单元测试 C# [TestInitialize]

Question

我在 C# Web API 控制器上执行单元测试 - 每个控制器都需要几个参数来初始化。我目前在每个测试中都有以下代码，但它非常庞大。如何将此代码放入 [TestInitialize] 以便在每次测试之前运行？

我尝试了以下方法，但显然它超出了测试方法的范围。

[TestInitialize]
public void TestInitialize()
{
    APIContext apicon = new APIContext();
    xRepository xRep = new xRepository(apicon);
    var controller = new relevantController(cRep);
    controller.Request = new HttpRequestMessage();
    controller.Configuration = new HttpConfiguration();
    relevantFactoryModel update = new relevantFactoryModel();
}   

Answer 1

您可以将需要的变量设置为测试类的字段，然后在TestInitialize方法中进行初始化。

class Tests 
{
    // these are needed on every test
    APIContext apicon;
    XRepository xRep;
    Controller controller;
    RelevantFactoryModel update;

    [TestInitialize]
    public void TestInitialize()
    {
        apicon = new APIContext();
        xRep = new xRepository(apicon);
        controller = new relevantController(cRep);
        controller.Request = new HttpRequestMessage();
        controller.Configuration = new HttpConfiguration();
        update = new relevantFactoryModel();
    }   
}

这样可以从每个测试中访问字段
