v0.2.5

Tests

Cancun

• Separate fixtures to test for Cancun: includes the first version of the 4844 fixtures. (#63)
• These currently test for valid/invalid blob transactions, excess data gas calculations and the DATAHASH opcode.
• Additional tests for kzg pre-compiles and ssz will be added in a future release.
• Test documentation can be found -> here.
• These will be run within the hive pyspec simulator on this branch.

Important: These tests can only be filled using the geth version listed below, alongside the --latest-fork Cancun flag. As an example, you can run the 4844 tests with the following command: tf --force-refill --latest-fork Cancun --test-categories eips.eip4844.

v0.2.4

Changes

• Additional checks added to the Tox pipeline. Python file and function names now checked in accordance with PEP8. (PR: #59)
• Naming style structure changed in the fixture format. withdrawals_ head removed from name of all withdrawals fixtures. Fixture test case names now like 000/shanghai instead of 000_shanghai. Tags added to specific test case names i.e. 001/multiple_blocks/shanghai. (PR: #69)
• Updates and additions to the test filler tf: (PRs: #66 & #72)
  • Refactor of ethereum_test_filling_tool.
  • Default tf execution is now concurrent/parallel. So far ~65% increase in speed which will scale as more tests are added.
  • Filling is skipped for tests that don't need to be filled by default. Improvement to tf execution speed.
  • tf --benchmark. Adds timing of filling to the console logs.
  • tf --max-workers. Allows the user to set the number of workers used for concurrent tf execution. For serial execution (the previous way) use tf --max-workers 1.
  • tf --force-refill. Force tests to be filled. Works with --test-module and --test-categories.
  • tf --no-output-structure. When enabled all tests are added to a single equivalent output folder.
