STLC stands for Software Testing Life Cycle. It is a process followed to ensure quality in software development.

• STLC involves planning, designing, executing, and reporting of tests.

• It includes various stages like requirement analysis, test planning, test case development, test execution, and test closure.

• The main objective of STLC is to identify defects early in the development cycle and ensure that the software meets the specified requirements.

• STLC is an integral part of sof...read more

Sanity testing is a type of software testing that checks whether the basic functionalities of the application are working properly or not.

• It is performed after the completion of functional testing

• It is a subset of regression testing

• It helps to identify the defects early in the testing cycle

• It is a quick and shallow testing process

• Example: Checking if the login page is working properly

Regression testing is the process of testing changes made to a software application to ensure that existing functionality still works.

• It is performed after making changes to the software

• It ensures that existing functionality is not affected by the changes

• It helps to catch any defects or bugs introduced by the changes

• It can be automated to save time and effort

• Examples include testing after bug fixes, new feature additions, and software updates

Smoke testing is a preliminary testing technique to check if the software build is stable enough for further testing.

• It is a quick and shallow testing technique

• It is performed to ensure that the critical functionalities of the software are working fine

• It is usually done after a new build is deployed

• It helps to identify major issues early in the testing cycle

• It is not a substitute for comprehensive testing

Priority and severity are used to classify issues based on their impact and urgency.

• Priority refers to the urgency of fixing an issue, while severity refers to the impact of the issue on the system or users.

• Priority is usually assigned based on the business needs and impact on the project timeline.

• Severity is usually assigned based on the impact on the system or users, such as critical, major, minor, or cosmetic.

• For example, a critical bug that causes the system to crash woul...read more

Defect life cycle is the process of identifying, reporting, prioritizing, fixing, and verifying defects in software.

• Defect is identified by testing or user feedback

• Defect is reported to the development team

• Defect is prioritized based on severity and impact

• Defect is fixed by the development team

• Defect fix is verified by testing

• Defect is closed if verified or reopened if not fixed

OOP features include abstraction, encapsulation, inheritance, polymorphism, and dynamic binding.

• Abstraction: hiding implementation details and showing only necessary information

• Encapsulation: bundling data and methods that operate on that data within a single unit

• Inheritance: creating new classes from existing ones, inheriting properties and methods

• Polymorphism: ability of objects to take on multiple forms or behaviors

• Dynamic binding: determining which method to execute at ru...read more

React JS is a JavaScript library for building user interfaces.

• React JS allows for building reusable UI components.

• It uses a virtual DOM for efficient rendering.

• React JS is popular for single-page applications and dynamic web interfaces.

• It follows a component-based architecture.
