Testing layered stacks about taskcat

[tonynv]

@sampritavh here is an example of how we handle dependancies via CFN. Let me know if that solves what you are trying to accomplish
Example https://github.com/aws-quickstart/quickstart-linux-bastion/blob/master/templates/linux-bastion-master.template#L306

CFN has the ability to enforce resource dependancies.
The example makes sure that the VPCStack completes before the App Stack launches. The main reason we suggest leveraging CFN vs. building in taskcat test dependancies is because users that execute the CFN will need to make sure that they deploy the stacks in order. If you wrap the template in a master using CFN nesting its programmatically handled.

If the user is deploying into an existing VPC they can simply deploy the app template and pass in the subnets that already exists.

Setting the resource order using DependsOn will also effect the order that CFN (inherently taskcat )deletes resources.

Let me know you thoughts.

@sampritavh any thoughts?

@avattathil Thanks for the example. We could definitely do this.
We will try the approach that you have suggested and will get back to you if we some across any potential issues.
