Thanks for this. This is definitely the best I could find for beginners. I have been in trouble from past 2 days for import error and could not find a solution

Hmm.. I never get that error. But maybe you're not installing typescript yet? Sorry for just replying. I can't maintain the youtube for now..

Im getting ===
> mocha -r ts-node/register src/test/*.spec.ts --reporter mochawesome --reporter-options reportDir=test-results
TSError: ⨯ Unable to compile TypeScript:
src/service/orderService.ts:103:7 - error TS6133: 'discountTypeEnum' is declared but its value is never read.
====
Can anyone help me here.
Im trying to setup Mocha with typescript

[@masteryst]

Hi! That error is just because of your lint has setting if the variable, enum or something didn't used, then give error message. So, if you're not setting the discountTypeEnum, just remove it till you need to use it :).
Or you can read this, and just remove the lint config that is source of your problem.

@@masteryst Thanks for responding. But it's not working. The issue is not something with ESlint config. Can you plz suggest any other one.
Thanks in advance

@@sriharichandanamummaneni Hi! Oh my.. I am really really sorry, I don't know why but there's no notification on this comment, so I didn't know..
'discountTypeEnum' is declared but its value is never read.

Hi @sriharichandanamummaneni have you been able to make work mochawesome with Typescript? When I execute the command:
"test": "set TS_NODE_COMPILER_OPTIONS={\"module\": \"commonjs\"} && mocha --require ts-node/register ./tests/**/*.spec.ts --reporter mochawesome --reporter-options reportDir=test-results"
In the html created, I don't see TS code, only compiled JS code.
Thanks in advice.
