void expectJsonBody(RecordedRequest request, Map<String, dynamic> expectedJson)

Dynamic structural check validating matching key-values inside raw JSON payloads.

Implementation

void expectJsonBody(RecordedRequest request, Map<String, dynamic> expectedJson) {
  try {
    final bodyNormalized = request.bodyAsJson;
    if (bodyNormalized is! Map) {
      throw TestFailure('Assertion Failed: Body payload is not a JSON Map structure.');
    }

    expectedJson.forEach((key, val) {
      if (bodyNormalized[key] != val) {
        throw TestFailure(
          'Assertion Failed: JSON payload key mismatch.\n'
          'Key: "$key"\n'
          'Expected: $val\n'
          'Received: ${bodyNormalized[key]}',
        );
      }
    });
  } catch (e) {
    if (e is TestFailure) rethrow;
    throw TestFailure('Assertion Failed: Failed to parse body payload as JSON: $e');
  }
