browser.config is throwing type errors for custom fields in WDIO v7

[velgersdyk25]

Recently upgraded from v6 to v7 and encountered a type error _Error:(10, 31) TS2339: Property 'AUTH0_BASE_URL' does not exist on type 'Testrunner | WebdriverIO'._. This is when its called using browser.config call. Environment (please complete the following information):

• WebdriverIO version: 7.9
• Mode:WDIO Testrunner
• If WDIO Testrunner, running sync
• Node.js version:14.16.0
• NPM version:v7.11.2

Config of WebdriverIO / eslint-disable @typescript-eslint/no-var-requires / const debug = process.env.DEBUG; const defaultMochaTimeout = 600000000000000; const WebdriverIOHelpers = require("../../lib/util/webdriverIOHelpers"); const ElementHelpers = require("../../lib/util/elementHelpers"); const windowHeight = 1080; const windowWidth = 1920;

require("dotenv").config();

exports.baseConfig = { AUTH0_BASE_URL: "google.com" waitforTimeout: 10000, reporters: [ "spec", [ "mochawesome", { outputDir: "./Results", outputFileFormat: function(opts) { return results-${opts.cid}.${opts.capabilities}.json; }, }, ], ], mochawesomeOpts: { includeScreenshots: true, },

mochaOpts: { ui: "bdd", timeout: debug ? 9000000000 : defaultMochaTimeout, requires: ["tsconfig-paths/register"], }, // onPrepare: function(config, capabilities) { // }, /**

• Gets executed before test execution begins. At this point you can access to all global
• variables like browser. It is the perfect place to define custom commands.
• @param {Array.

Do you still have this issue when using browser.options instead of browser.config? We are planning to remove browser.config in favor of browser.options.

When you are extending your config with custom properties you should extend the WebdriverIO config interface and assign that instead in order to get the correct typing. I don't see anything wrong here really.

I agree with @erwinheitzman here that extending the WebdriverIO type should be the way to go. Closing.
