Requests over a network to an API can be delayed for many reasons e.g. network congestion or excessive server load. For applications to be resilient they must be designed to handle these inevitable variabilities and tested to ensure optimum end user's experience, even when the back-end APIs are not working properly.
Mocklets provides a very easy way to test applications against these unexpected delays in back-end APIs. Mocklets lets you set response delays to each response, so you can test your application against different HTTP status codes and their respective delays.
The above api will respond with a delay of
Whenever Mocklets is instructed to add a delay in response, it adds a header
x-mocklets-delay to the response.
You can also control the delay duration using query params. Please refer this link for more.
