Question

If I am correct, SimpleTest will allow you to assert a PHP error is thrown. However, I can’t figure out how to use it, based on the documentation. I want to assert that the object I pass into my constructor is an instance of MyOtherObject

class Object {     public function __construct(MyOtherObject $object) {         //do something with $object     } }  //...and in my test I have... public function testConstruct_ExpectsAnInstanceOfMyOtherObject() {     $notAnObject = 'foobar';     $object = new Object($notAnObject);     $this->expectError($object); } 

Where am I going wrong?

Type hinting throws E_RECOVERABLE_ERROR which can be caught by SimpleTest since PHP version 5.2. The following will catch any error containing the text ‘must be an instance of’. The constructor of PatternExpectation takes a perl regex.

public function testConstruct_ExpectsAnInstanceOfMyOtherObject() {     $notAnObject = 'foobar';     $this->expectError(new PatternExpectation('/must be an instance of/i'));     $object = new Object($notAnObject); }
