Question

我需要模拟数据库连接，然后调用一个方法以返回值。

我创建了最小起订量数据，但不确定如何模拟数据库连接。

layoutData

在下面的控制器类中是所需的参数

<l:VerticalLayout width="100%" >
    <HBox>
        <IconTabBar>
            <items>
                <IconTabFilter text="abc" class="Tabheader">
                </IconTabFilter>
                <IconTabFilter text="fdvvvfv"></IconTabFilter>
                <IconTabFilter text="vdfvvdvvv"></IconTabFilter>
                <IconTabFilter text="Avfdsd"></IconTabFilter>
            </items>
            <layoutData>
                <FlexItemData growFactor="2" />
            </layoutData>
        </IconTabBar>
        <Button text="Button" class="sapUiSmallMarginTop sapUiTinyMarginBegin" />
    </HBox>
</l:VerticalLayout>

需要从列表而不是数据库中获取数据

private void SetupUserRepository()
{
    var firstname = "FirstName1";
    var _lastName = "LastName1";
    var _userName = "FirstName1.LastName1@warburgpincus.com";
    var _email = "FirstName1.LastName1@warburgpincus.com";
    var User = new User { FirstName = firstname, LastName = _lastName, Username = _userName,Email = _email};
   var mockUserRepository = new Mock<IUserRepository>();
       // mockUserRepository.Setup(m => m.GetOne(It.IsAny<string>(), It.IsAny<CancellationToken>())).ReturnsAsync((string section, CancellationToken token) => moqData.contentControls.FirstOrDefault(a => a.InternalControlName == section));
   // mockUserRepository.Setup(m => m.GetOne(It.IsAny<string>(), It.IsAny<CancellationToken>()));
    //var x = moqData.userDetails.First(a => a.Username == _userName);
    mockUserRepository.Setup(m => m.GetOne(It.IsAny<string>(), It.IsAny<CancellationToken>())).ReturnsAsync(moqData.userDetails.First(a => a.Username == _userName));
    UserRepository test = new UserRepository(mockUserRepository.Object,null,null);
    var result = test.GetOne(_userName, It.IsAny<CancellationToken>());
    ///var repo = new UserRepository(mockUserRepository.Object,null,null);
    //var actual = await repo.GetOne(_userName, It.IsAny<CancellationToken>());
    Assert.Same(User, result);
}

此行由于期望dbcontext而引发错误。

您不应该使用UserRepository的真实实现。而是使用您的IUserRepository模拟：

var mockUserRepository = new Mock<IUserRepository>();
...
var result = mockUserRepository.Object.GetOne(_userName, It.IsAny<CancellationToken>());
