Testfx: Inline DataRow is not available on TestContext.DataRow for Inline [DataTestMethod]

[josephliccini]

Description

Describe the issue you've observed
I have a test:

        [TestMethod]
        [TestCategory("VisualParity")]
        [DataTestMethod]
        [DataRow(TestScreen.Large, LocaleDirection.RTL, Ring.WorldWide)]
        public void HomeConsumer_Hero_Screenshot(int screenWidth, string direction, string ring)
        {
            SetupTest(screenWidth, direction, ring);

            // in some later code, where TestContext is passed in...
            var screenshotName = TestContext.TestName + "_" + TestContext.DataRow.ItemArray[0];
            // ...
        }

DataRow is null

@josephliccini : This is By-Design. All data driven tests based off of the new ITestDataSource contract (DataRow included) provide values via method arguments. The TestContext.DataRow values will only be filled in when a DataSource attribute is used. Here is the documentation of the design and usage.

@AbhitejJohn Thanks!! We are really enjoying the new features, especially data driven test. Will hook this up!!

[josephliccini]

Just double checking, this document is saying, if you need DataRow access, then you would have to access the entries via the parameters of the [TestMethod]. There is no way to get the parameters via the test context?

Not an issue, and I think the design is sound, just trying to make sure I understand.

Thanks!

That is correct. Testcontext would not have these filled in anymore for ITestDataSource extensions.

@AbhitejJohn , is there any other way/workaround to get the data other than from Testmethod parameters when I am using DataRow, I am asking is because my test framework is using [TestCleanup] method to generate test report via reading TestContext to get test name, status etc. And now the datarow in TestContext is null by design if using [DataRow]

can this be re-opened. it would be really helpful to get access to the test parameters via the TestContext
