class heat_integrationtests.functional.test_instance_group.InstanceGroupBasicTest(*args, **kwargs)

Bases: heat_integrationtests.functional.test_instance_group.InstanceGroupTest

test_basic_create_works()

Make sure the working case is good.

Note this combines test_override_aws_ec2_instance into this test as well, which is: If AWS::EC2::Instance is overridden, InstanceGroup will automatically use that overridden resource type.

test_create_instance_error_causes_group_error()

Test create failing a resource in the instance group.

If a resource in an instance group fails to be created, the instance group itself will fail and the broken inner resource will remain.

test_size_updates_work()

test_update_group_replace()

Test case for ensuring non-updatable props case a replacement.

Make sure that during a group update the non-updatable properties cause a replacement.

test_update_instance_error_causes_group_error()

Test update failing a resource in the instance group.

If a resource in an instance group fails to be created during an update, the instance group itself will fail and the broken inner resource will remain.
