PHP PHPUnit assertFileIsReadable()用法及代码示例


assertFileIsReadable()函数是PHPUnit中的内置函数,用于断言指定的assertfile是否是可读取的文件名。如果给定的文件名存在且可读,则此断言将返回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:

assertFileIsReadable(string $filename[, string $message = ''])

参数:此函数接受上述和以下描述的两个参数:

  • $filename:此参数是表示文件名的字符串。
  • $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assertFileIsReadable()函数:

范例1:



PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForAssertFileIsReadable()  
    {  
        $filename = "/home/lovely/Documents/phpunit";  
    
        // Assert function to test whether the given  
        // file name either exists and readable  
        $this->assertFileIsReadable(  
            $filename,  
            "File name  exists and readable"
        );  
    }  
}  
    
?> 

输出:

PHPUnit 8.5.8 by Sebastian Bergmann and contributors.

F                                                       1 / 1 (100%)

范例2:

PHP

<?php

class GeeksPhpunitTestCase extends TestCase  
{  
    public function testPositiveTestcaseForAssertFileIsReadable()  
    {  
        $filename = "/home/lovely/Documents/php";  
    
        // Assert function to test whether the given  
        // file name either exists and readable  
        $this->assertFileIsReadable(  
            $filename,  
            "File name  exists and readable"
        );  
    }  
}  
    
?>
