How to send POST requests in JMeter

How to send HTTP Request in JMeter?


We can perform GET as well as POST operations in JMeter. In this tutorial, we will only explain how we send POST HTTP requests in JMeter. In the previous tutorial, I explained how we can send GET request in JMeter.

Create a Test Plan in JMeter by following below-mentioned steps


Step 1 –  Add Thread Group

  • Select Test Plan on the tree
  • Add Thread Group                                                                                                                               To add Thread Group: Right-click on the “Test Plan” and add a new thread group: Add -> Threads (Users) -> Thread Group

In the Thread Group control panel, enter Thread Properties as follows: We will take an example of row no 5

Number of Threads: 5 – Number of users connects to the target website
Loop Count: 5  – Number of times to execute testing
Ramp-Up Period: 5 – It tells JMeter how long to delay before starting the next user. For example, if we have 5 users and a 5 -second Ramp-Up period, then the delay between starting users would be 1 second (5 seconds /5 users)

Step 2 –  Adding JMeter elements  

The JMeter element used here is HTTP Request Sampler. In HTTP Request Control Panel, the Path field indicates which URL request you want to send


Add HTTP Request Sampler
To add: Right-click on Thread Group and select: Add -> Sampler -> HTTP Request

Below-mentioned are the values used in HTTP Request to perform the test

  • Name – HTTP Request 
  • Server Name or IP – localhost
  • Port – 8000
  • Method – POST
  • Path – /demo/helloworld

Add HTTP Head Manager – The Header Manager lets you add or override HTTP request headers like can add Accept-Encoding, Accept, Cache-Control

To add: Right-click on Thread Group and select: Add -> Config Element -> HTTP Read Manager

Below mentioned are the values use in Http Request to perform the test
Content-type = application/json
accept – application/json

Step 3 – Adding Listeners to Test Plan


Listeners – They show the results of the test execution. They can show results in a different format such as a tree, table, graph, or log file
We are adding the View Result Tree listener

View Result Tree – View Result Tree show the results of the user request in basic HTML format
To add: Right-click Test Plan, Add -> Listener -> View Result Tree

Aggregate Report – It is almost same as Summary Report except Aggregate Report gives a few more parameters like, “Median”, “90% Line”, “95% Line” and “99% Line”.

 To add: Right Click on Thread Group > Add > Listener > Aggregate Report

Step 4 – Save the Test Plan

To Save: Click File Select -> Save Test Plan as ->Give the name of the Test Plan. It will be saved as .jmx format.

Step 5  – Run the Test Plan

Click on the Green Triangle as shown at the top to run the test.

Step 6 – View the Execution Status

Click on View Result Tree to see the status of Run. A successful request will be of Green color in the Text Section.

Click on Response data and Response Header to view other information about Response.

 

Click on Aggregate Report Result to see the aggregated status of Run.

  1. Hi Dheeraj. If you means to ask that in request body you want to pass different values something like this{ \”source\”:\”${SOURCE_NAME}\”, \”schema\”: \”star\”, \”service\”: \”windows\”}Yes, we can send different values by using Random Variable (Config Element) or getting different values in .csv and passing them to the request
