Unit Testing Web API Using Swagger
In this
post we will use ASP.NET Web API to create a RESTful service and use a
NuGet package to create Swagger(Open API) specification.
Background
What is ASP.NET Web API?
ASP.NET Web
API is a framework that makes it easy to build HTTP services that reach a broad
range of clients, including browsers and mobile devices. ASP.NET Web API is an
ideal platform for building RESTful applications on the .NET Framework.
What is Swagger?
Swagger is a simple
yet powerful representation of your RESTful API. With the largest ecosystem of
API tooling on the planet, thousands of developers are supporting Swagger in
almost every modern programming language and deployment environment.
Advantages of Swagger
·
It's comprehensible for developers and
non-developers. Product
managers, partners, and even potential clients can have input into the design
of your API, because they can see it clearly mapped out in this friendly UI.
·
It's human readable and machine
readable. This means that not
only can this be shared with your team internally, but the same documentation
can be used to automate API-dependent processes.
·
It's easily adjustable. This makes it great for testing and debugging
API problems.
Using the code
Step 1 Adding Swagger to Web API Project
To add Swagger to Web
API, we just need to install an open source project called Swashbuckle via
NuGet.
Step 2 . Install NuGet Packages
Install "Swashbuckle.AspNetCore" NuGet package
in the solution.
After
Installation, you can see the swaggerconfig.cs under app_start folder in your project.
Step 3 View the Swaggerconfig.cs
Step 3 View the Swaggerconfig.cs
Step 4 Configure Swagger
At minimum, we need this line to enable Swagger and Swagger UI.
At minimum, we need this line to enable Swagger and Swagger UI.
Step 5 Now, run your API application and Just type
swagger after service. You will get the UI of swagger with list API including
whatever we wrote in services.

Click on Try it out button It will send a
response for Get and Post Method.
Happy Programming!!
