In an ASP.NET Core project, application dependencies and SDK versions are typically defined in the .csproj files. These files specify the packages, libraries, and tools required for the project. The .csproj files play a crucial role in managing the project's dependencies and ensuring the correct versions are used.

SignalR primarily uses the WebSocket protocol for real-time communication due to its low latency and bidirectional capabilities. WebSocket provides a full-duplex communication channel, making it ideal for applications requiring instant updates. SignalR gracefully falls back to other techniques like HTTP long polling or Server-Sent Events for compatibility with older browsers or network restrictions.

To enforce a consistent structure and look across multiple views, developers use a Layout page in Razor. Layout pages define the common structure, such as headers and footers, shared across multiple views, ensuring a cohesive design.

In ASP.NET Core, the AddMvc method is used to add MVC route handlers and configure the use of default routes. This method sets up MVC services, including routing, and is essential for building web applications with ASP.NET Core MVC. It's typically called within the Startup class's ConfigureServices method.

Migrations in ASP.NET Core Identity are primarily used to define and manage the database schema for user-related data. They allow you to create, update, and evolve the database structure to accommodate changes in your Identity-related models and requirements.

To make a page accessible to both authenticated and non-authenticated users in ASP.NET Core, you can use the [AllowAnonymous] attribute on the controller or action that corresponds to the page. This attribute allows both types of users to access the page without requiring authentication.

Using meaningful variable names in automation scripts is important for improved code maintainability. Meaningful names make the code self-explanatory and help developers and testers understand the purpose of variables without the need for extensive comments. This practice contributes to easier debugging, collaboration, and long-term maintenance of the automation scripts.

Refactoring code in automation scripts involves restructuring and improving the existing code without changing its external behavior. This contributes to debugging by making the code more readable and understandable, thus simplifying the identification and resolution of issues. Additionally, refactoring enhances script maintainability and can lead to optimized scripts, potentially reducing execution time.

In Keyword Driven Testing Framework, a 'Keyword' represents an action or operation to be performed on the application under test. Keywords are the building blocks of test scripts, defining the specific steps or interactions that the automation framework should execute. Testers can create and customize keywords to abstract and modularize test logic, enhancing the flexibility and maintainability of the test automation framework.

Network virtualization is crucial in mobile testing to simulate different network conditions. It allows testers to assess how the mobile application performs under various network speeds, such as 3G, 4G, or unstable connections. This helps identify potential performance issues related to network latency, bandwidth, and connectivity, ensuring a more realistic evaluation of the app's behavior in real-world scenarios.

The Keyword Driven Testing Framework aids in complex testing scenarios by allowing non-technical stakeholders, such as business analysts or domain experts, to create and modify tests using a set of predefined keywords. This abstraction layer simplifies test development and execution, enabling collaboration between technical and non-technical team members. It also facilitates easier maintenance and updates to test cases without requiring in-depth programming knowledge.

Postman is known for its key feature in API testing, which is API design and documentation. It provides a user-friendly interface for creating, testing, and managing APIs. With Postman, testers can easily design and document APIs, create and send requests, and analyze responses. This makes Postman a valuable tool for API testing and collaboration among developers and testers in the API development process.
