From 1a8fcca03fd6ff5acec8ca97fc20766df74f2ccb Mon Sep 17 00:00:00 2001 From: Hanna Reitz Date: Mon, 21 Feb 2022 18:29:09 +0100 Subject: iotests: Write test output to TEST_DIR Drop the use of OUTPUT_DIR (test/qemu-iotests under the build directory), and instead write test output files (.out.bad, .notrun, and .casenotrun) to TEST_DIR. With this, the same test can be run concurrently without the separate instances interfering, because they will need separate TEST_DIRs anyway. Running the same test separately is useful when running the iotests with various format/protocol combinations in parallel, or when you just want to aggressively exercise a single test (e.g. when it fails only sporadically). Putting this output into TEST_DIR means that it will stick around for inspection after the test run is done (though running the same test in the same TEST_DIR will overwrite it, just as it used to be); but given that TEST_DIR is a scratch directory, it should be clear that users can delete all of its content at any point. (And if TEST_DIR is on tmpfs, it will just disappear on shutdown.) Contrarily, alternative approaches that would put these output files into OUTPUT_DIR with some prefix to differentiate between separate test runs might easily lead to cluttering OUTPUT_DIR. (This change means OUTPUT_DIR is no longer written to by the iotests, so we can drop its usage altogether.)
