PHPUnit assertStringStartsNotWith()函数
assertStringStartsNotWith()函数是 PHPUnit 中的内置函数,用于断言实际字符串是否不以预期的前缀字符串开头。如果实际字符串不以预期的前缀字符串开头,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:
assertStringStartsNotWith(string $prefix,
string $string[, string $message = ''])
参数:此函数接受三个参数,如上所述,如下所述:
- $expectedprefix:这个参数是代表期望前缀字符串的任何类型。
- $actualstring:这个参数是代表实际字符串的任何类型。
- $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。
