rework unit tests (mocking the fetch()) #2183

Closed ftoromanoff closed 5 months ago

ftoromanoff commented 1 year ago

This PR propose a rewrite of the unit tests:

minor corrections in tests
mocking of the 'fetch()' function to have unit tests to run independent from network
- to do that the files that should have been fetch have been added localy.
- we use sinon to mock itowns.Fetcher
add a file test for testing Fetcher.js

Modifications:

add 'sinon' library to do the mocking
all tests
- add all test files in local folder test/data/unitTest
- change global url to local ones
add fetcher.js to test Fetcher.js
- add library xml dom for xml fetcher
