The assertNotEmpty() function is a builtin function in PHPUnit and is used to assert whether the data holder specified is non-empty or not. This assertion will return true in the case if the data holder provided is non-empty else return false. In case of true the asserted test case got passed else test case got failed.
Syntax:
assertNotEmpty( mixed $dataHolder, string $message = '' )
Parameters: This function accepts two parameters as shown in the above syntax. The parameters are described below:
- $dataHolder: This parameter is of any type which represent the data holder to be asserted.
- $message: This parameter takes string value. When the testcase got failed this string message got displayed as error message.
Below programs illustrate the assertNotEmpty() function in PHPUnit:
Program 1:
<?php use PHPUnit\Framework\TestCase;   class GeeksPhpunitTestCase extends TestCase {     public function testNegativeTestcaseForAssertNotEmpty()     {         $dataHolder = '';           // Assert function to test whether given         // data holder (variable) is non-empty or not         $this->assertNotEmpty(             $dataHolder,             "data holder is empty"        );     } }   ?> |

Program 2:
<?php use PHPUnit\Framework\TestCase;   class GeeksPhpunitTestCase extends TestCase {     public function testPositiveTestcaseForAssertNotEmpty()     {         $dataHolder = 'test data';           // Assert function to test whether given         // data holder (variable) is non-empty or not         $this->assertNotEmpty(             $dataHolder,             "data holder is empty"        );     } }   ?> |

Note: To run testcases with phpunit follow steps from here. Also, assertNotEmpty() is supported by phpunit 7 and above.
