Wasmer Integration tests

All Wasmer end to end integration tests live here. We have different kind of integration tests:

CLI Integration tests

This tests check that the wasmer CLI works as it should when running it as a Command in a shell, for each of the supported compilers.

Snapshot Tests

A snapshot test suite is located at ./cli/tests/snapshot.rs.

The file contains tests that run various Webassembly files through wasmer run. The output is stored as snapshots in the repository.

The insta crate is used for snapshots.

Working With Snapshots

  • Install the cargo-insta CLI cargo install cargo-insta
  • Update snapshots: 
    cd ./cli/
cargo insta test --review -- snapshot

C Integration tests

This tests verify that Wasmer wasm-c-api tests are passing for each of the supported compilers.

Rust Integration tests

This tests verify that the wasmer API fulfill the required API that external users use.
