Transcript

  • 1. Testing Mobile JavaScript John Resig June 2010
  • 2. I’ve been researching and trying to make sense of the mobile space recently. Started preparations in 2009 (with the creation of TestSwarm).
  • 3. Cross-browser mobile web development is crazy. (...but not nearly as crazy as it use to be.) I’ve seen things...
  • 4. A Simple Goal ✤ Started with a simple goal: ✤ To make sure that jQuery works on the most popular mobile platforms and browsers. ✤ As it turns out, it’s really hard to define the scope of the problem.
  • 5. Questions: Answered ✤ Three questions that need to be answered before doing mobile development: ✤ What platforms and browsers are popular? ✤ What browsers are capable of supporting modern scripting? ✤ What devices and simulators do I acquire to test with? ✤ To answer those questions we need good data.
  • 6. Best Stats? ✤ Who has the best statistics on the mobile market? ✤ StatCounter and Gartner seem to be tops. ✤ StatCounter covers billions of hits per month. ✤ Gartner is well-respected and knows sale information well. ✤ AdMob is decent for specific platforms (iPhone, Android). ✤ That being said: Very little actually-useful information leaks out.
  • 7. Lack of Information ✤ Right now finding this information is a challenge. ✤ As a result, developers develop for what’s in front of them:
  • 8. Platforms
  • 9. Platform Sales
  • 10. Hard Question ✤ What versions of those platforms are popular? ✤ No one seems to know, or isn’t talking about it.
  • 11. Browsers
  • 12. Hard Question ✤ What versions of those browsers are popular? ✤ No one seems to know, or isn’t talking about it. ✤ Supposedly Yahoo is going to be releasing some information soon, we’ll see. ✤ Right now it’s considered to be a competitive advantage to keep it private.
  • 13. Testing Strategy ✤ Draw a line in the sand ✤ Buy Devices, Download Simulators ✤ Automate testing (TestSwarm!)
  • 14. Drawing a Line ✤ Yahoo!s Graded Browser Support technique is optimal. ✤ Qualify which browsers you will support (actively test against) and give them a grade. ✤ A = Full support, C = Fall back to old site, Other = Assume full support.
  • 15. My God... it’s full of browsers... Mobile Graded Browser Support: Market share + Browser quality
  • 16. Testing Browsers ✤ Two options: ✤ Buy devices and/or ✤ Download simulators ✤ Simulators are good for most automated testing. ✤ Any sort of interaction testing you’ll want to do on a physical device. ✤ Always good to do a sanity check on a physical device before going live.
  • 17. Simulators ✤ Simulators are available for most platforms and browsers. ✤ Most simulators require Windows to run (some require Perl or Java) ✤ Some browsers even provide standalone executables (Opera, Fennec). ✤ Getting the simulators running can be a real bear.
  • 18. Automated Testing ✤ Once you have simulators (or physical devices) up and running you’ll want to interact with them as little as possible. ✤ Automated test execution will be really important. ✤ TestSwarm was developed for this express purpose: Make it easy to push tests out to a large number of clients (even mobile).
  • 19. Platforms ✤ Symbian (S60 / UIQ) ✤ iPhone OS ✤ Blackberry OS ✤ Android ✤ Windows Mobile ✤ WebOS ✤ Maemo / Meego
  • 20. Symbian
  • 21. Symbian S60 ✤ The most popular mobile OS - heavily used by Nokia. ✤ v5.0 is for touch screen devices (Equiv. to Safari 3.1) ✤ v3.0 is the latest for ‘regular’ devices (Equiv. to Safari 2.0) ✤ 2 ‘feature packs’ have been released ✤ The oldest, active, mobile browser that should be supported. ✤ Simulators available on Nokia.com.
  • 22. Symbian S60 B A B?
  • 23. Symbian UIQ ✤ A now-dead implementation of the Symbian OS last released in 2008. ✤ Appears to still be in use, some what, but quickly becoming irrelevant. ✤ Uses Opera Mobile (8.6, 8.65) as its built-in browser. ✤ UIQ is dead and Nokia doesn’t distribute the simulator any more. I found a guy in Russia that has some extra copies (totally legit, heh).
  • 24. Symbian UIQ C C
  • 25. iPhone OS ✤ Apple’s super-popular mobile OS ✤ Apple is very good about pushing updates, almost all users are on the latest OS version. ✤ Current with Safari 4 ✤ A gotchya: Does not have fixed position support (making it difficult to implement toolbars). Recommend: TouchScroll library. ✤ Simulator is part of the iPhone SDK.
  • 26. iPhone Simulator No 2.x simulator! B A A
  • 27. Blackberry OS ✤ Blackberry continues to be enormously popular - and growing rapidly. ✤ Ships with a custom browser, will be switching to a WebKit-based one in 6.0. ✤ Anything older than Blackberry 4.6 is really frightening. ✤ Andrew Dupont calls 4.6 the “rubicon”. ✤ 4.6/4.7 have some strange quirks, 5.0 is pretty decent. ✤ Blackberry provides simulator downloads on their dev site.
  • 28. Blackberry OS B B B
  • 29. Android ✤ Rapidly growing OS from Google. ✤ Tons of manufacturers are modifying and shipping it. ✤ Expect Android to grow drastically over the next couple years. ✤ Lack of control has yielded extreme version fracturing. ✤ Simulators are an easy download.
  • 30. Android A A A
  • 31. Windows Mobile ✤ Windows Mobile 6.5 is the current release. ✤ Uses IE 6 as its rendering engine. ✤ Window Mobile 7.0 is coming soon. ✤ Uses IE 7 as its rendering engine. :-( :-( :-( :,( ✤ Window Mobile 6.1 is still relatively popular but is based off of IE 4.0 - this is a non-starter. ✤ Windows Mobile 6.5 simulator is an easy download.
  • 32. Windows Mobile 7.0? :-( F B
  • 33. WebOS ✤ Palm’s (HP’s?) Mobile OS ✤ Has a minimal amount of traction. ✤ Built off of WebKit, easy to support. ✤ 1.4 simulator ships with 1.3 browser (wtf!?) ✤ I’m testing using a physical Palm Pre. ✤ Palm Pre simulator is an easy download. A
  • 34. Maemo / Meego ✤ Linux-based OS used for tablets (and potentially phones). Used by Nokia. ✤ Not very popular. ✤ Has a browser called ‘MicroB’ that C uses Gecko. ✤ Mostly interesting as Fennec is capable of running on it. ✤ Simulator requires Linux to run - haven’t figured it out yet.
  • 35. Platform-Independent Browsers ✤ A number of browsers target multiple platforms. Some work directly with carriers (Opera, Netfront) whereas others provide downloads (Opera, Fennec). ✤ Opera ✤ Fennec ✤ Netfront ✤ Phonegap (App Platform)
  • 36. Opera Mobile and Opera Mini ✤ Hugely popular mobile browser (especially Mini). ✤ Available on a large number of platforms. ✤ Even ships as the default browser on some. ✤ Opera Mobile and Opera Mini couldn’t be more different. ✤ Mobile is a full-featured browser. ✤ Mini is a glorified bitmap viewer. ✤ Pulls from a proxy, no JS executing on client.
  • 37. Opera Mobile and Opera Mini C A C Simulator is awesome!
  • 38. Fennec ✤ Codename for Firefox on mobile devices ✤ Released for Maemo, alpha release out for Android (watch this!) A B ✤ Equivalent to the latest releases of Firefox Simulator is awesome!
  • 39. Netfront ✤ Used on Playstation and N-Gage ✤ Download available for Windows Mobile. ✤ Highly crippled, custom, browser. ✤ Not worth supporting. C ✤ Compatibility can be a real pain.
  • 40. Phonegap ✤ Not a browser, a way to develop cross-platform applications. ✤ Uses WebKit as the rendering engine. ✤ Use HTML/CSS/JS to develop deployable apps. A ✤ Quite popular, easy to support.
  • 41. Other Browsers ✤ Not worth the time for such small market share. ✤ Ozone (Uses WebKit) ✤ Openwave (Dead) ✤ Bolt (Uses WebKit) C ✤ JIL (Uses WebKit, Widget Platform)
  • 42. Summary ✤ What do we need to support? Roughly: ✤ Opera 9.5, 10 ✤ Internet Explorer 6, 7 ✤ Firefox 3.5+ ✤ Safari 2, 3, 4 ✤ (and Blackberry... weeee...) ✤ Don’t assume it’ll work, download the simulators and test!
  • 43. What Devices to Buy? ✤ For A level: ✤ 1 iPhone 3GS: Latest running 3.x (* Watch for new 4.x iPhone) ✤ 1 iPad: Running 3.2 ✤ 1 Nokia N97 Running S60v5 ✤ 1 Palm Pre: Running 1.4 ✤ 2 Android Phones: HTC Magic (1.5/1.6), Droid Incredible (2.1) (* Watch for new 2.2 Android) ✤ And download the Opera and Fennec Simulators and Phonegap
