Test export of datajson from the inventory-app instead of ckanext-datajson

[nickumia-reisys]

User Story

In order to work around difficulty with mocking non-string responses in the datajson extension, the data.gov team wants to implement a integration test for datajson export from the inventory app.

Acceptance Criteria

[ACs should be clearly demoable/verifiable whenever possible. Try specifying them using BDD.]

• GIVEN datasets are created within an organization on inventory app
  WHEN the organization data.json file is exported
  THEN a zip file is downloaded
  AND the parsed file contains the expected data.json file and metadata

Background

[Any helpful contextual notes or links to artifacts/evidence, if needed]

Due to the change in ckan tests, the TestExport class in ckanext-datajson will be re-implemented in inventory-app to validate this key use case

Original code is here.

Security Considerations (required)

None

Sketch

Implement with bats testing framework.
