We had to test a facebook chat-bot built with nodejs. This app is a webhook for FB to push the chat messages down to our app. This is how we achieved it On Windows: Download JMeter from  here . Now run the jmeter.bat, this will open up a java GUI where you can easily configure the endpoints you want to test. Add a thread group and set the number of users/thread you want to spawn to test your API Add an Http request sampler  Fill in the intuitive fields like URL, request body, Method, etc., For setting up HTTP headers like content-type or authorization fields right click on HTTP request and add config element HTTP header manager, then the key values as you may To see the results on all the requests that will spawn create add listener View results tree.  You are ready ...

Simply Notes #3: Multiple File Upload in ASP.Net MVC

Here is requirement I tripped into "Give me an option to upload multiple images which blah blah blah". Blah blah part is where it says do not use the easy way like input type multiple .

The Action here is to ModelBind image array to the action parameter The Bind  attribute takes care of the naming convention that takes behind the scenes when rendering the element. If you are using the template to render any element the framework will append the model property names of the nested elements. In this example it will render input element with name="PIma...
