How To Test With Playwright?

Running tests with Playwright is straightforward. Start with setting up your development environment and install Playwright. After that, you can write your test scripts in your preferred programming language and execute them using the Playwright test runner.

Here’s we are using JavaScript to write a test script:

Step 1: Install Playwright using the below command.

npm install playwright

Step 2: Write Your Test Script: Here we are taking JavaScript for a sample coding.


const { chromium } = require('playwright');

(async () => {

  // Launch a browser instance

  const browser = await chromium.launch();

  // Create a new page

  const page = await browser.newPage();

  // Navigate to a webpage

  await page.goto('https://example.com');

  // Perform actions such as clicking elements, filling forms, etc.

  await page.click('input[type="submit"]');

  await page.fill('input[type="text"]', 'Hello, Playwright!');

  // Capture a screenshot

  await page.screenshot({ path: 'example.png' });

  // Close the browser

  await browser.close();

})();

Step 3: Run Your Test Script: While running the test script, make sure you save the codes to a file and name it with the right extension. For example, here we used JavaScript, saving the file with the name of Test.js and running it using Node.js.

node test.js

Once you run and test this script, it will launch a Chromium browser. Navigate to https://example.com, click on a submit button, fill out a form, take a screenshot of the page, and then close the browser.

In addition, Playwright APIs allow you to write more complex test scenarios for specific conditions. It supports other browsers like Firefox and WebKit, which you can use by replacing Chromium with Firefox or Webkit in the above code.

Selenium: Definition and Measuring Automation Testing Abilities

Businesses looking for any automation web app testing tool that has long stood in the industry can consider Selenium. Originating in 2004 under the supervision of Jason Huggins, it stands as a venerable cornerstone in the realm of browser automation.

How To Run Test In Selenium?

Here we are explaining the simple example of running a test script using Selenium WebDriver in Python. Get an idea of how submitting a form with Selenium is simple. Also, you can consider hiring a mobile app developer in India to streamline the automation of web testing. 

Here’s a complete sample code command that helps you understand the testing process with Selenium:

from selenium import webdriver

from selenium.webdriver.common.keys import Keys

Initialize the Chrome WebDriver (ensure you have chromedriver installed and in your PATH)

driver = webdriver.Chrome()

Navigate to Google’s homepage

driver.get(“https://www.google.com”)

Find the search box element

search_box = driver.find_element_by_name(“q”)

Enter a search query

search_box.send_keys(“Selenium WebDriver”)

Simulate pressing the “Enter” key

search_box.send_keys(Keys.RETURN)

Wait for search results to load (you may need to add explicit waits for real-world scenarios)

driver.implicitly_wait(5)

Print the page title

print(“Page title:”, driver.title)

Find the first search result

first_result = driver.find_element_by_css_selector(“div.rc h3”)

Print the text of the first search result

print(“First search result:”, first_result.text)

Close the browser

driver.quit()

In this example:

  • We import the necessary modules from Selenium (webdriver for browser automation and Keys for simulating keyboard keys). 
  • Then initialize the Chrome WebDriver using webdriver.Chrome().
  • Next, navigate to Google’s homepage using driver.get(“https://www.google.com”).
  • Find the search box element on the page using its name attribute.
  • We enter a search query (“Selenium WebDriver”) into the search box using send_keys().
  • Then simulate pressing the “Enter” key using Keys.RETURN.
  • Next, wait for the search results to load using implicitly_wait().
  • Lastly, print the page title and the text of the first search result.
  • Finally, we close the browser using driver.quit().
  • You can save this script in a file (e.g., test.py) and run it using Python: python test.py

Make sure you have the necessary dependencies installed (Selenium and chromedriver) and that chromedriver is in your PATH.
