Configuration Merging

This feature allows users to merge multiple configuration objects into one. It is useful for combining default settings with user-provided settings, ensuring flexibility and customization of test setups.

const { merge } = require('@wdio/config');
const defaultConfig = { baseUrl: 'http://localhost' };
const userConfig = { baseUrl: 'http://example.com' };
const finalConfig = merge(defaultConfig, userConfig);
console.log(finalConfig);

Configuration Validation

This feature ensures that the configuration object meets the necessary schema requirements set by WebdriverIO. It helps in catching configuration errors early in the setup process, thus avoiding runtime errors during test execution.

const { validateConfig } = require('@wdio/config');
const wdioConfig = { specs: ['./tests/specs/*'], capabilities: [{ browserName: 'chrome' }] };
validateConfig(wdioConfig);
console.log('Configuration is valid!');
