Formerly known as ibctest.
interchaintest orchestrates Go tests that utilize Docker containers for multiple
IBC-compatible blockchains.
It allows users to quickly spin up custom testnets and dev environments to test IBC, chain infrastructures, smart contracts, etc.
- Branch Versioning
- Use Cases:
- Importing as a Module
- Running as a Binary
- Building Binary
- Running Conformance Tests - Suite of built-in tests that test high-level IBC compatibility
- Write Custom Tests
- Environment Variable Options
- Retaining Data on Failed Tests
| Branch Name | IBC-Go | Cosmos-sdk |
|---|---|---|
| main | v8 | v0.50 |
| v7 | v7 | v0.47 |
These are branches that we no longer actively update or maintain but may be of use if a chain is running older versions of the Cosmos SDK or IBC Go. Please see the Backport Policy below.

Strangelove maintains n and n - 1 branches of interchaintest, n being current main.
We strive to keep interchaintest inline with the latest from the ibc-go and cosmos sdk teams. Once an alpha versions of the next major ibc-go version is released, we will discontinue n - 1 and branch off a new n.
Recommendation: Even if your chain uses an older version of ibc-go, try importing from main. This should work unless you are decoding transactions that require a specific ibc-go version.
If there is a feature you would like backported to an older branch, make an issue! We are happy to work with you.
