Introduction
In web development, comprehensive automated testing plays a crucial role in ensuring the quality and reliability of applications.
Playwright, a versatile end-to-end testing framework, empowers developers to automate web interactions and verify the behaviour of their applications under various conditions.
This blog post delves into the process of utilising Playwright to test dropdowns, textboxes, and checkboxes in TypeScript, demonstrating its effectiveness in handling a wide spectrum of user interactions.
Testing Dropdowns with Playwright
Dropdowns serve as essential components for user input, allowing users to select from predefined options. Playwright simplifies the task of testing dropdowns by providing robust methods for interacting with these elements.
Let’s explore an example of testing a dropdown that displays a list of countries:
const dropdown = browser.findByLabelText('Select Country');
dropdown.click();
dropdown.selectOption('United States');This code snippet first locates the dropdown using the findByLabelText method, passing the label text “Select Country”. Next, it triggers a click event on the dropdown element. Finally, it selects the option “United States” from the dropdown list.
Testing Textboxes with Playwright
Textboxes allow users to enter and modify text input. Playwright offers straightforward methods for interacting with textboxes, enabling developers to validate user input and ensure its accuracy.
Consider an example of testing a textbox that prompts users to enter their name:
const textbox = browser.findByLabelText('Enter Name');
textbox.type('John Doe');This code snippet locates the textbox using the findByLabelText method, passing the label text “Enter Name”. Then, it types the text “John Doe” into the textbox.
Testing Checkbox with Playwright
Checkboxes enable users to toggle between selecting or deselecting options. Playwright provides efficient methods for managing checkbox interactions, allowing developers to verify checkbox states and ensure proper functionality.
Here’s an example of testing a checkbox that indicates the user’s agreement to the terms and conditions:
const checkbox = browser.findByLabelText('I agree to the terms and conditions');
checkbox.check();This code snippet locates the checkbox using the findByLabelText method, passing the label text “I agree to the terms and conditions”. Then, it triggers a check event on the checkbox, effectively selecting the option.
Combining Dropdown, Textbox, and Checkbox Testing
In real-world scenarios, applications often involve a combination of dropdowns, textboxes, and checkboxes, requiring a more intricate testing approach. Playwright empowers developers to orchestrate complex test scenarios by utilising its declarative syntax and manipulation methods.
Consider an example of testing a form that includes a dropdown, textbox, and checkbox:
// Select the gender dropdown
const genderDropdown = browser.findByLabelText('Select Gender');
genderDropdown.click();
genderDropdown.selectOption('Male');
// Enter the user's name
const nameTextbox = browser.findByLabelText('Enter Name');
nameTextbox.type('John Doe');
// Check the agree checkbox
const agreeCheckbox = browser.findByLabelText('I agree to the terms and conditions');
agreeCheckbox.check();
// Submit the form
const form = browser.findByTagName('form');
form.submit();This code snippet demonstrates the ability to handle multiple input elements within a single test script. It selects the gender from the dropdown, enters the user’s name, checks the agree checkbox, and finally submits the form.
Conclusion
Playwright makes the process of testing dropdowns, textboxes, and checkboxes in TypeScript simple. Its straightforward syntax, flexible methods, and ability to handle complex scenarios make it an invaluable asset for developers seeking to ensure the quality and reliability of their web applications.
By leveraging Playwright’s capabilities, developers can automate a wide range of user interactions, enhancing their testing processes and delivering high-quality software.
