PHPUnit assertIsNotArray() Function

The assertIsNotArray() function is a builtin function in PHPUnit and is used to assert whether the given variable is not an array. This assertion will return true in the case if the given variable is not array else returns false. In case of true the asserted test case got passed else test case got failed.

Syntax:

assertIsNotArray($actual[, $message = ''])

Parameters: This function accepts two parameters as mentioned above and described below:

• $variable: This parameter is of any type of variable 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 assertIsNotArray() function in PHPUnit:

Example 1:

class GeeksPhpunitTestCase extends TestCase
{
    public function testNegativeForassertIsNotArray()

    {
     $variable  = array ("apple/banana");
         // Assert function to test whether assert
        //  variable is array
        $this->assertIsNotArray(
            $variable,
            "assert variable is array"
        );

    }
