Welcome to the next presentation on API testing, in this presentation we continue our discussion on Using Karate For Restful API Testing.  We begin with, an overview of what Karate is and where to find it.  Then, we take a comprehensive look at the Karate framework. In addition, we cover how to build continuous integration tests, integrate with other test frameworks like Cucumber, run,  and debug the tests.  Finally, we wrap up our discussion by showing you how to write Karate tests against a real-world scenario.

Using Karate For Restful API Testing Overview:

  • Overview of Karate
  • Karate Framework
  • Write Karate Unit Test

What is Restful API

REST APIs provide a flexible, lightweight way to integrate applications, and have emerged as the most common method for connecting components in microservices architectures.

HTTP Requests

  • Get – Requests a representation of the specified resource. Requests using GET should only retrieve data.
  • Post –Submits an entity to the specified resource, often causing a change in state or side effects on the server.
  • Put – Replaces all current representations of the target resource with the request payload.
  • Delete – Deletes the specified resource.

Karate

Karate is the only open-source tool to combine API test automation, mocks, performance-testing, and even UI automation into a single, unified framework. As a result, it also supports the BDD syntax popularized by Cucumber is language-neutral and easy for even non-programmers. In addition, Karate asl supports Assertions, HTML reports are built-in, and you can run tests in parallel for speed.

Start with a real-world example

To explain the principles of API testing we decided to begin with a real-world exercise and build out our test cases to support the following scenario. For instance, a company that wants to set up a Tutorial center at a university to help students study. Initially, they build a WS application that records the subjects that will be covered.

The current interface supports:

  • Create A Tutorial
  • Retrieve All Tutorials
  • Retrieve A Tutorial By Id
  • Update A Tutorials By Id
  • Find All Published Tutorials
  • Find By Title Containing String
  • Delete A Tutorial
  • Delete All Tutorials

Finally, this series comes from our mentoring/mastermind classes.  These classes are virtual meetings that focus on how to improve our technical skills and build our businesses.  After all the goals of each member vary.  However, this diversity makes for great discussions and a ton of educational value every time we meet.  We hope you enjoy viewing this series as much as we enjoy creating it.  As always, this may not be all new to you, but we hope it helps you be a better developer.
