单元测试C#[TestInitialize] [英] Unit Test C# [TestInitialize]

问题描述

我正在C#Web API控制器上执行单元测试-每个测试都需要几个参数进行初始化.目前，我在每个测试中都有以下代码，但它非常庞大.如何将这段代码放入[TestInitialize]中，使其在每次测试之前运行?

I am performing Unit Tests on C# Web API controllers - and each one requires several parameters to initialize. I have the following code in each test at the moment but it's very bulky. How can I put this code into the [TestInitialize] so that it runs before each test?

我尝试了以下方法，但显然它超出了测试方法的范围.

I have tried the following but obviously it exists out of scope for the testmethods.

[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();
}   

推荐答案

您可以将所需的变量设置为测试类的字段，然后在TestInitialize方法中对其进行初始化.

You can set the variables that you need as fields of the test class and then initialize them in the TestInitialize method.

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();
    }   
}

通过这种方式，每个测试都可以访问字段

This way the fields can be accessed from every test
