public class MigrateAxonTestFixtureFluentApi extends org.openrewrite.Recipe
Rewrites AF4 AggregateTestFixture test method bodies to the AF5 AxonTestFixture fluent given/when/then API.

AF5 split the flat AF4 fixture API (fixture.given(events).when(cmd).expectEvents(out)) into three sub-builders reached through no-arg phase methods: fixture.given().events(events).when().command(cmd).then().events(out). The leaf method names also changed (e.g. expectNoEvents → noEvents, expectSuccessfulHandlerExecution → success).

This recipe handles the mechanical chain rewrite. Rewrites applied:

  • given(e…) → given().events(e…)
  • givenCommands(c) → given().command(c) (single-arg); givenCommands(c1, c2…) → given().commands(c1, c2…) (multi-arg)
  • givenNoPriorActivity() → given().noPriorActivity()
  • when(cmd) / when(cmd, md) → when().command(cmd[, md])
  • expectEvents(e…) → then().events(e…)
  • expectNoEvents() → then().noEvents()
  • expectException(X.class) → then().exception(X.class)
  • expectException(X.class).expectExceptionMessage(m) → then().exception(X.class, m)
  • expectSuccessfulHandlerExecution() → then().success()
  • expectResultMessagePayload(p) → then().resultMessagePayload(p)
The fixture setup migration (new AggregateTestFixture<>(...) → AxonTestFixture.with(configurer), plus the @AfterEach fixture.stop() call) stays manual: the AF5 fixture takes an ApplicationConfigurer, which is project-specific. Hamcrest-matcher methods (expectEventsMatching, expectResultMessageMatching) are also left alone — the AF4 matchers don't translate mechanically to AF5's Consumer/Predicate-based eventsSatisfy / eventsMatch.
