All testing is done with make test. Do not use pytest directly. When
possible, testing should be targeted to areas affected by the change rather than
running the full suite. When fixing issues, the targeted set should be run once
to collect failures, then individual failing tests should be re-run to verify
fixes rather than re-running the whole filtered set after each edit.
Tests can be filtered by name via the k=<string> flag. This value is passed
directly to pytest with -k and therefore supports its features, such as
boolean operators (and, or, not). For example,
make test k="gossip and valid" is valid.
Tests can be limited to a single fork via the fork=<fork> flag. It is not
currently possible to specify multiple forks with the flag. The available forks
are the names of all directories in ./specs/ (except for _features) and all
directories in ./specs/_features/.
Tests can be run against a preset via the preset=<preset> flag. There are
three presets: general, minimal, and mainnet. By default, make test only runs
minimal tests. The general tests cover things like BLS, KZG, and SSZ tests. The
minimal tests are fast to execute but do not cover the full range of possible
situations. The mainnet tests are very slow and should only be run in targeted
commands. Note that there are some tests which are only executed under a single
preset.
Tests can be scoped to a component via the component=<comp> flag. Three values
are accepted: all (the default), pyspec, and fw (short for framework). The
pyspec value runs only the spec tests under ./tests/core/pyspec, while fw
runs only the tests under ./tests/infra. Some flags (fork, preset, etc)
are ignored with component=fw since those tests do not depend on the spec.
Reference tests can be generated for clients to ensure compliance with the
specifications. Enable reference tests outputs with the reftests=true flag.
These are written to ./reftests at the project root; this directory is
automatically created. Unlike make test, reftests=true runs all presets
(general, minimal, mainnet) by default; this can be overridden by using the
preset=<preset> flag. The framework deletes individual test case directories
before regenerating them, so targeted reruns will update existing reference
tests. If a test case function was deleted, make test reftests=true will not
delete its previously generated reference test.
Code coverage tracking can be enabled with the coverage=true flag. The results
are available as HTML for humans at ./tests/core/pyspec/.htmlcov/index.html
and as JSON for robots at ./tests/core/pyspec/.htmlcov/coverage.json.
