    Indicates whether the test described by the given TestData includes the tag org.scalatest.tags.Retryable.

    Indicates whether the test described by the given TestData includes the tag org.scalatest.tags.Retryable.

    This method provides an easy way to selectively retry just tests that are flickering. You can annotated such problematic tests with Retryable, and just retry those. Here's what it might look like:

    override def withFixture(test: NoArgTest) = {
      if (isRetryable(test))
        withRetry { super.withFixture(test) }
      else
        super.withFixture(test)
    }

    Retries the given block with a given delay if the Outcome of executing the block is either Failed or Canceled.

    Retries the given block with a given delay if the Outcome of executing the block is either Failed or Canceled.

    The behavior of this method is defined in the table below. The first two rows show the main "retry" behavior: if executing the block initially fails, and on retry it succeeds, the result is Canceled. The purpose of this is to deal with "flickering" tests by downgrading a failure that succeeds on retry to a cancelation. Or, if executing the block initially results in Canceled, and on retry it succeeds, the result is Succeeded. The purpose of this is to deal with tests that intermittently cancel by ignoring a cancelation that succeeds on retry.

    In the table below, if the “Retry Outcome” has just a dash, the block is not retried. Otherwise, the block is retried on the same thread, after sleeping the given delay.

    First OutcomeRetry OutcomeResult
    Failed Succeeded Canceled (the Succeeded and Failed are discarded; the exception from the Failed is the cause of the exception in the Canceled)

    Canceled Canceled the first Canceled (the second Canceled is discarded)
    Canceled Pending the Canceled (the Pending is discarded)

    the amount of time to sleep before retrying
