-- The TestRole operation tests the IAM role used to create the pipeline.
--
-- The 'TestRole' action lets you determine whether the IAM role you are
-- using has sufficient permissions to let Elastic Transcoder perform tasks
-- associated with the transcoding process. The action attempts to assume
-- the specified IAM role, checks read access to the input and output
-- buckets, and tries to send a test notification to Amazon SNS topics that
-- you specify.
