For many tests, the dump is not stable or useful to test. Those tests don't have a .nft file in the dumps directory, and don't have it checked. DUMPGEN=y generates a new dump file, if the "dumps/" directory exists. Omitting that directory is a way to prevent the generation of the file. However, many such tests share their directory with tests that do have dumps. When running tests with DUMPGEN=y, a lot of new files get generated. Those files are not meant to be compared or committed to git. Whether a test has a dump file, is part of the test. The absence of the dump file should also be indicated and committed to git. Add a way to opt-out from such generating such dumps by having .nodump files instead of the .nft dump. Later we should add unit tests that checks that no test has both a .nft and a .nodump file in git, that the .nodump file is always empty, and that every .nft/.nodump file has a corresponding test committed to git.
