java - 尝试找到 Maven 的 InvoiceStorage 依赖项

Question

我正在遵循一个具有外部类 InvoiceStorage 的教程，我认为，我对此非常菜鸟，但 java 无法解析该 InvoiceStorage 符号，所以我认为我需要一个教程中未显示的依赖项

教程链接: https://semaphoreci.com/community/tutorials/stubbing-and-mocking-with-mockito-2-and-junit

package com.mokitoTutorial.app;

import com.clusterra.email.sender.EmailSender;


public class LateInvoiceNotifier {
    private final EmailSender emailSender;
    private final InvoiceStorage invoiceStorage;

    public LateInvoiceNotifier(final EmailSender emailSender, final InvoiceStorage invoiceStorage){
        this.emailSender = emailSender;
        this.invoiceStorage = invoiceStorage;
    }

    public void notifyIfLate(Customer customer)
    {
        if(invoiceStorage.hasOutstandingInvoice(customer)){
            emailSender.sendEmail(customer);
        }
    }
}

Answer 1

在这篇文章中，作者只是提供了一个如何使用mockito的示例。您可以从上面的文章中看到以下内容。

In a real system, the InvoiceStorage class is actually a web service that connects with an external legacy CRM system which is slow. A unit test could never make use of such as web service.

作者指的是一个名为InvoiceStorage的类，它是例如。没有依赖性。您可以按照这篇文章创建自己的类来测试。
