When a component is created, the framework tracks its lifecycle. When the test exits, any components that were
created during the test are automatically closed.

### Writing Components

To add a new component, you'll first need to create a top-level folder for your component under the
[components folder](https://github.com/istio/istio/tree/master/pkg/test/framework/components).

        when:
        project.components.add(component)

        then:
        project.components.size() == 1

        when:
        binaries.add(b1)
        binaries.add(b2)
        binaries.realizeNow()

        then:
        project.components.size() == 3
        project.components.b1 == b1
        project.components.b2 == b2
    }
