This Article covers HTTPS method PATCH, requests made to a REST API to update resources partially (Not Completely) at the URI end, and validate the response through Scriptworks.
In this article, we will perform a PATCH Request on Rest API to show update operation partially on resource end (Not Completely) and validate it through Scriptworks – A Visual Programming/low Code Automation tool.
First, I will demonstrate the exercise we need to perform, followed by practically demonstrating the Automation through Drag and Drop of relevant Blocks present in Scriptworks for achieving it.
HTTP Verb Discussed in this Article:-
PATCH:- HTTP Method PATCH is used to update resources, only those resources where updates are required from the user end, not the entire resource at the URI end. Generally, it is used to create subordinate resources.
Unlike PUT requests, PATCH requests are not idempotent.
Note – Here, We are using https://reqres.in/ to practice on REST API’s queries response validation.
1) Open any random browser, whether it is chrome, firefox, etc.
2) Navigate to https://reqres.in/
3) Perform Patch Request and validate the response code 200. Although Screenshot is the same as present in the PUT request, we will change the job role while doing it practically over scriptworks IDE for demonstration and understanding purpose.
Following are the Steps to Perform the above Exercise, including validation using Low Code Visual Programming in Scriptworks:-
Pre-requisite: Users should be able to login to Scriptworks via their Credentials, and his Scriptworks Client should be up and running.
To know more about Scriptworks Client and Selenium Standalone Server, please follow this Article.
1) Open Scriptworks on your system with your credentials and open the project where you want to perform the Automated validations on the REST API response.
2) Now click on the Block symbol present on the left side panel and then click on getting started
BlockSymbol → Getting Started → API Test
As we know, we are going to initiate an API test. So Drag and Drop “API Test” onto the Canvas After clicking on the Getting Started link.
3) Now, we will use the comment block to let others know what we will perform. For that, we are going to click on the search text box and write comments and hit return.
Search → Comment → Drag and Drop to Canvas
4) Now, we will drag and drop some basic blocks required for a REST API request.
For REST API Request, we need four basic things from Scriptworks.
i) REST Call Block
ii) Method Block
iii) URI Block
iv) Response Block
We have searched the comment block in step 3 similarly we have to do for required blocks and drag and drop them to canvas.
- Search → REST Call → Drag and Drop to Canvas
- Search → Method → Drag and Drop to Canvas
- Search → URI → Drag and Drop to Canvas
- Search → Body → Drag and Drop to Canvas
- Search → get Response → Drag and Drop to Canvas
Demonstrating Drag and Drop of Rest call Block to Canvas
Demonstrating Drag and Drop of Method Block into Canvas
By default, we would have GET as an HTTP verb. Please change it to PATCH by clicking the drop-down present in the method block.
Demonstrating Drag and Drop of URI Block into Canvas
In URI Block Enter “https://reqres.in/api/users/2”
Demonstrating Drag and Drop of Add Body Block into Canvas
Now enter the Payload inside the add body block.
It’s not that you have to enter your payload linearly always. Scriptworks provide you the outstanding feature of adding a multiline block that can be expanded to your query level. Let’s see that as well.
Click on Block symbol → Click on Input Values Link → Choose Multiline block → Drag and drop to Canvas.
Demonstrating Drag and Drop of get response Block into Canvas
5) Let’s give it a dry run and see what we are receiving in response after the run.
In the above screenshot, we can see what request we have sent to the Rest API query with the kind of request headers that have been passed.
In the above screenshot, we can observe how well scriptworks is capturing Rest API response.
6) Drag comment to let others know what we are going to do now. And for that, follow Step 3 Above.
Search → Comment → Drag and Drop to Canvas
7) Now, to validate the response, or we can say in technical terms, i.e., to Assert the API response received to Scriptworks. Drag Assert block multiple times to the number of Assertions you want, put it in Canvas, and fill it with information you wish to assert from the Rest API response.
Search → Assert → Drag and Drop to Canvas
We have added Assert Block. Now, what do we have to Assert?
We have to Assert the status code and message both from API Response. And for Getting API Response. We need a response body. So search for the response in the search box and pick the response body block and drag it into the canvas.
Search → Response → Drag and Drop Response Body into Canvas
As on PATCH Request, When Updation is done on the back end, we don’t get any message. So we are just capturing Year and validating that here.
8) Now, the final thing is Test Run. Make sure you have followed the prerequisite mentioned above before the Test Run. Make sure you can see Green Symbol before clicking on the play icon.
That’s how we can validate Rest API with their response code and status message in Scriptworks.
