PHPUnit assertStringEqualsFile()函数
assertStringEqualsFile()函数是PHPUnit中的内置函数,用于断言获取的实际字符串内容是否等于预期文件。如果预期文件内容与实际字符串内容相同,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:
assertStringEqualsFile(string $expectedFile,
string $actualString[, string $message = ''])
参数:此函数接受三个参数,如上所述,如下所述:
- $expectedfile:这个参数是代表预期文件的任何类型。
- $actualstring:这个参数是代表实际字符串内容的任何类型。
- $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。
