PHP PHPUnit assertStringStartsNotWith()用法及代码示例

assertStringStartsNotWith()函数是PHPUnit中的内置函数，用于断言实际字符串是否不是以预期的前缀字符串开头。如果实际字符串不是以预期的前缀字符串开头，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:

assertStringStartsNotWith(string $prefix, 
string $string[, string $message = ''])

参数：此函数接受上述和以下所述的三个参数：

$expectedprefix:此参数可以是代表所需前缀字符串的任何类型。
$actualstring:此参数可以是代表实际字符串的任何类型。
$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assertStringStartsNotWith()函数：

范例1：

PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForassertStringStartsNotWith() 
    {  
        $expectedprefix = ('dis'); 
        $actualstring = ('disagree'); 
    
        // Assert function to test whether  
        // actual string content doesn't starts  
        // with expected prefix string content 
        $this->assertStringStartsNotWith( 
            $expectedprefix, 
            $actualstring,  
            "actual string content doesn't start with  
             expected prefix content" 
        );  
    }  
}  
    
?>
