* Patch all substrate deps to use my substrate branch * default-features = false causing issus in test-runtime * Use substrate polkadot release branch * Use default-features for sp-runtime again :( * Restore default-features for subxt-cli/sp-core * Fix module error integration test * Add Send + Sync bounds to ExtrinsicEvents::iter() * Elide lifetime * Revert adding Send + Sync * Add Sync bound to Rpc::ClientError * Remove version in subxt-metadata * Use released crates * Use released sp-keyring * Fix sp-keyring deps * Remove unnecessary sp-keyring default-features = false
test-runtime
The logic for this crate exists mainly in the build.rs file.
At compile time, this crate will:
- Spin up a local
substratebinary (set theSUBSTRATE_NODE_PATHenv var to point to a custom binary, otherwise it'll look forsubstrateon your PATH). - Obtain metadata from this node.
- Export the metadata and a
node_runtimemodule which has been annotated using thesubxtproc macro and is based off the above metadata.
The reason for doing this is that our integration tests (which also spin up a Substrate node) can then use the generated subxt types from the exact node being tested against, so that we don't have to worry about metadata getting out of sync with the binary under test.
