Migrate test suites to account for testing library upgrades
fleet,kibana-cloud-security-posture (#201167)\n\nThis PR migrates test
suites that use `renderHook` from the
library\r\n`@testing-library/react-hooks` to adopt the equivalent and
replacement\r\nof `renderHook` from the export that is now available
from\r\n`@testing-library/react`. This work is required for the
planned\r\nmigration to react18.\r\n\r\n## Context\r\n\r\nIn this PR,
usages of `waitForNextUpdate` that previously could have\r\nbeen
destructured from `renderHook` are now been replaced with
`waitFor`\r\nexported from `@testing-library/react`, furthermore
`waitFor`\r\nthat would also have been destructured from the same
renderHook result\r\nis now been replaced with `waitFor` from the export
of\r\n`@testing-library/react`.\r\n\r\n***Why is `waitFor` a sufficient
enough replacement for\r\n`waitForNextUpdate`, and better for testing
values subject to async\r\ncomputations?***\r\n\r\nWaitFor will retry
the provided callback if an error is returned, till\r\nthe configured
timeout elapses. By default the retry interval is `50ms`\r\nwith a
timeout value of `1000ms` that\r\neffectively translates to at least 20
retries for assertions placed\r\nwithin waitFor.
See\r\nhttps://testing-library.com/docs/dom-testing-library/api-async/#waitfor\r\nfor
more information.\r\nThis however means that for person's writing tests,
said person has to\r\nbe explicit about expectations that describe the
internal state of the\r\nhook being tested.\r\nThis implies checking for
instance when a react query hook is being\r\nrendered, there's an
assertion that said hook isn't loading anymore.\r\n\r\nIn this PR you'd
notice that this pattern has been adopted, with most\r\nexisting
assertions following an invocation of `waitForNextUpdate`
being\r\nplaced within a `waitFor`\r\ninvocation. In some cases the
replacement is simply a `waitFor(() => new\r\nPromise((resolve) =>
resolve(null)))` (many thanks to @kapral18, for\r\npoint out exactly why
this works),\r\nwhere this suffices the assertions that follow aren't
placed within a\r\nwaitFor so this PR doesn't get larger than it needs
to be.\r\n\r\nIt's also worth pointing out this PR might also contain
changes to test\r\nand application code to improve said existing
test.\r\n\r\n### What to do next?\r\n1. Review the changes in this
PR.\r\n2. If you think the changes are correct, approve the
PR.\r\n\r\n## Any questions?\r\nIf you have any questions or need help
