PHPUnit assertLessThan()函数
assertLessThan()函数是 PHPUnit 中的内置函数,用于断言实际获取的值是否小于预期值。如果实际值小于预期值,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:
assertLessThan(mixed $expected, mixed $actual
[, string $message = ''])
参数:此函数接受三个参数,如上所述,如下所述:
- $expected:此参数是表示预期数据的任何类型的数值。
- $actual:此参数是代表实际数据的任何类型的数值。
- $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。
下面的例子说明了 PHPUnit 中的 assertLessThan()函数:
示例 1:
PHP
assertLessThan(
$expected,
$actual,
"actual value is not less than expected"
);
}
}
?>
PHP
assertLessThan(
$expected,
$actual,
"actual value is not less than expected"
);
}
}
?>
