How do you do a load testing on API?

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.

What is load test scenario?

A load test scenario is a recipe for how many bots should run your scripts simultaneously in a load test. Each bot represents one human user. During the peak phase, bots run the script and repeat as long as there is time remaining in the test.

What is API load test?

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 you perform a load test?

Best Practices for Load Testing

1. Identify business goals.
2. Determine key measures for the application and web performance.
3. Choose a suitable tool.
4. Create a test case.
5. Understand your environment.
6. Run tests incrementally.
7. Always keep end-users in mind.

Why do I need a load test for my API?

You can use this load testing strategy to get a basis for your further load tests, or to assess how your API performs against service-level agreement (SLA). Your test should help you determine what response is normal for the API. You can then use these values to set up the assertion in other tests.

How to create the best load testing scenarios?

And create the proper load testing scenarios to simulate hits from your customers’ locations. Start with a small number of clients (1, 20, 50, 100 concurrent users / second). Try to increase the number of the clients gradually to understand how your API, Website or WebApp behaves. Run GET requests on your main website pages (top 5 web pages)

When to use peak testing for your API?

Use peak testing to check how your API works during the busiest periods. Peak testing is similar to soak testing, but with much heavier load and shorter duration. Use the Ramp Sequence or Variance load profile. You can also run a test with the Fixed load profile in parallel to simulate background load.

What’s the best way to test your API?

Set a very long test duration. Ideally, soak tests should run for more than a day Create assertions and API monitors that will help you evaluate the API performance. Use peak testing to check how your API works during the busiest periods. Peak testing is similar to soak testing, but with much heavier load and shorter duration.
