## Description
|
|||
|
|
<section id="description">提醒一下，这个项目是基于<a href="https://glitch.com/#!/import/github/freeCodeCamp/boilerplate-mochachai/">Glitch</a>的以下入门项目构建的，或者是从<a href="https://github.com/freeCodeCamp/boilerplate-mochachai/">GitHub</a>克隆的。使用assert.isTrue（）或assert.isNotTrue（）来使测试通过。 .isTrue（true）和.isNotTrue（其他所有内容）都将通过。 .isFalse（）和.isNotFalse（）也存在。 </section>
