Multi tool use

I am using jest to test my reactjs application. It works fine but jest doesn't give me a good report about test case results. The output of jest shows each test suite followed by its output. I have more than 50 test suites and it is hard for me to scroll up to check each failed test cases. Is there a brief jest report which printing a brief summary about the whole test cases?
below is my jest.conf file:

jest

jest

jest

jest

jest.conf

{
"testRegex": "/tests/.*\.test\.jsx?$",
"testEnvironment": "node",
"roots": ["./src"],
"coverageReporters": ["text-summary", "html"]
}

You can run jest with the --coverage flag.

--coverage

If you want something different than the default reporters, you have to set them in your jest config file.

jest.json

{
"coverageReporters": ["text-summary", "html"]
}


text-summary gives you a short summary beneath all tests that tells you how many suites/tests are successful/failed.

text-summary

html gives you a some html pages that you can browse through to see exactly what got tested.

html

CLI

$ ./node_modules/.bin/jest --config ./path/to/jest.json --coverage

$ ./node_modules/.bin/jest --config ./path/to/jest.json --coverage

You might want to adjust which files are covered etc.
See all coverage options in the jest docs.

roots

collectCoverageFrom

rootDir

There is also a JEST HTML Reporter module which you might find useful.
It's configurable to specify what level of detail you want to show in the test report for failures
