-/**
- * @fileoverview Provides wrappers around the following global functions from
- * [Mocha's BDD interface](https://github.com/mochajs/mocha):
- *
- * - after
- * - afterEach
- * - before
- * - beforeEach
- * - it
- * - it.only
- * - it.skip
- * - xit
- *
- * Each of the wrapped functions support generator functions. If the generator
- * {@linkplain ../lib/promise.consume yields a promise}, the test will wait
- * for that promise to resolve before invoking the next iteration of the
- * generator:
- *
- * test.it('generators', function*() {
- * let x = yield Promise.resolve(1);
- * assert.equal(x, 1);
- * });
- *
- * The provided wrappers leverage the {@link webdriver.promise.ControlFlow}
- * to simplify writing asynchronous tests:
- *
- * var {Builder, By, until} = require('selenium-webdriver');
- * var test = require('selenium-webdriver/testing');
- *
- * test.describe('Google Search', function() {
- * var driver;
- *
- * test.before(function() {
- * driver = new Builder().forBrowser('firefox').build();
- * });
- *
- * test.after(function() {
- * driver.quit();
- * });
- *
- * test.it('should append query to title', function() {
- * driver.get('http://www.google.com/ncr');
- * driver.findElement(By.name('q')).sendKeys('webdriver');
- * driver.findElement(By.name('btnG')).click();
- * driver.wait(until.titleIs('webdriver - Google Search'), 1000);
- * });
- * });
- *
- * You may conditionally suppress a test function using the exported
- * "ignore" function. If the provided predicate returns true, the attached
- * test case will be skipped:
- *
- * test.ignore(maybe()).it('is flaky', function() {
- * if (Math.random() < 0.5) throw Error();
- * });
- *
- * function maybe() { return Math.random() < 0.5; }
