Contradicting tests `invalid/no-seconds.toml` and `valid/no-seconds.toml` about toml-test HOT 6 CLOSED

Yeah, what @eksortso said.

Some tests only apply to specific versions; there's a list in https://github.com/BurntSushi/toml-test/blob/master/version.go

By default only the 1.0 tests are run with toml-test; you need to use toml-test -toml next to select the newer version. If you don't use the toml-test binary you'll need to duplicate that.

Maybe the filenames should be updated to make this more obvious as this confusion has come up before and it will only become more confusing as TOML 1.1, 1.2, etc. get released in the future.

I don't know what the plans will be for the invalid tests in the future, but one way or another, they'll be gone.

The general idea is to remain compatible with all TOML versions whenever possible, since many libraries tend to be fairly slow in updating. In hindsight I should have done this when I updated this from 0.4 to 1.0 since it caused me some pain. Live and learn.

Times without seconds were invalid in TOML v1.0.0. But they are now valid, as of PR 894 of toml-lang/toml, so they will be valid when the first RC of TOML v1.1.0 is released. I don't know what the plans will be for the invalid tests in the future, but one way or another, they'll be gone.

The issue is that I would prefer the filenames to remain stable, so people can skip them and safely update toml-test without worrying about which tests moved around. In the own TOML parser I maintain I skip some minor things because they're fairly hard to fix and, IMHO, not worth the bother.

On the other hand, by adding new TOML 1.1 tests also means people can't safely update, since TOML 1.0 parsers will break.

I'm not 100% sure yet how to best handle this; I will reopen this issue as a reminder that something needs to be done.

Adding the version in the filenames would be great. I am integrating the test files directly into the unit test for the parser (will be published soon), as I try to have as little dependencies possible.

What about adding a version.json file that contains the arrays with included/excluded files?
It would allow to update the test files without altering the test application.

Yeah, that's probably the best solution.

I added a new -list-files flag which will list all the test files for the given -toml flag; it's just one-file-per-line rather than JSON, which is a bit easier to use if you want to copy all the files from the CLI and such.

To make things easier for other people I also added a pre-generated tests/files-toml-1.0.0 and tests/files-toml-1.1.0 which contains the output of that so people don't need to run toml-test themselves.
