Often the quest of making things more efficient boils down to a matter of milliseconds. gRPC, short for “gRPC Remote Procedure Call,” is Google’s fast open source remote procedure call (RPC) framework that can run anywhere.
gRPC is built on top of HTTP/2, while REST – the standard protocol for the web APIs today – depends heavily on HTTP 1.1. As a Binary protocol HTTP/2 is more efficient to parse than the Textual HTTP 1.1. Even though gRPC has been proved to be faster than REST in many tests, it’s popularity has suffered from the lack of support to web clients. So far testing tools for gRPC API services have been very basic, lacking pretty much all the important features available for REST API testing. Because high-quality testing tools are a vital part of software development, we have developed a new gRPC Tester.
