PHPUnit assertFileEquals()函数

assertFileEquals()函数是 PHPUnit 中的内置函数,用于断言实际文件内容是否与预期文件的内容完全相同。如果预期文件内容与实际文件内容相同,则此断言将返回 true,否则返回 false。如果为真,则断言的测试用例通过,否则测试用例失败。

句法:

assertFileEquals(string $expected, 
      string $actual[, string $message = ''])

参数:此函数接受三个参数,如上所述,如下所述:

  • $expected:这个参数是一个字符串,代表预期的文件路径。
  • $actual:这个参数是一个字符串,代表实际的文件路径。
  • $message:此参数采用字符串值。当测试用例失败时,此字符串消息显示为错误消息。

下面的程序说明了 PHPUnit 中的 assertFileEquals()函数:

示例 1:

PHP
assertFileEquals(
            $expected, 
            $actual, 
"actual file content is not equals to expected file content"
        ); 
    } 
} 
    
?>


PHP
assertFileEquals(
            $expected, 
            $actual, 
"actual file content is not equals to expected file content"
        ); 
    } 
} 
    
?>
