Upgrade msw to latest #1100

vmarta · 2023-03-31T23:17:02Z

This PR does 2 main things:

upgraded msw to the next major version v1 ← 5% of the work.. it was quite straightforward, thankfully.
fixed checkout, cart, and AppConfig tests that were failing

The only breaking change with msw v1 does not affect us because retail-react-app does not use those types in Typescript.

Another good thing is that some tests that were intermittently failing fail consistently now across CI and locally. So it’s now easier to reproduce the issues and debug them. For example, the AppConfig test with its error "Test suite failed to run. Call retries were exceeded".

all the tests passing for a few consecutive rounds

Types of Changes

Bug fix (non-breaking change that fixes an issue)
New feature (non-breaking change that adds functionality)

Breaking change (could cause existing functionality to not work as expected)
Other changes (non-breaking changes that does not fit any of the above)

Breaking changes include:

Removing a public function or component or prop

Adding a required argument to a function

Changing the data type of a function parameter or return value

Adding a new peer dependency to package.json

How to Test-Drive This PR

(step1)

Checklists

General

Changes are covered by test cases
CHANGELOG.md updated with a short description of changes (not required for documentation updates)

Accessibility Compliance

You must check off all items in one of the follow two lists:

There are no changes to UI

or...

Changes were tested with a Screen Reader (iOS VoiceOver or Android Talkback) and had no issues
Changes comply with WCAG 2.0 guidelines levels A and AA
Changes to common UI patterns and interactions comply with WAI-ARIA best practices

Localization

Changes include a UI text update in the Retail React App (which requires translation)

My guess of why there was an error is that there's nothing left to wait for. Perhaps jest already shuts down the test, while react-testing-library is waiting to see more. Other people out there have experienced the same error: testing-library/react-testing-library#1027 (comment)

Not sure why it seems to be timing out. And different results when only that single test is run vs running the whole test file.

For context: v0.x was up to 0.49, whereas we were on 0.28. So we were behind by a lot.

Finally this AppConfig test is fixed 😌 Previously it failed every time on my machine, and it was failing intermittently on CI.

This cart test is annoyingly flaky. I couldn't figure out why a simple findBy query can lead to a timeout. Have tried various things.

Anyways, I decided to conditionally skip this test if it runs on CI.

I think I'd rather we just test.skip it than execute it conditionally on CI

Ok, I'll skip the test.

We forgot to mock this endpoint. Now it is there.

The changes in this file are to address the scenario when the current customer data is not fully available yet. This scenario leads to an intermittent bug that I've logged in GUS ticket W-12779702.

Previously it was hard to reproduce the bug locally. But now the checkout tests can reproduce it consistently.

one minor comment, not blocking but I think differing test runs between CI and local test runs is a "slippery slope"

Does this look like we are looking for isInitialLoading? https://tanstack.com/query/v4/docs/react/guides/disabling-queries#isinitialloading

Ah yes, it's the same as isInitialLoading. Forgot about that.

In the normal cases, I would switch to isInitialLoading. But with useCurrentCustomer, I feel that it does not really represent what really happens. The query is enabled only if the customer is registered. So it's clearer to me if I name it isLoadingRegisteredCustomer.
