Essential Checklist for HTTP Requests in API Testing

 

This is an attempt to remind you what needs to be checked while sending and retrieving data from an HTTP request in API testing.



  1. Method - Ensure the appropriate method (GET, POST, PUT, DELETE, etc.) has been selected to send the request using any tools like Postman, SOAPUI, or Swagger.
  2. Host - The host plays a crucial role in hitting the exact server the user wants for the operation.
  3. Version of API - The version should be known before hitting the request. It helps to process the data in the deserved endpoint.
  4. Path - When the path is provided in the way where exact data is to be stored or updated, it reaches the destination correctly.
  5. Endpoint - It is the destination point. Though the entire direction is correct, if the request does not have an accurate endpoint, it leads to retrieving inappropriate data and is time-consuming.
  6. Request Payload - Payload is the data provided to the server to process the request correctly.
  7. Request Headers - It is crucial for communication between the client (Eg. Browser) and the server. Verify the request headers to understand the data flow if the system passes the valid data. Some of the commonly used headers are HTTP version, Accept, Accept-Language, User-Agent, Authorization, and Cache-Control.
  8. Response Status code - Verify the status code whether the exact code is displayed and whether the corresponding messages are delivered for easy understanding.
  9. Response data - Requested data should be processed and responded to by the client from the server without any malfunction or deviation from what was asked.
  10. What should I test? - Most importantly, one should know what should be tested based on the request. It relies on understanding the requirements and proper communication between the testers and others from the team.

How to Install Jenkins

Image
Jenkins is an open-source Java application server for Continuous Integration and Continuous Delivery (CI/CD). This will run in servlet containers such as Apache Tomcat. It helps the developers to build, test, and deploy the software by automating using CI/CD pipelines. It detects bugs and notifies the developers in an early stage. How to Download and Install: Step 1: Go to https://www.jenkins.io/ . Click Download Step 2: Download Jenkins ‘Generic Java package’. I prefer to download the LTS package (It is a stable one). Step 3: Select your desired path after downloading and save the Jenkins.war file in your local system. Step 4: Go to command prompt (Windows) | Terminal (IOS)                Go to the folder where the war file is saved. Then, type the command java -jar Jenkins.war and run it. It will take a while to run the command. It gives an admin password. Note it down to use Jenkins the first time. The password will be saved in the Jenkin path. Step 5: Go to the browse

HTTP Payloads

Image
 What happens when I send a letter without information to the receiver that I require some details from them? What happens when the receiver writes a response to my letter without having the information I need? This information is similar to the body generally called a payload in HTTP request and response.  Let us see the payload in the HTTP request and HTTP response individually. I have added the below image to explain the HTTP request and response body/payload in JSON. I have used BurpSuite to take this image and Swagger Petstore (petstore.swagger.io) for this example. HTTP Request Payload Generally, the payload is not required for all the requests and responses. GET and HEAD methods usually do not require a body while sending a request to the server. The above example is a POST request to create a resource name 'doggie'. To achieve this, I should send some information about the resource which is called HTTP request payload. Breakdown of request payload: Content-Type:  Specif

Variables in Postman

What is a variable? This is the basic question to learn when you start programming. I am not going to dive deep into the programming concepts. Let me explain the variables used in Postman. What is a Variable in Postman? A data unit, that stores a value and it is dynamic based on the data type we use.  Should be written as Key: Value pair (Example: name= "Test"; num=1;) Provides the facility to access the value without manual effort every time. There are 5 different scopes of variables used in Postman. Global Variables Environment Variables Collection Variables Data Variables Local Variables These variable scopes are specially designed to refer to values in the Postman tool. Global Variable:          When the variable is assigned globally, it has all the privileges of accessing anywhere in the workspace such as the Environment, Collection. Environment Variable:          It is limited within the specific environment where you can access data between collections. Collection Vari
