before/after介绍
<h1>1. 说明</h1>
<h2>1.1 before/after的使用域</h2>
<p>当有before/beforeeach/after/aftereach，以及嵌套的，那么其作用域与普通的语言编程的作用域是一样的道理，只在相应的范围内生效。参考ref1</p>
<pre><code class="language-javascript">before(() => {
// root-level hook
// runs once before all tests
})
beforeEach(() => {
// root-level hook
// runs before every test block
})
afterEach(() => {
// runs after each test block
})
after(() => {
// runs once all tests are done
})
describe('Hooks', () => {
before(() => {
// runs once before all tests in the block
})
beforeEach(() => {
// runs before each test in the block
})
afterEach(() => {
// runs after each test in the block
})
after(() => {
// runs once after all tests in the block
})
})</code></pre>
<h2>1.2 日志中未发现afterall的执行</h2>
<p>根据reference文章中的说明，after的执行并不会单独显示，也不一定是在最后一个用例执行之后执行并在日志中显示，而且在恰当的位置。原句：after is actually executing in the right place, it is just not displaying with the right test. It's just a visual issue.</p>
