### Why component tests were failing?
Many tests were failing because we were using RN Testing Library (RNTL) in an
unreliable fashion. With the recent library upgrades, the unreliability was
excerbated. Other times, the tests were incorrectly arranging data.
### with-redefs does not work with async code
Generally speaking, with-redefs should not be used with async code, assume the
worst. The scope of the macro will cease to exist by the time the async code
runs. In many tests we were using with-redefs, then calling render, but for some
components that use use-effect, JS timers, animations, etc it's unreliable and
were the reason for failures.
It's easy to reproduce too:
```clojure
(defn foo []
:foo)
(foo)
;; => :foo
(with-redefs [foo (constantly :bar)]
(foo))
;; => :bar
(js/setTimeout
(fn []
(tap> [:calling-foo (foo)]))
100)
;; Taps [:calling-foo :foo]
;; As you would expect, when running without with-redefs, it prints :foo.
;; So far so good, but whatch what happens with async code:
(with-redefs [foo (constantly :bar)]
(js/setTimeout
(fn []
(tap> [:calling-foo (foo)]))
100))
;; Taps [:calling-foo :foo]
;; ====> PROBLEM: Taps :foo, not :bar as one might expect
```
### Not waiting on wait-for
When test-helpers.component/wait-for is used, subsequent assertions/etc should
be done after the promise returned by wait-for is resolved. But remember to not
perform side-effects inside the wait-for callback (check out the docs
https://callstack.github.io/react-native-testing-library/docs/api#waitfor).
Most, if not all of our usages of wait-for were not waiting.
#### Improvement 1 - Silence Jest on demand
If you need to re-run component tests frequently, you may want to reduce the
output verbosity. By passing JEST_USE_SILENT_REPORTER=true to make
component-test or make component-test-watch you will see a lot less noise and be
able to focus on what really matters to you.
#### Improvement 2 - Selectively focus/disable tests
Because of our need to first compile CLJS to JS before running tests via Jest,
we couldn't easily skip or focus on specific tests. From this commit onwards, we
should never again have to change the list of requires in files core_spec.cljs.
Commenting out required namespaces gives a bad DX because it causes constant
rebasing issues.
#### Improvement 3 - Translations now work as in prod code (but only English)
Translations performed by *-by-translation-text can be done now without any
workaround under the hood. The query functions are now linted just like
i18n/label, which means static translation keywords must be qualified with :t/,
which is good for consistency.
This commit does many things :
- Upgrade `react-native ` to `0.72.5`
- Upgrade `react-native-reanimated` to `3.5.4`
- Upgrade `react-native-navigation` to `7.37.0`
- `ndkVersion` has been bumped to `25.2.9519653`
- `cmakeVersion` has been bumped to `3.22.1`
- `kotlinVersion` has been bumped to `1.7.22`
- `AGP` has been bumped to `7.4.2`
- `Gradle` has been upgraded to `8.0.1`
- Android `CompileSDK` and `TargetSDK` have been bumped to 33
- `@react-native-async-storage/async-storage` has been upgraded to `1.19.3`
- `@walletconnect/client` has been nuked
- some of the old `react-native-reanimated` code has been nuked
- `react-native-keychain` fork has been replaced with `8.1.2`
- On Android we are currently relying on `Hermes` Engine.
- On iOS we are currently relying on `JSC`
- We are not enabling new architecture for now (I have plans for that in the future) ref: https://github.com/status-im/status-mobile/issues/18138
IOS only PR : https://github.com/status-im/status-mobile/pull/16721
Android only PR : https://github.com/status-im/status-mobile/pull/17062
- `make run-metro` now has a target of `android` which was `clojure` earlier, this will increase the time it takes to start metro terminal but this is needed otherwise you will get a nasty error while developing for android locally.
This commit is the foundational step to start using malli
(https://github.com/metosin/malli) in this project.
Take in consideration we will only be able to realize malli's full power in
future iterations.
For those without context: the mobile team watched a presentation about malli
and went through a light RFC to put everyone on the same page, among other
discussions here and there in PRs.
To keep things relatively short:
1. Unit, integration and component tests will short-circuit (fail) when
inputs/outputs don't conform to their respective function schemas (CI should
fail too).
2. Failed schema checks will not block the app from initializing, nor throw an
exception that would trigger the LogBox. Exceptions are only thrown in the
scope of automated tests.
3. There's zero performance impact in production code because we only
instrument. Instrumentation is removed from the compiled code due to the
usage of "^boolean js.goog/DEBUG".
4. We shouldn't expect any meaningful slowdown during development.
**What are we instrumenting in this PR?**
Per our team's agreement, we're only instrumenting the bare minimum to showcase 2 examples.
- Instrument a utility function utils.money/format-amount using the macro
approach.
- Instrument a quo component quo.components.counter.step.view/view using the
functional approach.
Both approaches are useful, the functional approach is powerful and allow us to
instrument anonymous functions, like the ones we pass to subscriptions or event
handlers, or the higher-order function quo.theme/with-theme. The macro approach
is perfect for functions already defined with defn.
**I evaluated the schema or function in the REPL but nothing changes**
- If you evaluate the source function, you need to evaluate schema/=> or
schema/instrument as well.
- Remember to *var quote* when using schema/instrument.
- You must call "(status-im2.setup.schema/setup!)" after any var is
re-instrumented. It's advisable to add a keybinding in your editor to send
this expression automatically to the CLJS REPL, or add the call at the end of
the namespace you are working on (similar to how some devs add "(run-tests)"
at the end of test namespaces).
**Where should schemas be defined?**
For the moment, we should focus on instrumenting quo components, so define each
function schema in the same namespace as the component's public "view" var.
To be specific:
- A schema used only to instrument a single function and not used elsewhere,
like a quo component schema, wouldn't benefit from being defined in a separate
namespace because that would force the developer to constantly open two files
instead of one to check function signatures.
- A common schema reused across the repo, like ":schema.common/theme" should be
registered in the global registry "schema.registry" so that consumers can just
refer to it by keyword, as if it was a built-in malli schema.
- A common schema describing status-go entities like message, notification,
community, etc can be stored either in the respective
"src/status_im2/contexts/*" or registered globally, or even somewhere else.
This is yet to be defined, but since I chose not to include schemas for them,
we can postpone this guideline.
