What I did

I added a new feature to the newly published vitest-test plugin:

Now the test description will use the explictly settled name of the story, and then fallback to the exportName.

The requirement comes from that developers might want to have spaces/brackets/etc... in the test description, which is not allowed in exportName.

At the same time, this can also keep consistent with the name display in storybook preview.

Greptile Summary

This PR enhances the Vitest plugin for Storybook by allowing customizable test descriptions using the story's 'name' property, improving readability and consistency with the Storybook preview.

  • Added new test case in code/core/src/csf-tools/vitest-plugin/transformer.test.ts to verify the 'name' property usage
  • Updated docs/writing-tests/vitest-plugin.mdx with instructions on customizing test descriptions using the 'name' property
  • This change allows for more descriptive test names, including spaces and special characters not permitted in export names
