LibXMTP is a shared library encapsulating the core functionality of the XMTP messaging protocol, such as cryptography, networking, and language bindings.
Start Docker Desktop.
-
To install other dependencies and start background services:
dev/upSpecifically, this command creates and runs an XMTP node in Docker Desktop.
-
To run tests:
RUST_LOG=off cargo testMany team members also install and use
cargo nextestfor better test isolation and log output behavior. -
To run WebAssembly tests headless:
dev/test/wasm -
To run WebAssembly tests interactively for a package, for example,
xmtp_mls:dev/test/wasm-interactive xmtp_mls -
To run browser SDK tests:
dev/test/browser-sdk
- Output test logs in a async-aware context-specific tree format with the
environment variable
CONTEXTUAL
CONTEXTUAL=1 cargo test
- Filter tests logs by Crate
RUST_LOG=xmtp_mls=debug,xmtp_api=off,xmtp_id=info cargo test
- Output test logs as in a structured JSON format for inspection with third-party viewer
STRUCTURED=1 cargo test
- Two ways to replace InboxIds/InstallationIds/EthAddresses with a human-readable string name in logs
NOTE: Only works when using CONTEXTUAL=1 flag. So to get the replacement,
CONTEXTUAL=1 cargo test
1.)
Before the test runs, add an TestLogReplace declaration to the top
replace.add accepts two arguments: the string to replace in logs and the
string to replace it with. Note that on dropping the "TestLogReplace" object,
the replacements will no longer be made.
let mut replace = TestLogReplace::default();
replace.add(alix.installation_id(), "alix_installation_id");2.) Build the TesterBuilder with_name
let tester = Tester::builder().with_name("alix").build().await;This replaces all instances of alix's InboxIds, InstallationIds and Identifiers with "alix", "alix_installation", "alix_identifier" respectively, in test output logs.
