-## Assertions
-
-When writing integration tests, you sometimes need to perform actions against the deployed integration test
-infrastructure to validate that certain functionality is working. This module contains assertion constructs
-that allow you to accomplish this.
-
-### Example
-
-The `aws-stepfunctions-tasks` module contains some good examples of when integration tests need to perform assertions
-on the deployed infrastructure. The `EventBridgePutEvents` construct creates a step function task to send and event
-to and EventBridge event bus. We are creating an integration between two different AWS services, so it is not enough
-to just assert that the infrastructure is successfully created, we also need to assert that the integration was configured
-correctly to allow the step function task to send the event to event bridge.
-
-Given an Integration Test that looks like this:
-```ts
-const app = new App();
-const stack = new Stack(app, 'aws-stepfunctions-tasks-eventbridge-put-events-integ');
-
-const eventBus = new events.EventBus(stack, 'EventBus', {
-  eventBusName: 'MyEventBus1',
-});
-
-const putEventsTask = new stepfunctions_tasks.EventBridgePutEvents(stack, 'Put Custom Events', {
-  entries: [{
-    // Entry with no event bus specified
-    detail: sfn.TaskInput.fromObject({
-      Message: 'Hello from Step Functions!',
-    }),
-    detailType: 'MessageFromStepFunctions',
-    source: 'step.functions',
-  }, {
-    // Entry with EventBus provided as object
-    detail: sfn.TaskInput.fromObject({
-      Message: 'Hello from Step Functions!',
-    }),
-    eventBus,
-    detailType: 'MessageFromStepFunctions',
-    source: 'step.functions',
-  }],
-});
-
-const sm = new sfn.StateMachine(stack, 'StateMachine', {
-  definition: putEventsTask,
-  timeout: cdk.Duration.seconds(30),
-});
-
-new IntegTest(app, 'IntegTest', {
-  testCases: [
-    new IntegTestCase(app, 'TestCase', {
-      stacks: [stack],
-    }),
-  ],
-});
-```
-
-We could then register assertions
-
-```ts
-const assert = new DeployAssert(
-  stack,
-);
-
-// Start an execution
-const start = assert.queryAws({
-  api: 'startExecution',
-  service: 'StepFunctions',
-  parameters: {
-    stateMachineArn: sm.stateMachineArn,
-  },
-});
-
-// describe the results of the execution
-const describe = assert.queryAws({
-  api: 'describeExecution',
-  service: 'StepFunctions',
-  parameters: {
-    executionArn: start.getAttString('executionArn'),
-  },
-});
-
-// assert the results
-assert.registerAssertion(describe.assertEqual({
-  status: 'SUCCEEDED',
-}, 'success'));
-```
