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.
This BrowserStack Example repository demonstrates a WebdriverIO tests framework written in Mocha and nodeJS with parallel testing capabilities. The WebdriverIO test scripts are written for the open source BrowserStack Demo web application (Github). This BrowserStack Demo App is an e-commerce web application which showcases multiple real-world user scenarios. The app is bundled with offers data, orders data and products data that contains everything you need to start using the app and run tests out-of-the-box.
The WebDriverIO tests are run on different platforms like on-prem, docker and BrowserStack using various run configurations and test capabilities.
-
Clone the repository
-
Ensure you have the following dependencies installed on the machine
- NodeJS >= 14.16.0 (includes npm 6.14.11)
-
Run below command to configure dependencies
npm install
This repository contains the following WebdriverIO tests:
| Module | Test name | Description |
|---|---|---|
| E2E | End to End Scenario | This test scenario verifies successful product purchase lifecycle end-to-end. It demonstrates the Page Object Model design pattern and is also the default test executed in all the single test run profiles. |
| Login | Login with given username | This test verifies the login workflow with different types of valid login users. |
| Login | Login as Locked User | This test verifies the login workflow error for a locked user. |
| Offers | Offers for Mumbai location | This test mocks the GPS location for Mumbai and verifies that the product offers applicable for the Mumbai location are shown. |
| Product | Apply Apple Vendor Filter | This test verifies that the Apple products are only shown if the Apple vendor filter option is applied. |
| Product | Apply Lowest to Highest Order By | This test verifies that the product prices are in ascending order when the product sort "Lowest to Highest" is applied. |
| User | Login as User with no image loaded | This test verifies that the product images load for user: "image_not_loading_user" on the e-commerce application. Since the images do not load, the test case assertion fails. |
| User | Login as User with existing Orders | This test verifies that existing orders are shown for user: "existing_orders_user" |
For all the parallel run configuration profiles, you can configure the maximum parallel test threads by changing the settings below.
-
Docker
./resources/conf/wdio-docker-parallel.conf.jscapabilities: [{ maxInstances: 5, ...
-
BrowserStack
./resources/conf/wdio-bstack-parallel.conf.jscommonCapabilities: [{ maxInstances: 5, ...
This infrastructure points to running the tests on your own machine using a browser (e.g. Chrome) using the browser's driver executables (e.g. ChromeDriver for Chrome).
-
How to run the test?
To run the default test scenario (e.g. End to End Scenario) on your own machine, use the following command:
npm testTo run a specific test scenario, use the following command with the script names from package.json:
npm run <script_name>
For example:
npm run on-prem
where, the argument 'script_name' can be any WebdriverIO scenario name configured in this repository inside package.json.
-
Output
This run profile executes a specific test scenario on a single browser instance on your own machine.
-
How to run the test?
To run the entire test suite on your own machine, use the following command:
npm run on-prem-suite
-
Output
This run profile executes the entire test suite sequentially on a single browser, on your own machine.
-
How to run the test?
To run the entire test suite on your own machine in parallel, use the following command:
npm run on-prem-suite-parallel
-
Output
This run profile executes the entire test suite parallelly by opening multiple browser instances on your own machine.
Docker is an open source platform that provides the ability to package and test applications in an isolated environment called containers.
- Install and start Docker.
- Note: Docker should be running on the test machine. Ensure Docker Compose is installed as well.
-
How to run the test?
- To run the default test scenario (e.g. End to End Scenario) on your own machine, use the following command:
npm run docker
-
Output
This run profile executes a specific test scenario on a single browser deployed on a docker image.
-
How to run the test?
- To run the entire test suite in parallel on the docker image, use the following command:
npm run docker-parallel
-
Output
This run profile executes the entire test suite in parallel on a single browser, deployed on a docker image.
-
Note: By default, this execution would run maximum 5 test threads in parallel on Docker. Refer to the section "Configuring the maximum parallel test threads for this repository" for updating the parallel thread count based on your requirements.
BrowserStack provides instant access to 2,000+ real mobile devices and browsers on a highly reliable cloud infrastructure that effortlessly scales as testing needs grow.
-
Create a new BrowserStack account or use an existing one.
-
Identify your BrowserStack username and access key from the BrowserStack Automate Dashboard and export them as environment variables using the below commands.
- For *nix based and Mac machines:
export BROWSERSTACK_USERNAME=<browserstack-username> && export BROWSERSTACK_ACCESS_KEY=<browserstack-access-key>
- For Windows:
set BROWSERSTACK_USERNAME=<browserstack-username> set BROWSERSTACK_ACCESS_KEY=<browserstack-access-key>
Alternatively, you can also hardcode username and access_key objects in conf files releated to BrowserStack at
./resources/conf/file.
Note:
- We have configured a list of test capabilities in the files at
./resources/conf/. You can certainly update them based on your device / browser test requirements. - The exact test capability values can be easily identified using the Browserstack Capability Generator
In this section, we will run a single test on Chrome browser on Browserstack. To change test capabilities for this configuration, please refer to the capabilities object in ./resources/conf/wdio-bstack-single.conf.js file.
-
How to run the test?
- To run the default test scenario (e.g. End to End Scenario) on BrowserStack, use the following command:
npm run bstack-single
-
How to custom build and session names?
-
When you run test on BrowserStack it creates a build and session under which you can see your results. In this framework, if you want to add some custome name for build and session you can do like below:
-
Set build name by setting env varaibale:
- For *nix based and Mac machines:
export BROWSERSTACK_BUILD_NAME=<browserstack_build_name>
- For Windows:
set BROWSERSTACK_BUILD_NAME=<browserstack_build_name>
-
Set session name by command line aregument: You can do this while running test like below.
npm run bstack-single -- --bstack-session-name <session_name>
If you dont want to add, this framework will add build and session name with a time stamp for better tracking.
