[SOLVED] Output total tests run by Jest into variable

Issue

I'd like to be able to programmatically get the number of tests run by the jest command and store that in a variable so I can report metrics on it.

So the output of running the Jest command looks like this

Test Suites: 29 passed, 29 total
Tests:       224 passed, 224 total
Snapshots:   0 total
Time:        287.464 s
Ran all test suites.

How can I store the 224 number (total tests ran)?

I've tried jest --listTests but that just lists the test files. The reports don't seem to contain the number of tests run, just the number and % of files, functions, and branches covered.

Solution

you can combine the output with awk. to get the total test numbers.

normal output

assign the total field to a variable, total:

bash command: total=$(/command/of/jest 2>&1 | awk '/Tests:/{print $(NF-1)}')
