Testing

Image cards

• you can see the image cards working on this page under the sections "Featured", "Meet the prime minister", "History", etc. You can also see them on the "Related people" section of this page.

Topic list / document list

• Tracking was already added for this component in Add ga4 link tracking to topic lists #3302 but I have modified it slightly to reduce some duplication now that it is also used in the organisation pages. An example of this component is the 'Corporate information' section of this page or the 'High profile groups within MOD' heading on this page.

See all latest documents / Get emails link

• You can see the tracking for those on this page http://127.0.0.1:3070/government/organisations/attorney-generals-office or http://127.0.0.1:3070/government/organisations/prime-ministers-office-10-downing-street

Email contact links

• Look at the email links under "Contact AGO" on this page http://127.0.0.1:3070/government/organisations/attorney-generals-office or http://127.0.0.1:3070/government/organisations/prime-ministers-office-10-downing-street

I added data-people-id for testing purposes, as these elements had no distinguishable CSS selector.

Seems good, couple of probably very minor comments. If possible can you merge some of the commits that add tests with the code that they relate to? Thanks

[AshGDS]

Thanks @andysellick - should be ready for review again, and i've squashed down the commits.

[AshGDS]

@andysellick OK now it should be ready - had to add another commit as I realised I've been using lang: :en instead of locale: :en (I also did this by mistake in two other recent tracking PRs, so will fix those when I can)

Looks good 👍 remember to squash your extra commits 👍
