SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Verifying that changes to the Erigon Ethereum client do not break anything requires running the full test suite, which takes ~30 minutes and needs specific environment setup (RAM disk, GOGC tuning, rebuilt evm binaries) that is easy to get wrong.

Core Features & Use Cases

  • Full test execution: Runs GOGC=80 make test-all with a 60-minute timeout, equivalent to the "All tests" CI workflow (test-all-erigon.yml).
  • Environment setup guidance: Creates a cross-platform RAM disk via tools/create-ramdisk and exports ERIGON_EXECUTION_TESTS_TMPDIR to match CI conditions.
  • Failure drill-down: Shows how to re-run only the failing package or test with go test -run, and how to map failure output to local package paths.
  • Use Case: Before marking a PR ready for review, run the full gate — RAM disk creation, lint, build, and make test-all — to catch regressions locally instead of waiting for CI.

Quick Start

Ask the assistant to run the full Erigon test suite locally before marking my PR ready for review.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run the full Erigon test suite locally?▼

Create a RAM disk with `path=$(bash tools/create-ramdisk)`, then run `ERIGON_EXECUTION_TESTS_TMPDIR=$path GOGC=80 make test-all`. This matches the All tests CI workflow and takes about 30 minutes with a 60-minute timeout.

How do I re-run only a failing Go test in Erigon?▼

Use `go test --timeout 60m -run TestName ./path/to/package/...` to re-run a specific test, or target the whole failing package with `go test --timeout 60m ./execution/stagedsync/...`. Add `-v` for verbose output and `GOGC=80` to match CI memory pressure.

Why does make test-all need a RAM disk in Erigon?▼

The execution/tests suite performs heavy temp-file I/O, so backing it with tmpfs avoids disk bottlenecks and matches CI, which sets `ramdisk: true` in test-all-erigon.yml. The tools/create-ramdisk script works on Linux, macOS, and Windows.

Why do EEST spec tests fail with a stale evm binary?▼

Calling tools/run-eest-spec-test.sh directly bypasses the Makefile's rebuild of the evm or evm.race binary, so it silently tests whatever binary is on disk. Always invoke shards via `make eest-spec-<shard>` or rebuild with `make evm evm.race` after pulling code.

When should I run make test-all instead of make test-short?▼

Run make test-all before marking a PR ready for review or after significant logic changes. Tests skipped via `-short` run fully here, so failures that pass in test-short usually involve slow paths, large datasets, or DB-heavy operations.
