Testing Complex Scenarios In Playwright Automation Testing

Playwright Automation Testing

As software development advances rapidly, automation testing has become increasingly essential to ensure that software applications are robust, reliable, and error-free. However, testing complex scenarios can be challenging, especially when testing web applications with multiple user interactions, complex workflows, and numerous integration points. This is where Playwright, an open-source Node.js library, comes in. 

With its ability to handle complex web interactions, Playwright has emerged as a powerful tool for automating end-to-end testing of modern web applications. In this article, we’ll explore how Playwright can help you test complex scenarios in automation testing and why it has become the go-to solution for developers and testers.

What Challenges are Involved in Testing Complex Scenarios, and How can Playwright Help Overcome Them?

There are several aspects to consider when testing complex scenarios in Playwright testing.

This section will explore some key challenges in testing complex scenarios and how Playwright can help overcome them. Some of the common challenges include:

  1. Multiple steps: Complex scenarios often involve multiple steps, making it difficult to test each step individually and ensure they work together seamlessly.
  1. Dynamic elements: Web applications are dynamic, which means that elements on a page can change depending on user interactions or other factors. This can make it challenging to locate and interact with elements using traditional testing methods.
  1. Cross-browser compatibility: Different browsers can display web pages differently, which can cause issues with functionality and layout. Testing complex scenarios across multiple browsers can be time-consuming and challenging.
  1. Data management: Complex scenarios often involve manipulating large amounts of data, which can be challenging to manage and manipulate in a testing environment.

Playwright can help overcome these challenges by providing a powerful and flexible API that allows testers to interact with web applications at a granular level. Some of the key features of Playwright that can help with testing complex scenarios include:

  1. Ability to automate multiple steps: Playwright allows testers to automate complex scenarios by creating scripts that perform multiple actions in sequence. This can help ensure that all steps of the scenario are tested and verified.
  1. Intelligent waiting: Playwright provides methods to wait for elements to appear on the page, which can help overcome issues with dynamic elements. This ensures that scripts interact with the correct elements at the correct time.
  1. Cross-browser compatibility: Playwright supports multiple browsers, including Chrome, Firefox, and Safari. This allows testers to easily test complex scenarios across multiple browsers, ensuring that functionality is consistent across all platforms.
  1. Data management: Playwright provides methods to interact with data, including filling in forms and submitting data. This can help testers manage large amounts of data and ensure that it is entered correctly.

Testing Complex Scenarios In Playwright Automation Testing

To demonstrate how Playwright can be used to test complex scenarios in automation testing, let’s consider an example of testing an e-commerce website that allows users to add items to their cart, update the cart, and checkout. We will create a Playwright test script to test this scenario, explaining each step along the way.

First, we need to set up the test environment by installing Playwright and creating a new test file. We can do this using the following commands:

npm install Playwright –save-dev

touch cart.test.js

Once we have set up the test environment, we can begin writing our test script. The first step is to launch the browser and navigate to the e-commerce website’s homepage. We can do this using the following code:

In this code, we launch a new Chromium browser, create a new browser context, and navigate to the homepage of the e-commerce website using the ‘goto’ method.

Next, we need to add an item to the cart. We can do this by clicking the “Add to Cart” button on the product page. We can locate the button using its CSS selector and click it using the following code:


Once we have added an item to the cart, we need to verify that it has been added correctly. We can do this by navigating to the cart page and verifying that the item appears in the cart. We can navigate to the cart page using the following code:

await page.goto(‘’);

To verify that the item has been added to the cart, we can check for the presence of the item’s name and price using the ‘textContent’ method.

In this code, we use the ‘waitForSelector’ method to wait for the cart item to appear on the page. We then use the ‘$eval’ method to extract the item’s name and price from the DOM and use Jest’s ‘expect’ method to verify that they are correct.

Next, we need to update the cart by changing the quantity of the item. We can do this by selecting the quantity dropdown and clicking the appropriate option:



In this code, we first click on the quantity dropdown to open the dropdown menu and then click on the option with a ‘data-value’ attribute of “2” to set the quantity to 2.

Finally, we need to proceed to checkout and verify that the checkout process completes successfully. We can do this by clicking the “Checkout” button, filling out the checkout form, and submitting the form:

In this code, we use the click method to click on the “Checkout” button, and then use the ‘fill’ method to fill out the checkout form with the required information. We then click the “Submit” button and wait for the page to navigate to the confirmation page using the waitForNavigation method. Finally, we use Jest’s ‘expect’ method to verify that the URL of the page is the confirmation page.

By following these steps, we have created a Playwright test script that tests a complex scenario involving adding an item to the cart, updating the cart, and completing the checkout process. This script verifies that each step of the process works correctly, ensuring that the e-commerce website is functioning as expected.

Let’s consider an even more complex scenario for testing an e-commerce website. Let’s say that we want to test the following user journey:

  1. User logs in to the website.
  2. The user searches for a product using the search bar.
  3. The user filters the search results by category.
  4. The user adds a product to their cart.
  5. The user applies a coupon code to their cart.
  6. The user proceeds to checkout and completes the purchase.

To test this scenario, we can use Playwright to automate each step of the process. Here’s an example of what the test code might look like:

Let’s go through each step of the code to understand what’s happening.

In the ‘beforeAll’ hook, we launch a new Chromium browser instance that will be used for all the tests in this suite.

In the ‘beforeEach’ hook, we create a new browser context and a new page instance for each test. We also navigate to the website’s homepage using the ‘goto’ method.

In the ‘afterEach’ hook, we close the browser context to ensure that each test starts with a clean slate.

In the ‘afterAll’ hook, we close the browser instance to ensure that it is properly shut down when all tests have finished running.

The ‘it’ block contains the test code that will be executed. We start by logging in to the website using the click, fill, and submit methods to interact with the login form.

Next, we use the ‘fill’ method to enter a search term into the search bar and press the “Enter” key using the ‘press’ method to submit the search query. We then use the ‘click’ method to interact with the category dropdown and select the “electronics” category.

After filtering the search results, we use the ‘waitForSelector’ method to wait for a product element to appear on the page and then use the ‘click’ method to add it to the cart.

Next, we navigate to the cart page using the ‘click’ method and apply a coupon code using the ‘fill’ method and the “Apply” button using the ‘click’ method.

Finally, we click the “Checkout” button and fill out the checkout form using the ‘fill’ method. We then use the ‘click’ and ‘waitForNavigation’ methods to submit the form and wait for the confirmation page to load. Finally, we use Jest’s ‘expect’ method to verify that the URL of the page is the confirmation page.
