The test expects an IOException when creating a writer for file `target/test/data/recursiveCreateDir/file` with `createParent=false`. And it expects to create the writer successfully when `createParent=True`. `createParent` means `create parent directory if non-existent`.
The test will pass if it is run for the first time, but it will fail for the second run. This is because the test did not clean the parent directory created during the first run.
The parent directory `recursiveCreateDir` was created, but it was not deleted before the test finished. So, when the test was run again, it still treated the parent directory `recursiveCreateDir` as non-existent and expected an IOException from creating a writer with `createParent=false`. Then the test did not get the expected IOException because `recursiveCreateDir` has been created in the first test run.
