【问题描述】:
我在 .NET Web API 2 项目中的控制器端点上应用 NUnit 集成测试,该项目的模型和控制器是通过 Entity code first from database 生成的。
我不知道应该测试控制器的哪些部分。 最后,我们只是希望能够自动化“具有“x”角色的用户可以获取这些数据吗?”
查看此控制器的GET 部分,您将测试哪些部分以及您的推理是什么?
namespace api.Controllers.myNamespace
{
public class myController : ApiController
{
private string strUserName;
private string strError = "";
private string strApiName = "myTable";
private myDatabase db = new myDatabase();
// ----------------------------------------------------------------------
// GET: api/path
public IQueryable<myTable> GetmyTable()
{
try
{
this.strUserName = this.getUserName();
if
(
// ----- authorize -----
db.view_jnc_role_api_permission.Count
(
view =>
(
view.permission == "get"
&& view.apiName == this.strApiName
&& view.userName == this.strUserName
)
) == 1
// ----- /authorize -----
)
{
// ----- get -----
IQueryable<myTable> data =
from tbl in db.myTable
where tbl.deleted == null
select tbl;
// ----- /get -----
return data;
}
else
{
strError = "Unauthorized.";
throw new HttpResponseException(HttpStatusCode.Forbidden);
}
}
catch (Exception ex)
{
if (strError.Length == 0)
{
if (this.showException())
{
strError = ex.ToString();
}
}
throw new HttpResponseException(ControllerContext.Request.CreateErrorResponse(HttpStatusCode.Forbidden, strError));
}
}
}
作为参考,这是我到目前为止所拥有的。我正在定义的这些私有字段中的一些不应该在这里 - 目前正试图通过 AssemblyInfo.cs 从我的测试项目中访问私有方法来解决这个问题:
namespace api.myNamespace
{
[TestFixture]
public class myController : ApiController
{
private string strUserName;
private string strError = "";
private string strApiName = "myTable";
private myDb db = new myDb();
// Using TransactionScope to (hopefully) prevent integration test's changes to database from persisting
protected TransactionScope TransactionScope;
// Instantiate _controller field
private myController _controller;
[SetUp]
public void SetUp() {
TransactionScope = new TransactionScope(TransactionScopeOption.RequiresNew);
// It's possible that one test may leave some state which could impact subsequent tests - so we must reinstantiate _controller at the start of each new test:
_controller = new myController();
}
[TearDown]
public void TearDown()
{
TransactionScope.Dispose();
}
**//------ TESTS -------//
// CanSetAndGetUserName
// AuthorizedUserCanGetData
// UnauthorizedUserCannotGetData
// AuthorizedUserCanPutData
// UnauthorizedUserCannotPutData
// AuthorizedUserCanPostData
// UnauthorizedUserCannotPostData
// AuthorizedUserCanDeleteData
// UnauthorizedUserCannotDeleteData**
[Test]
public void CanGetAndSetUsername()
{
// ARRANGE
var user = _controller.getUserName();
// ACT
// ASSERT
Assert.That(user, Is.EqualTo("my-internal-username"));
}
[Test]
public void UnauthorizedUserCannotGetData()
{
var user = "Mr Unauthorized";
// Unfinished bc integration testing is super abstract, subjective, hard, time consuming and hard. All downvoters are plebs.
Assert.That(user, Is.EqualTo());
}
}
}
}
