quality of test cases.
11) What is the difference between a test script and a test case?
A test case is a set of instructions or conditions to be tested, while a test script is a written set of code that the tester executes in order to test the functionality of the system. Test cases are specific to each feature or function, while test scripts can be reused for different test cases.
12) What is boundary value analysis?
Boundary value analysis is a black box testing technique used to identify any defects at the boundaries of input domains. It involves testing values at the boundary limits and just outside of the boundary limits to ensure that the software behaves as expected.
13) What is a test plan?

A test plan is a document that outlines the approach, resources, and schedule for carrying out a particular test. It includes the objectives, scope, strategy, and communication plan for the testing phase of a project.
14) What is the difference between static and dynamic testing?
Static testing is a testing technique where the code is reviewed without actually executing it. It involves techniques like walkthroughs, code reviews, and inspections to identify any defects or issues early in the SDLC. Dynamic testing, on the other hand, involves executing the code and analyzing the actual behavior of the system to find defects.
15) What are the key components of a bug report?
A bug report should include a title, a description of the issue, steps to reproduce, expected and actual results, screenshots or videos, the affected system environment, and any other relevant details. It should also include the severity and priority of the bug and the name of the tester who reported it.
