phpunit.assertTrue

Code example

<?php declare(strict_types = 1);

use PHPUnit\Framework\TestCase;

class MyTest extends TestCase
{
	public function testSomething(): void
	{
		$this->assertSame(true, $this->isValid());
	}
}

Why is it reported?

When the expected value in assertSame() is the literal true, using assertTrue() is more idiomatic and produces clearer failure messages. PHPUnit provides dedicated assertion methods for boolean values.

How to fix it

Replace assertSame(true, ...) with assertTrue(...):

-$this->assertSame(true, $this->isValid());
+$this->assertTrue($this->isValid());
