异步测试在Nunit 2.6.2中挂起(Async test hangs in Nunit 2.6.2)

异步测试在Nunit 2.6.2中挂起(Async test hangs in Nunit 2.6.2)

我有这个简单的测试方法如下。

[Test] public async Task OneSimpleTest1() { var eightBall = new EightBall(); var answer = await eightBall.WillIWin(); Assert.That(answer, Is.True); }

测试类看起来像这样

public class EightBall { public Task<bool> WillIWin() { return new Task<bool>(() => true); } }

我使用下面的命令在Nunit 2.6.2中运行测试。

nunit-console.exe EightBall.dll /framework:net-4.5

但是，测试似乎没有返回并永远挂起。 是否有一种特殊的方法可以使用Nunit 2.6.2运行异步测试。 我认为使用Nunit 2.6.2支持异步

I have this simple test method below.

[Test] public async Task OneSimpleTest1() { var eightBall = new EightBall(); var answer = await eightBall.WillIWin(); Assert.That(answer, Is.True); }

The test class looks like this

public class EightBall { public Task<bool> WillIWin() { return new Task<bool>(() => true); } }

I run the tests in Nunit 2.6.2 using the below command.

nunit-console.exe EightBall.dll /framework:net-4.5

However, the test does not seem to return and hangs forever. Is there a special way to run async tests with Nunit 2.6.2. I thought async was supported using Nunit 2.6.2

最满意答案

return new Task<bool>(() => true); 创建任务但不启动它。 更好的使用return Task.Run(()=> true); 或者return Task.FromResult<bool>(true)

您也可以将代码更改为

public Task<bool> WillIWin() { var task = new Task<bool>(() => true); task.Start(); return task; }

使它工作

return new Task<bool>(() => true); creates a task but does't start it. Better use return Task.Run(()=> true); or return Task.FromResult<bool>(true)

You can also change your code to

public Task<bool> WillIWin() { var task = new Task<bool>(() => true); task.Start(); return task; }

to make it work
