Black box testing focuses on testing the functionality of a software without knowing its internal code, while white box testing involves testing the internal code structure.

• Black box testing is based on external expectations and specifications

• White box testing is based on internal code structure and logic

• Black box testing is also known as functional testing

• White box testing is also known as structural testing

• Example: In black box testing, a tester tests a login page without k...read more

Manual testing is the process of manually testing software for defects, errors, and bugs.

• Manual testing involves testers executing test cases without the use of automation tools.

• Testers follow predefined test cases to ensure the software functions correctly.

• Manual testing is time-consuming but allows for human intuition and creativity in finding bugs.

• Examples of manual testing include exploratory testing, ad-hoc testing, and regression testing.

Defect cascading is when a defect in one part of the software causes defects in other parts.

• Occurs when a defect in one module goes undetected and affects other modules

• Can lead to a chain reaction of defects throughout the software

• Often results from poor testing practices or lack of communication among team members

Defect seeding is the intentional introduction of defects into a software system to evaluate the effectiveness of testing processes.

• Defect seeding helps in identifying weaknesses in the testing process

• Common techniques include adding bugs to the codebase or injecting faults into the system

• It is used to measure the thoroughness and efficiency of testing

Defect life cycle is the process of identifying, reporting, fixing, retesting, and closing software bugs.

• Defect identification: Bugs are found during testing or by users.

• Defect reporting: Bugs are documented in a bug tracking system.

• Defect fixing: Developers address and resolve the reported bugs.

• Defect retesting: Testers verify that the bug is fixed.

• Defect closing: Once verified, the bug is marked as closed.

QA stands for Quality Assurance and involves the process of ensuring quality in software development. QC stands for Quality Control and involves the process of verifying quality in the final product.

• QA focuses on preventing defects in the software development process

• QC focuses on identifying defects in the final product

• QA involves processes like code reviews, unit testing, and continuous integration

• QC involves processes like testing, debugging, and validation

• Example: QA ensur...read more

Inheritance is a mechanism in object-oriented programming where a class can inherit properties and methods from another class.

• Inheritance allows for code reuse and promotes code organization.

• The class that is being inherited from is called the parent or base class.

• The class that inherits from the parent class is called the child or derived class.

• The child class can access all the public and protected members of the parent class.

• Example: A class Animal can be the parent class ...read more

Severity and priority are used to classify the importance and urgency of issues in software development.

• Severity refers to the impact of an issue on the system or business.

• Priority refers to the urgency of fixing an issue.

• Severity is usually categorized as low, medium, or high.

• Priority is usually categorized as low, medium, or high.

• For example, a critical bug that causes the system to crash would have high severity and high priority.
