Justin Traglia 2f807e21be Add support for nightly tests (#7538)
This PR adds the ability to download [nightly reference tests from the consensus-specs repo](https://github.com/ethereum/consensus-specs/actions/workflows/generate_vectors.yml). This will be used by spec maintainers to ensure that there are no unexpected test failures prior to new releases. Also, we will keep track of test compliance with [this website](https://jtraglia.github.io/nyx/); eventually this will be integrated into Hive.


  * A new script (`download_test_vectors.sh`) is added to handle downloads.
* The logic for downloading GitHub artifacts is a bit complex.
* Rename the variables which store test versions:
* `TESTS_TAG` to `CONSENSUS_SPECS_TEST_VERSION`.
* `BLS_TEST_TAG` to `BLS_TEST_VERSION`, for consistency.
* Delete tarballs after extracting them.
* I see no need to keep these; they just use extra disk.
* Consolidate `clean` rules into a single rule.
* Do `clean` prior to downloading/extracting tests.
* Remove `CURL` variable with GitHub token; don't need it for downloading releases.
* Do `mkdir -p` when creating directories.
* Probably more small stuff...

Consensus Specification Tests

This crate parses and executes the test vectors at ethereum/consensus-spec-tests.

Functionality is achieved only via the $ cargo test --features ef_tests command.

Running the Tests

Because the test vectors are very large, we do not download or run them by default. To download them, run (in this directory):

$ make

Note: this may download hundreds of MB of compressed archives from the ethereum/consensus-spec-tests, which may expand into several GB of files.

If successful, you should now have the extracted tests in ./consensus-spec-tests.

Run them with:

$ cargo test --features ef_tests

The tests won't run without the ef_tests feature enabled (this is to ensure that a top-level cargo test --all won't fail on missing files).

The following is sometimes necessary to avoid stack overflow issues when running on MacOS:

$ export RUST_MIN_STACK=8388608

When debugging failing tests, it's often useful to disable parallization and output suppression:

$ cargo test --features ef_tests,disable_rayon -- --nocapture

Saving Space

When you download the tests, the downloaded archives will be kept in addition to the extracted files. You have several options for saving space:

  1. Delete the archives (make clean-archives), and keep the extracted files. Suitable for everyday use, just don't re-run make or it will redownload the archives.
  2. Delete the extracted files (make clean-test-files), and keep the archives. Suitable for CI, or temporarily saving space. If you re-run make it will extract the archives rather than redownloading them.
  3. Delete everything (make clean). Good for updating to a new version, or if you no longer wish to run the EF tests.
