A jest results processor showing test files that exceed a duration threshold
$ npm install jest-duration-results-processor --save-dev
By default, the threshold duration is set to 10 seconds. Use an environment variable to override the default:
# Set the duration threshold to 1 seconds
$ export JEST_RESULTS_DURATION_THRESHOLD=1000
# Launch all test suites and report files exceededing a duration of 5 seconds
$ JEST_RESULTS_DURATION_THRESHOLD=5000 \
jest --testResultsProcessor ./node_modules/jest-duration-results-processor
{
"scripts": {
"test:duration": "JEST_RESULTS_DURATION_THRESHOLD=5000 jest --testResultsProcessor ./node_modules/jest-duration-results-processor"
},
}
