PHPUnit assertInfinite()函数
assertInfinite()函数是PHPUnit中的内置函数,用于断言实际获取的值是否为 INF。如果实际值为 INF,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:
assertInfinite(mixed $variable[, string $message = ''])
参数:该函数接受两个参数,如下所述:
- $actualvariable:这个参数是代表实际值的任何类型的变量。
- $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。
