A new method has been added to the e2e webdriver for pasting text into
a field. This will be required to properly test a change to the SRP
input, which will be coming in a separate PR.
A few existing e2e tests have been updated to use this method to input
the SRP, to show that it works properly.
* Added Wait for Element Containing certain value function and made more robust Edit-Gas-Fee test
* Fix: changed wait for containing value and included extra waitforelements
* Fix: fix lint issue
The snap e2e tests introduced in #13671 were broken due to a conflict
with the changes in #13895. The latter PR changed the version name for
non-main builds so that it always includes the build type.
The Firefox webdriver has been updated to use the new `getVersion`
utility, ensuring that it always looks for the correct build filename.
* Changed registryUrl for snaps only in firefox
Fixed getPlatform to only be imported into metamask-controller in flask
Removed snaps specific testrunner script and use run-all with a cli option
* Fixed flakey tests
* Removed unneeded await
* Added delay

* Remove unnecessary delays on token details testcase
* Add helper function for check if element exists
* Move helper function to driver.js
* Improve name of function
We would like to insert TypeScript into the ESLint configuration, and
because of the way that the current config is organized, that is not
easy to do.
Most files are assumed to be files that are suited for running in a
browser context. This isn't correct, as we should expect most files to
work in a Node context instead. This is because all browser-based files
will be run through a transpiler that is able to make use of
Node-specific variables anyway.
There are a couple of important ways we can categories files which our
ESLint config should be capable of handling well:
* Is the file a script or a module? In other words, does the file run
procedurally or is the file intended to be brought into an existing
file?
* If the file is a module, does it use the CommonJS syntax (`require()`)
or does it use the ES syntax (`import`/`export`)?
When we introduce TypeScript, this set of questions will become:
* Is the file a script or a module?
* If the file is a module, is it a JavaScript module or a TypeScript
module?
* If the file is a JavaScript module, does it use the CommonJS syntax
(`require()`) or does it use the ES syntax (`import`/`export`)?
To represent these divisions, this commit removes global rules — so now
all of the rules are kept in `overrides` for explicitness — and sets up
rules for CommonJS- and ES-module-compatible files that intentionally do
not overlap with each other. This way TypeScript (which has its own set
of rules independent from JavaScript and therefore shouldn't overlap
with the other rules either) can be easily added later.
Finally, this commit splits up the ESLint config into separate files and
adds documentation to each section. This way sets of rules which are
connected to a particular plugin (`jsdoc`, `@babel`, etc.) can be easily
understood instead of being obscured.
This is a pure refactor that extracts the SRP input from the
`CreateNewVault` component. This is intended to make future changes to
the SRP input easier, and to reduce duplication between the old and new
onboarding flows.
Extensive unit tests have been added for the new SRP input component.
A new test library was added (`@testing-library/user-event`) for
simulating user events with components rendered using the
`@testing-library` library.
A new helper method has been added (`renderWithLocalization`) for
rendering components using `@testing-library` with just our
localization contexts added as a wrapper. The localization contexts
were already added by the `renderWithProviders` helper function, but
there is no need for a Redux provider in these unit tests.

The form used for creating a vault on the "Import" page of onboarding
and on the "Restore vault" page is nearly identical, yet the
implementation is totally separate. It has now been extracted to a
separate component, consolidating the two implementations.
There is a "terms of use" checkbox on the import page that isn't on the
restore vault page, so that part has been made optional. The "submit"
button text differs between the two uses as well, so that is
customizable.
There are slight styling differences between the old and new versions
of this form. The fonts and spacing are all using our new standard
design system guidelines, and we're using our standard checkbox now as
well. The spacing and font sizes were chosen somewhat arbitrarily by me
to resemble the old styles, so please feel free to suggest changes if
you think they can be improved upon.
There are some slight copy changes to the "Restore vault" page as well;
the placeholder text and the label for the "Secret Recovery Phrase"
field now matches the "Import" page copy.
ESLint rules have been added to enforce our JSDoc conventions. These
rules were introduced by updating `@metamask/eslint-config` to v9.
Some of the rules have been disabled because the effort to fix all lint
errors was too high. It might be easiest to enable these rules one
directory at a time, or one rule at a time.
Most of the changes in this PR were a result of running
`yarn lint:fix`. There were a handful of manual changes that seemed
obvious and simple to make. Anything beyond that and the rule was left
disabled.
The 4Byte API can sometimes fail during e2e tests with a 502 error.
Ideally we would avoid calling it at all during e2e tests, but in the
meantime we shouldn't treat this as a reason to fail the e2e test.
We have multiple fallbacks for 4Byte, it isn't relied upon by any
tests.

# Permission System 2.0
## Background
This PR migrates the extension permission system to [the new `PermissionController`](https://github.com/MetaMask/snaps-skunkworks/tree/main/packages/controllers/src/permissions).
The original permission system, based on [`rpc-cap`](https://github.com/MetaMask/rpc-cap), introduced [`ZCAP-LD`](https://w3c-ccg.github.io/zcap-ld/)-like permissions to our JSON-RPC stack.
We used it to [implement](https://github.com/MetaMask/metamask-extension/pull/7004) what we called "LoginPerSite" in [version 7.7.0](https://github.com/MetaMask/metamask-extension/releases/tag/v7.7.0) of the extension, which enabled the user to choose which accounts, if any, should be exposed to each dapp.
While that was a worthwhile feature in and of itself, we wanted a permission _system_ in order to enable everything we are going to with Snaps.
Unfortunately, the original permission system was difficult to use, and necessitated the creation of the original `PermissionsController` (note the "s"), which was more or less a wrapper for `rpc-cap`.
With this PR, we shake off the yoke of the original permission system, in favor of the modular, self-contained, ergonomic, and more mature permission system 2.0.
Note that [the `PermissionController` readme](https://github.com/MetaMask/snaps-skunkworks/tree/main/packages/controllers/src/permissions/README.md) explains how the new permission system works.
The `PermissionController` and `SubjectMetadataController` are currently shipped via `@metamask/snap-controllers`. This is a temporary state of affairs, and we'll move them to `@metamask/controllers` once they've landed in prod.
## Changes in Detail
First, the changes in this PR are not as big as they seem. Roughly half of the additions in this PR are fixtures in the test for the new migration (number 68), and a significant portion of the remaining ~2500 lines are due to find-and-replace changes in other test fixtures and UI files.
- The extension `PermissionsController` has been deleted, and completely replaced with the new `PermissionController` from [`@metamask/snap-controllers`](https://www.npmjs.com/package/@metamask/snap-controllers).
- The original `PermissionsController` "domain metadata" functionality is now managed by the new `SubjectMetadataController`, also from [`@metamask/snap-controllers`](https://www.npmjs.com/package/@metamask/snap-controllers).
- The permission activity and history log controller has been renamed `PermissionLogController` and has its own top-level state key, but is otherwise functionally equivalent to the existing implementation.
- Migration number 68 has been added to account for the new state changes.
- The tests in `app/scripts/controllers/permissions` have been migrated from `mocha` to `jest`.
Reviewers should focus their attention on the following files:
- `app/scripts/`
- `metamask-controller.js`
- This is where most of the integration work for the new `PermissionController` occurs.
Some functions that were internal to the original controller were moved here.
- `controllers/permissions/`
- `selectors.js`
- These selectors are for `ControllerMessenger` selector subscriptions. The actual subscriptions occur in `metamask-controller.js`. See the `ControllerMessenger` implementation for details.
- `specifications.js`
- The caveat and permission specifications are required by the new `PermissionController`, and are used to specify the `eth_accounts` permission and its JSON-RPC method implementation.
See the `PermissionController` readme for details.
- `migrations/068.js`
- The new state should be cross-referenced with the controllers that manage it.
The accompanying tests should also be thoroughly reviewed.
Some files may appear new but have just moved and/or been renamed:
- `app/scripts/lib/rpc-method-middleware/handlers/request-accounts.js`
- This was previously implemented in `controllers/permissions/permissionsMethodMiddleware.js`.
- `test/mocks/permissions.js`
- A truncated version of `test/mocks/permission-controller.js`.

We're bumping from `^6` to `^8`. All imports are now named, and they have been updated. This is a breaking change, in that support for `eth_signTransaction` is added in `^8.0.0`. We do not support this method in our UI, so our middleware stack has been instrumented to reject.
In addition, there are some non-breaking behavioral changes in this version that reviewers should be aware of, see the [7.0.0 release](https://github.com/MetaMask/eth-json-rpc-middleware/releases).

The fixture server now supports state substitutions. This allows us to
embed dynamic values in our fixtures.
The `custom-token` fixture has been updated to include such a fixture.
The date that the seed phrase reminder was last shown has been updated
to always be the current date, to prevent the reminder from showing up
during e2e tests. This fixes the e2e test failure for the test
"add-hide-token.spec.js" that we've been seeing on CI lately.
The npm scripts used to run Mocha scripts have been greatly simplified.
As we transition more tests from Mocha to Jest it was becoming
increasingly difficult to update the CLI arguments to keep all of these
scripts working correctly. This reorganization should make that process
much simpler.
The base Mocha options are in `.mocharc.js` - all except for the target
tests to run. Those are still given via the CLI. There is a second
config file specifically for the `test:unit:lax` tests (i.e. the Mocha
tests that have no coverage requirements) because it requires a change
to the `ignored` configuration property. We can create an additional
configuration file for each test script we add that needs further
configuration changes.
The `test:unit:path` script used to be used to run Mocha tests at a
given path. Now that can be done using `yarn mocha` instead, so this
script has been removed.
The `yarn watch` command has been broken for some time now, so it has
been removed as well. Mocha tests can still be run with a file watcher
using `yarn mocha --watch <path>` or `yarn test:unit:mocha --watch`.
The README has been updated to remove references about the `watch`
command that was removed. I considered explaining the other test
scripts there as well, but they were difficult to explain I will
attempt to update the README after making further simplifications
instead.
This PR fixes our local unit test package scripts. When the state migration unit tests were migrated to Jest in #12106, it left the `test:unit` script in a broken state, because it didn't tell `mocha` to ignore the state migration tests.
Arguably, that script was already broken, since the most reasonably expectation from its name is that it runs _all_ unit tests. The PR makes it so that it does just that, by means of `concurrently`.
Unfortunately, `concurrently` only outputs errors from child processes once (at the time when they exit, https://github.com/open-cli-tools/concurrently/issues/134). This means that we have to search/navigate the output for this combined script to identify the failure. That said, it's better than the status quo.

This PR adds build-time code exclusion by means of code fencing. For details, please see the README in `./development/build/transforms`. Note that linting of transformed files as a form of validation is added in a follow-up, #12075.
Hopefully exhaustive tests are added to ensure that the transform works according to its specification. Since these tests are Node-only, they required their own Jest config. The recommended way to work with multiple Jest configs is using the `projects` field in the Jest config, however [that feature breaks coverage collection](https://github.com/facebook/jest/issues/9628). That being the case, I had to set up two separate Jest configs. In order to get both test suites to run in parallel, Jest is now invoked via a script, `./test/run-jest.sh`.
By way of example, this build system feature allows us to add fences like this:
```javascript
this.store.updateStructure({
...,
GasFeeController: this.gasFeeController,
TokenListController: this.tokenListController,
///: BEGIN:ONLY_INCLUDE_IN(beta)
PluginController: this.pluginController,
///: END:ONLY_INCLUDE_IN
});
```
Which at build time are transformed to the following if the build type is not `beta`:
```javascript
this.store.updateStructure({
...,
GasFeeController: this.gasFeeController,
TokenListController: this.tokenListController,
});
```

There are a few issues encountered when running `yarn setup` on new
Apple Silicon (aka M1, aka arm64) Macs:
* The script halts when attempting to run the install step for
the `chromedriver` package with the message "Only Mac 64 bits
supported". This is somewhat misleading as it seems to indicate that
chromedriver can only be installed on a 64-bit Mac. However, what I
think is happening is that the installation script for `chromedriver`
is not able to detect that an arm64 CPU *is* a 64-bit CPU. After
looking through the `chromedriver` repo, it appears that 87.0.1 is the
first version that adds a proper check ([1]).
Note that upgrading chromedriver caused the Chrome-specific tests to
fail intermittently on CI. I was not able to 100% work out the reason
for this, but ensuring that X (which provides a way for Chrome to run
in a GUI setting from the command line) is available seems to fix
these issues.
* The script also halts when attempting to run the install step for
the `electron` package. This happens because for the version of
`electron` we are using (9.4.2), there is no available binary for
arm64. It appears that Electron 11.x was the first version to support
arm64 Macs ([2]). This is a bit trickier to resolve because we don't
explicitly rely on `electron` — that's brought in by `react-devtools`.
The first version of `react-devtools` that relies on `electron` 11.x
is 4.11.0 ([3]).

Adds the latest version of `@metamask/controllers`, and updates our usage of the `ApprovalController`, which has been migrated to `BaseControllerV2`. Of [the new `controllers` release](https://github.com/MetaMask/controllers/releases/tag/v15.0.0), only the `ApprovalController` migration should be breaking.
This is the first time we use events on the `ControllerMessenger` to update the badge, so I turned the messenger into a property on the main `MetaMaskController` in order to subscribe to events on it in `background.js`. I confirmed that the badge does indeed update during local QA.
As it turns out, [MetaMask/controllers#571](https://github.com/MetaMask/controllers/pull/571) was breaking for a single unit test case, which is now handled during setup and teardown for the related test suite (`metamask-controller.test.js`).
