dilipbiswal opened a new pull request #23995: [SQL][MINOR][TEST] Include usage example for generating output for single test in SQLQueryTestSuite URL: https://github.com/apache/spark/pull/23995 ## What changes were proposed in this pull request? This is a very minor pr to include the usage example to generate output for single test in SQLQueryTestSuite. I tried to deduce it from the existing example and ran into a scenario where sbt is simply looping to run the same test over and over again. Here is the example of running a single test. ``` build/sbt "~sql/test-only *SQLQueryTestSuite -- -z inline-table.sql" ``` I tried to generate the output for a single test by prepending `SPARK_GENERATE_GOLDEN_FILES=1` like following ``` SPARK_GENERATE_GOLDEN_FILES=1 build/sbt "~sql/test-only *SQLQueryTestSuite -- -z describe.sql" ``` In this case i found that sbt is looping trying to run describe.sql over and over again as we are running the test in on continuous mode (because of `~` prefix ) where it detects a change in the generated result file which in turn triggers a build and test. I have included an example where we don't run it in continuous when generating the output. Hopefully it saves other developers some time. ## How was this patch tested? Verified manually in my dev setup.
