Merge Unit Test Coverage Data​

To get the coverage report, first make sure all the requirements are met and then run Keploy test as usual with your application command:

keploy test -c "your_application_command"

After successful execution of this command, A coverage report would be generated inside the test-run folder of keploy/reports.

Usage​

Update package file​

Update the package.json file that runs the application:

  "scripts": {
    //other scripts
    "test": "jest --coverage --collectCoverageFrom='src/**/*.{js,jsx}'",
    "coverage:merge": "mkdir -p ./coverage && nyc merge ./coverage .nyc_output/out.json",
    "coverage:report": "nyc report --reporter=lcov --reporter=text",
    //other scripts
  }

In test script, --coverage flag would trigger the report generation for jest. For report generation in other testing frameworks like mocha, intern, tap, refer https://istanbul.js.org/docs/tutorials/

To generate coverage report for your unit tests, Run:

npm test

To merge coverage data of unit tests with keploy tests, Run:

npm run coverage:merge

To get coverage related information for merged coverage data, Run:

npm run coverage:report
