java.lang.AssertionError：比较预期的错误消息

Question

实际值和预期值仍然相同，为什么会出现断言错误？

Utility.java

public  String getValue(String filename, String key) throws IOException {
    FileInputStream fis = new FileInputStream(".\\testdata\\" + filename + ".properties");
    Properties p = new Properties();
    p.load(fis);
    String value = p.getProperty(key);
    return value;   
}

errormessage.properties文件

errormessage：×\ n错误消息\ nUsername字段为必填。 \ n密码为必填字段。

步骤定义代码

@And("^User should get errormessage$")
public void user_should_get_error_message() throws Throwable {
    this.errormessage=this.utility.getValue("errormessage", "errormessage");
    Assert.assertEquals(this.errormessage,this.login.getError(), "Comparing error message");
}

错误：

java.lang.AssertionError: Comparing error message expected [×
Error message

Password field is required.] but found [× 
Error message

第二个（找到的）文本在“用户名字段为必填项。”之后有一个多余的空格，这不在您的预期消息中。

×
Error message
Username field is required.
Password field is required.
