is there any way to change the adapter to make "datarow" level in parallel?

Description

I am trying to change the strategy of the original MSTest_Adapter to realize the parallel executing
on "DataRow" level in one method. I am asking is there any previous experience or trials on this topic?

I am happy to know you are interested in contributing.
Parallelizing the execution of data driven tests is an interesting challenge.
The data can be static or dynamic or even coming from external sources.
Also, there are the semantics of the setup and teardown methods to consider.
Let me know your thoughts. Accordingly we can publish an RFC and take it from there.

Do let us know if you need any brainstorming on this topic to help with this contribution. Thanks again for your interest.

Note, some of the semantic challenges @pvlakshm noted are described in #385 and #386.

This behavior is enabled by default on version 2.2.7+.

This behavior is enabled by default on version 2.2.7+.

@Haplois @nohwnd: Well... it’s a good feature, but the change of the default behaviour seems to be mentioned absolutely nowhere (also not in #910).
Shouldn't this be at least be mentioned in the release notes? I can imagine that this causes issues with some tests (whose [DataRow]'s are not thread-safe) and this specific issue is not the first place where i would expect such a change to be mentioned.

Also: Is there a way to revert this change without annotating the method as [DoNotParallize]? There are cases where it is fine to parallize a method in general, just not its [DataRow]'s. Also having parallized [DataRow]'s is very annoying during the debugging of tests.

Yes, please refer to this comment.

We are not seeing parallel execution at the data row level, using version 2.2.10.
Given the importance of this feature, it would be extremely helpful to document it (with setup), perhaps in the blog article.
