PHPUnit9.0 断言-assertStringContainsStringIgnoringCase()

assertStringContainsStringIgnoringCase(string $needle, string $haystack[, string $message = ''])

PHPUnit9.0 断言集合

当 ​$needle​ 不是 ​$haystack​ 的子字符串时报告错误，错误讯息由 ​$message​ 指定。
在 ​$haystack​ 中搜索 ​$needle​ 时，忽略大小写差异。
​assertStringNotContainsStringIgnoringCase()​ 是与之相反的断言，接受相同的参数。
