To unit test a regular function (that is not suspended) that returns a Result&lt;T&gt; after a `sequence {` of logical validations (none of which are long running), do I have to use `runTest` in each test case? The result is obtained through a terminal operation on the sequence. I was not using runTest and my tests were always passing locally but failed on the CI. A colleague found a solution using runTest with an Unconfined dispatcher. I am trying to understand why this solved the issue and if it is always needed for dealing with sequence builders that yield a result.

`sequence` doesn't use any `kotlinx.coroutines` dispatchers so it shouldn't be related

do you have a <https://stackoverflow.com/help/mcve|MCVE>? you could even try it on Kotlin Playground, like this: <https://pl.kotl.in/qJP0qRYK3>

you are right <@UJQB4DJF7>! It was my bad actually. I didn't recall the solution correctly. There was no need for the unconfined dispatcher.  However, the runTest was what solved the CI issue.

 I ended up rewriting the functions as sequences were not really needed. But i still want to get a better understanding of the CI issue. I will work on getting a MCVE. Thank you!
