PHPUnit assertTrue() Function
Last Updated :
07 Aug, 2020
The assertTrue() function is a builtin function in PHPUnit and is used to assert whether the assert value is true or not. This assertion will return true in the case if the assert value is true else returns false. In case of true the asserted test case got passed else test case got failed.
Syntax:
assertTrue(bool $condition[, string $message = ''])
Parameters: This function accepts two parameters as mentioned above and described below:
- $assertvalue: This parameter is of any type of variable which represents the assert 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 assertTrue() function in PHPUnit:
Example 1:
PHP
<?php
use PHPUnit\Framework\TestCase;
class GeeksPhpunitTestCase extends TestCase
{
public function testNegativeForassertTrue()
{
$assertvalue = false;
$this ->assertTrue(
$assertvalue ,
"assert value is true or not"
);
}
}
?>
