Legacy IBC Testing

legacy_ibc_testing is imported from Informal Systems fork of ibc-go. It contains modifications to canonical ibc-go v3.4.0 for testing purposes only.

Crucially, Informal's fork contained changes to the StakingKeeper interface that both consumer and providers would be expected to return from the testing method GetStakingKeeper. For consumer apps, this method would return and IBCKeeper type. This change could not be back-ported to v3.4.0 of ibc-go as it would be api breaking. Instead, the relevant changes made to ibc-go were consolidated and copied directly into interchain-security. Once ICS upgrades ibc-go to a version that supports this change, v5 at the earliest, this test helper directory can be removed.

Directory

• Core
  • Contains changes made in ibc-go core/, but do not contain any logic requiring they live in that directory. Includes an interface definition and a testing helper method.
• Simapp
  • Includes test helper substitutions for ibc-go's simapp/ used in the Diff tests.
• Testing
  • Replaces ibc-go's testing/ directory to facilitate ibc's TestApp's implementation of GetStakingKeeper returning the relevant StakingKeeper interface enhanced in Informal's ibc-go fork.
