Getting Started With WebdriverIO Typescript Jasmine

What is WebdriverIO?

WebdriverIO is a progressive automation framework built to automate modern web and mobile applications. It simplifies the interaction with your app and provides a set of plugins that help you create a scalable, robust, and flakiness test suite. WebdriverIO is built on top of Selenium NodeJS bindings.

Webdriver IO is Open Source Framework managed by OpenJS foundation and follows W3 framework architectural standards

In Comparison with Selenium, WebdriverIO is better as it provides you a readymade framework with easy setup and configuration.

What Are the Key Features of Webdriverio?

Let’s discuss the advantages of using WebdriverIO in Test Automation.

Extendable: Adding helper functions, or more complicated sets and combinations of existing commands is simple and really useful.

Cross Browser Testing: WebdriverIO supports almost all different types of browsers including Safari, Chrome, Edge, Firefox, etc.

Cross-Platform Support: WebdriverIO is NodeJS based automation framework it supports all major Operating Systems including Mac and Windows. So, you can run your tests on different platforms and ensure your application is working as expected.

Native Mobile Application Support: WebdriverIO not only supports Web Applications but also supports Mobile applications so you can test all mobile applications by configuring accordingly.

Easy Set up: Setting up WebdriverIO is super easy; it’s just some package installation and then configuring the config file. We are going to show that in this tutorial.

Assertion Library Support: WebdriverIO supports major assertion libraries like Jasmine, Mocha, etc. This helps you to write your automation framework seamlessly.

Community Support: Community support for this WebriverIO is great; there are tons of articles and knowledge base available over the internet so that you can learn and enhance your own framework.

How to Set Up Webdriverio Typescript Framework From Scratch

In this detailed tutorial, we are going to explain how to set up the WebdriverIO (WDIO) Test Automation Project using Typescript and Jasmine with Page Object Model in an easy way.


Step 1: Creating a New Folder (Ex: WebdriverIOTypScript)

Navigate to any of your drives. Create a fresh new folder (Ex: WebdriverIOTypescript).

Step 2: Creating a Package.json for Your WebdriverIO Project

Create a pacakge.json file.

In your newly created Project Folder, open the command prompt and type:

npm init

The above command asks you a set of pre-defined questions. Just hit [Enter] [Enter] unless you wish to specify. Once everything is done, this will create pacakge.json a file in your Project Folder.

Step 3: Opening the Project Folder in Visual Studio Code IDE

In Visual Studio Code, click File > Open > Choose Newly Created Project Folder > Click on Select Folder.

Step 4: Installing the WebdriverIO Command Line Interface, Also Known as WDIO CLI

We have opened our project folder in Visual Studio Code IDE, so let’s start with the installation WebdriverIO. In order to install webdriverIO, we need to use npm pacakge @wdio/cli.

In your Visual Studio Code, Open Terminal.

 Navigate to Terminal menu >Click on New Terminal.

Enter the below command to install Webdriverio on your machine:

npm install - save-dev @wdio/cli

Wait for the Installation to finish!

Finishing the installation screenshot.

Step 5: Setting Up the WebdriverIO for Your End to End Test Automation Project

Once WeddriverIO is installed, we need to do the first-time setup of WDIO using the wdio config command.

From your Visual Studio Code Terminal, enter the below command:

npx wdio config

The command-line prompts for a set of Options Answer them like the below:

  • Where is your automation backend located? On my local machine.
  • Which framework do you want to use? Jasmine.
  • Do you want to use a compiler? TypeScript (https://www.typescriptlang.org/).
  • Where are your test specs located? ./test/specs/**/*.ts
  • Do you want WebdriverIO to autogenerate some test files? No.
  • Which reporter do you want to use? spec
  • Do you want to add a service to your test setup? Chrome driver.
  • What is the base URL? http://localhost

Step 5 screenshot.

If you look at the above point, we are installing WebdriverIO for our Test Automation project, Which uses Typescript, Jasmine

Once the above steps are complete, It will create a default configuration for you

Step 6: Creating the Directory Structure for the WebdriverIO Typescript Project

We are creating WebdriverIO, a Typescript project with a page object model, so we need to follow the correct folder structure as given below:

  • Create a Folder with name test in your root Project Folder.
  •  Under the test folder, create two folders: pages and specs.

The folder structure should look like the below:


Step 6 screenshot.

Step 7: Installing the Typescript and ts-node npm Packages for the WebDriverIO Project

In your Visual Studio Code Terminal, type the below command to install Typescript and ts-node:

npm install typescript ts-node --save-dev

Note: These packages should have been installed already if you choose Typescript Option during webdriver set up time. Just ensure it is installed correctly.

Step 8: Creating the tsconfig.json File for the WebdriverIO Project

Open Visual Studio Code Terminal, and type the below command:

npx tsc --init

The above will create a tsconfig.json file in your Project Root Directory.

Creating a file in the directory screenshot.

Step 9: Configuring the tsconfig.json File in the WebdriverIO Project

Remove the default generated code, and replace it with the below code in tsconfig.json:

  "compilerOptions": {
    "target": "es2019",
    "types": [
  "include": [

Step 10: Configuring the wdio.conf.ts File

The wdio.conf.ts file already has a lot of self-generated code, so we might not need all of those. You can copy and paste the below code:

export const config: WebdriverIO.Config = {
 specs: [
 capabilities: [{
        browserName: 'chrome', 
        maxInstances: 1,       
    framework: 'Jasmine',  
    jasmineOpts: {
        defaultTimeoutInterval: 120000,
    autoCompileOpts: {
        autoCompile: true,
        // for all available options
        tsNodeOpts: {
            transpileOnly: true,
            project: 'tsconfig.json'

Step 11: Writing Your First Page-Object File for the WebdriverIO Typescript Project

Let us try to create a Simple Google Search Test case.

Navigate to the tests folder, open the pages folder, and create a new file called example.page.ts.

So, the location of example.page.ts is test/pages/example.page.ts.

Add the below code:

class ExampleClass{
    get  searchInput() { return  $("input[name="q"]")}
    get searchButton() {return $('input[name="btnK"]')}
    get firstResult() {return $('(//h3)[1]')}
export default new ExampleClass()

Adding the code screenshot.

Step 12: Writing Your First Spec File for the WebdriverIO Typescript Project

Navigate to tests/specs/ ,and create new file called example.spec.ts

Copy and paste the below code into example.spec.ts:

import ExampleClass from "../pages/example.page"
describe('Google Search', () => {
  it('should search for sepcified text',async() => {
    await browser.url('https://www.google.com');
    await (await ExampleClass.searchInput).setValue("Webdriver IO Search Example");
    await browser.keys('Enter')
    await expect(await((await ExampleClass.firstResult).getText())).toContain("WebdriverIO")

Step 12, pasting the code screenshot.

Step 13: Executing the WDIO Typescript Tests

Once you have completed all the above tests, run your tests with the below command:

npx wdio run ./wdio.conf.ts

Step 14: WDIO Test Results in Console

Tests start executing, and you will see the results in the command line:

Issues You Might Face in Setting-Up WebdriverIO

Why is the Chrome Browser not launching in WebdriverIO?

This issue is mostly related to your configuration file, i.e wdio.conf.ts. Check your settings properly.

Why am I getting “.setText()? .click() is not a function in WebdriverIO?”

If you are using the async mode, usually you will get this; prefix your web element with await issue will be resolved.

Why is my WebdriverIO test not executing?

Sometimes there are a lot of Selenium Webdriver instances running, which might cause your tests to behave weirdly when you execute. You might have to restart the system or kill all the instances of the web drivers.
