Spring IOC is a container that manages the lifecycle of Java objects. Dependency Injection is a design pattern that allows objects to be loosely coupled.

• Spring IOC is a container that manages the creation and destruction of objects

• Dependency Injection is a design pattern that allows objects to be loosely coupled

• Dependency Injection can be implemented without using Spring IOC

There is no one-size-fits-all answer to this question as it depends on the project requirements and team's expertise.

• Choose a framework that aligns with the project requirements and team's expertise

• Popular frameworks include Selenium, Appium, TestComplete, and Cypress

• Consider factors such as cross-browser compatibility, scalability, and maintainability

• Ensure the framework supports the programming language used in the project

• Evaluate the framework's reporting capabilities

Docker image has 3 layers: Base, Dependencies and Application.

• Base layer contains the OS and other system-level libraries.

• Dependencies layer contains the libraries and packages required by the application.

• Application layer contains the code and files specific to the application.

• Each layer is read-only and builds on top of the previous layer.

• Changes made to one layer do not affect the other layers.

• This layering approach makes Docker images lightweight and easy to share.

Agile is iterative and flexible, while waterfall is linear and rigid.

• Agile focuses on delivering working software in short iterations, while waterfall follows a sequential process.

• Agile welcomes changes in requirements, while waterfall requires a detailed plan upfront.

• Agile emphasizes collaboration and communication, while waterfall relies on documentation.

• Agile is suited for complex and uncertain projects, while waterfall is suited for well-defined projects.

• Examples of agile...read more

Stateful widgets can change their state during runtime, while stateless widgets cannot.

• Stateful widgets have a mutable state that can be modified.

• Stateless widgets are immutable and cannot be modified once created.

• Stateful widgets are used when the UI needs to change dynamically based on user interactions or other factors.

• Stateless widgets are used when the UI does not need to change and can be purely based on the input parameters.

• Stateful widgets use the 'State' class to man...read more
