Retry

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

[!code-csharpRetry]

Notes:

1. The argument you specify is the total number of attempts and not the number of retries after an initial failure. So [Retry(1)] does nothing and should not be used.

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

3. If a test has an unexpected exception, an error result is returned and it is not retried.

   From NUnit 4.5.0 you can enable retry on an expected exception such as TimeoutException by setting the RetryExceptions property. The value of this property is an array of anticipated exceptions that should be retried.
