<p>If you've written or seen automated tests in PHP, you'll have seen lines like this:</p>
|
||
|
|
|
||
|
|
<pre><code class="php">self::assertTrue(FALSE);
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<p>But, did you know assertions can be used outside of tests.</p>
|
||
|
|
|
||
|
|
<p>PHP has an <code>assert()</code> function that can be used anywhere.</p>
|
||
|
|
|
||
|
|
<p>For example, if I had this code:</p>
|
||
|
|
|
||
|
|
<pre><code class="php">$node = Node::load(1);
|
||
|
|
|
||
|
|
assert($node instanceof NodeInterface);
|
||
|
|
assert($node->bundle() === 'page');
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<p>I know <code>$node</code> is a node with the correct bundle type and I can continue.</p>
|
||
|
|
|
||
|
|
<p>I've made my assumptions explicit.</p>
|
||
|
|
|
||
|
|
<p>If <code>$node</code> is not the correct type or returns an unexpected bundle, the assertion will fail and an Exception will be thrown.</p>
|
||
|
|
|
||
|
|
<p>I think this is better than assuming or hoping the values are as you expect, and it also makes the intent of the code much easier to see and understand.</p>
|
||
|
|
|
||
|
|
<p>If you haven't tried <code>assert()</code> before, give it a try.</p>
