使用WebApplicationFactory运行集成测试时抛出的CancellationTokenSource已丢弃在测试类清除中

Question

我有一些Web Api Controller测试。这些都是使用.NET Core Tests提供的WebApplicationFactory构建的。

• 当我逐一运行这些Controller测试时，它们全部通过。
• 当我一次运行所有Controller测试时（在Visual Studio中，右键单击“测试项目”，然后选择“运行测试”），所有测试都会失败，但随机会失败。

打印屏幕1 ：全部成功

打印屏幕2 ：全部失败，但以下一项除外：

所有测试都包含一个[Theory]，该参数传入MemberData以测试各种安全组合。

subDoc

我在Dotnet运行时项目Github issue上找到了here。但是，我不确定是否是同一问题。另外，我似乎无法解决该问题。

有人对此有经验吗？我现在可以手动运行这些测试，但它也将是DevOps上CI管道的一部分。我想它也会在那里破裂。

非常感谢。

const names=[{ name: 'Apple' },{ name: 'Apricot' },{ name: 'Avocados' },{ name: 'Almond' },
        { name: 'Blueberries' }, { name: 'Bing Cherry' },{ name: 'Breadfruit' },{ name: 'Bananas' },
        { name: 'Cherries' },{ name: 'Custard-Apple' },{ name: 'Carrot' },{ name: 'Cranberries' },
        { name: 'Dates' }, { name: 'Dragon Fruit' },{ name: 'Durian' },
        { name: 'Grapefruit' },{ name: 'Grapes' },{ name: 'Gooseberries' },{ name: 'Guava' }]

const alphabets = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L',
  'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z'
];


const x = alphabets.map(x => ({
  [x]: [...names.filter(name => name.name.startsWith(x)).map(m => m.name)]
}));

console.log(x);

编辑：CI结果

正如预期的那样，Azure DevOps CI管道也遇到此问题。以下是日志/结果：
