Suite of assertions that can be run on a CDK stack.

Typically used, as part of unit tests, to validate that the rendered CloudFormation template has expected resources and properties.

Example: 

 import software.amazon.awscdk.Stack;
 import software.amazon.awscdk.assertions.Template;
 Stack stack = new Stack();
 // ...
 Template template = Template.fromStack(stack);
