Shared Specs

There are several shared example groups in valkyrie/lib/valkyrie/specs/shared_specs, to help verify that all implementations of the various interfaces are fully-compliant. You can also use these in your own code to make sure that any implementations you develop are compliant.

The available example groups are:

• 'a Valkyrie::DerivativeService'
• 'a Valkyrie::FileCharacterizationService'
• 'a Valkyrie::MetadataAdapter'
• 'a Valkyrie::Resource'
• 'a Valkyrie::Persister'
• 'a Valkyrie query provider'
• 'a Valkyrie::StorageAdapter'

To use these shared examples, include them in your test file:

require 'valkyrie/specs/shared_specs'

and then you can use the it_behaves_like command to invoke the shared examples:

it_behaves_like "a Valkyrie::Resource"

Example groups typically require that the calling test define a variable, e.g., the 'a Valkyrie::Model' group requires defining the resource_klass variable:

let(:resource_klass) { described_class }

The share examples will raise an error if the variables they need aren't defined.
