bun test

[endersonmaia]

This pull request migrates the apps/cli integration and unit tests from Vitest to Bun's native test runner, and updates the test infrastructure to improve reliability and maintainability. It also updates the test Docker image handling to ensure required images are available before running integration tests, and modernizes the coverage reporting in the CI workflow.

Test runner migration and improvements:

• Replaced all usage of Vitest in integration and unit tests with Bun's test runner, updating imports and test APIs accordingly across all test files. (apps/cli/tests/integration/builder/directory.test.ts, apps/cli/tests/integration/builder/docker.test.ts, apps/cli/tests/integration/builder/empty.test.ts, apps/cli/tests/integration/builder/none.test.ts, apps/cli/tests/integration/builder/tar.test.ts, apps/cli/tests/integration/exec/cartesi-machine.test.ts, apps/cli/tests/integration/exec/genext2fs.test.ts, apps/cli/tests/integration/exec/mksquashfs.test.ts, apps/cli/tests/unit/config.test.ts) [1] [2] [3] [4] [5] [6] [7] [8] [9]

• Removed the vitest dependency from package.json and updated the test script to use bun test instead. (apps/cli/package.json) [1] [2]

Test infrastructure and Docker image handling:

• Added a global setup function, setupIntegrationTests, to ensure required Docker images are present before running integration tests, improving test reliability and developer experience. (apps/cli/tests/integration/config.ts)

• Updated all integration tests to call setupIntegrationTests in a beforeAll hook, ensuring Docker images are prepared before any tests run. (apps/cli/tests/integration/builder/directory.test.ts, apps/cli/tests/integration/builder/docker.test.ts, apps/cli/tests/integration/builder/empty.test.ts, apps/cli/tests/integration/builder/none.test.ts, apps/cli/tests/integration/builder/tar.test.ts, apps/cli/tests/integration/exec/cartesi-machine.test.ts, apps/cli/tests/integration/exec/genext2fs.test.ts, apps/cli/tests/integration/exec/mksquashfs.test.ts) [1] [2] [3] [4] [5] [6] [7] [8]

• Updated the test SDK image constant to use values from the main config, ensuring consistency across environments. (apps/cli/tests/integration/config.ts)

Temporary directory management for tests:

• Replaced the custom tmpdirTest Vitest fixture with a new setupTempDir helper for managing temporary directories in Bun tests, and updated all affected tests to use this new approach. (apps/cli/tests/integration/builder/tmpdirTest.ts, and all integration test files) [1] [2] [3] [4] [5] [6]

CI workflow and coverage reporting:

• Updated the GitHub Actions workflow to use Bun's built-in coverage reporter and switched to a Bun-compatible coverage reporting action, removing the Vitest-specific coverage action. (.github/workflows/cli.yaml)
