assertNotIsWritable()函数是PHPUnit中的内置函数,用于断言assertNotIswritable是否指定了文件名不可写。如果给定的文件名不存在且不可写,则该断言将返回true,否则返回false。如果为真,则通过断言的测试用例,否则测试用例失败。
用法:
assertNotIsWritable(string $filename[, string $message = ''])
参数:该函数接受两个参数,如上面的语法所示。参数说明如下:
- $filename:此参数是表示文件名的任何类型的字符串。
- $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assertNotIsWritable()函数:
范例1:
PHP
<?php
use PHPUnit\Framework\TestCase;
class GeeksPhpunitTestCase extends TestCase
{
public function testNegativeTestcaseForassertNotIsWritable()
{
$filename = "/home/lovely/Documents/php/phpunit";
// Assert function to test whether given
// file name is not writable
$this->assertNotIsWritable(
$filename,
"filename is not writable"
);
}
}
?>
输出:
PHPUnit 8.5.8 by Sebastian Bergmann and contributors. F 1 / 1 (100%) Time:85 ms, Memory:10.00 MB There was 1 failure: 1) GeeksPhpunitTestCase::testNegativeTestcaseForassertNotIsWritable filename is writable or Not Failed asserting that "/home/lovely/Documents/php/phpunit" is not writable. /home/lovely/Documents/php/test.php:16 FAILURES! Tests:1, Assertions:1, Failures:1.
范例2:
PHP
<?php
use PHPUnit\Framework\TestCase;
class GeeksPhpunitTestCase extends TestCase
{
public function testPositiveTestcaseForassertNotIsWritable()
{
$filename = "/home/lovely/Documents/php/phpunit/geeksforgeeks";
// Assert function to test whether given
// file name is not writable
$this->assertNotIsWritable(
$filename,
"filename is writable or not"
);
}
}
?>
输出:
PHPUnit 8.5.8 by Sebastian Bergmann and contributors. . 1 / 1 (100%) Time:87 ms, Memory:10.00 MB OK (1 test, 1 assertion)
