This document discusses build automation for mobile applications. It recommends using Jenkins for continuous integration to run tests and analyze code quality after each code push. The document outlines a sample build pipeline in Jenkins that would compile, run linting, tests, static analysis with Sonar, and monkey testing before distributing builds. It also discusses using Git, Git Flow, Gradle flavors for testing, and services like Crashlytics for beta distribution to reliably deliver high quality apps. Frequent testing, code analysis, and build automation are emphasized to catch issues early and ensure only stable releases are distributed.

6 Release Process the future Everything you have to do afterwards is git push
7 Release Process the future
8 Build Automation What will we be using jenkins Test Driven Development Git Beta Distribution Nightly Versions Gradle
9 Build Automation Benefits ? New Features are Live ASAP ? As Soon As Pushed ? Only Stable and Tested Builds can be Pushed ? No more unstable Releases ? Less Human Testing ? No more Sharing of Sensitive Data ? Keystores ? Logins
10 Build Automation Jenkins Jenkins is an award-winning application that monitors executions of repeated jobs, such as ? Building/testing software projects continuously ? Monitoring executions of externally-run jobs Get Jenkins at: http://jenkins-ci.org/
11 Build Automation Build Pipeline ? Sample Build Pipeline: compile lint Tests sonar monkey runner distribute
12 Build Automation Build Pipeline ? Distribution will only Happen if all Previous Steps Succeed ? Tests, Code Analysis, etc. can Run Parallel ? Step by Step enables Failing Fast ? Resource Hungry Jobs like Monkey Runner will be triggered only if needed
13 Jenkins Usefull Tipps ? Clone Workspace SCM Plugin ? Shared Workspaces may have locks ? https://wiki.jenkins-ci.org/display/JENKINS/Clone+Workspace+SCM+Plugin ? Polling Sucks ? use Git Hooks! ? Do not run on a Small Virtual Machine ? Android Emulator needs some Hardware ? Intel HAX strongly Recommended!
14 Jenkins Build Monitor Plugin
15 Jenkins Build Pipeline View Plugin
16 Jenkins Monitoring Plugins
17 Build Automation gradle ? Best of ANT / Maven / GANT / Ivy ? Based on Groovy Scripts ? Expressive DSL ? (Flexible) Convention over Configuration ? Easy to extend ? ?Make the impossible possible, make the possible easy and make the easy elegant.¡±
18 gradle flavoring ? Staging, Dev and Live Packages ? On Your Test Device no Constant Uninstalling ? Adjustable Configurations without Code Changes ? Why? ? Reproduce able builds, easy setup
19 gradle sample Code
20 gradle sample Code Project Setup Flavoring ? Same Folder Structure for every Flavor ? Flavor Specific files Overwrite Files from Main ? Only Overwrite What your Flavor Needs ? Flavor Only Files Possible
21 gradle sample Code Example Flavor Specific Manifest ? Only Provider defined ? Everything else comes from main/AndroidManifest.xml
22 Build Automation git ? Branching ? Opensource ? Integrated and Extended Implementations
23 Git Git Workflow Git Flow Branching Model source: www.atlassian.com
24 Jenkins Git Flow and Jenkins Examples ? Staging ? Hook on develop Branch ? Nightly ? Time Based Build (eg once a day at 0 AM) ? builds newest feature Branch ? Live ? Only Builds release Tags ? Release Notes are Tag Message
25 Beta Test Distribution
26 Beta Test Distribution Examples ? Google Play ? Alpha / Channel ? Works on every Device that has The Playstore ? Crashlytics ? Distribution Groups & User Level ? gradle Integration ? free ? HokeyApp ? Comercial
27 Unit Testing WHY? Testing - Do it
28 Unit Testing WHY?
29 Unit Testing WHY? ? Code Quality Matters! ? Insurance everything still works ? As it should be working ? Refactoring made easy ? Unittests are somehow a Functional Documentation
30 Unit Testing Some Tipps: ? Tests first! ? Simplest and dumbest way to implement ? Test Orientation Changes ? Test State Changes ? Lock Screen ? Incoming calls ? etc. ? Check Code Coverage
31 Test Frameworks Unittests ? Robolectric ? No Emulator Needed ? No Mocking Frameworks Needed ? API Level Emulation only up to 18 (currently) ? Robotium ? Silenium for Android ? User Scenarios ? Default Android Testing Framework
32 Test Frameworks UI Testing ? Espresso ? Ui Testing ? Double Espresso ? Espresso Gradle Port ? Ui Automator ? Android Default UI Testing Framework

41 Build Automation Static Code Analysis
42 Build Automation Static Code Analysis ? Testing your Application makes your life more Stress free ? Code Quality ? Less Production Crashes ? Don¡¯t develop Stuff that should not go live ? Use Gradle Flavors!

Editor's Notes

  1. Imperative No phases Hard to read Flexbile Hard to extend No conventions (init, setup,..)
  2. Dynamically create execution order
  3. Groovy based build system based on ant
  4. Groovy based build system based on ant
