API Simulator 0.2.1 Release

July 5, 2016


The previous release, v0.2.0 , introduced the API Recorder for HTTP. By acting as a man-in-the-middle between an API client and API provider, API Recorder captures the raw HTTP traffic between them and records it to files; the files then make it easier to model API simlets for existing APIs.

This release adds to API Recorder support for router mode in addition to the already supported HTTP proxy mode and HTTP tunneling (HTTP CONNECT method) of TLS/SSL traffic. When running in router mode, API Recorder dispatches the incoming requests to a pre-configured remote host and port while capturing all requests and responses.

Another addition in this release is the capability to inject slowness when sending responses back. Currently there are two implementations: fixed delay and random delay within a range (i.e. random value between 50 and 320 milliseconds).

Among the small changes and improvements is that API Client is now consistent with API Recorder in the use of command line argument to denote TLS/SSL – it now uses ‘-tls’ instead of ‘-ssl. The documentation was been updated accordingly.

We invite you to learn more about API Simulator, download and install it, and run the examples. Why not even create API simulations to help your own testing and development?
