Description
Run SUnit tests in the running Smalltalk image (Pharo or Squeak). Use when verifying changes after import, or when checking results for a specific test class or package.

Run SUnit Tests

Execute SUnit tests after importing changes to the Smalltalk image.

Usage

/st-test TestClassName       # run a single test class
/st-test PackageName-Tests   # run all tests in a package

Steps

With arguments: run a specific test class or package

  1. Determine whether the argument is a class name or a package name
    • Class name (e.g. RsJsonTest) → call run_class_test
    • Package name (e.g. RediStick-Json-Tests) → call run_package_test
  2. Report pass/fail counts and any failures

Without arguments: run all test packages in the project

When no arguments are given, discover and run all test packages automatically:

  1. Locate the source directory — read .project from the repository root and extract the srcDirectory value. Resolve it to an absolute path.

  2. Identify test packages — find the BaselineOf package inside the source directory (a directory starting with BaselineOf) and read its BaselineOfXXX.class.st. Parse the baseline: spec method and collect all packages whose names end with -Tests (or follow the project's test-naming convention).

  3. Check what is already imported — call list_packages to get the list of packages currently loaded in the Smalltalk image.

  4. Run tests for imported packages — for each test package that is present in the image, call run_package_test and report the pass/fail results.

  5. Report unimported packages — for any test package found in the BaselineOf but not loaded in the image, skip running tests and report it to the user with a note that they can run /st-import first to load it.

Examples

/st-test RsJsonTest
/st-test RediStick-Json-Tests
