Can you test API with JMeter?

One of the most popular and simple tools to perform API Testing is the Apache JMeter.

How do you do a load testing on API?

To create a peak test:

  1. Use the Ramp Sequence or Variance load profile.
  2. Simulate the load that is close to the maximum expected load on the API, while providing some breathing space.
  3. Set a long test duration, for example, half a day.
  4. Create assertions and API monitors that will help you evaluate the API performance.

How do you automate a test in JMeter?

Automating JMeter and Selenium Tests

  1. Download Taurus.
  2. Build or import 2 scripts: One for Selenium that automates the browser, one for JMeter commands – for reaching scales.
  3. Run the test locally at first, to ensure it runs well before committing it.
  4. Now, run the tests in the cloud by adding -cloud to the command line.

How do I check my API performance?

Broadly speaking, API performance tests can be divided into two: functional and load tests.

  1. API Functional Tests.
  2. API Load Tests.
  3. Planning API Load Test Scenarios.
  4. Load Tests.
  5. Stress Tests.
  6. Soak Tests.
  7. Peak and Spike Tests.
  8. Endpoint vs.

What is API load testing?

It’s a way to check whether your application is robust enough to handle the load you want it to handle before your users find that out for you. API load testing is going through this process by simulating multiple users sending requests to your server at the same time.

How do I test my API server?

API test actions

  1. Verify correct HTTP status code. For example, creating a resource should return 201 CREATED and unpermitted requests should return 403 FORBIDDEN, etc.
  2. Verify response payload.
  3. Verify response headers.
  4. Verify correct application state.
  5. Verify basic performance sanity.

How do you test API performance?

Mocking Data Having the set of data as expected in real-time helps to validate the functionality and performance of the API. By using Postman workflow and collection runner features, actual application flow can be mocked and with the use of scripts, we can create the load for the functionalities which will be tested.

How do I test REST API performance?

If you need to load test you need to add your own server’s name.

  1. Add a Thread Group. Right Click -> Add- > Thread Group. Here we defined “Number of Threads = 50” and “Loop Count = 5”.
  2. Add a HTTP Request. Right Click on REST Example -> Add -> Sampler -> HTTP Request.
  3. Fill in the necessary values:

What is JMeter automation?
