Goals


5 Inspiration


6

Inspiration


7

•  Jenkins •  Multi-configuration Project •  Build Matrix {API-Level}

•  Ant

•  Android Emulator Jenkins Plugin •  Automatic emulator creation •  Snapshots

•  Robotium

•  Emma Code Coverage

•  UIAutomator

Approach (circa 2013)


8 Approach (circa 2013)


9

•  Library projects •  Setup local properties for all projects

•  Android Emulator Jenkins Plugin •  Incompatible combinations •  Emulator unlocking not guaranteed

•  Windows 7 PC – AMD Chipset •  Limited emulator options

Pains


10

•  Jenkins •  Multi-configuration Project •  Build Matrix {Emulator, Language}

•  Gradle (Wrapper)

•  Jacoco Code Coverage Jenkins Plugin •  Android Emulator Jenkins Plugin

•  Static Emulators (Disabled animations) •  Espresso •  Robotium

•  Screenshots Only •  Sonar •  Not Windows

Approach


11

•  Espresso •  Older API levels may idle main thread before transitions

•  Thread.sleep still needed on older API levels •  Android Emulator Jenkins Plugin

•  Still not guaranteed to unlock device •  Fixed with shell commands to unlock device

•  Android Gradle Plugin •  Pure unit tests not a possibility •  Next version will support!
