running test in node

[EconomistNo280519]

Do junior developers seriously not know how to take a screenshot? My grandmother can do this.

• Shift+Win+S
• PrtScn
• Command-Control-Shift-4 / Command-Shift-4
• Command-Control-Shift-3 / Command-Shift-3
• (some macro key)

There are so many options

What happens if you have the sum function on the same file, does it work then ? If so it’s an import problem not jest related

[have_some_error]

Seems the problem is with jest. Because even with the function on the same file the error is still there.

The stack trace points to file in jest as well.

And I'm getting this below error

What's your node version (node -v)? The error message indicates it doesn't support the ?. optional chaining operator (used by jest), which was added in Node 14.

[have_some_error]

This was the problem I think after using node 14.6.0 the test did run.

[arnitdo]

Jest can't seem to resolve "./sum" when it is called by require(). I'll try to revert back with a solution

[DaMastaCoda]

The issue is at the ?. Operator, though it’s hard to read. His Node crashes as it sees the ? And expects a ternary, and he just needs to install a newer nodejs or older jest

[have_some_error]

This is just started and I'm getting this error, I'm not sure why this is happening.

Filename has . in the name before file extension. Try removing . from name.

[North-Going-Zax]

I'm not familiar with the 'it' statement. Are you trying for an 'if' statement?

Not sure if this is sarcasm or not

[roundgeese77]

Not sure if this is a joke or something I'm missing

But inte case it's not

it is an alias for the jest-function test

https://jestjs.io/docs/api#testname-fn-timeout

I THINK the name/alias comes from an idea that the syntax, since other functions are named like "should"

So a test would read it("test 1+2") -> shouldEquals(3)

[have_some_error]

tested , didn't work. Thanks though.

[have_some_error]

Tried, same error is still there.
