Console.log statements output nothing at all in Jest

Question

You can run both options together like this --watch --verbose false if you want to also be watching the files and see the output.

for one time runs just do --verbose false

As per comment on https://github.com/facebook/jest/issues/2441,

Try setting verbose: false (or removing it) in the jest options in package.json.

Jest suppresses the console log message by default. In order to show the console log message, set silent option to false at the command line

set --silent=false in the command line:

npm run test -- --silent=false

Check for your command line flags in package.json to see that you don't have --silent in there.

in addition to --verbose option which can cause this as mentioned, be aware that the --watch may also cause this bug.

Also be sure that your jest config does not have silent: true. In my case, I didn't realize that someone else had added that to our config.

I don't see it in the list of config options, but the command line flag is documented here.
