Regression, Retesting, Dynamic, Static, and Unit Testing are all important software testing techniques.

• Regression testing ensures that changes to the software do not introduce new bugs.

• Retesting is the process of testing a previously failed test case again after the bug has been fixed.

• Dynamic testing involves executing the code and observing its behavior.

• Static testing involves reviewing the code without executing it.

• Unit testing is the process of testing individual units or ...read more

Positive testing is testing with valid inputs to check if the system behaves as expected. Negative testing is testing with invalid inputs to check if the system handles errors gracefully.

• Positive testing verifies if the system functions as expected with valid inputs.

• Negative testing verifies if the system handles errors gracefully with invalid inputs.

• Positive testing ensures that the system meets the requirements and specifications.

• Negative testing ensures that the system can...read more

Software testing is the process of evaluating a software application or system to find defects and ensure it meets the specified requirements.

• Testing is done to identify defects and ensure the software meets the requirements

• It involves executing the software with the intent of finding errors

• Testing can be done manually or with the help of automated tools

• Types of testing include functional, performance, security, and usability testing

• Testing is an iterative process that contin...read more

Stress testing tests the system's ability to handle extreme conditions, while load testing tests its performance under normal conditions. Manual testing is done by humans to find defects, while functional testing checks if the system meets requirements.

• Stress testing checks the system's response to extreme conditions like high traffic or low memory.

• Load testing checks the system's performance under normal conditions like average traffic.

• Manual testing is done by humans to fin...read more

Functional test cases verify if the software meets the requirements while non-functional test cases verify the software's performance.

• Functional test cases ensure the software meets the functional requirements

• Non-functional test cases ensure the software's performance, usability, and security

• Functional test cases are based on user requirements and use cases

• Non-functional test cases are based on performance, reliability, and security requirements

• Examples of functional test cas...read more

Priority and severity are terms used in software testing to indicate the importance and impact of a defect.

• Priority refers to the level of urgency in fixing a defect, based on its impact on the system and business goals.

• Severity refers to the degree of impact a defect has on the system's functionality and user experience.

• Example: A defect that causes the system to crash would have high severity, while a defect that affects a minor feature would have low severity but high prio...read more

Waterfall model is a linear sequential approach to software development while V-model is a variation of the waterfall model.

• Waterfall model follows a sequential approach where each phase must be completed before moving to the next phase.

• V-model is a variation of the waterfall model where testing is done in parallel with each phase of development.

• Waterfall model is less flexible and changes cannot be made easily once a phase is completed.

• V-model is more flexible and allows for...read more

Black box testing is testing without knowledge of internal workings, while white box testing is testing with knowledge of internal workings.

• Black box testing focuses on external behavior and functionality

• White box testing focuses on internal code structure and implementation

• Black box testing is often used for user acceptance testing

• White box testing is often used for unit testing and code coverage analysis

White box testing is testing the internal structure of the software while black box testing is testing the functionality without knowledge of the internal structure.

• White box testing is also known as structural testing

• Black box testing is also known as functional testing

• White box testing requires knowledge of the internal code and logic

• Black box testing does not require knowledge of the internal code and logic

• Examples of white box testing include unit testing and integration ...read more

Verification ensures that the software meets the requirements and specifications, while validation ensures that the software meets the customer's needs and expectations.

• Verification is the process of evaluating the software at various stages to ensure that it meets the specified requirements and standards.

• Validation is the process of evaluating the software at the end of the development process to ensure that it meets the customer's needs and expectations.

• Verification is a st...read more

SDLC stands for Software Development Life Cycle and STLC stands for Software Testing Life Cycle.

• SDLC is a process followed by development teams to design, develop, test and deploy software.

• STLC is a process followed by testing teams to plan, design, execute and report on software testing.

• SDLC includes phases like planning, analysis, design, implementation, and maintenance.

• STLC includes phases like test planning, test design, test execution, and test closure.

• Both SDLC and STLC...read more

Acceptance testing is the process of evaluating a system or software based on user requirements.

• It is performed to ensure that the system meets the user's expectations and requirements.

• It is usually the final phase of testing before the system is released to the end-users.

• It can be performed manually or using automated tools.

• Examples include User Acceptance Testing (UAT) and Operational Acceptance Testing (OAT).
