PHPunit | AssertEqualsCanonicalizing () Function

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" ); } }  
?>
Output:
PHPUnit 8.2.5 by Sebastian Bergmann and contributors. F 1/1 (100%) Time: 65 ms, Memory: 10.00 MB There was 1 failure: 1) GeeksPhpunitTestCase::testNegativeTestcaseForAssertEqualsCanonicalizing expected and actual are not canonically equals Failed asserting that two arrays are equal. --- Expected +++ Actual @@ @@ Array (0 = > 1 1 = > 2 - 2 = > 3 + 2 = > 2 3 = > 4) / home / shivam / Documents / engineer /phpunit/abc.php:13 FAILURES! Tests: 1, Assertions: 1, Failures: 1. 
Program 2: use PHPUnitFrameworkTestCase; class GeeksPhpunitTestCase extends TestCase { public function testPositiveTestcaseForAssertEqualsCanonicalizing() { $expected = array (1, 2, 3, 4); $actual = array (2, 1, 3, 4); // Validate function to check if expected // and actual canonically equal or not. $this -> assertEqualsCanonicalizing ( $expected , $actual , "expected and actual are not canonically equals" ); } }  
?>
Output:
PHPUnit 8.2.5 by Sebastian Bergmann and contributors. ... 1/1 (100%) Time: 67 ms, Memory: 10.00 MB OK (1 test, 1 assertion) 
Note: To run testcases with PHPUnit steps follows from here . Also assertEqualsCanonicalizing() is supported by phpunit 7 and up.
