    "incantation": "When selected tests must be skipped before the run begins, implement `Reporter.preprocess()` and call `testRun.skip(test)` for each matching test in `suite.allTests()`.",
    "examples": [
      "class MyReporter {\n  async preprocess({ config, suite, testRun }) {\n    for (const test of suite.allTests()) {\n      if (shouldSkip(test)) // Replace with your selection condition.\n        testRun.skip(test);\n    }\n  }\n}"

    "gotchas": [
      "Version: v1.62.0",
      "config (required): Resolved configuration passed to `preprocess`.",
      "suite (required): Root suite; `suite.allTests()` returns tests in it and its descendants. It reflects project, grep, and `.only` filtering; setup and dependency projects are read-only.",
      "testRun (required): Controls which tests run and their expected status.",
      "test (required): `TestCase` or `Suite` to skip; test bodies are not executed and tests are reported as skipped.",
      "reason: Optional explanation surfaced as the annotation description by `testRun.skip(test, reason)`.",
      "Prerequisite: Playwright v1.62 or later; `reporter.preprocess()` and `testRun.skip()` were added in v1.62.",
      "The hook runs after configuration is resolved and before `reporter.onBegin()`.",
      "The release says the hook lets reporters mark tests skipped, excluded, fixed, or failing through a `TestRun` object."
