Mobile Landscape and Testing Challenges

MOBILE LANDSCAPEMOBILE TESTING CHALLENGES

Do you know how many babies are born each day? • 371,000 DAILY

Impressive, until you realize the number iPhones sold • 377,900 DAILY ( Luke Wroblewski (@lukew) January 24, 2012 ) • 515,000 DAILY ( Q2 2012 - BI)

Or the number of Android phones activated. • 1.3M DAILY (Eric Schmidt – 9/5/12)

And letʼs not forget the growth of tablets. • 277,800 DAILY (just iPad – 189k daily in Q2 – WSJ Oct 1/2012)

Mobile HTML5 Based Automation

Native Platform Automation Technologies

Platform Independent Mobile Automation – Type A

Platform Independent Mobile Automation – Type B

• Drives HTML and JS constructs

• Recognizes Web Controls

• Drives GUI widgets and Controls on the Native UI Layer

• Leverages screen coordinates, images and OCR to drive automation

• Drives GUI widgets and Controls on the Native UI Layer

• Cross device platforms

• Cross browsers• Object aware

automation• Non Intrusive to App

• Ultimate control as good object level UI layer access

• Cross platform scripting, one script many devices.

• Has access to the whole device

• Good control over GUI and executing app

• Object aware automation

• Limited to Web and Cross Platform HTML5 Apps

• Intrusive, often requires code access

• Written specifically for a device platform

• Limited to the context of the application

• Limited object awareness, reliance on image and OCR

• Less effective for complex automation

• Intrusive will likely take a special build.

• May or may not require jail breaking

• Limited to the context of the application

DEVICES SELECTIONHow do you identify the Devices for Mobile Automation?

Objective: Maximum Coverage at Minimum Cost (&time)

Type of the App• Games• Social• Business

User Personas• Business• Teen• Social

Geography• Asia Pac• Americas etc.

App Functions• Streaming• Screen Res• GPS etc.

TEST CASE SELECTIONHow do you identify the test cases for Mobile Automation?

• System/Peripheral Interaction• Interaction between multiple apps/ OS-App /Multi Domain• Location aware, peripheral, battery life, system alerts etc.

Tool and Resource Capability

• Best Practices for other GUI Automation apply• UI components that will change less.• Clear understood business processes

Stability/Change

• Less graphically intensive , more data and business scenarios• Medium complexity test cases - > High - > Low• Smoke - > High - > Medium - > Low

Devices

Dealing with Special Device Conditions

• CPU Usage, RAM, Network Conditions, Other Apps, Environment conditions, Light Conditions

App Misbehave in Special Conditions…

• Android – system panel app / Task Manager• iPhone – System and Monitoring Tools

Handy Tools

• Remotely sets device in desired and specific conditions – CPU, RAM, Network, Light etc.

• Accessible from Automated scripts.

InfoStretch Device Stressor

What Special Conditions?

Execution Best Practices

• Device characteristics• Test script errors• Automation tool instability• Device instability• Data instability

Automation Tests will break due to

• Develop agents that can restart test components on devices e.g. if webdriver • Enhance test case recovery, capability to restart test case.

Invest in Robust Test Recovery System

• Details trace of the test• Immediately tells you the failures

Invest in Logging from the test cases

DEVELOP STRONG TEST RECOVERY

CI INTEGRATION - REFERENCE

AUTOMATING THE AUTOMATION

• Automate execution of test cases• Integrated automated reporting, and notifications• Prominent tools – Jenkins, hudson

What is CI?

• There is no Automation until its Automated • Well justified effort, easy ROI, pays off in Days• Automated trending and device comparisons.

Why CI?

• Dedicated automation devices

Invest in a Test Automation lab of devices

INVEST IN CONTINUOUS INTEGRATION (CI)

OUR CI INTEGRATION

CASE STUDY

Automated a mobile web based application that enables the ability for passengers to book and manage travel on their iOS and Android mobile devices through a simple and intuitive process flow.

Development and Manual Testers defined 33 user scenarios test cases for automation to detect regressions.

Test cases are categorized by a. Book My Flightb. Manage My Flightc. Check Flight Statusd. Feature Function Test – integrated testing with the

above 3 categories

Automation starts as soon as Manual tests verify each functionality.

Application compatibility testing with system notifications are manually tested.

BUSINESS PROBLEM

Automation Tool Selected: Selenium Remote Android and IOS web driver. Automated tests limited to the Sabre web application only. Selenium based solution does not support automated application compatibility i.e. system alerts – phone calls while application is running and Blackberry devices - Perfecto Mobile test automation can be used in this case.

Selenium Test Suites

Webdriver installed on each mobile devices

Jenkins CI

Test Code Repository

Monitor for regression

Test on Firefox first – as baseline, then move to mobile devices

TEST ENVIRONMENT

• Element ID Discovery – – Test code dependent on locator id changes and UI flow changes especially in agile scrum development

environment. Colocation is critical to promote communication. – Xpath not supported on all mobile devices.

• Selenium Web driver – connection reset when executing whole test suites on iOS and Android devices on a single run.– Web driver not responsive at times causing timeouts. – Still maturing - monthly releases

• On Android– Android Web driver – delay in populating in list box values. – Problems with launching web applications on Android emulator. – Compatibility across various devices – i.e. On Android 2.3 OS - Samsung Galaxy and Sony Ericson have

different list-box implementations (see next slide)

• On IOS– iOS Web driver does not always reset after test suite run and need device restart.– Installing Web driver on iOS devices requires “jail broken” device and valid provision profile on

device.

SOME TECHNICAL CHALLENGES

• Automation team to be co-located with development team especially with agile scrum teams.

• Establish policy to ensure locator ids backward compatibility between sprints.

• Due to the variability of devices and web driver behaviors, architect your automation with this theme “when things change, change it in ONE place”.

• Automation scripts should coordinate the highest level abstraction, (libraries) whenever possible to maintain agility and robustness across devices.

• Agreement on list of devices / vendors to be supported. Not all devices will be have the same way.

• Selenium iOS and Android web drivers are still evolving - expect to do debugging

to workaround web driver issues.
