context.runOnly(shouldRunOnlyTests)

• shouldRunOnlyTests <boolean> 是否运行 only 测试。

  ¥shouldRunOnlyTests <boolean> Whether or not to run only tests.

如果 shouldRunOnlyTests 为真，则测试上下文将只运行设置了 only 选项的测试。否则，将运行所有测试。如果 Node.js 不是使用 --test-only 命令行选项启动的，则此函数是无操作的。

¥If shouldRunOnlyTests is truthy, the test context will only run tests that have the only option set. Otherwise, all tests are run. If Node.js was not started with the --test-only command-line option, this function is a no-op.

test('top level test', (t) => {
  // The test context can be set to run subtests with the 'only' option.
  t.runOnly(true);
  return Promise.all([
    t.test('this subtest is now skipped'),
    t.test('this subtest is run', { only: true }),
  ]);
}); 拷贝
