It can therefore run on any environment / workstation that accepts a Java virtual machine, for example: Windows, Linux, Mac, etc. #1) Create a Test Plan #2) Add a thread group with the number of users as 1, Ramp-up period of 1 second, and Loop count as 5. There are many other tools for generating load for testing purposes, but JMeter is one of the most mature. We will cover approach & Practical testing example with deomstrations. These tests are performed either directly on the API or as a part of the integration testing. Then, select the HTTP Request element in the tree and edit the following properties (see Figure 4.6): Change the Name field to "Home Page". Next, we just need to add this folder to the path environment variable so that it's accessible from the command line. Here we defined "Number of Threads = 50" and "Loop Count = 5". I want to use the API provided by Apache JMeter to create and run test scripts from a Java program. Apache JMeter initial screen. Upload a CSV file with the below data: Next we choose what to test text response (body), code (status), headers, etc. Sample 5: Login test-Simple data writer. JMeter is a free open-source Java software, used for functional API testing although it is primarily designed to load test functional behavior and measure performance. The first step is to go to the Apache JMeter folder. First, we define the base URL. Define the Invoked Action You now have to instruct JMeter on which action should be performed by the simulated users. Go inside the bin folder. When the JMeter is executed, it displays a green box at the right end pane under the menu bar. The Json extractor is perfectly working. For example, if we have 64 users and a ramp-up period of 100 seconds, JMeter would add a delay of 100 / 64 seconds between each user's first request.

You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. In this JMeter tutorial, we will load test the demo we always use at BlazeMeter, which simulates a mock travel agency named Simple. For example, if we have 100 users and a 100-second Ramp-Up period, then the delay between starting users would be 1 second (100 seconds /100 users) Step 2) Adding JMeter elements Now we determine what JMeter elements in this test. API Load Testing Using JMeter Let's take an Example - Suppose we have to test the load for 100 users who can concurrently use the API /API/getBusinessTypes for getting requests to fetch the total number of business types Steps Go to the Apache JMeter folder >> bin folder >> open the batch file>>select the Test Plan. The following image shows an example of an API call provided by OpenWeatherMap website. The Simple Test plan of JMeter is that one user is hitting only one API/request.
