Shared Store Service

Exchange data between main process and workers (specs).

Installation​

The easiest way is to keep @wdio/shared-store-service as a devDependency in your package.json, via:

npm install @wdio/shared-store-service --save-dev

Instructions on how to install WebdriverIO can be found here.

Usage​

Get/set a value (plain object) to/from the store by key (string).

browser.sharedStore.set('key', 'value') set value to store

browser.sharedStore.get('key') get value from store (returns 'value')

You could also directly access to setValue and getValue async handlers. Make sure you properly call them with the await keyword.

import { setValue } from '@wdio/shared-store-service'

// ...
onPrepare: [async function (config, capabilities) {
await setValue('foo', 'bar')
}],

IMPORTANT! Every spec file should be atomic and isolated from others specs. The idea of the service is to deal with very specific environment setup issues. Please avoid sharing test execution data!

Configuration​

Just add shared-store to services list and the sharedStore object will be accessible to you in your test.

// wdio.conf.js
exports.config
// ...
services: ['shared-store'],
// ...
};
