Introduction
We all like it when things are easy for us. Rest API is something like that. It is easy to learn and implement. We can easily import REST API with OpenAPI to Katalon studio by following some simple steps. Let us have a look at the steps and find out.
Import REST API with OpenAPI Specification 3.0
We know that REST API uses HTTP requests to access and use data. We can use that data again to create, delete, read and update the data types. There are some minimum requirements if we import REST API to Katalon Studio with OpenAPI Specification 3.0. Followed by that, there are some simple steps that we will take.
Requirements
These are the needed conditions for Importing REST API with OpenAPI Specification 3.0.
Katalon Studio Version: The user should have a minimum Katalon Studio Version of 7.7.0
Enterprise license: The user should have an Active License of Katalon Studio Enterprise.
Importing
Once the minimum requirements have been met, we will go ahead to look at the importing service definition process. There are two ways to do this. The first is the basic way, and the second is the Alternate way. We will take a look at both below.
Basic Way
This is the Primary way to import a service definition. We will do it with OpenAPI 3.0. The steps are as follows.
Step 1: First, we have to create or open an API project or a Web Service Project of choice.
Step 2: After the project has been created, we have to import the test request. To do this, we will click on the green logo at the top. After clicking on it, we will have a dropdown menu.
Step 3: In the dropdown menu, we will select the OpenAPI 3.0 option.
Alternate Way
Now let us look at the alternate way for the importing process. We will import a service definition by following the steps.
Step 1: In a similar fashion to the basic ways, we will create an open API/Web Service project here.
Step 2: Now, we will take a look at the Tests Explorer panel and right-click on Object Repository.
Step 3: Right-clicking on the Object Repository will open up a menu where we will navigate to Import>From OpenAPI 3. Then we select it.
Selecting Local File
After we are done with the above steps, it is time to select a local file.
Immediately after we click on the OpenAPI 3 option, a dialog box will pop up, asking us to select a local file.
Option 1
We can paste the directory of our OpenAPI 3.0 local file and click OK.
Option 2
We can click on Browse and select the local file and then click OK.
Result
As a result, Katalon Studio will load up the file. It will also generate the RESTful Test request as needed.
Frequently Asked Questions
How is OpenAPI different from Swagger?
The phrases OpenAPI and Swagger are synonymous. There are, however, distinctions. OpenAPI is a RESTful API architecture, while Swagger is a collection of SmartBear tools.
How to import test cases in Katalon Studio?
We have to select Tools > Utility > Import Test Artifact from the main menu. Choose the file we want to import. Then we will choose the test case import location we want. Then we will select the test object import location in the Import Test Artifacts window. After that, we select OK.
Which language should we choose for REST API?
JSON and XML are the two most preferred REST API protocols for transmitting and receiving data. JavaScript, Java, Python, and Ruby on Rails are all web programming languages that offer capabilities for parsing and dealing with XML and JSON.
