CRUD new1

In this course, you will learn the fundamentals of Ruby on Rails to build your own application.

You will start by learning how to create a new project, deploy to a Rails server, and the Rails design pattern. After that, you’ll learn how to perform CRUD operations, handle user authentication, and manage sessions.

Once you finish this course, you’ll have the foundations in place to build more complex applications to add to your portfolio.

# Integration testing
Integration testing is done to check how various parts of the application interact. For example, creating a new link involves interaction between your controller and your model, and after successful creation, the controller has to render a view. If you want to check whether this interaction is successful, you can write an integration test for it.

## Pre-test configuration
Before you can start writing your test, you must make some configurations keeping in mind the structure of your application.

Specifically, you must keep the following points in mind:

1. Your `Link` model is associated with your `User` model. Every `link` you create in your fixtures must have a `user` attribute.

2. All actions, other than `index` and `show`, require an *active user session* to be accessed. This means a user must be signed in to create or delete a link.

Since you cannot disable these features of your application, you must make some configurations to your test environment before you can run tests on the full range of actions in your  `Links` controller.

### `test/controllers/links_controller_test.rb `

In `links_controller_test.rb` you will make the following additions to `setup`:


Learn about integration testing in Rails and write tests for your links controller.
