Key Features

• OpenAPI-driven: Automatically validate requests and responses against your OpenAPI spec

• BDD-style scenarios: Write readable tests using a Gherkin-like DSL

• Auto-generated tests: Automatically generate invalid request and security tests from OpenAPI schemas

• JUnit 6 integration: Seamless integration with your existing test infrastructure

• Spring Boot support: Auto-discover bindings and configuration from Spring context

• Plugin system: Extend functionality with custom plugins for reporting, logging, and more

• Custom steps: Define reusable step definitions with annotations, DSL, or registration API

• Multi-spec support: Work with multiple OpenAPI specifications in a single test suite

• Fragments: Create reusable scenario steps that can be included across tests

Quick Example

@IncludeEngines("berrycrush")
@BerryCrushScenarios(locations = ["scenarios/pet-api.scenario"])
@BerryCrushSpec(paths = ["petstore.yaml"])
@BerryCrushConfiguration(bindings = PetStoreBindings::class)
class PetApiTest

Scenario file (pet-api.scenario):

scenario: List all pets
  when: I request all pets
    call ^listPets
  then: pets are returned
    assert status 200
    assert schema
