# xcm-pez-emulator
|
|
|
|
XCM-Emulator is a tool to emulate XCM program execution using
|
|
pre-configured runtimes, including those used to run on live
|
|
networks, such as Kusama, PezkuwiChain, Asset Hubs, et cetera.
|
|
This allows for testing cross-chain message passing and verifying
|
|
outcomes, weights, and side-effects. It is faster than spinning up
|
|
a zombienet and as all the chains are in one process debugging using Clion is easy.
|
|
|
|
## Limitations
|
|
|
|
As the messages do not physically go through the same messaging infrastructure
|
|
there is some code that is not being tested compared to using slower E2E tests.
|
|
In future it may be possible to run these XCM emulated tests as E2E tests (without changes).
|
|
|
|
As well as the XCM message transport being mocked out, so too are areas around consensus,
|
|
in particular things like disputes, staking and iamonline events can't be tested.
|
|
|
|
## Alternatives
|
|
|
|
If you just wish to test execution of various XCM instructions
|
|
against the XCM VM then the `xcm-pez-simulator` (in the PezkuwiChain
|
|
repo) is the perfect tool for this.
