PHPUnit assertXmlStringEqualsXmlString() Function
The assertXmlStringEqualsXmlString() function is a builtin function in PHPUnit and is used to assert whether the actual XML string equals to expected XML string or not. This assertion will return true in the case if the expected XML string is the same as the actual XML string else returns false. In case of true the asserted test case got passed else test case got failed.
Syntax:
assertXmlStringEqualsXmlString(string $expectedXml,
string $actualXml[, string $message = ''])
Parameters: This function accepts three parameters as mentioned above and described below:
- $expectedXmlString: This parameter is of any type which represents the expected XML string.
- $actualXmlString: This parameter is of any type which represents the actual XML String.
- $message: This parameter takes a string value. When the test case got failed this string message got displayed as an error message.

$expectedxmlString = '<foo><bazx></bazx></foo>' ;
$actualxmlString = '<foo><baz></baz></foo>' ;
$this ->assertXmlStringEqualsXmlString(
$actualxmlString ,
