Karate UI Testing Example

Karate is an open-source framework that is used for testing web services and APIs. It is an easy-to-use tool that is based on Cucumber JVM and offers a cross platform testing solution. Karate provides a comprehensive test automation framework that is powerful and flexible, and it can be used for UI testing as well.

In this post, we will discuss a UI testing example using Karate, explaining its benefits in web development projects.

Getting started with Karate UI testing

For this example, we will be testing a simple registration form designed in HTML/CSS. This form contains different fields like first name, last name, email, password, and date of birth. We will simulate a user’s actions such as filling the form, submitting it, and verifying if the details provided are saved properly.

We will use Karate’s built-in Java-based syntax, which features scenarios and steps with a Given/When/Then structure.

Firstly, the browser needs to be launched. The following command should do the job:

„`karate.configure(‚driver‘, { type: ‚chrome‘, executable: ‚chromedriver‘})„`

This command sets up the driver configuration to launch in the Chrome web browser. For Firefox, the ‚type‘ value would be ‚geckodriver‘.

Let’s start with the login scenario. The syntax for this scenario is:

„`
Scenario: User Login
Given driver ‚https://www.example.com/login‘
And input(‚input[type=“email“]‘, ‚example@example.com‘)
And input(‚input[type=“password“]‘, ‚example123‘)
When click(‚button[type=“submit“]‘)
Then assert assertTrue(driver.url == ‚https://www.example.com/dashboard‘)
„`

These Karate commands are self-explanatory, where the user enters the email and password in the login form, clicks on the submit button, and then the dashboard URL is verified.

Performing tests on a registration form with Karate

As mentioned earlier, we will be testing a simple registration form with different inputs present in the form. We will start with creating a new account on the website.

Here’s the syntax to fill and submit the registration form:

„`
Scenario: Registration Form Submission
Given driver ‚https://www.example.com/register‘
And input(‚input[name=“firstName“]‘, ‚James‘)
And input(‚input[name=“lastName“]‘, ‚Anderson‘)
And input(‚input[type=“date“]‘, ‚1987-03-23‘)
And input(‚input[type=“email“]‘, ‚james.anderson@example.com‘)
And input(‚input[type=“password“]‘, ’secretpassword‘)
When click(‚button[type=“submit“]‘)
Then assert assertTrue(driver.url == https://www.example.com/success)
„`

The above example fills the form with the necessary user details, clicks on the submit button, and verifies if the redirect URL contains the success page.

FAQs on Karate UI Testing: Everything You Need to Know

Karate UI testing is a powerful tool in automation testing and has gained popularity in recent years. It is an open-source framework that allows testers to perform UI testing and functional testing in an agile and efficient manner. However, with its growing popularity, comes a lot of questions. In this guide, we’ll be answering some of the most frequently asked questions about Karate UI Testing to help you understand what it is, how it can be used, and its benefits.

What is Karate UI Testing?

Karate UI Testing is a type of testing that focuses on automating web-based user interfaces, ensuring their functionality is as expected. It is an extension of the Karate framework, popularly known for API testing, but with the ability to test frontend interfaces as well. With Karate UI, you can write tests in a simplified syntax that is easily readable while still being powerful enough to cover all aspects of functional testing.

How does Karate UI Testing work?

Karate UI Testing uses the Page Object Model (POM) as the foundation principle behind its testing. POM is an Object-Oriented Programming (OOP) design pattern that organizes the UI elements of a web page into a class. With Karate UI Testing, you can write your test cases using Gherkin syntax and map each step to the methods of the test class. This way, a single test can perform multiple operations on the web page.

What are the benefits of using Karate UI Testing?

Karate UI Testing has numerous benefits. First, it is an open-source framework, which means it’s free to use and integrate into your testing environment. Second, it allows testers to write tests in a simple and readable syntax, reducing the need for any specialized programming skills. Third, it provides quality feedback on the functionality of the website’s front-end in the form of a detailed report, saving valuable time for the development team. Lastly, because Karate UI Testing can be integrated with and extend an API suite, it can help testers gauge the end-to-end behavior of an application.

Is it necessary to have prior testing experience to use Karate UI testing?

It’s not necessary to have prior UI testing experience to use Karate UI Testing. Karate UI is designed to be user-friendly and testers can quickly get started with its simple and intuitive syntax. Users can quickly go to the project’s GitHub page, download the framework, and access extensive documentation and examples to get started with the testing suite.

What types of testing can I perform using Karate UI Testing?

The beauty of Karate UI Testing is that it allows testers to perform a variety of functional tests. Some tests you can perform using Karate include:

– Functional Testing: This test ensures that specific functions of the website are working as intended.
– Regression Testing: This test ensures that changes to the website have not affected its existing features.
– Integration Testing: This test ensures that the website integrates smoothly with other applications necessary for its operation.

3. Unzip the downloaded file.
4. Once unzipped, you can access the Karate JAR files that are necessary for running Karate tests.

Step 2: Set up your Project

After installing Karate, you are ready to set up your project. Create a new project in your preferred IDE and add the Karate JAR files to the project’s classpath. Once that is done, add the necessary dependencies to your project.

Step 3: Create a New Feature File

In Karate, all your test cases are written in feature files. Create a new feature file for your UI test by following these steps:

1. Create a new file with a „.feature“ extension.
2. Add the feature name in the format of „Feature: testing the login page.“
3. Add the different scenarios under the feature name you want to test.

Step 4: Write the UI Test Script

In Karate, writing a UI test script is very similar to writing a scenario in Gherkin syntax. Follow these guidelines:

1. Begin by writing a Scenario outline, adding the different variables you want to use.
2. Write the Given, When, and Then steps according to your UI test case.
3. Use the Karate DSL syntax to interact with the application; for example, clicking a button, inputting text in a field, and validating the outcome of events.

Step 5: Execute the Test

After writing the UI test script, the last step is to execute the test. There are two methods to execute the test:

1. Using the Karate Runner class to run the test individually from your IDE.
2. Use the Maven plugin to execute the tests as part of your build process.

Conclusion

Karate is an excellent framework for UI testing as it provides a straightforward way to write and execute tests without needing deep technical knowledge. The framework allows you to take advantage of the benefits of using a low-code test automation framework, while still being flexible enough to meet the needs of more complex testing scenarios. By following the above steps, you can get started with Karate and ensure that your application’s user interface is functional and user-friendly.
