<h2><a class="anchor" name="-"></a>얕은 렌더링 <a class="hash-link" href="#-">#</a></h2>
|
|
<p>얕은 렌더링은 "한 단계 깊이의" 컴포넌트를 렌더할 수 있는 실험적인 기능입니다. 자식 컴포넌트가 인스턴스화 되거나 렌더되는 등의 동작에 대한 걱정 없이 렌더 메소드가 반환하는 것만 검증합니다. 이 기능은 DOM이 필요하지 않습니다.</p>
|
|
<div class="highlight"><pre><code class="language-javascript" data-lang="javascript"><span class="nx">ReactShallowRenderer</span> <span class="nx">createRenderer</span><span class="p">()</span>
|
|
</code></pre></div>
|
|
<p>테스트에서 얕은 렌더러를 생성하고자 할때 호출합니다. 이를 이벤트와 업데이트에 스스로 반응하는 컴포넌트를 렌더하기 위한 "장소"라고 생각할 수 있습니다.</p>
|
|
<div class="highlight"><pre><code class="language-javascript" data-lang="javascript"><span class="nx">shallowRenderer</span><span class="p">.</span><span class="nx">render</span><span class="p">(</span>
|
|
<span class="nx">ReactElement</span> <span class="nx">element</span>
|
|
<span class="p">)</span>
|
|
</code></pre></div>
|
|
<p><code>ReactDOM.render</code>와 유사합니다.</p>
|
|
<div class="highlight"><pre><code class="language-javascript" data-lang="javascript"><span class="nx">ReactElement</span> <span class="nx">shallowRenderer</span><span class="p">.</span><span class="nx">getRenderOutput</span><span class="p">()</span>
|
|
</code></pre></div>
|
|
<p><code>render</code>가 호출 된 후, 얕게 렌더된 결과물을 반환합니다. 그 후엔 결과물에 대한 검증을 시작할 수 있습니다. 예를 들어 컴포넌트의 렌더 메소드가 다음을 반환한다면:</p>
|
|
<div class="highlight"><pre><code class="language-javascript" data-lang="javascript"><span class="o"><</span><span class="nx">div</span><span class="o">></span>
|
|
<span class="o"><</span><span class="nx">span</span> <span class="nx">className</span><span class="o">=</span><span class="s2">"heading"</span><span class="o">></span><span class="nx">Title</span><span class="o"><</span><span class="err">/span></span>
|
|
<span class="o"><</span><span class="nx">Subcomponent</span> <span class="nx">foo</span><span class="o">=</span><span class="s2">"bar"</span> <span class="o">/></span>
|
|
<span class="o"><</span><span class="err">/div></span>
|
|
</code></pre></div>
|
|
<p>그 후에는 검증할 수 있습니다:</p>
|
|
<div class="highlight"><pre><code class="language-javascript" data-lang="javascript"><span class="nx">result</span> <span class="o">=</span> <span class="nx">renderer</span><span class="p">.</span><span class="nx">getRenderOutput</span><span class="p">();</span>
|
|
<span class="nx">expect</span><span class="p">(</span><span class="nx">result</span><span class="p">.</span><span class="nx">type</span><span class="p">).</span><span class="nx">toBe</span><span class="p">(</span><span class="s1">'div'</span><span class="p">);</span>
|
|
<span class="nx">expect</span><span class="p">(</span><span class="nx">result</span><span class="p">.</span><span class="nx">props</span><span class="p">.</span><span class="nx">children</span><span class="p">).</span><span class="nx">toEqual</span><span class="p">([</span>
|
|
<span class="o"><</span><span class="nx">span</span> <span class="nx">className</span><span class="o">=</span><span class="s2">"heading"</span><span class="o">></span><span class="nx">Title</span><span class="o"><</span><span class="err">/span>,</span>
|
|
<span class="o"><</span><span class="nx">Subcomponent</span> <span class="nx">foo</span><span class="o">=</span><span class="s2">"bar"</span> <span class="o">/></span>
|
|
<span class="p">]);</span>
|
|
</code></pre></div>
|
|
<p>현재 얕은 테스트는 refs를 지원하지 않는 등 몇가지 제약사항이 있습니다. 우리는 이 기능을 빠르게 먼저 배포하고 React 커뮤니티의 피드백을 받아 나아갈 방향을 찾고자 합니다.</p>
