send method

Future<TestResponse> send()

Send the HTTP request and return the response.

Constructs the complete HTTP request with all configured headers, body content, and authentication, then sends it to the server.

Example:

final response = await testApp.get('/api/users')
  .header('Accept', 'application/json')
  .send();

print('Status: ${response.statusCode}');
print('Body: ${response.body}');

Returns a TestResponse with the server's response. Throws TestException if the request fails due to network issues.

Implementation

Future<TestResponse> send() async {
  final uri = Uri.parse('$baseUrl$path');

  try {
    final request = await _client.openUrl(method, uri);

    // Set headers
    _headers.forEach((key, value) {
      request.headers.add(key, value);
    });

    // Set content type if specified
    if (_contentType != null) {
      request.headers.contentType = ContentType.parse(_contentType!);
    }

    // Write body if present
    if (_body != null) {
      String bodyString;

      if (_body is Map || _body is List) {
        if (_contentType == 'application/x-www-form-urlencoded') {
          // Form encode
          final formData = _body as Map<String, String>;
          bodyString = formData.entries
              .map((e) =>
                  '${Uri.encodeComponent(e.key)}=${Uri.encodeComponent(e.value)}')
              .join('&');
        } else {
          // JSON encode
          bodyString = jsonEncode(_body);
          if (_contentType == null) {
            request.headers.contentType = ContentType.json;
          }
        }
      } else {
        bodyString = _body.toString();
      }

      request.write(bodyString);
    }

    final response = await request.close();
    final responseBody = await response.transform(utf8.decoder).join();

    return TestResponse(response, responseBody);
  } catch (e) {
    throw TestException('Request failed: $e');
  }
