PHPUnit assertIsBool() Function
The assertIsBool() function is a builtin function in PHPUnit and is used to assert whether the actually obtained value is Bool or not. This assertion will return true in the case if the actual value is the Bool else returns false. In case of true the asserted test case got passed else test case got failed.
Syntax:
assertIsBool($actual[, $message = ''])
Parameters: This function accepts two parameters as mentioned above and described below:
- $actualvalue: This parameter is of any type which represents the actual data.
- $message: This parameter takes a string value. When the test case got failed this string message got displayed as an error message.
Below examples illustrate the assertIsBool() function in PHPUnit:
Example 1:
PHP
<?php
use PHPUnit\Framework\TestCase;
class GeeksPhpunitTestCase extends TestCase
{
public function testNegativeForassertIsNotBooltrue()
{ $actual = 420;
$this ->assertIsBool(
$actual ,
"actual value is Bool or not"
);
}
public function testNegativeForassertIsNotBoolFalse()
{
$actual = 220;
$this ->assertIsBool(
$actual ,
"actual value is Bool or not"
);
}
}
?>
