+# File to S3 Reliability Test
+
+This is a long-running test of Vector tailing a file and sending the data to S3.
+It uses the [`verifiable-logger`][0] project both to generate the log data and
+verify that it all reaches S3.
+
+## Try it
+
+You can run this test via:
+
+```
+test -t file_to_s3_reliability
+```
