java - 测试字符串 Junit

Question

给定一个 toString 方法:

public String toString()
{
    String accountString;
    NumberFormat money = NumberFormat.getCurrencyInstance();

    accountString = cust.toString();
    accountString += " Current balance is " + money.format (balance);
    return accountString;
}

我如何使用 Junit 对其进行测试？

Answer 1

这是我的做法:

public class AccountTest
{
    @Test
    public void testToString()
    {
        Account account = new Account(); // you didn't supply the object, so I guessed
        String expected = ""; // put the expected value here
        Assert.assertEquals(expected, account.toString());
    }
}
