native-federation-tests
Bundler agnostic plugins to share federated components for testing purposes.
It aims to work for both vitest
and jest
.
Install
npm i -D @module-federation/native-federation-tests
This module provides two plugins:
NativeFederationTestsRemote
This plugin is used to concat the components that will be used in tests.
Configuration
{
moduleFederationConfig: any; // the same configuration provided to the module federation plugin, it is MANDATORY
additionalBundlerConfig?: TsupOptions; // additional `tsup` build options that will be merged with the one generated by the plugin, default is {}
distFolder?: string; // folder used to store the dist, default is './dist'
testsFolder?: string; // folder where all the files will be stored, default is '@mf-tests'
deleteTestsFolder?: boolean; // indicate if the concatenated components folder will be deleted when the job completes, default is 'true'
}
Additional configuration
Note that, for Webpack, the plugin automatically inject the devServer.static.directory
configuration.
For the other bundlers, you should configure it by yourself.
NativeFederationTestsHost
This plugin is used to download the concatenated components mock that will be used for tests.
Configuration
{
moduleFederationConfig: any; // the configuration same configuration provided to the module federation plugin, it is MANDATORY
testsFolder?: string; // folder where all the files have been stored, default is '@mf-tests',
mocksFolder?: string; // folder where the concatenated files will be stored, default is './__mocks__',
deleteTestsFolder?: boolean; // indicate if the tests mock folder will be deleted before the job starts, default is 'true'
maxRetries?: number; // The number of times the plugin will try to download the mocks before failing, default is 3
}
