Questions

The instructions for sprint 1 say that the npm install should be run within the sprint 1 folder but when I attempt to use the Testing tab on vscode I am unable to run the tests from within and the output indicates the tests fail to run as it seems to be looking in the root folder for the node module for jest. I was able to run the tests using npm test however the testing functionality afforded by vscode was diminished by that. Could there be a better way of doing this?

I enclose a screenshot to demonstrate the error returned pertinent to the question I asked when initially opening this PR

Have you installed Jest first? To install Jest, in a terminal, run npm install in the Sprint-1 folder. npm will look for package.json and then install all dependencies specified in package.json.

Only after that you can run Jest test.

Changes look good.

I ran npm install in the sprint 1 folder as per instructions and have no issue using npm test via terminal, my question relates to running the tests via the testing tab in vscode and the respective functionality in the test files to run an individual test

It's not a hinderance, just wondering why its behaving this way and if there's a work around as I would like to be able to leverage the in file single test run functionality as opposed to having to run npm test each time

I don't know how to use the Jest extension in VSCode.
In terminal, we could run jest test on a particular file (in Sprint-1 folder where jest is installed locally) as

 npm test <substring that match the filename>

For examples,

• npm test fix will run all the .test.js files inside subfolder fix (because all other filenames do not have such substring).
• npm test median will run fix/median.test.js (since that's the only file with the matching substring)
