On the README doc I miss the types for the event details, so I'm assuming:

• Test: object - A test holds basic information on a single test/spec.
  • testName: string - name of the test
  • suiteName: string - name of the suite the test belongs to
  • status: string - result of the test. Can "passed", "failed" or "skipped". A skipped test is disabled, i.e. it will not be executed.
  • runtime: number - execution time in milliseconds
  • errors: array of string only | string - Depending on the framework, this is a single exception or a list of failed assertions. Will be an empty array for statuses other than failed.
• Suite: A suite is a collection of tests and potentially other suites.
  • name: string - name of the suite
  • childSuites: array - array with all direct subsuites (objects or string names?)
  • tests: array - array containing all tests that directly belong to the suite (but not to a child suite)
  • runtime: number - execution time of the whole suite in milliseconds (including child suites)
  • status: object - summarized status of the suite (should it appear on suiteStart?)
    • failed, number - if at least one test failed how many tests failed? from 0 to n?
    • skipped: number: if all tests in the suite are skipped (and there is at least one skipped test) how many skipped tests? from 0 to n?
    • passed: number if there is at least one passed test and all other tests are skipped or if there are no tests in the suite. how many passed tests? from 0 to n?

Should we have an status total as well?
