In which type of testing do you test individual components or units of software in isolation?
- Integration Testing
- System Testing
- End-to-End Testing
- Unit Testing
Unit testing is the practice of testing individual components or units of software in isolation from the rest of the application. It helps identify issues within these units before integrating them into the larger system.
When creating a custom Tag Helper, which class should it derive from?
- TagHelper
- Controller
- RazorPage
- Model
When creating a custom Tag Helper in ASP.NET Core, the class should derive from the built-in TagHelper class. This base class provides essential methods and properties for working with HTML elements and attributes within Razor Views, making it the foundation for creating custom Tag Helpers.
How can you override the default layout specified in the _ViewStart.cshtml for a specific Razor view?
- Using the @layout directive in the view
- By modifying the _ViewStart.cshtml file
- By setting the layout property in the controller
- By using the @section directive
You can override the default layout specified in the _ViewStart.cshtml for a specific Razor view by using the @layout directive in the view file itself. This allows you to customize the layout for a particular view without affecting the application-wide layout defined in _ViewStart.cshtml.
How can you specify a different layout for a specific Razor view other than the default layout?
- Using the Layout property in the Razor view
- By configuring the layout in the Startup.cs file
- By using the @page directive
- By adding a custom HTML
element in the view
You can specify a different layout for a specific Razor view by using the Layout property within the Razor view itself. This allows you to override the default layout defined in the _ViewStart.cshtml or any other global configuration.
After writing your ASP.NET Core application code, you want to build and run your application using a command-line tool. Which tool would you use for this purpose?
- dotnet build
- npm start
- ng serve
- python run
To build and run an ASP.NET Core application from the command line, you would use the dotnet build command. This command compiles your application and prepares it for execution.
In Razor forms, the _______ tag helper can be used to generate hidden input fields.
- @Html.Hidden
In Razor forms, you can use the @Html.Hidden tag helper to generate hidden input fields. This is commonly used when you need to include data in the form that should be submitted but not displayed to the user. Hidden fields are often used to store things like unique identifiers or state information.
You are tasked with storing custom logging settings for different environments (e.g., Development, Staging, Production) in an ASP.NET Core project. Which mechanism should you primarily use?
- Environment Variables
- AppSettings.json
- Hardcoding in Code
- Database Storage
In ASP.NET Core, the recommended way to store configuration settings for different environments is by using appsettings.json files. These files can contain environment-specific configuration sections, allowing you to maintain settings separately for Development, Staging, and Production environments without modifying the code.
Imagine you have two action methods in your controller: one for handling the creation of products and another for displaying a specific product's details based on its ID. How can you utilize attribute routing to distinguish these two methods?
- [HttpGet("products/create")] and [HttpGet("products/details/{id}")]
- [Route("create")] and [Route("details/{id}")]
- [HttpGet("{controller=Products}/create")] and [HttpGet("{controller=Products}/details/{id}")]
- [HttpGet("{action=create}")] and [HttpGet("{action=details}/{id}")]
Attribute routing allows you to specify route templates for actions directly within your controller using attributes like [HttpGet] and [Route]. To distinguish the two methods, you can use attribute routing like [HttpGet("{controller=Products}/create")] for product creation and [HttpGet("{controller=Products}/details/{id}")] for displaying product details, providing clear and distinct routes for each action.
In the context of user registration in ASP.NET Core, what does validation primarily ensure?
- Ensures that users provide a valid email address
- Ensures that users enter a strong password
- Ensures that users are above a certain age
- Ensures that users have a specific username
In the context of user registration in ASP.NET Core, validation primarily ensures that users provide a valid email address. This is important for sending account confirmation emails and maintaining accurate user information in the system. It's a critical step in verifying the authenticity of user accounts.
_________ is a practice where code and test are written together, iteratively improving each other.
- Test-Driven Development (TDD)
- Code-First Development
- Model-View-Controller (MVC)
- Behavior-Driven Development (BDD)
Test-Driven Development (TDD) is a software development methodology where tests are written before the actual code. Developers write small, focused tests that guide the development process, helping ensure that the code meets the requirements and is thoroughly tested.
