<blockquote>
|
|
|
<p>开始之前，推荐大家先了解下<a href="https://course.rs/test/intro.html">如何在 Rust 中编写测试代码</a>，这块儿内容不复杂，先了解下有利于本章的继续阅读</p>
|
|
|
</blockquote>
|
|
|
<p>在之前的章节中，我们完成了对项目结构的重构，并将进入逻辑代码编程的环节，但在此之前，我们需要先编写一些测试代码，也是最近颇为流行的测试驱动开发模式(TDD, Test Driven Development)：</p>
|
|
|
<ol>
|
|
|
<li>编写一个注定失败的测试，并且失败的原因和你指定的一样</li>
|
|
|
<li>编写一个成功的测试</li>
|
|
|
<li>编写你的逻辑代码，直到通过测试</li>
|
|
|
</ol>
|
|
|
<p>这三个步骤将在我们的开发过程中不断循环，直到所有的代码都开发完成并成功通过所有测试。</p>
|
|
|
<h2 id="注定失败的测试用例"><a class="header" href="#注定失败的测试用例">注定失败的测试用例</a></h2>
|
|
|
<p>既然要添加测试，那之前的 <code>println!</code> 语句将没有大的用处，毕竟 <code>println!</code> 存在的目的就是为了让我们看到结果是否正确，而现在测试用例将取而代之。</p>
|
|
|
<p>接下来，在 <code>lib.rs</code> 文件中，添加 <code>tests</code> 模块和 <code>test</code> 函数: </p>
|
|
|
<pre><pre class="playground"><code class="language-rust edition2021"><span class="boring">#![allow(unused)]
|
|
|
</span><span class="boring">fn main() {
|
|
|
</span>#[cfg(test)]
|
|
|
mod tests {
|
|
|
use super::*;
|
|
|
|
|
|
#[test]
|
|
|
fn one_result() {
|
|
|
let query = "duct";
|
|
|
let contents = "\
|
|
|
Rust:
|
|
|
safe, fast, productive.
|
|
|
Pick three.";
|
|
|
|
|
|
assert_eq!(vec!["safe, fast, productive."], search(query, contents));
|
|
|
}
|
|
|
}
|
|
|
<span class="boring">}</span></code></pre></pre>
|
|
|
<p>测试用例将在指定的内容中搜索 <code>duct</code> 字符串，目测可得：其中有一行内容是包含有目标字符串的。</p>
|
|
|
<p>但目前为止，还无法运行该测试用例，更何况还想幸灾乐祸的看其失败，原因是 <code>search</code> 函数还没有实现！毕竟是测试驱动、测试先行。</p>
|
|
|
<pre><pre class="playground"><code class="language-rust edition2021"><span class="boring">#![allow(unused)]
|
|
|
</span><span class="boring">fn main() {
|
|
|
</span>// in lib.rs
|
|
|
pub fn search<'a>(query: &str, contents: &'a str) -> Vec<&'a str> {
|
|
|
vec![]
|
|
|
}
|
|
|
<span class="boring">}</span></code></pre></pre>
|
|
|
<p>先添加一个简单的 <code>search</code> 函数实现，非常简单粗暴的返回一个空的数组，显而易见测试用例将成功通过，真是一个居心叵测的测试用例！</p>
|
|
|
<p>注意这里生命周期 <code>'a</code> 的使用，之前的章节有<a href="https://course.rs/basic/lifetime.html#%E5%87%BD%E6%95%B0%E7%AD%BE%E5%90%8D%E4%B8%AD%E7%9A%84%E7%94%9F%E5%91%BD%E5%91%A8%E6%9C%9F%E6%A0%87%E6%B3%A8">详细介绍</a>，不太明白的同学可以回头看看。</p>
|
|
|
<p>喔，这么复杂的代码，都用上生命周期了！嘚瑟两下试试：</p>

|
<p>太棒了！它失败了...</p>
|
|
|
<h2 id="务必成功的测试用例"><a class="header" href="#务必成功的测试用例">务必成功的测试用例</a></h2>
|
|
|
<p>接着就是测试驱动的第二步：编写注定成功的测试。当然，前提条件是实现我们的 <code>search</code> 函数。它包含以下步骤：</p>
|
|
|
<ul>
|
|
|
<li>遍历迭代 <code>contents</code> 的每一行</li>
|
|
|
<li>检查该行内容是否包含我们的目标字符串</li>
|
|
|
<li>若包含，则放入返回值列表中，否则忽略</li>
|
|
|
<li>返回匹配到的返回值列表</li>
|
|
|
</ul>
|
|
|
<h3 id="遍历迭代每一行"><a class="header" href="#遍历迭代每一行">遍历迭代每一行</a></h3>
|
|
|
<p>Rust 提供了一个很便利的 <code>lines</code> 方法将目标字符串进行按行分割:</p>
|
|
|
<pre><pre class="playground"><code class="language-rust edition2021"><span class="boring">#![allow(unused)]
|
|
|
</span><span class="boring">fn main() {
|
|
|
</span>// in lib.rs
|
|
|
pub fn search<'a>(query: &str, contents: &'a str) -> Vec<&'a str> {
|
|
|
for line in contents.lines() {
|
|
|
// do something with line
|
|
|
}
|
|
|
}
|
|
|
<span class="boring">}</span></code></pre></pre>
|
|
|
<p>这里的 <code>lines</code> 返回一个<a href="https://course.rs/advance/functional-programing/iterator.html">迭代器</a>，关于迭代器在后续章节会详细讲解，现在只要知道 <code>for</code> 可以遍历取出迭代器中的值即可。</p>
|
|
|
<h3 id="在每一行中查询目标字符串"><a class="header" href="#在每一行中查询目标字符串">在每一行中查询目标字符串</a></h3>
|
|
|
<pre><pre class="playground"><code class="language-rust edition2021"><span class="boring">#![allow(unused)]
|
|
|
</span><span class="boring">fn main() {
|
|
|
</span>// in lib.rs
|
|
|
pub fn search<'a>(query: &str, contents: &'a str) -> Vec<&'a str> {
|
|
|
for line in contents.lines() {
|
|
|
if line.contains(query) {
|
|
|
// do something with line
|
|
|
}
|
|
|
}
|
|
|
}
|
|
|
<span class="boring">}</span></code></pre></pre>
|
|
|
<p>与之前的 <code>lines</code> 函数类似，Rust 的字符串还提供了 <code>contains</code> 方法，用于检查 <code>line</code> 是否包含待查询的 <code>query</code>。</p>
|
|
|
<p>接下来，只要返回合适的值，就可以完成 <code>search</code> 函数的编写。</p>
|
|
|
<h3 id="存储匹配到的结果"><a class="header" href="#存储匹配到的结果">存储匹配到的结果</a></h3>
|
|
|
<p>简单，创建一个 <code>Vec</code> 动态数组，然后将查询到的每一个 <code>line</code> 推进数组中即可：</p>
|
|
|
<pre><pre class="playground"><code class="language-rust edition2021"><span class="boring">#![allow(unused)]
|
|
|
</span><span class="boring">fn main() {
|
|
|
</span>// in lib.rs
|
|
|
pub fn search<'a>(query: &str, contents: &'a str) -> Vec<&'a str> {
|
|
|
let mut results = Vec::new();
|
|
|
|
|
|
for line in contents.lines() {
|
|
|
if line.contains(query) {
|
|
|
results.push(line);
|
|
|
}
|
|
|
}
|
|
|
|
|
|
results
|
|
|
}
|
|
|
<span class="boring">}</span></code></pre></pre>
|
|
|
<p>至此，<code>search</code> 函数已经完成了既定目标，为了检查功能是否正确，运行下我们之前编写的测试用例:</p>
