flutter - 如何使用 integration_test 包在 Flutter 中使用 Multiple TestData 自动化登录功能？

Question

在flutter integration_testing 中是否有更好的方法来测试具有多个测试数据的简单登录功能，而不是为不同的测试数据集编写不同的测试用例。

测试用例：

1. '成功登录/注销'

2. '使用空的用户名和密码登录'

3. '只用空密码登录'

4. '仅使用空用户名登录'

5. '使用无效用户名、有效密码登录'

6. '使用无效密码登录，有效用户名'

以下尝试的方法涉及在测试用例中重复的大量冗余代码库？

setUpAll(() {});
setUp(() {});
tearDownAll(() {});
tearDown(() {});
