我的 app_test.dart 代码

import 'package:flutter_driver/flutter_driver.dart';
import 'package:test/test.dart';`


void main() {
group("Flutter Auth Test", () {
  final emailField = find.byValueKey("emailfield");
  final passwordField = find.byValueKey("passwordfield");
  final signbutton = find.byValueKey("log");
  final adminPage = find.byValueKey("home");
  final userPage = find.byValueKey("userp");

  FlutterDriver driver;
  setUpAll(()async{
    driver = await FlutterDriver.connect();
  });

  tearDownAll(()async{
    if(driver != null) {
      driver.close();
    }
  });

  test("login with incorrect email and password",() async{
    await driver.tap(emailField);
    await driver.enterText("test@gmail.com");
    await driver.tap(passwordField);
    await driver.enterText("test123");
    await driver.tap(signbutton);
    await driver.waitUntilNoTransientCallbacks();
    assert(adminPage == null && userPage == null);
  });

  test("login admin with correct email and password",() async {
    await driver.tap(emailField);
    await driver.enterText("madhuwanthiaah@gmail.com");
    await driver.tap(passwordField);
    await driver.enterText("admin123");
    await driver.tap(signbutton);
    assert(adminPage != null && userPage == null);

  });

  test("login user with correct email and password",() async {
    await driver.tap(emailField);
    await driver.enterText("cst16029@gmail.com");
    await driver.tap(passwordField);
    await driver.enterText("user123");
    await driver.tap(signbutton);
    assert(userPage != null && adminPage == null);
  });
});
}

我解决了更新我的包并运行的问题， flutter drive --target=test_driver/app.dart 命令。 这个对我有用。我使用 android 模拟器进行此测试。
