Patch Changes

#9092 6edd600 Thanks @ematipico! - Fixed #9052. This PR reverts changes introduced by https://github.com/biomejs/biome/pull/8519, which caused unwanted changes on how paths are resolved.
#9091 3bf674d Thanks @ematipico! - Fixed #9090, where SCSS files were incorrectly processed by Biome. This was a regressions caused by the latest developments for supporting SCSS out of the box.
#9100 66931a8 Thanks @siketyan! - Fixed #9081: The noUnknownPseudoElement rule no longer reports false positives for any known pseudo elements in CSS modules. This was a regression introduced in v2.4.0.
#9102 d01b903 Thanks @ematipico! - Fixed #9095, where Biome didn’t print anything in stdin mode. This was a regression caused by a recent, internal refactor.

2.4.2 Latest

Patch Changes

#9103 fc9850c Thanks @dyc3! - Fixed #9098: useImportType no longer incorrectly flags imports used in Svelte control flow blocks ({#if}, {#each}, {#await}, {#key}) as type-only imports.
#9106 f4b7296 Thanks @dyc3! - Updated rule source metadata for rules from html-eslint.

#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noConditionalExpect. This rule disallows conditional expect() calls inside tests, which can lead to tests that silently pass when assertions never run.

1
// Invalid - conditional expect may not run
2
test("conditional", async ({ page }) => {
3
  if (someCondition) {
4
    await expect(page).toHaveTitle("Title");
5
  }
6
});
7

8
// Valid - unconditional expect
9
test("unconditional", async ({ page }) => {
10
  await expect(page).toHaveTitle("Title");
11
});

#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noPlaywrightElementHandle. Prefers locators to element handles.

```

#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noPlaywrightUselessAwait. Disallows unnecessary await on synchronous Playwright methods.

```
#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noPlaywrightWaitForNavigation. Prefers modern navigation APIs over deprecated waitForNavigation().

#9101 0c0fb6f Thanks @siketyan! - Fixed #9080: The noUnusedVariables rule no longer reports a top-level Props interface or type alias as unused in Astro files.

#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule useExpect. This rule ensures that test functions contain at least one expect() assertion.

4
});
5
