Tests to write

High level

Users see journeys, so test that each journey and the most common multi-step journeys render without error.

• Amount
• Donate tab
• Email
• Share
• Register, Share
• Amount, Donate Tab

@xavier Could you add in / correct the list of journeys? Thanks!

Components

Rendering

Do components render with the expected values / elements? Components might need a customRender to be tested https://testing-library.com/docs/react-testing-library/setup#custom-render

Behaviours

Do the messages update when the amount changes? do errors get displayed.

Integration

Does the GraphQL mutation get sent when it should?

Can the code handle the messages it will get?

i18n

Are there missing translations?

• Replace the static use of "en" in package.json jest config with moduleNameMapper described here https://jestjs.io/docs/webpack#mocking-css-modules
• [ ]

I'm starting in on these in the branch https://github.com/fixthestatusquo/proca/tree/feature/unit-tests

Any update? do you need help?

[aaronelliotross]

Ah I totally forgot about this since vacation! If you have time - go for it.

[tttp]

are they still to take from the branch or can we just keep the list? (the branch is "a bit" behind ;)
