[Feature]: Add jest and write tests for scripts/extractSlideData.js

[AhsanAyaz]

Right now, we don't have any tests in the repository. And we have the scripts/extractSlideData.js file which can have unit tests. The task is to write these unit tests.

I would like to work on this

Please assign the task to me.

Hey @anttijankeri , Sorry but I already started working on this part and created the test functions for extractTitle. Is it possible for you work on some other issue?

[Rachit1313]

Hi @AhsanAyaz , Could you please review and let me know if any changes are required?

[AhsanAyaz]

@Rachit1313 I've merged your PR but even though we use jest, the test command doesn't include jest. It still runs gulp test behind the scenes. But also has an issue with the tests in windows:

@anttijankeri maybe you can have a look?

@Rachit1313 I've merged your PR but even though we use jest, the test command doesn't include jest. It still runs gulp test behind the scenes. But also has an issue with the tests in windows:

As I can confirm in the screenshot provided, The difference here is that the function returned the path with // i.e windows formatting for a path whereas I created the functions in a macOS.
This can be fixed by adding another statement of checking equal to mac version or windows output.

@anttijankeri hope this helps!
Let me know if you want me to make the changes.

For the gulp test.
That's because test script was already setup for gulp in the package.json. I wasn't sure if you wanted me to update it or not.

Let me know if you want me to change that.

Ive fixed the problems from earlier. The windows thing may or may not work, cant test it atm.
