Jest summarizing reporter

Custom reporter for Jest that only prints the summary of the test run. With diffs option, also prints the default error messages aka diffs before the summary.

Personally I think this behaviour should not require a custom reporter, and the level of similarity between this and the default output should be proof enough.

Tested only on my windows machine with a simple pet project.

If you have any questions or suggestions contact me by e-mail.

It came to my attention (a little too late) that at least 3 packages with same functionality already exist npm search results for jest summary reporters
