Introduction
Karate framework and Rest Assured are two popular automation testing frameworks used in the industry. Both these frameworks come with their pros and cons. However, in recent times, Karate has gained a lot of popularity among developers and testers. In this blog post, we will discuss the advantages of Karate framework over Rest Assured with clear step-by-step instructions.
What is Karate Framework?
Karate is an open-source, API testing framework that is written in Java. It is designed to help developers and testers work in a simple and efficient manner. Karate was developed by Peter Thomas, the co-founder of Intuit. Karate has become popular over time because it is powerful, easy to learn and easy to maintain.
Advantages of Karate Framework over Rest Assured
- Intuitive Gherkin syntax: Karate supports the Gherkin syntax, which makes it easy to write and read test cases in plain English. Rest Assured, on the other hand, uses a more traditional approach that involves writing test cases in Java code. Writing test cases in Gherkin syntax is great for collaboration, as it makes it easier for non-technical team members to read and understand the test cases.
- Built-in reporting features: Karate provides built-in HTML reports that give you detailed information about the test results. These reports include charts, tables, and graphs that make it easy to track the progress of your tests. Rest Assured, on the other hand, does not offer built-in reporting features. You need to use external libraries or tools to generate reports.
- Easy to set up and maintain: Karate does not require you to configure a lot of dependencies to get started. All you need is a Java Development Kit (JDK) installed on your system. Rest Assured, on the other hand, requires you to set up a lot of dependencies to get started. You need to install and configure the Selenium WebDriver, Apache POI, and other libraries to use Rest Assured.
- Supports both SOAP and REST APIs: Karate supports both REST and SOAP APIs out of the box. Rest Assured, on the other hand, only supports REST APIs. This means that if you need to test a SOAP API using Rest Assured, you need to use external libraries or tools.
- Built-in test data management: Karate provides built-in support for managing test data. You can define and manipulate test data using JSON or XML files. Rest Assured, on the other hand, does not provide built-in support for test data management. You need to use external libraries or tools to manage test data.
Step-by-step Guide
Now, let’s get started with setting up and writing a simple API test case using Karate.
Step 1: Installation
To get started with Karate, you need to have JDK 8 or higher installed on your system. You can download the latest version of JDK from the Oracle website. After installing JDK, follow these steps to install Karate:
- Open a command prompt or terminal
- Navigate to the folder where you want to install Karate
- Run the following command:
npm install -g karate - Wait for the installation to complete
Step 2: Writing a Test Case
Create a new folder named my-project and navigate into it. Inside the folder, create a new file named my-api.feature and add the following code:
Feature: Test My API
Scenario: Test the GET endpoint of My API
Given url 'https://jsonplaceholder.typicode.com/posts/1'
When method get
Then status 200
And match response.title == 'sunt aut facere repellat provident occaecati excepturi optio reprehenderit'
This test case will send a GET request to the URL specified in the Given statement and verify that the response status is 200. Additionally, it will match the title of the response with the expected value.
Step 3: Running the Test Case
To run the test case, open a command prompt or terminal, navigate to the my-project folder, and run the following command:
karate my-api.feature
This command will execute the test case and generate an HTML report in the target\surefire-reports folder.
