我几乎没有网站UI自动化的测试用例。
如果第一次和第二次失败，我想尝试至少三次我的测试用例。这样，我想确保此测试用例始终失败。
如果我们在NUnit中有任何选择，请告诉我。我正在使用C＃和NUnit。
您可以根据属性repeat在nunit中添加新属性并重建库。这很简单。
[Test]
[Repeat( 25 )]
public void MyTest( ){
// your test logic here
}
从NUnit 3.0开始，有一个“重试”属性，看起来它将完全符合kumar的要求。
对于逻辑循环，计数失败。断言。（失败== 0）轰隆完成。
我建议你不要这样做。写一个更好的测试，你可以证明是一致的。
nunit使用4个例外来告诉测试结果。它们是：TimeoutException，AssertException，SuccessException和IgnoreException。您可以在nunit测试函数中使用这些。我猜你可以把你的测试代码放在try-catch中，然后捕获nunit断言异常两次。但我应该说，正如之前评论的那样，需要间歇性地失败的测试是重新思考的一个原因。
如果希望测试用例在报告失败之前多次运行，则可以使用“重试属性”。
[Test]
[Retry(3)]
public void MyTest( ){
// your test logic here
}
我在python中为nunit3-console创建了一个包装器脚本，它运行脚本，如果有任何失败的测试，将重新运行失败的测试，最多可达--max-retries次。它还将新结果合并到原始的TestResult.xml中。
该脚本名为nunit-repeat，位于https://github.com/sashoalm/nunit-repeat/。
用法示例：
python nunit-repeat.py --max-retries 3 -- .\MockFailingTests\packages\NUnit.ConsoleRunner.3.10.0\tools\nunit3-console.exe .\MockFailingTests\MockFailingTests\bin\Debug\MockFailingTests.dll
