Description

This unit test was leaky because it was stubbing out 'fs' but the code was writing files with 'fs-extra'. This left a extra dataconnect/conector/connector.yaml file floating around after runs.

Scenarios Tested

Ran the tests, and no leftover files/

Summary of Changes

Hello @joehan, 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 addresses a leaky unit test within src/init/features/dataconnect/sdk.spec.ts. The test was incorrectly stubbing the native fs module while the underlying code was using fs-extra for file operations, leading to residual connector.yaml files after test runs. The changes ensure that the test correctly stubs fs-extra, preventing the creation of unwanted files and maintaining a clean test environment.

Highlights

  • Test Fix: Corrected a leaky unit test in src/init/features/dataconnect/sdk.spec.ts that was inadvertently leaving behind connector.yaml files after test execution.
  • Module Stubbing Alignment: Updated the test's stubbing mechanism to correctly target fs-extra (specifically writeFileSync and ensureFileSync) instead of the standard fs module, resolving the issue where file operations were not properly mocked.

Code Review

This pull request correctly fixes a leaky unit test by changing the stubbed module from fs to fs-extra and adding a stub for ensureFileSync. The changes are accurate and address the issue described. I've added one comment suggesting an improvement to the test's assertions to make it more comprehensive.

fsStub = sandbox.stub(fs, "writeFileSync");
sandbox.stub(fs, "ensureFileSync").returns();

Good catch fixing the leaky test by stubbing ensureFileSync. To make this test more robust and fully align with its description ('should write files and generate code'), consider adding assertions to verify that both ensureFileSync and writeFileSync are called during the test execution. This would ensure the file writing part of the actuate function is also tested.
