PHPUnit | assertArraySubset()函数
assertArraySubset ()函数是 PHPUnit 中的内置函数,用于断言具有子集的数组。如果数组包含提供的子集,则此断言将返回 true,否则返回 false,如果为 true,则断言的测试用例得到通过否则测试用例失败。
语法:
assertArraySubset(array $subset, array $array[, bool $strict = false, string $message = ''])
参数:此函数接受四个参数,如上述语法所示。参数说明如下:
- $subset :此参数表示要包含在数组中的子集。
- $array :这个参数是一个数组,断言函数将检查它是否包含子集。
- $strict :这个参数是一个标志,用于比较数组中对象的身份。
- $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 assertArraySubset()函数:
程序一:
"value b", "b" =>" value b");
$subset = array("a"=> "value a");
// assert function to test whether 'subset' is a subset of array
$this->assertArraySubset($subset, $testArray, false, "testArray doesn't contains subset as subset") ;
}
}
?>
