foundry-rs/forge-std v1.8.0

on GitHub

Featured Changes

• feat/perf: use native assertions by @klkvr in #514.
  • This replaces forge-std Solidity code with native cheatcode assertions from Foundry, so should give a small performance boost.
  • Assertion failures now cause tests to exit early, instead of continuing with execution.
  • This also will require some visibility modifier changes to tests, as assertion methods no longer set state.
  • NOTE: If you were using the vm.expectSafeMemory cheat, you may need to now use the new vm.stopExpectSafeMemory cheat from #507. See #503 (comment) to learn more, h/t @clabby.
• feat(stdStorage): support packed variables by @klkvr in #505. This means deal now works with USDC and other variables that reply on packed storage slots.
  • The USDC deal support works out of the box.
  • To avoid breaking changes arbitrary packed slot support is not enabled by default, and can be enabled with stdstore.enable_packed_slots().target(.....
• feat: add TOML reading/writing cheatcodes by @zerosnacks in #518. These are analogous to their JSON equivalents.
  • NOTE: This adds file specific keyExistsJson and keyExistsToml cheats. The ambiguous keyExists currently is an alias for keyExistsJson and will be deprecated.
• feat: native string maniupulation cheatcodes of toLowercase, toUppercase, trim, replace and split from foundry-rs/foundry#6891.
• feat: implement interfaces in mock tokens by @arr00 in #510.
