title: Testing YAML Blueprints layout: website-normal children:
Brooklyn provides a selection of basic test entities which can be used to validate Blueprints via YAML. These are divided into two groups; structural, which effect the order in which child entities are started; and validation, which are used to confirm the application is deployed as intended.
Structural test entities include:
TestCase - starts child entities sequentially.ParallelTestCase - starts child entities in parallel.Validation test entities include:
TestSensor - perform assertion on a specified sensor.TestEffector - invoke effector on specified target entity.TestHttpCall - perform assertion on response to specified HTTP GET Request.SimpleShellCommandTest - test assertions on the result of a shell command on the same node as the target entity.The following sections provide details on each test entity along with examples of their use.
