需要为单元测试选择断言
本文关键字:选择 断言 单元测试 | 更新日期: 2023-09-27 18:22:08
这是我的代码:
public int GetTotalIssuedCount()
{
var storeCode = Store.Current.Code.ToLower();
return (from i in Context.Instance.EduContainer.IssueDetailsSet
where i.Status.ToLower() == "issued" && i.Store.Code == storeCode
select i).Count();
}
这是我的测试代码:
[TestMethod]
public void GetTotalIssuedCountTest()
{
StoreRepository sr = new StoreRepository();
Assert.IsInstanceOfType();
}
哪种断言方法在这里合适?
在给定底层数据集状态的情况下,您需要断言count是否与您期望的相匹配:
[TestMethod]
public void GetTotalIssuedCountTest()
{
// The 5 is exemplary value -
// you need to determine actual one basing data set contents
const int expectedIssuedCount = 5;
var storeRepository = new StoreRepository();
// Here you'll most likely need to prepare fake data set
var actualIssuedCount = storeRepository.GetTotalIssuedCount();
Assert.AreEqual(expectedIssuedCount, actualIssuedCount);
}
要使其工作,您需要设置fake数据集(EduContainer.IssueDetailsSet
),您的方法将访问该数据集。您很可能需要mock和依赖项注入来实现这一点。
