Question

我在服务类中有转移方法，我想为此方法创建一个测试，以检查转移值是否有效。

我要测试的方法是这样：

public void transfer(Account destiny, double value) {
        Account origin = new Account();
        if (value<= origin.getBalance()) {
            this.withdraw(value);
            destiny.setDeposit(value);
        }
    }

我现在开始修补测试。感谢您的理解。

Answer 1

我首先建议您重构该方法。您希望将其传递给方法，而不是在方法内部实例化/创建/查找原始帐户。因此，您的新方法签名应如下所示

public void transfer(Account destiny, Account origin, double value) {
   ...
}

完成后，您的快乐路径测试用例应该看起来像这样

Account destiny = new Account();
destiny.setBalance(100); // Some way to set balance
Account origin = new Account();
origin.setBalance(75); // Some way to set balance

transfer(destiny,origin,25); //Call your method

assertEquals(origin.getBalance(), 50);
assertEquals(origin.getBalance(), 125);

您还可以在此处测试否定情况，即原始余额小于转账金额，因此不会发生转账，并且两个帐户的余额都不变。

如何处理，请检查余额是否已更改
