Question

我正在尝试为我的应用程序设置Flutter Driver测试，并且该应用程序异步运行，所以我发现https://github.com/flutter/flutter/issues/41029表示您需要做的就是添加await driver.waitUntilFirstFrameRasterized();并且它应该可以工作，但是这确实会停止失败失败的测试根本无法运行。

该应用程序只是挂在初始屏幕上，甚至从未进入应用程序本身。

据我所知，这是我运行测试所需的全部设置

  FlutterDriver driver;
  // Connect to the Flutter driver before running any tests.
  setUpAll(() async {
    driver = await FlutterDriver.connect();
    await driver.waitUntilFirstFrameRasterized();

    // await Directory('screenshots').create();
  });

  // Close the connection to the driver after the tests have completed.
  tearDownAll(() async {
    if (driver != null) {
      await driver.close();
    }
  });

但是，我在终端中得到的只是以下输出：

VMServiceFlutterDriver: Connecting to Flutter application at http://127.0.0.1:54264/tt9kN4jBSrc=/
VMServiceFlutterDriver: Isolate found with number: 2942164624858163
VMServiceFlutterDriver: Isolate is paused at start.
VMServiceFlutterDriver: Attempting to resume isolate
VMServiceFlutterDriver: Connected to Flutter application.
VMServiceFlutterDriver: waitForCondition message is taking a long time to complete...

我已经离开它几分钟了，什么也没发生，我已经禁用了Firebase初始化，以防万一某种原因阻止了它，因为我需要接受警报对话框，而不是我能看到的那么远。 / p>

原来我也需要使用IsolatesWorkaround

  FlutterDriver driver;
  IsolatesWorkaround workaround;
  // Connect to the Flutter driver before running any tests.
  setUpAll(() async {
    driver = await FlutterDriver.connect();
    workaround = IsolatesWorkaround(driver);
    await workaround.resumeIsolates();
    await driver.waitUntilFirstFrameRasterized();

    if (!await Directory('screenshots').exists()) {
      await Directory('screenshots').create();
    }
  });

  // Close the connection to the driver after the tests have completed.
  tearDownAll(() async {
    await driver?.close();
    await workaround.tearDown();
  });
