Appendix A. Assertions

This appendix lists the various assertion methods that are available.

assertArrayHasKey()

assertArrayHasKey(mixed $key, array $array[, string $message = ''])

Reports an error identified by $message if $array does not have the $key.

assertArrayNotHasKey() is the inverse of this assertion and takes the same arguments.

Example A.1: Usage of assertArrayHasKey()

<?php
class ArrayHasKeyTest extends PHPUnit_Framework_TestCase
{
    public function testFailure()
    {
        $this->assertArrayHasKey('foo', array('bar' => 'baz'));
    }
}
?>

assertClassHasAttribute()

assertClassHasAttribute(string $attributeName, string $className[, string $message = ''])

assertEquals()

assertEquals(mixed $expected, mixed $actual[, string $message = ''])

Reports an error identified by $message if the two variables $expected and $actual are not equal.

assertNotEquals() is the inverse of this assertion and takes the same arguments.

assertAttributeEquals() and assertAttributeNotEquals() are convenience wrappers that use a public, protected, or private attribute of a class or object as the actual value.

Of note, when using assertEquals() and assertNotEquals() where one variable is the number zero (either integer or float) and the other variable is a string, the types of the variables are also compared (i.e. === comparison operator, not the normal == comparison operator). This can be problematic in the one case where it is assumed that 0 == "" is true (due to type-juggling), but is in fact false when using assertEquals() or assertNotEquals().

Example A.13: Usage of assertEquals()

<?php
class EqualsTest extends PHPUnit_Framework_TestCase
{
    public function testFailure()
    {
        $this->assertEquals(1, 0);

assertThat()

More complex assertions can be formulated using the PHPUnit_Framework_Constraint classes. They can be evaluated using the assertThat() method. Example A.42 shows how the logicalNot() and equalTo() constraints can be used to express the same assertion as assertNotEquals().

assertThat(mixed $value, PHPUnit_Framework_Constraint $constraint[, $message = ''])

Reports an error identified by $message if the $value does not match the $constraint.

Example A.42: Usage of assertThat()

<?php
class BiscuitTest extends PHPUnit_Framework_TestCase
{
    public function testEquals()
    {
        $theBiscuit = new Biscuit('Ginger');
        $myBiscuit  = new Biscuit('Ginger');

        $this->assertThat(
          $theBiscuit,
          $this->logicalNot(
            $this->equalTo($myBiscuit)
          )
        );
    }
