      <p>In <a href="/daily/2024/05/31/putting-glue-on-pizza">yesterday's email</a>, I mentioned some of the recent issues I've seen from AI tools.</p>

      <p>I'm wary of any code generated by AI, as I've often found it to be incorrect.</p>

      <p>If you rely on AI-generated code, I'd be especially wary if it also generates the automated tests.</p>

      <p>Automated tests verify your application works as expected, so you need to ensure they are testing the correct things and the logic is correct.</p>

      <p>Can you make a test purposely fail by changing some logic within the test or implementation code?</p>

      <p>Is it clear what each test is doing?</p>

      <p>Are the tests running the implementation code or just testing mocks or running meaningless assertions like <code>self::assertTrue(TRUE)</code>?</p>

      <p>Writing tests is about building confidence, which you can't do if you don't know what your tests are testing or how.</p>
