As you all know, if you create a sample API project you will get a folder HelpPage in Areas. This is for adding the XML description to each controller and actions we use in our API. If you document it well, any one can understand your API, so that you don’t need to explain what your API will do and what would be the output. If you are new to HelpPage implementation in API, please see here: API help page controller action description in Web API. Here I am going to create a Web API with the help page descriptions in Visual Studio 2015. And once the project is ready I will install the WebApiTestClient package to my solution. I hope you will like this.
Please be noted that this package is not officially released by Microsoft. This is a prototype created by Yao – MSFT

Background
For the past few months, I had been working with API projects. Recently I was asked to create an application to test the API I created so that the testing team can test the API easily. Yes I agree that we have tools like Fiddler and Post Man for the same. Still we thought to create our own. As I started my development, I came to know about the package WebApiTestClient which does what we wanted. Finally we decided to stop developing the application and used this wonderful package. Here I am going to show you how can we use this.
Prerequisites
- Visual Studio With Web API Installed
Things we are going to do:
The following are the tasks we are going to do.
- Setting up database
- Creating an Entity Framework
- Creating API controller with the Model Created
- Installing WebApiTestClient
- Configuring WebApiTestClient
- Testing WebApiTestClient
Setting up database
Here I am going to create a database which I created for my demo purposes, you can always create this database by running the queries mentioned here.

Our database is ready, now create a Web API application in visual studio and then entity with the above mentioned database.
Creating Entity
If you don’t know how to create an entity in your solution, please read that here. I have mentioned the steps to be followed in that article. Once you have created the entity, you are good to go and create a API controller with the entity created. If you do so, The CRUD actions will be created automatically for you. You may need to edit those actions according to your needs.
Web API 2 Controller with actions, using Entity Framework
Select the Model Class, DBContext then name your controller and click OK. I hope a controller with the CRUD actions. Now we can modify that as follows.
Installing WebApiTestClient
To install the package, please go to your Package Manage Console from NuGet Package Manager and run the following command.
- Install-Package WebApiTestClient
You can always get the details about the package here.
Once you install the package, you can see some files are added to your Script and Area folder as preceding.
Script and Area Folder
Configuring WebApiTestClient
To configure the WebApiTestClient, please go to the folder Areas->Views->Help and then click on Api.cshtml
Api Cshtml
This is the view shown when you click on each API in your help page. Now add the preceding code block to that view.
- @Html.DisplayForModel("TestClientDialogs")
- @section Scripts
- {
- <link href="~/Areas/HelpPage/HelpPage.css" rel="stylesheet" type="text/css" />
- @Html.DisplayForModel("TestClientReferences")
- }
Code Block
Testing WebApiTestClient
Now run your API application and go to the help page for any controller action, you can see a button called Test API on the bottom. If you click on that you will get a pop where you can test your API action.
Test API Client Output
Now if you send your request by clicking the send button, you will get an output as follows.
Test API Client Output With Response
You can always give id parameter as follows.
Test Client With Parameters
You can also give content-length and content-type in your post request as follows.
Test Client With Post
Test Client With PUT Request

Your turn. What do you think?
A blog isn’t a blog without comments, but do try to stay on topic. If you have a question unrelated to this post, you’re better off posting it on C# Corner, Code Project, Stack Overflow, Asp.Net Forum instead of commenting here.
