PHPUnit assertIsNotIterable()函数
assertIsNotIterable()函数是 PHPUnit 中的内置函数,用于断言给定变量是否不是 Iterable。如果给定变量不是可迭代的,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:
assertIsNotIterable($actual[, $message = ''])
参数:该函数接受上面提到的两个参数,如下所述:
- $variable:此参数是代表实际数据的任何类型的变量。
- $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。
