在MSTest运行时动态创建单元测试方法 [英] Create Unit test methods dynamically during runtime in MSTest

问题描述

MSTest中是否有SuiteBuilder的等效项?到目前为止找不到一个.

Is there an equivalent of SuiteBuilder in MSTest? couldn't find one so far.

我有一堆xml文件，每个文件都被视为映射到一种测试方法.由于其中有100多个，并且要为每个手工编写测试，所以不是一个好主意.

I have a bunch of xml files, each to be seen as mapped to a test method. As there are 100s of these and to manually write tests for each of these, is not a good idea.

因此，在nunit中，您可以实现ISuiteBuilder并使测试用例动态运行并显示为许多测试方法.

So in nunit you could implement ISuiteBuilder and have the Test cases run dynamically and show up as those many test methods.

我正在寻找一种在MSTest中执行相同操作的方法.

I am looking for a way to do the same thing in MSTest.

我已经看过DataSource属性，但是每个测试方法只能满足1个数据源xml文件/csv的要求，这迫使我编写100多个测试方法.我还想将每个xml文件分开，不要将它们全部合并为1个大文件，在这种情况下，它将变得难以维护.

I've looked at DataSource attribute, but it caters to 1 datasource xml file/csv per test method, forcing me to write 100s of test methods. I also want to keep each xml file separate and don't club them all in to 1 huge file, in which case it would become unmaintainable.

有人尝试过这个或有什么建议吗?

Has someone tried this or has any suggestions?

推荐答案

我已经做到了.这是您需要做的:

I have done this already. Here is what you would need to do:

测试:

[TestMethod]
[DeploymentItem("MyTestData")]
[DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML",
                   "|DataDirectory|\\MyTestData.xml",
                   "Test",
                    DataAccessMethod.Sequential)]
public void MyTest()
{
    string file = TestContext.DataRow[0].ToString();
    string expectedResult = TestContext.DataRow[1].ToString();
        // TODO: Test something
}

MyTestData.xml:

MyTestData.xml:

<?xml version="1.0" encoding="utf-8" ?>
<Rows>
  <Test>
    <File>test1.xml</File>
    <Result>1</Result>
  </Test>
  <Test>
    <File>test2.xml</File>
    <Result>2</Result>
  </Test>
</Rows>

test1.xml和test2.xml必须存在于MyTestData目录中.

test1.xml and test2.xml must exist in the MyTestData directory.
