Today there are no tools built into Visual Studio to test WEB API. Using browsers, one can only test http GET requests. You need to use third-party tools like Postman, SoapUI, Fiddler or Swagger to perform a complete testing of the WEB API. In ASP.NET Core 2.2, a CLI based new dotnet core global tool named “http-repl” is introduced to interact with API endpoints. It’s a CLI based tool which can list down all the routes and execute all HTTP verbs. In this post, let’s find out how to use HTTP-REPL tool to test WEB API in ASP.NET Core 2.2.

Create Petstore like Swagger UI for ASP.NET Core WEB API
Swagger doesn’t need an introduction as it is the world’s largest framework of API developer tools for the OpenAPI Specification(OAS), enabling development across the entire API life-cycle, from design and documentation, to test and deployment. Swagger is an UI representation of your RESTful API. It allows anyone — be it your development team or your end consumers — to visualize and interact with the API’s resources having none of the implementation logic in place. The Petstore (created by the swagger team) is a demonstration of the beautiful Swagger UI. You can easily integrate the Swagger in your application, but the sad part is you will get a different UI, not same as available @ Petstore. In this post, let’s find out how to create Petstore like Swagger UI for ASP.NET Core WEB API.

Add Swagger to ASP.NET Core 2.0 Web API
Testing WEB APIs is a challenge, and it has a dependency on various third-party tools for proper and efficient testing. But swagger can make it easy. Swagger is an UI representation of your RESTful API. Swagger UI allows anyone — be it your development team or your end consumers — to visualize and interact with the API’s resources having none of the implementation logic in place. It’s automatically generated from your Swagger specification, with the visual documentation, making it easy for back-end implementation and client-side consumption. Earlier, I posted about adding swagger with ASP.NET Core but it no longer works with ASP.NET Core 2.0 due to new changes with ASP.NET Core 2.0. In this post, we’ll see how to add Swagger to ASP.NET Core 2.0 Web API. Read More
