This article is a setp-by-step review/guide to meet some of the features of the Insomnia web-service testing client.
A notable feature of Insomnia is that it provides a very easy and quick way of organizing web-service request test cases within Environments that can contain Folders, which enables the creation of well structured testing projects.
In addition to the 'Environment/Folder' based organizing feature, Insomnia also allows the exporting/importing of web-service request test case projects in JSON format, which is greatly useful for distributing test case projects to third-party developers, testers and other people that are working on service-capable projects of any size and complexity.
