assertNotFalse()函数是PHPUnit中的内置函数,用于断言条件值是否为true。如果条件值为true,则此断言将返回true,否则返回false。如果为true,则声明的测试用例通过,否则测试用例失败。
用法:
assertNotFalse(bool $condition[, string $message = ''])
参数:此函数接受上述和以下所述的三个参数:
- $condition:此参数是代表true或false的任何类型的值。
- $message:此参数采用字符串值。当测试用例失败时,此字符串消息将显示为错误消息。
以下示例说明了PHPUnit中的assertNotfalse()函数:
范例1:
PHP
<?php
use PHPUnit\Framework\TestCase;
class GeeksPhpunitTestCase extends TestCase
{
public function testNegativeTestcaseForassertNotFalse()
{
$condition = false;
// Assert function to test whether
// condition value is true or not
$this->assertNotFalse(
$condition,
"condition is true or false"
);
}
}
?>
输出:
PHPUnit 8.5.8 by Sebastian Bergmann and contributors. F 1 / 1 (100%) Time:95 ms, Memory:10.00 MB There was 1 failure: 1) GeeksPhpunitTestCase::testNegativeTestcaseForassertNotFalse condition is true or false Failed asserting that false is not false. /home/lovely/Documents/php/test.php:17 FAILURES! Tests:1, Assertions:1, Failures:1.
范例2:
PHP
<?php
use PHPUnit\Framework\TestCase;
class GeeksPhpunitTestCase extends TestCase
{
public function testPsitiveTestcaseForassertNotFalse()
{
$condition = "false";
// Assert function to test whether
// condition value is true or not
$this->assertNotFalse(
$condition,
"condition is true or false"
);
}
}
?>
输出:
PHPUnit 8.5.8 by Sebastian Bergmann and contributors. . 1 / 1 (100%) Time:91 ms, Memory:10.00 MB OK (1 test, 1 assertion)
