Testing Scarb Workspaces

snforge supports Scarb Workspaces. To make sure you know how workspaces work, check Scarb documentation here.

Workspaces With Root Package

When running snforge test in a Scarb workspace with a root package, it will only run tests inside the root package.

For a project structure like this

$ tree . -L 3
Output: 
.
├── Scarb.toml
├── crates
│   ├── addition
│   │   ├── Scarb.toml
│   │   ├── src
│   │   └── tests
│   └── fibonacci
│       ├── Scarb.toml
│       └── src
├── tests
│   └── test.cairo
└── src
    └── lib.cairo

only the tests in ./src and ./tests folders will be executed.

$ snforge test

Failures:

To select the specific package to test, pass a --package package_name (or -p package_name for short) flag. You can also run snforge test from the package directory to achieve the same effect.

$ snforge test --package addition
Output: 
Collected 5 test(s) from addition package
Running 4 test(s) from tests/
[PASS] addition_integrationtest::nested::test_nested::test_two (gas: ~1)
[PASS] addition_integrationtest::nested::test_nested::test_two_and_two (gas: ~1)
[PASS] addition_integrationtest::nested::simple_case (gas: ~1)

Running 1 test(s) from src/
[PASS] addition::tests::it_works (gas: ~1)
Tests: 5 passed, 0 failed, 0 skipped, 0 ignored, 0 filtered out

You can also pass --workspace flag to run tests for all packages in the workspace.

$ snforge test --workspace
Output: 
Collected 5 test(s) from addition package
Running 4 test(s) from tests/
[PASS] addition_integrationtest::nested::test_nested::test_two (gas: ~1)

--package and --workspace flags are mutually exclusive, adding both of them to a snforge test command will result in an error.

Virtual Workspaces

Running snforge test command in a virtual workspace (a workspace without a root package) outside any package will by default run tests for all the packages. It is equivalent to running snforge test with the --workspace flag.

To select a specific package to test, you can use the --package flag the same way as in regular workspaces or run snforge test from the package directory.
