This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@wordpress/jest-preset-default) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Usage

Brief explanations of options included

moduleNameMapper - all css and scss files containing CSS styles will be stubbed out.
modulePaths - the root dir of the project is used as a location to search when resolving modules.
setupFiles - runs code before each test which sets up global variables required in the testing environment.
setupFilesAfterEnv - runs code which adds improved support for Console object and React components to the testing framework before each test.
snapshotSerializers - makes it possible to use snapshot tests on Enzyme wrappers.
testMatch- includes /test/ subfolder in addition to the glob patterns Jest uses to detect test files. It detects only test files containing .js (or .ts) suffix. It doesn't match files with .spec.js suffix.
timers - use of fake timers for functions such as setTimeout is enabled.
transform - keeps the default babel-jest transformer.
verbose - each individual test won't be reported during the run.

Code is Poetry.
