@inromualdo , I have update the description of this issue, would like to have you thought on this ?

[inromualdo]

@paulpascal , let's create a different ticket for each feature and link here.

Do you want to consider @aloundoye for some? He's interested.

I had a discussion with @paulpascal regarding the below two actions in the section setup test.

- Setup jest
- add main mocks

Due to a bug in stock-monitoring which generated errors when opening XFORMS for updates, he had to revert the work done for setting up the mentioned actions.

After a series of checks he realized that the bug was caused by exceljs but he had already reverted the unit tests setup.
Now I am unchecking it and then created issues for each feature and action.

I will notify you in the channel after creating the issues and @aloundoye could then choose any to work on.
