The assertXmlStringEqualsXmlFile() function is a builtin function in PHPUnit and is used to assert whether the actual XML file Content is 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 file content else returns false. In case of true the asserted test case got passed else test case got failed.
Syntax:
assertXmlStringEqualsXmlFile(string $expectedFile,
string $actualFile[, string $message = ''])
Parameters: This function accepts three parameters as shown in the above syntax. The parameters are described below:
- $expectedXmlString: This parameter is of any type which represents the expected XML string.
- $actualXmlFile: This parameter is of any type which represents the actual XML File Path.
- $message: This parameter takes a string value. When the test case got failed this string message got displayed as an error message.
