Syntax:assertEqualsCanonicalizing (mixed $expected, mixed $actual, string $message = ’’)
Parameters: This function takes three parameters as shown in the above syntax. The parameters are described below: - $Expected: This parameter is a mixed variable that denotes the expected value.
- $actual: this parameter is a mixed variable that denotes the actual value to compare with the expected one.
- $message: this parameter accepts a string value. When the test case failed, this string message was displayed as an error message.
The following programs illustrate the assertEqualsCanonicalizing() function in PHPUnit: Program 1: use
PHPUnitFrameworkTestCase;
class
GeeksPhpunitTestCase
extends
TestCase
{
public
function
testNegativeTestcaseForAssertEqualsCanonicalizing()
{
$expected
=
array
(1, 2, 3, 4);
$actual
=
array
(2, 1, 2, 4);
// Validate function to check if expected
// and actual canonically equal or not.
$this
-> assertEqualsCanonicalizing (
$expected
,
$actual
,
"expected and actual are not canonically equals"
);
}
}
?>

Note: To run testcases with PHPUnit steps follows from here . Also assertEqualsCanonicalizing() is supported by phpunit 7 and up.
