Summary of Changes

Hello @zhzhuang-zju, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly refactors and enhances the end-to-end testing for the karmadactl init command. The primary goal is to create a more robust and maintainable testing framework by unifying existing tests and introducing a new comprehensive base test. This ensures that the entire Karmada instance lifecycle, from initial setup to basic resource propagation, is thoroughly validated in an automated fashion, improving the reliability of the initialization process.

Highlights

• Unified E2E Test Suite: Consolidated init-related tests from ci.yml and installation-cli.yaml into a single, comprehensive end-to-end test suite for karmadactl init, streamlining the testing process.
• New Base E2E Test: Introduced base_test.go to cover the full lifecycle of a Karmada instance, including installation, member cluster joining, and basic resource propagation, ensuring core functionality is validated.
• Environment Setup Refactoring: Refactored hack/init-e2e-environment.sh to leverage hack/setup-dev-base.sh, simplifying the script and promoting reusability for development environment setup.
• Test Script Updates: Updated hack/run-e2e-init.sh to align with the new unified E2E suite, including changes to environment variable names and the ginkgo command execution.
• Improved Test Isolation: Enhanced test isolation in test/e2e/suites/init by introducing global variables for karmadaDataPath and karmadaAPIServerNodePort, ensuring unique temporary directories and ports for each test run.

Code Review

This pull request refactors the cmdinit E2E test environment to unify it with the CI process. The changes primarily involve simplifying init-e2e-environment.sh by moving common setup logic to setup-dev-base.sh, and updating the Go test files for better structure and clarity. My review focuses on ensuring the refactored scripts work as intended. I've identified a critical issue where a required test file is no longer placed in the correct directory, which would likely break the E2E tests. I've also noted a couple of minor typos in a script's copyright header and in the new README file. Overall, the refactoring is a good improvement, and with the suggested fixes, it should be solid.
