NUnit CategoryName - selenium

Question

I tried for the first time using TestCase as explained here.
I normally got the category name (for debug purpose) like this:
lstCategories = (System.Collections.IList)NUnit.Framework.TestContext.CurrentContext.Test.Properties["Category"];
and then found the category name like this:
(string)lstCategories[0]
But when I use TestCase I could not get it (it is empty).
Please help.

Answer 1

Did you setup your [Test] method as in the example which you provided? There is an example of how to pass data to the test method:
private static IEnumerable<TestCaseData> AddBrowserConfs()
{
yield return new TestCaseData("chrome", "72.0", "Windows 10");
yield return new TestCaseData("internet explorer", "11.0", "Windows 10");
yield return new TestCaseData("Safari", "11.0", "macOS High Sierra");
yield return new TestCaseData("MicrosoftEdge", "18.0", "Windows 10");
}
[Test, TestCaseSource("AddBrowserConfs")]
public void DuckDuckGo_TestCaseSource_Demo(String browser, String version, String os)
{
As you can see, values from AddBrowserConfs are passed as arguments in DuckDuckGo_TestCaseSource_Demo. Does this answer your question?

Answer 2

With test cases you are not getting Category name because its not set properly. You need to set it with each test cases as below:
[Test]
[TestCase(12, 4, Category = "MyCat")]
[TestCase(10, 6, Category = "MyCat")]
public void Test2(int a, int b)
{
Assert.AreEqual(a + b, 16);
var catName = TestContext.CurrentContext.Test.Properties.Get("Category").ToString();
Console.WriteLine(catName);
}
OR if you are using TestCaseSource, add Category name as below:
[Test]
[TestCaseSource(typeof(AddCases), Category = "MyCat")]
public void Test2(int a, int b)
{
Assert.AreEqual(a + b, 16);
}
public class AddCases : IEnumerable
{
public IEnumerator GetEnumerator()
{
yield return new object[] { 8, 8 };
yield return new object[] { 10, 6 };
yield return new object[] { 12, 4 };
}
}
Hope this helps.
