Syntax:assertStringNotContainsStringIgnoringCase (string $substring, string $string, string $message = ’’])
Parameters: This function takes three parameters as shown in the above syntax. The parameters are described below:
- $substring: this parameter represents a string that will be a substring of the given string.
- $string: this parameter is a string for which the assert function will check if it contains a substring (ignoring case) or not.
- $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 assertStringNotContainsStringIgnoringCase() function: Program 1: use
PHPUnitFrameworkTestCase;
class
GeeksPhpunitTestCase
extends
TestCase
{
public
function
testNegativeTestcaseForAssertStringNotContainsStringIgnoringCase()
{
$testString
=
" geekforgeek "
;
$substring
=
"gEek"
;
// Assert function to check if ’ geek ’ substring
// testString ignoring case sensitivity
$this
-> assertStringNotContainsStringIgnoringCase (
$substring
,
$testString
,
"testString contains’ gEek’ as substring "
);
}
}
?>
