Sonar Co-Locate for Android

Build setup

Some secrets need to be set for the build to run. Please DO NOT add them to the project's gradle.properties. Required secrets are:

sonar.headerValue
sonar.baseUrl

To set a property refer to official gradle documentation

Running tests

Device setup

Make sure all animations are turned off on the device (not an emulator) that is running the tests. https://developer.android.com/training/testing/espresso/setup#set-up-environment

Also ensure that location access is enabled on the device.
Before pushing code run -
```
./gradlew localBuild
```
It is the default task, so you can also just run -
```
./gradlew
```

NOTE

PLEASE NEVER skip running the tests before pushing.
PLEASE NEVER disable tests.
PLEASE NEVER push code to master that knowingly breaks the test suite.

PACT tests

Pact contract tests are run as part of the regular unit test suite. If one of the tests is failing, and you need more output, set slf4j logging to debug: -Dorg.slf4j.simpleLogger.defaultLogLevel=DEBUG

Are your pact tests failing with "problem accessing trust store"?

This is a sign that you are registering encryption provider in a test but are not de-registering it after. Pact will then try to create a client using the Apache SSLSocketFactory. This will in turn try to use the encryption provider as the certificate trust store, resulting in the error you see. To fix, de-register the encryption provider after use in tests.

Running tests on Firebase from your machine

Make sure your APKs are built -

./gradlew localBuild

You will need the gcloud CLI. Once installed run:

./gradlew localBuild

gcloud init
gcloud config set project sonar-colocate
gcloud firebase test android run \
    --type=instrumentation \
    --app=app/build/outputs/apk/debug/app-debug.apk \
    --test=app/build/outputs/apk/androidTest/debug/app-debug-androidTest.apk \
    --device-ids=aljeter_n \
    --os-version-ids=26 \
    --use-orchestrator \
    --environment-variables=clearPackageData=true

Code formatting with KTLint

KTLint has been added to the build and will automatically run when you run the build. It is attached to the check step of the build.

The official Kotlin style guide recommends slightly different configuration from the default Android Studio setup.

The continuation indent should be set to 4
Imports should never use wildcards
Files should end with a new line character.

Play Store

Make sure you have configured the following properties in ~/.gradle/gradle.properties

SIGNING_KEY_ALIAS=<keystore alias>
SIGNING_KEY_STORE=<path/to/keystore>
SIGNING_KEY_STORE_PASSWORD=<keystore password>
SIGNING_KEY_PASSWORD=<key password>
PLAY_SERVICES_PUBLISH=<path/to/play-services.json>

Update the release notes in app/src/main/play/release-notes/en-GB/default.txt
To publish new release in internal test track, run following command in project root directory:
```
./gradlew publish -Pplay-enabled
```
To prompt a release from internal track to alpha (stakeholder) track, run following command in project root directory:
```
./gradlew promoteArtifact -Pplay-enabled
```
