This open source project serves to allow developers to write high-performance tests with little configuration and an easy-to-use API. Established in 2011, Jest has received over 90% user ratings in a number of different studies, including JS status.
It was open source in 2014 and maintained part-time by Meta engineers until 2016, when former Meta engineer and current Jest chief associate, Christoph Punishes, redesigned the project.
In 2018, Meta announced a new Jest open team to support non-Meta employees who develop and maintain Jest. Since then, almost all contributions to Jest have been made by the open source community.
This eventually led to the decision to transfer ownership of the project to the community itself.
The OpenJS Foundation currently hosts a number of open source projects, including JQuery, Node.js, Electron, AMP and webpack. In addition, it is supported by several corporate and end users, such as GoDaddy, Google, IBM, Intel, Joyant and Microsoft.
In the coming months, Jest will go through the OpenJS Foundation’s incubation program checklist. This includes transferring Jest’s domain, repo, website and other assets to OpenJS, as well as updating the Code of Conduct and the Employee License Agreement.
This move will not change the way Jest is developed or launched and has no direct effect on developers who are currently using Jest to test their applications.
A project charter will also be published and new governance policies will be established to document the process of gaining access to commitments as well as the process of selecting leaders.
