unit-testing - 多次运行 NUnit 测试

Question

我有一套 NUnit 测试，其中一些测试间歇性失败，可能是因为计时问题。我想找到这些不稳定的单元测试。有没有办法多次重复每个测试，而不必在每个测试上放置 Repeat() 属性？我们通常使用 resharper 和 ncrunch 运行程序，但也可以访问 nunit gui 和控制台运行程序。

Answer 1

N单元3

在 NUnit 3 中，您可以使用 Retry属性:

RetryAttribute is used on a test method to specify that it should be rerun if it fails, up to a maximum number of times.

Notes:

It is not currently possible to use RetryAttribute on a TestFixture or any other type of test suite. Only single tests may be repeated.

If a test has an unexpected exception, an error result is returned and it is not retried. Only assertion failures can trigger a retry. To convert an unexpected exception into an assertion failure, see the ThrowsConstraint.

NUnit 2 不支持重试，但您可以使用 NUnit-retry 插件( NuGet 、 GitHub )。使用示例:

private static int run = 0;

...

[Test]
[Retry(Times = 3, RequiredPassCount = 2)]
public void One_Failure_On_Three_Should_Pass()
{
    run++;

    if (run == 1)
    {
        Assert.Fail();
    }

    Assert.Pass();
}
