C# NUnit TestCaseSource 传递参数

Question

我有以下生成一组测试用例的方法!

public IEnumerable<ResultsOfCallMyMethod> PrepareTestCases(param1)
{
    foreach (string entry in entries)
    {
        yield return callMyMethod(param1);
    }
}

如何将字符串类型的参数作为参数传递给我的 PrepareTestCases() 方法？

有没有办法做到以下几点:

[Test, Category("Integration"), TestCaseSource("PrepareTestCases", param1)]
public void TestRun(ResultsOfCallMyMethod testData)
{
    // do something!
}

Answer 1

我在即将发布的最新版nunit(3.2)中对此进行了修改。

https://github.com/nunit/nunit/blob/4f54fd7e86f659682e7a538dfe5abee0c33aa8b4/CHANGES.txt

• TestCaseSourceAttribute now optionally takes an array of parameters that can be passed to the source method

现在可以做这样的事情了

[Test, Category("Integration"), TestCaseSource(typeof(MyDataSources),"PrepareTestCases", new object[] {param1})]
public void TestRun(ResultsOfCallMyMethod testData)
{
// do something!
}

private class MyDataSources
{
  public IEnumerable<ResultsOfCallMyMethod> PrepareTestCases(param1)
  {
    foreach (string entry in entries)
    {
        yield return callMyMethod(param1);
    }
  }
}
