<h3><a name="t0"></a><strong>1. 什麼是mock數據？</strong></h3>
<p>mock測試是指在測試過程中，對於某些不容易構成或者不容易獲取的對象，用一個虛擬的對象來創建一邊測試的測試方法。（來自百度百科）</p>
<p>系統開發中的mock數據就是指前端開發人員模擬後端接口，自行獲取需要的數據。（自給自足）</p>
<h3><a name="t1"></a><strong>2. 爲什麼要使用mock數據？</strong></h3>
<p>使用mock數據可以在後端開發人員尚未完成接口編寫的情況下實現js完整邏輯的編寫，與nodeJs的特性類似，我們可以將其稱之爲異步編程。</p>
<p>沒有使用mock數據的workflow如下：</p>

<h3><a name="t2"></a><strong>3. 怎麼使用mock數據？</strong></h3>
<p><strong>3.1 安裝nodeJs</strong></p>
<p>不多講，網上都可以找到教程 http://www.runoob.com/nodejs/nodejs-install-setup.html</p>
<p><strong>3.2 創建nodeJs項目</strong></p>
<pre class="has" name="code"><code class="language-bash hljs"><ol class="hljs-ln"><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="1"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">mkdir nodeMock // 創建文件夾</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="2"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line"><span class="hljs-built_in">cd</span> nodeMock </div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="3"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">npm init -y // 初始化一個nodeJs項目，創建一個默認的package.json文件</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="4"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">npm install // 安裝node_modulses</div></div></li></ol></code><div class="hljs-button {2}" data-title="複製" οnclick="hljs.copyCode(event)"></div></pre>
<p><strong>3.3 撰寫mock數據</strong></p>
<p>在項目根目錄創建一個單獨的json文件，放置需要的數據，格式如下：</p>
