Improve test failure readability (#18049)
Problem: failed equality checks as in "(is (= expected actual))" will give a
single, long line of output that for anything but the simplest data structures
is unreadable by humans, and the output doesn't give a useful diff.

Solution: use library https://github.com/nubank/matcher-combinators and its test
directive "match?" which will pinpoint where two data structures differ. Then,
instead of "(is (= ...", use "(is (match? expected actual)". It works
beautifully.

The library offers other nice matchers, but the majority of the time match? is
sufficient.

Can we use another test runner like Kaocha? kaocha-cljs2
(https://github.com/lambdaisland/kaocha-cljs2) would be able to print better
test errors out of the box, among other features, but I have no clue if it would
work well or at all in our stack (in theory yes, but it's a larger piece of
work).

README.md

Description

This folder contains configuration for Nix, a purely functional package manager used by the Status app for its build process.

Configuration

The main config file is nix/nix.conf and its main purpose is defining the binary caches which allow download of packages to avoid having to compile them yourself locally.

Build arguments

We leverage the environment variables for parameterization of the builds (e.g. to pass a build number or build type).

Here is the list of variables you can use to override defaults:

# Build type (influences which .env file gets used for feature flags)
export BUILD_TYPE="pr"
# Used for versionCode and CFBundleVersion in Android and iOS respectively
export BUILD_NUMBER=9999
# Gradle options passed for Android builds
export ANDROID_GRADLE_OPTS=""
# If APKs should be split based on architectures
export ANDROID_ABI_SPLIT=false
# Android architectures to build for
export ANDROID_ABI_INCLUDE="x86"
# Local source override, see below
export STATUS_GO_SRC_OVERRIDE="$HOME/my/source/status-go"
export STATUS_GO_IPFS_GATEWAY_URL="https://ipfs.status.im/"

You can see the defaults in code:

Shell

In order to access an interactive Nix shell a user should run make shell.

The Nix shell is started in this repo via the nix/scripts/shell.sh script, which is a wrapper around the nix-shell command and is intended for use with our main Makefile. This allows for an implicit use of nix-shell as the default shell in the Makefile.

Normally the shell starts without any specific target platform, if you want to change that you should export the TARGET env variable with appropriate value:

make shell TARGET=android

This way your shell and all other nix commands should run in a setup that is tailored towards Android development.

For valid values you can check the nix/shells.nix file.

⚠️ WARNING: To have Nix pick up all changes a new nix-shell needs to be spawned.

Using a local status-go repository

If you need to use a locally checked-out status-go repository, you can achieve that by defining the STATUS_GO_SRC_OVERRIDE environment variable:

export STATUS_GO_SRC_OVERRIDE=$GOPATH/src/github.com/status-im/status-go
make release-android
