run<R> method

R run<R>(R body(AssertableApplicationContext context))

Starts a context, passes it to body, closes it with close() when body returns, and returns what body returned.

A context that failed to start is passed too, instead of throwing: check it with hasFailed() or AssertableApplicationContext.startupFailure. For a body that awaits, use runAsync; here the context would be closed at the first await.

Implementation

R run<R>(R Function(AssertableApplicationContext context) body) {
  final assertable = _start();
  try {
    return body(assertable);
  } finally {
    assertable._close();
  }
}
