PHPunit | assertEqualsCanonicalizing() Function
The assertEqualsCanonicalizing() function is a builtin function in PHPUnit and is used to assert whether expected and actual variables are canonically equals. Canonical equals mean before actual comparison both array will be sorted and compared. This assertion will return true in the case if expected and actual are same, else return false. In case of true the asserted test case got passed else test case got failed.
assertEqualsCanonicalizing( mixed $expected, mixed $actual, string $message = '' )
Parameters: This function accepts three parameters as shown in the above syntax. The parameters are described below:
- $expected: This parameter is a mixed variable which denotes the expected value.
- $actual: This parameter is a mixed variable which denotes the actual value to compare with expected.
- $message: This parameter takes string value. When the testcase got failed this string message got displayed as error message.
