پیکربندی

Based on the setup type (e.g. using the raw protocol bindings, WebdriverIO as standalone package or the WDIO testrunner) there is a different set of options available to control the environment.

گزینه های WebDriver​

هنگام استفاده از بسته پروتکل webdriver گزینه های زیر تعریف می شوند:

protocol​

پروتکل مورد استفاده در هنگام برقراری ارتباط با سرور درایور.

Type: String
Default: http

hostname​

میزبان سرور درایور شما.

Type: String
Default: 0.0.0.0

port​

پورتی که سرور درایور شما روی آن است.

Type: Number
Default: undefined

path​

مسیری به سرور درایور شما.

Type: String
Default: /

queryParams​

پارامترهای درخواست که به سرور درایور انتشار می یابند.

Type: Object
Default: undefined

user​

نام کاربری سرویس ابری شما (فقط برای اکانت های Sauce Labs, Browserstack, TestingBot or LambdaTest کار می کند). در صورت تنظیم، WebdriverIO به طور خودکار ویژگی های اتصال را برای شما تنظیم می کند. اگر از ارائه‌دهنده ابری استفاده نمی‌کنید، می‌توان از آن برای احراز هویت هر بک اند WebDriver دیگری استفاده کرد.

Type: String
Default: undefined

key​

کلید دسترسی به سرویس ابری یا کلید مخفی شما (فقط برای اکانت های Sauce Labs, Browserstack, TestingBot or LambdaTest کار می کند). در صورت تنظیم، WebdriverIO به طور خودکار ویژگی های اتصال را برای شما تنظیم می کند. اگر از ارائه‌دهنده ابری استفاده نمی‌کنید، می‌توان از آن برای احراز هویت هر بک اند WebDriver دیگری استفاده کرد.

Type: String
Default: undefined

capabilities​

قابلیت(Capability) هایی را که می خواهید در جلسه WebDriver خود اجرا کنید را تعریف می کند. برای جزئیات بیشتر، پروتکل WebDriver را بررسی کنید. اگر درایور قدیمی‌تری را اجرا می‌کنید که از پروتکل WebDriver پشتیبانی نمی‌کند، برای اجرای موفقیت‌آمیز یک جلسه، باید از قابلیت‌های JSONWireProtocol استفاده کنید.

در کنار قابلیت‌های مبتنی بر WebDriver، می‌توانید گزینه‌هایی که خاص یک مرورگر و یا سازنده خاصی است را اعمال کنید که امکان پیکربندی عمیق‌تر را برای مرورگر یا دستگاه در راه دور فراهم می‌کند. اینها در اسناد سازنده مربوطه مستند شده اند، به عنوان مثال:

علاوه بر این، یک ابزار مفید Sauce Labs Automated Test Configurator است که به شما کمک می کند این شی را با کلیک کردن روی قابلیت های مورد نظر خود ایجاد کنید.

Type: Object
Default: null

مثال:

{
    browserName: 'chrome', // options: `chrome`, `edge`, `firefox`, `safari`
    browserVersion: '27.0', // browser version
    platformName: 'Windows 10' // OS platform
}

اگر تست های وب یا بومی را روی دستگاه های تلفن همراه اجرا می کنید، قابلیت(Capability) با پروتکل WebDriver متفاوت است. برای جزئیات بیشتر به Appium Docs مراجعه کنید.

logLevel​

سطح و میزان لاگ.

Type: String
Default: info
Options: trace | debug | info | warn | error | silent

outputDir​

دایرکتوری برای ذخیره همه فایل‌های لاگ اجرا کننده تست (از جمله لاگ‌های گزارش‌دهنده ها و لاگ wdio). اگر تنظیم نشود، همه گزارش‌ها به stdout ارسال می‌شوند. از آنجایی که اکثر گزارش‌دهنده ها برای لاگ در stdoutساخته شده اند، توصیه می شود از این گزینه فقط برای گزارش‌دهنده های خاصی استفاده شود که در آن انتقال گزارش به یک فایل منطقی تر است (مثلاً گزارش‌دهنده junit).

هنگامی که در حالت مستقل اجرا می شود، تنها گزارشی که توسط WebdriverIO ایجاد می شود، گزارش wdio خواهد بود.

Type: String
Default: null

connectionRetryTimeout​

مهلت زمانی برای هر درخواست WebDriver به درایور یا شبکه.

Type: Number
Default: 120000

connectionRetryCount​

حداکثر تعداد درخواست‌های مجدد به سرور سلنیوم.

Type: Number
Default: 3

agent​

به شما امکان می دهد از یک عامل سفارشی http/https/http2 برای درخواست استفاده کنید.

Type: Object
Default:

{
    http: new http.Agent({ keepAlive: true }),
    https: new https.Agent({ keepAlive: true })
}

headers​

Specify custom headers to pass into every WebDriver request. If your Selenium Grid requires Basic Authentification we recommend to pass in an Authorization header through this option to authenticate your WebDriver requests, e.g.:

import { Buffer } from 'buffer';
// Read the username and password from environment variables
const username = process.env.SELENIUM_GRID_USERNAME;
const password = process.env.SELENIUM_GRID_PASSWORD;

// Combine the username and password with a colon separator
const credentials = `${username}:${password}`;
// Encode the credentials using Base64
const encodedCredentials = Buffer.from(credentials).toString('base64');

export const config: WebdriverIO.Config = {
    // ...
    headers: {
        Authorization: `Basic ${encodedCredentials}`
    }
    // ...
}

Type: Object
Default: {}

transformRequest​

Function intercepting HTTP request options before a WebDriver request is made

Type: (RequestOptions) => RequestOptions
Default: none

transformResponse​

Function intercepting HTTP response objects after a WebDriver response has arrived. The function is passed the original response object as the first and the corresponding RequestOptions as the second argument.

Type: (Response, RequestOptions) => Response
Default: none

strictSSL​

Whether it does not require SSL certificate to be valid. It can be set via an environment variables as STRICT_SSL or strict_ssl.

Type: Boolean
Default: true

enableDirectConnect​

Whether enable Appium direct connection feature. It does nothing if the response did not have proper keys while the flag is enabled.

Type: Boolean
Default: true

cacheDir​

The path to the root of the cache directory. This directory is used to store all drivers that are downloaded when attempting to start a session.

Type: String
Default: process.env.WEBDRIVER_CACHE_DIR || os.tmpdir()

WebdriverIO​

The following options (including the ones listed above) can be used with WebdriverIO in standalone:

automationProtocol​

Define the protocol you want to use for your browser automation. Currently only webdriver is supported, as it is the main browser automation technology WebdriverIO uses.

If you want to automate the browser using a different automation technology, make you set this property to a path that resolves to a module that adheres to the following interface:

import type { Capabilities } from '@wdio/types';
import type { Client, AttachOptions } from 'webdriver';

export default class YourAutomationLibrary {
    /**
     * Start a automation session and return a WebdriverIO [monad](https://github.com/webdriverio/webdriverio/blob/940cd30939864bdbdacb2e94ee6e8ada9b1cc74c/packages/wdio-utils/src/monad.ts)
     * with respective automation commands. See the [webdriver](https://www.npmjs.com/package/webdriver) package
     * as a reference implementation
     *
     * @param {Capabilities.RemoteConfig} options WebdriverIO options
     * @param {Function} hook that allows to modify the client before it gets released from the function
     * @param {PropertyDescriptorMap} userPrototype allows user to add custom protocol commands
     * @param {Function} customCommandWrapper allows to modify the command execution
     * @returns a WebdriverIO compatible client instance
     */
    static newSession(
        options: Capabilities.RemoteConfig,
        modifier?: (...args: any[]) => any,
        userPrototype?: PropertyDescriptorMap,
        customCommandWrapper?: (...args: any[]) => any
    ): Promise<Client>;

    /**
     * allows user to attach to existing sessions
     * @optional
     */
    static attachToSession(
        options?: AttachOptions,
        modifier?: (...args: any[]) => any, userPrototype?: {},
        commandWrapper?: (...args: any[]) => any
    ): Client;

    /**
     * Changes The instance session id and browser capabilities for the new session
     * directly into the passed in browser object
     *
     * @optional
     * @param   {object} instance  the object we get from a new browser session.
     * @returns {string}           the new session id of the browser
     */
    static reloadSession(
        instance: Client,
        newCapabilities?: WebdriverIO.Capabilitie
    ): Promise<string>;
}

Type: String
Default: webdriver

baseUrl​

Shorten url command calls by setting a base URL.

  • اگر پارامتر url شما با /شروع می شود، baseUrl به قبل اضافه می شود (به جز مسیر baseUrl، اگر مسیری وجود داشته باشد دارد).
  • اگر پارامتر url بدون شماتیک یا / (مثلsome/path) شروع می شود، سپس baseUrl کامل مستقیما اضافه می شود.

Type: String
Default: null

waitforTimeout​

Default timeout for all waitFor* commands. (Note the lowercase f in the option name.) This timeout only affects commands starting with waitFor* and their default wait time.

To increase the timeout for a test, please see the framework docs.

Type: Number
Default: 5000

waitforInterval​

Default interval for all waitFor* commands to check if an expected state (e.g., visibility) has been changed.

Type: Number
Default: 100

region​

If running on Sauce Labs, you can choose to run tests between different data centers: US or EU. To change your region to EU, add region: 'eu' to your config.

Note: This only has an effect if you provide user and key options that are connected to your Sauce Labs account.

Type: String
Default: us

(only for vm and or em/simulators)

Testrunner Options​

The following options (including the ones listed above) are defined only for running WebdriverIO with the WDIO testrunner:

specs​

Define specs for test execution. You can either specify a glob pattern to match multiple files at once or wrap a glob or set of paths into an array to run them within a single worker process. All paths are seen as relative from the config file path.

Type: (String | String[])[]
Default: []

exclude​

Exclude specs from test execution. All paths are seen as relative from the config file path.

Type: String[]
Default: []

suites​

An object describing various of suites, which you can then specify with the --suite option on the wdio CLI.

Type: Object
Default: {}

capabilities​

The same as the capabilities section described above, except with the option to specify either a multiremote object, or multiple WebDriver sessions in an array for parallel execution.

You can apply the same vendor and browser specific capabilities as defined above.

Type: Object|Object[]
Default: [{ 'wdio:maxInstances': 5, browserName: 'firefox' }]

maxInstances​

Maximum number of total parallel running workers.

Note: that it may be a number as high as 100, when the tests are being performed on some external vendors such as Sauce Labs's machines. There, the tests are not tested on a single machine, but rather, on multiple VMs. If the tests are to be run on a local development machine, use a number that is more reasonable, such as 3, 4, or 5. Essentially, this is the number of browsers that will be concurrently started and running your tests at the same time, so it depends on how much RAM there is on your machine, and how many other apps are running on your machine.

You can also apply maxInstances within your capability objects using the wdio:maxInstances capability. This will limit the amount of parallel sessions for that particular capability.

Type: Number
Default: 100

maxInstancesPerCapability​

Maximum number of total parallel running workers per capability.

Type: Number
Default: 100

injectGlobals​

Inserts WebdriverIO's globals (e.g. browser, $ and $$) into the global environment. If you set to false, you should import from @wdio/globals, e.g.:

import { browser, $, $$, expect } from '@wdio/globals'

Note: WebdriverIO doesn't handle injection of test framework specific globals.

Type: Boolean
Default: true

bail​

If you want your test run to stop after a specific number of test failures, use bail. (It defaults to 0, which runs all tests no matter what.) Note: A test in this context are all tests within a single spec file (when using Mocha or Jasmine) or all steps within a feature file (when using Cucumber). If you want to control the bail behavior within tests of a single test file, take a look at the available framework options.

Type: Number
Default: 0 (don't bail; run all tests)

specFileRetries​

The number of times to retry an entire specfile when it fails as a whole.

Type: Number
Default: 0

specFileRetriesDelay​

Delay in seconds between the spec file retry attempts

Type: Number
Default: 0

specFileRetriesDeferred​

Whether or not retried spec files should be retried immediately or deferred to the end of the queue.

Type: Boolean
Default: true

groupLogsByTestSpec​

Choose the log output view.

If set to false logs from different test files will be printed in real-time. Please note that this may result in the mixing of log outputs from different files when running in parallel.

If set to true log outputs will be grouped by Test Spec and printed only when the Test Spec is completed.

By default, it is set to false so logs are printed in real-time.

Type: Boolean
Default: false

groupLogsByTestSpec​

Choose the log output view.

If set to false logs from different test files will be printed in real-time. Please note that this may result in the mixing of log outputs from different files when running in parallel.

If set to true log outputs will be grouped by Test Spec and printed only when the Test Spec is completed.

By default, it is set to false so logs are printed in real-time.

Type: Boolean
Default: false

services​

Services take over a specific job you don't want to take care of. They enhance your test setup with almost no effort.

Type: String[]|Object[]
Default: []

framework​

Defines the test framework to be used by the WDIO testrunner.

Type: String
Default: mocha
Options: mocha | jasmine

mochaOpts, jasmineOpts and cucumberOpts​

Specific framework-related options. See the framework adapter documentation on which options are available. Read more on this in Frameworks.

Type: Object
Default: { timeout: 10000 }

cucumberFeaturesWithLineNumbers​

List of cucumber features with line numbers (when using cucumber framework).

Type: String[] Default: []

reporters​

List of reporters to use. A reporter can be either a string, or an array of ['reporterName', { /* reporter options */}] where the first element is a string with the reporter name and the second element an object with reporter options.

Type: String[]|Object[]
Default: []

Example:

reporters: [
    'dot',
    'spec'
    ['junit', {
        outputDir: `${__dirname}/reports`,
        otherOption: 'foobar'
    }]
]

reporterSyncInterval​

Determines in which interval the reporter should check if they are synchronized if they report their logs asynchronously (e.g. if logs are streamed to a 3rd party vendor).

Type: Number
Default: 100 (ms)

reporterSyncTimeout​

Determines the maximum time reporters have to finish uploading all their logs until an error is being thrown by the testrunner.

Type: Number
Default: 5000 (ms)

execArgv​

Node arguments to specify when launching child processes.

Type: String[]
Default: null

filesToWatch​

A list of glob supporting string patterns that tell the testrunner to have it additionally watch other files, e.g. application files, when running it with the --watch flag. By default the testrunner already watches all spec files.

Type: String[]
Default: []

updateSnapshots​

Set to true if you want to update your snapshots. Ideally used as part of a CLI parameter, e.g. wdio run wdio.conf.js --s.

Type: 'new' | 'all' | 'none'
Default: none if not provided and tests run in CI, new if not provided, otherwise what's been provided

resolveSnapshotPath​

Overrides default snapshot path. For example, to store snapshots next to test files.

wdio.conf.ts
export const config: WebdriverIO.Config = {
    resolveSnapshotPath: (testPath, snapExtension) => testPath + snapExtension,
}

Type: (testPath: string, snapExtension: string) => string
Default: stores snapshot files in __snapshots__ directory next to test file

tsConfigPath​

WDIO uses tsx to compile TypeScript files. Your TSConfig is automatically detected from the current working directory but you can specify a custom path here or by setting the TSX_TSCONFIG_PATH environment variable.

See the tsx docs: https://tsx.is/dev-api/node-cli#custom-tsconfig-json-path

Type: String
Default: null

Hooks​

The WDIO testrunner allows you to set hooks to be triggered at specific times of the test lifecycle. This allows custom actions (e.g. take screenshot if a test fails).

Every hook has as parameter specific information about the lifecycle (e.g. information about the test suite or test). Read more about all hook properties in our example config.

Note: Some hooks (onPrepare, onWorkerStart, onWorkerEnd and onComplete) are executed in a different process and therefore can not share any global data with the other hooks that live in the worker process.

onPrepare​

Gets executed once before all workers get launched.

Parameters:

  • config (object): WebdriverIO configuration object
  • param (object[]): list of capabilities details

onWorkerStart​

Gets executed before a worker process is spawned and can be used to initialize specific service for that worker as well as modify runtime environments in an async fashion.

Parameters:

  • cid (string): capability id (e.g 0-0)
  • caps (object): containing capabilities for session that will be spawn in the worker
  • specs (string[]): specs to be run in the worker process
  • args (object): object that will be merged with the main configuration once worker is initialized
  • execArgv (string[]): list of string arguments passed to the worker process

onWorkerEnd​

Gets executed just after a worker process has exited.

Parameters:

  • cid (string): capability id (e.g 0-0)
