This project is written in Node, and tested with Vitest - Blazing Fast Unit Test Framework.
When npm runs vitest, all the tests are failing as seen at the end of its output to the console.
npm install
Start with the first file.
npm run test:1
The above npm command is equivalent to the following but is easier to type:
npx vitest tests/stmnts-01.test.js --globals --run --reporter verbose
as inside the package.json you see it is listed in the scripts:
"test:1": "vitest tests/stmnts-01.test.js --globals --run --reporter verbose"
Repeat tha process for all of your test files.
NOTE: As you are editing, don't forget to save the file before you try running the test or it won't be able to see the changes.
So the above example tests the first file tests/stmnts-01.test.js and outputs the results to the console.
If a test fails, vitest will identify it as failing and print one or more error messages, depending on the test expectations.
One-by-one and in order, edit each JavaScript file and follow the instructions for each coding skill. You should run the test after each completed skill and see the pass count increase. When one file passes completely, you are ready for the next file.
Start with stmnts-01.test.js and finish with stmnts-04.test
When you feel the coding skills are completed, the following command will test all files in the repo that end in test.js
npm test
Commit and push after all tests pass. GitHub will run the same tests and report pass/fail.
