I am currently trying to setup circleci for my open source project.
But if I run the CircleCi, which at first builds the project and than tests it with jest, gets stuck on the ‘jest’ command.
I don’t know why and I couldn’t find any solution yet.
Could you try running jest with the --runInBand option? --clearCache can help to rule out any caching issues as it does look like you are making use of caching.
