This appendix lists the various assertion methods that are available.
assertArrayHasKey(mixed $key, array $array[, string $message = ''])

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); } public function testFailure2() { $this->assertEquals('bar', 'baz'); } public function testFailure3() { $this->assertEquals("foo\nbar\nbaz\n", "foo\nbah\nbaz\n"); } public function testFailure4() { $this->assertEquals("", 0) } } ?>

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) ) ); } } ?>
