 A test represents a load test for your application. A test is attached to an Azure load testing resource. You can create a test in either of two ways:
 
 - Create a [test based on an existing JMeter script](./how-to-create-and-run-load-test-with-jmeter-script.md).
-- Create a [URL-based load test](./quickstart-create-and-run-load-test.md) (quick test). Azure Load Testing generates a corresponding JMeter script.

 - Load configuration to [scale out your load test](./how-to-high-scale-load.md) across multiple [test engine](#test-engine) instances.

 Azure Load Testing test engines abstract the required infrastructure for [running a high-scale load test](./how-to-high-scale-load.md). The test engines run the Apache JMeter script to simulate a large number of virtual users simultaneously accessing your application endpoints. When you create a load test based on a URL, Azure Load Testing automatically generates a JMeter test script for you. To scale out the load test, you can configure the number of test engines.
