15. Karate Framework || Interview Assessment Question.
In Karate DSL, scenarios are written in a very specific format that includes a keyword for each step of the scenario. For example, a scenario might start with the keyword *Given* to set the stage, followed by the keyword *When* to describe the action that takes place, and then the keyword *Then* to describe the expected outcome.
Karate is a newer framework that is designed specifically for testing web services. It is built on top of Cucumber, so it shares many of the same features. However, it is also designed to be easier to use and more concise. It also has built-in support for performance testing. So, if you are looking for a framework to test web services, Karate would be a good choice.
There are no real limitations, but there are some practical considerations. For example, you wouldn’t want to try to serialize an entire database into JSON and send it to the server. That would be way too much data and would probably overwhelm the server. So, while there are no technical limitations, you do need to use some common sense when deciding what to serialize into JSON.
One common mistake is not reading the documentation carefully. The Karate Framework is very powerful, but it is also complex. As a result, it is easy to make mistakes if you do not take the time to understand how it works. Another common mistake is not using the proper tools when working with Karate. For example, many developers try to use Karate with JUnit, but this is not the recommended approach. Finally, some developers try to use Karate for tasks that it is not well suited for, such as performance testing.
The Karate framework is built on top of Cucumber and HttpClient, and it uses the Java programming language. The framework is designed to make it easy to write tests for web services, and it includes a number of features that make it well-suited for testing RESTful services. One of the key features of Karate is that it allows tests to be written in a concise and readable syntax.

How to send an HTTP Request (Get, Post, Put, Delete, Patch)
In the above example, AM_USERNAME, AM_PASSWORD, AM_HOST, and AM_AUTHENTICATE_PATH come from the karate-config.js file.
‘’ can be interpreted as any of Given, When, Then, And, but when an action doesn’t serve a context, we can use ‘’.
’+’ acts as a concatenate operator
The above example sends an empty post body request. We can just use ‘ ‘
The method can be any valid HTTP verb (Get, Post, Put, Patch, Delete)
‘def’ is used to store a value in a variable.
header, url, request, method, status, response are all karate’s keywords forming the DSL. For the full list of keywords, visit Intuit.
In the above example, the response is JSON format, so we can use karate’s builtin JsonPath notation to parse the response.
