Spec-testing

Installing

To run the spec tests, you need the test-vectors provided here: https://github.com/ethereum/eth2.0-spec-tests These vectors are hosted in a Git LFS repository. Alternatively, you can download a .tar.gz from the releases page.

Next, you place the repository in <zrnt root>/tests/spec/eth2.0-spec-tests, or, symlink to them (your paths may vary):

ln -s ../../../eth2.0-specs/eth2.0-spec-tests tests/spec/eth2.0-spec-tests

Running

The tests are compatible with the go test tooling, and can be ran per-handler, and are filtered based on build settings.

Order:

  1. Test runner collection Example: go test -tags preset_minimal ./test_runners/...
  2. Test runner: e.g. operations Example: go test -tags preset_minimal ./test_runners/operations
  3. Test handler: e.g. transfer Run: go test -tags preset_minimal ./test_runners/operations -run TestTransfer
  4. Test suite(s) loaded by handler, filtered based on active configuration (same build tags apply to tests) To filter, use the title of the suite (can be incomplete / match multiple). Example: go test -tags preset_minimal ./test_runners/operations -run 'TestTransfer/transfer operation
  5. Test cases, executed by handler To filter, use the title provided by the test. or the number (if the handler does not provide titling). Examples:
    • go test -tags preset_minimal ./test_runners/operations -run 'TestTransfer/transfer operation/success_withdrawable'
    • go test -tags preset_minimal ./test_runners/ssz_static -run 'TestSSZStatic/chaos/case #3'
  6. Test case conditions A test fails/pass, withs stacktrace etc. Go test tooling docs here: cmd and testing pkg
