The assertStringNotMatchesFormat() function is a builtin function in PHPUnit and is used to assert whether the difference between the given string and given format. This assertion will return true in the case if the given string not matched with the type of format else returns false. In case of true the asserted test case got passed else test case got failed.
Syntax:
assertStringNotMatchesFormat(string $format,
string $string[, string $message = ''])
Parameters: This function accepts three parameters as shown in the above syntax. The parameters are described below:
- $format: This parameter is represented as a pre-established layout for data.
- $string: This parameter is of any type which represents the string.
- $message: This parameter takes a string value. When the test case got failed this string message got displayed as an error message.
