This may be unnecessary, but avoid potential issues where fake timers are unexpectedly used and cause breakages in other tests.
Previously, `waitFor` would timeout when `jest.useFakeTimers('modern')`
was enabled. The 'modern' version is now the default in Jest 27.
The Jest preset from `@testing-library/react-native` provides a
workaround for a larger issue in React Native and Jest that mutates the
global `Promise` object. https://git.io/JSDZI
Enabling fake timers can have negative consequences with `waitFor`, e.g. causing unexpected timeouts. Enabling it globally is far-reaching and this should likely be enabled within individual tests as needed.
The latter is considered the successor to the former. We seemingly do not depend on anything explicitly provided by `jest-jasmine2` and should likely move on from it.
Improves speed of test environment setup and fixes a timeout issue when
combining `waitFor` and `jest.useFakeTimers('modern')`. It is not yet
exactly pinpointed as to _why_ this fixes the timeout issue. It appears
to related to `setImmediate` and `setTimeout`.
This may be unnecessary if `testEnvironment: 'node'` is retained. However, most tests are currently broken due to missing DOM APIs.

[Type] Automated Testing
Now that `testEnvironment: 'node'` is utilized for the testing environment, we must mirror the app runtime and polyfill the necessary DOM APIs used in the source. The Enzyme configuration removed conflicts with the switch from `testEnvironment: 'jsdom'` to `testEnvironment: 'node'`. Enzyme depends upon `react-dom`, which introduces far more dependencies upon DOM APIs. Currently, all Enzyme-related tests fail and need to be replaced with `@testing-library/react-native`.
Importing `react-dom` introduces additional dependencies upon the DOM API and is incompatible with `testEnvironment: 'node'`. The `act` utility is available from `@testing-library/react-native`.
This may not be necessary, but may help avoid unexpected issues from lingering fake timers, e.g. timeout errors while using `waitFor`.
The Jest preset from `@testing-library/react-native` that fixed support for "modern" timers by modifying the polyfilled the global `Promise` resulted in new failures from within React Native itself. Specifically, core React Native components rely upon `.done` from the `promise` package. `.done` is a non-standard method that does not exist on the global `Promise` used by `@testing-library/react-native`'s preset.
This previously passing test now fails after upgrading `@testing-library/react-native` due to changes in the library. Setting `pointerEvent` to "box-none" or "none" currently erroneously prevents triggering other events unrelated to pressing on the element, e.g. `onTouch*`, `onLayout`. https://git.io/JSHZt
The Jest team create jest-circus as the predecessor for jest-jasmine2. The former does not support the `done` callback with async/await, and would appear to have no plans to do so. It would likely benefit us to refactor the one current test using `done` away from it, and embrace `jest-circus` to maintain alignment with Jest core.

While it may not appear this way, I did my best to minimize the changes required to resolve the native test timeouts. Unfortunately, after the core change of switching from jsdom to node, I continued to run into various issues that required further changes. I suppose this is not too surprising given the environment switch is a fairly foundational change to the testing environment.
Regardless, apologies for the large PR. Thanks in advance for reviewing! 🙇🏻

I was unable to determine what impact this line has. It would appear to have no impact on the test outcome.

I don't know about the native code, but in the case of web codebase, we migrated to importing store references when using selectors and action to ensure that stores are initialized. In practice, it means we no longer need to explicitly import packages to ensure stores are ready to work.

Ah, interesting. So, you mean to say that this line ensured that the relevant store is imported and thus registered? I am unable to picture what the alternative approach or "explicitly import packages to ensure stores are ready to work" would entail.

I better share an example to better illustrate what I mean.
Here you need to ensure that the store in use is already registered:
(in this case, this component won't work correctly until the
@wordpress/edit-post package is loaded).
In contrast by using:
and
You automatically ensure that the store is registered before it is used in code.

Ah! I believe understand now. I interpret this to relate to #27088. I have begun implementing that pattern in other work as well.
I suppose, at one point, this test leveraged the referenced import '../../..'; to ensure the store was registered. It would appear that is no longer necessary, likely due to changes in child components to instead import store references.

If desired, we could revert the upgrade of @testing-library/react-native to reinstate this test and other related, skipped tests. Enabling the skipped tests are blocked by callstack/react-native-testing-library#897.

Rather than enabling fake timers globally, individual tests should manage this themselves. This helps avoid unexpected behaviors and outcomes when authoring new tests.

This is what we have in web unit tests as well. We use the default timers shipped with Jest, and only for backward compatibility in existing tests, we enable older fake timers case by case.
There was a problem hiding this comment.
That makes sense. Unfortunately, due to a known issue, we are unable to leverage the default, "modern" Jest timers with React Native currently. Leveraging @testing-library/react-native's provided preset workaround breaks others aspects of our existing tests. Hopefully we can embrace the default timers soon.

It takes a bit of time for all the tools to upgrade to the latest APIs. I'm getting used to it.

It'd be great to have another check from someone more familiar with the test configuration and how the individual tests should work. I reviewed the overall direction which in my opinion is very much aligned with the web now 👍🏻
There are some errors reported on the CI that should be worked on as a follow-up. They don't seem to break the tests but they might impact the reliability in the long run. Examples from https://github.com/WordPress/gutenberg/runs/4744173096?check_suite_focus=true:
We use @wordpress/jest-console with web unit tests:
It fails the tests if there is a warning or error printed on the JS console. It isn't strictly necessary but it's a way to catch those violations that might be a root of some subtle bugs.
@gziolo thank you so much for taking the time review. Much appreciated! 🙇🏻 I am happy to hear the changes better align native and web. I requested @fluiddot review this work, so I am sure he will be provide his perspective as well when he has time. I will await his feedback before merging.
Thank you for noting this. We are aware of most of these, but have yet to address them since they do not caused explicit failures, as you mentioned. However, I definitely would like to get them addressed in a follow-up PR.
This is great! I was unaware of
This sounds great! I agree moving the native unit test environment away from |

Amazing work @dcalhoun 🏅 , I've performed a review and posted some minor comments, none of them should be considered as blockers but as nice to have. Let me know if you'd like to skip them and I'll approve the PR.
I saw that there's the chance to remove the shallow function, as stated in one of the comments (reference), which is the only part that could be highlighted from my comments, yet it shouldn't block the PR.

Improve test clarity with explicit expect assertions. Co-authored-by: Carlos Garcia <[email protected]>
The switch away from Enzyme reduced this abstraction to a single line, so it provides less value now.
This increases consistency amongst the tests, as most already include this assertion.
This selection better aligns with the test description.

The test environment now imports the globals setup file used by the app runtime. That file includes a `matchMedia` global definition as well.
Improve test clarity with explicit expect assertions.
Shallow rendering components is generally considered a non-optimal approach to testing React components by the React community. This replaces `shallow` with `render` to further test integration of the subject components.
The `React` import was utilized by the now removed `shallow` render implementation.
Jest runs each test file independently, so top-level code will not impact other test files. Since the `(before|after)All` usage in code changed is all top-level, and not within a `describe`, it is superfluous.

…iate (#37715) * Upgrade to @testing-library/[email protected] * Clean up fake timer usage after tests This may be unnecessary, but avoid potential issues where fake timers are unexpectedly used and cause breakages in other tests. * Enable combination of modern fake timers and waitFor Previously, `waitFor` would timeout when `jest.useFakeTimers('modern')` was enabled. The 'modern' version is now the default in Jest 27. The Jest preset from `@testing-library/react-native` provides a workaround for a larger issue in React Native and Jest that mutates the global `Promise` object. https://git.io/JSDZI * Remove global enabling of fake timers Enabling fake timers can have negative consequences with `waitFor`, e.g. causing unexpected timeouts. Enabling it globally is far-reaching and this should likely be enabled within individual tests as needed. * Replace jest-jasmine2 with jest-circus The latter is considered the successor to the former. We seemingly do not depend on anything explicitly provided by `jest-jasmine2` and should likely move on from it. * Switch testing environment from jsdom to node Improves speed of test environment setup and fixes a timeout issue when combining `waitFor` and `jest.useFakeTimers('modern')`. It is not yet exactly pinpointed as to _why_ this fixes the timeout issue. It appears to related to `setImmediate` and `setTimeout`. * Remove setImmediate global for testing environment This may be unnecessary if `testEnvironment: 'node'` is retained. However, most tests are currently broken due to missing DOM APIs. * Polyfill required DOM APIs for testing environment Now that `testEnvironment: 'node'` is utilized for the testing environment, we must mirror the app runtime and polyfill the necessary DOM APIs used in the source. The Enzyme configuration removed conflicts with the switch from `testEnvironment: 'jsdom'` to `testEnvironment: 'node'`. Enzyme depends upon `react-dom`, which introduces far more dependencies upon DOM APIs. Currently, all Enzyme-related tests fail and need to be replaced with `@testing-library/react-native`. * Avoid import of react-dom within native file Importing `react-dom` introduces additional dependencies upon the DOM API and is incompatible with `testEnvironment: 'node'`. The `act` utility is available from `@testing-library/react-native`. * Explicitly toggle fake timers in tests This may not be necessary, but may help avoid unexpected issues from lingering fake timers, e.g. timeout errors while using `waitFor`. * Reinstate legacy Jest timers The Jest preset from `@testing-library/react-native` that fixed support for "modern" timers by modifying the polyfilled the global `Promise` resulted in new failures from within React Native itself. Specifically, core React Native components rely upon `.done` from the `promise` package. `.done` is a non-standard method that does not exist on the global `Promise` used by `@testing-library/react-native`'s preset. * Disable erroneously failing test This previously passing test now fails after upgrading `@testing-library/react-native` due to changes in the library. Setting `pointerEvent` to "box-none" or "none" currently erroneously prevents triggering other events unrelated to pressing on the element, e.g. `onTouch*`, `onLayout`. https://git.io/JSHZt * Reinstate jest-jasmine2 to support done callback The Jest team create jest-circus as the predecessor for jest-jasmine2. The former does not support the `done` callback with async/await, and would appear to have no plans to do so. It would likely benefit us to refactor the one current test using `done` away from it, and embrace `jest-circus` to maintain alignment with Jest core. * Refactor native unit tests away from done callback The Jest team created `jest-circus` as the predecessor for `jest-jasmine2`. The former does not support the `done` callback with async/await, and would appear to have no plans to do so. In order to embrace `jest-circus` and maintain alignment with Jest core, the one test using `done` was refactored to avoid it - https://git.io/JSHWU - https://git.io/JSHWk * Remove Enzyme from Editor tests * Remove Enzyme from Paragraph tests * Remove Enzyme from BlockMover tests * Remove Enzyme from BlockEdit test * Remove Enzyme from LinksUI test * Remove Enzyme from ListEdit tests * Remove Enzyme from Platform tests * Remove Enzyme from BlockTypesTab tests * Remove Enzyme from HTMLTextInput tests * Remove Enzyme from ReusableBlockTab tests * Remove Enzyme from MediaUpload tests * Remove Enzyme from BlockMediaUpdateProgress tests * Remove Enzyme from MediaUploadProgress tests * Fix ReferencEerror in Inserter test Usage of `react-test-renderer` caused the following error.

That file includes a `matchMedia` global definition as well. * Add assertions to LinkSettings tests Improve test clarity with explicit expect assertions. * Removed shallow renderer usage in tests Shallow rendering components is generally considered a non-optimal approach to testing React components by the React community. This replaces `shallow` with `render` to further test integration of the subject components. * Remove unused import The `React` import was utilized by the now removed `shallow` render implementation. * Remove unnecessary top-level beforeAll usage Jest runs each test file independently, so top-level code will not impact other test files. Since the `(before|after)All` usage in code changed is all top-level, and not within a `describe`, it is superfluous. Co-authored-by: Carlos Garcia <[email protected]> * Fix erroneous react-dom usage in native tests (#37921) * Reinstate react-platform.native.js file This file was removed in the following commit, as it was no longer strictly necessary. b7b62d2#diff-f02069349f238fb47a268bb7fcc03c9768331db18ead0e28d8ecad7bbc05037c However, the removal led to Jest loading the DOM-specific version of the file when mocking Gutenberg modules that depended upon `react-platform.js`. Jest would seemingly load `react-dom` when attempting to auto-mock a module, e.g. `jest.mock( '@wordpress/data/src/components/use-select' );`. The loading of `react-dom` resulted in the following error: ``` TypeError: Cannot use 'in' operator to search for 'WebkitAnimation' in undefined at getVendorPrefixedEventName (node_modules/react-dom/cjs/react-dom.development.js:5011:58) at node_modules/react-dom/cjs/react-dom.development.js:5019:21 at Object.<anonymous> (node_modules/react-dom/cjs/react-dom.development.js:26261:5) at Object.<anonymous> (node_modules/react-dom/index.js:37:20) ``` Reinstating `react-platform.native.js` addresses this issue by ensuring that Jest does not encounter an import of `react-dom`. * Fix false-positive ReactNativeEditor test This test failed when run in isolation. It would appear it was dependent upon the `jest.mock('../setup')` found in sibling tests. After defining a mock for this specific test, it was discovered that the assertion did not await the asynchronous query found within the test. The assertion resulted in a false-positive as the returned query `Promise` technically matches `toBeDefined`. `async`/`await` was added to ensure the test assertion awaits the query result, as well as fixes the following related log warning. ``` A worker process has failed to exit gracefully and has been force exited. This is likely caused by tests leaking due to improper teardown. Try running with --detectOpenHandles to find leaks. Active timers can also cause this, ensure that .unref() was called on them. ``` * [RNMobile] Fix `act` warnings that might be triggered after test finishes (#38052) * Fix act warnings after test finishes This is a workaround for addressing the act warnings that might caused by store updates executed after the test finishes. * Update comment of setImmediate workaround Co-authored-by: David Calhoun <[email protected]> * Unmount editor when test finish * Update initialize editor helper The function is now synchronous as we don't have to wait for any element. * Update tests that use initialize editor * Fix act warnings from store resolvers with fake timers (#38077) * Leverage fake timers to resolve store resolvers During editor initialization, asynchronous store resolvers rely upon `setTimeout` to run at the end of the current JavaScript block execution. In order to prevent "act" warnings triggered by updates to the React tree, we leverage fake timers to manually tick and await the resolution of the current block execution before proceeding. * Update RichText test `initializeEditor` usage The refactor of `initializeEditor` to leverage fake timers means this test no longer needs to `await` asynchronous work or manuall `unmount` its subject component. * Refactor usage of `initializeEditor` in tests Now that `initializeEditor` leverages fake timers to resolve asynchronous store resolvers, the tests no longer need to await a resolution of `initializeEditor`. * Fix `act` warnings in Image edit test Retrieving text from the clipboard is an asynchronous action. The component updated React state once the clipboard resolved. This resulted in a state update triggering an `act` warning. Because there is no visible change to the rendered output, e.g. updated text or UI, we must await the resolution of the clipboard promise itself.

Description
This fixes native unit test timeouts. When using fake timers, the use of
jsdomappears to break usage ofsetImmediate, specifically within@testing-library/react-native's built-incleanuputility.Most example React Native projects — e.g. React Native,
@testing-library/react-native(Jest 27 changed the default) — utilize Jest'stestEnvironment: 'node'. The native tests within the Gutenberg project currently usetestEnivronment: 'jsdom', presumably because aspects of the source rely upon the DOM, e.g.hpqrequires a globaldocument.These changes update the testing environment from
jsdomtonodeand instead relies upon the DOM globals setup used for the app runtime. This resolves the aforementionedsetImmediateissue and more closely aligns the project's testing environment with the app runtime and React Native community practices.Key Changes:
@testing-library/[email protected].jsdomwithnodetest environment to avoid Combining jsdom testEnvironment and fake timers results in timeout errors callstack/react-native-testing-library#896.jest-jasmine2with successorjest-circusto remain aligned with Jest core.enzymeto avoid dependency onreact-dom.How has this been tested?
