Finatra is an open-source project by Twitter that can be used to build REST APIs in Scala programming language. Finatra builds on top of Twitter’s Scala stack — twitter-server, finagle, and twitter-util.
- Finagle: It can be used to construct high performance servers.
- Twitter Server: It defines a template from which servers at Twitter are built. It uses finagle underneath.
- Twitter-Util: A bunch of idiomatic, small, general purpose tools for Scala.

Today, I encountered an issue while running tests for one of my Scala SBT projects. Each time, ran sbt test command hang. After running jvisualvm, I discovered that it is due to thread deadlock. I couldn’t figure out why deadlock is happening. Test cases worked fine when ran individually. To work through this issue, I disabled parallel execution of tests.
From command-line, you can use following command to disable parallel execution of test:
$ sbt 'set parallelExecution in Test := false' test
You can also set this setting in your build.sbt to avoid setting this setting manually.In your build.sbt , add the following line.
parallelExecution := false
