Are there any potential pitfalls to be aware of when using PHPUnit for testing PHP programs?

One potential pitfall when using PHPUnit for testing PHP programs is the risk of relying too heavily on mock objects, which can lead to overly complex and brittle tests. To avoid this, it's important to strike a balance between using mocks for isolating dependencies and testing actual behavior. 

// Example of using a mock object in PHPUnit
$mock = $this->getMockBuilder(SomeClass::class)
             ->disableOriginalConstructor()
             ->getMock();

$mock->method('someMethod')
     ->willReturn('someValue');

$this->assertEquals('someValue', $mock->someMethod());
