testEnvironment

Jest chooses where tests run. Node is the default; jsdom supplies browser APIs. Configure one environment for the project or select one file with a docblock.

Syntax

testEnvironment: 'node' | 'jsdom' | '<environment-path>'
testEnvironmentOptions: {}
/** @jest-environment <environment-name> */
