• Github actions for CI
• Jetpack libraries(ViewModel, Activity)
• Coroutines + retrofit for http requests
• Kotlinx.Serialization for JSON handling
• Detekt & formatting(ktlint) for static analysis

Testing stack

• Activity Scenario for unit and instrumented testing
• robolectric for unit testing
• Espresso assertions for UI testing
• Screenshot Tests for Android for chart testing
• MockWebServer for API and integration testing

CI

The CI machine run the following steps:

1. detekt & formatting (ktlint)
2. unit tests
3. instrumented testing
4. snapshot tests

Quick Start

How to run?

This project is being built using Android studio 4.1.3, so, I do recommend install the latest stable version.

Running from CLI

./gradlew test will run all unit testing ./gradlew detekt will run detekt ./gradlew connectedVariantNameAndroidTest will run instrumented tests

Snapshot testing

To run snapshot testing you need:

1. install python 2.7
2. python-pillow
3. ANDROID_HOME mapping your sdk path
4. Run snapshot testing using Pixel 3 device API 27

./gradlew verifyDebugAndroidTestScreenshotTest to run snapshot testing
