The State of PHPUnit

  1. 1. THE STATE OF PHPUNIT Volker Dusch / @__edorian
  2. 2. ABOUT ME PHP since 10 years CI CleanCode DevOps TDD Shipping
  3. 3. GET IN TOUCH stackoverflow: Twitter: @__edorian Xing / G+: Volker Dusch IRC: edorian Mail:
  4. 4. LET'S GO
  5. 5. Unit testing in PHP got mainstream
  6. 6. THAT'S A GOOD THING! Unit testing got "normal" in PHP Even people that don't really know PHP or even the CLI know that they should write unit tests.
  7. 7. AGENDA Current State The EcoSystem Annoying things we got rid of Features you might have missed Upcoming stuff Test suite organization Discussion
  8. 8. CURRENT STATE Version: 3.6.12 Over 60 contributors since 3.6.0 Deep into the 3.6 Bugfix cycle, no new features will be added. Those go into .next French docs thanks to @poum and still current Japanese docs thanks to @m-takagi! If you want to help out:
  9. 9. PHPUNIT.NEXT Next up: 3.7 15+ features 10+ issues fixed Details later
  10. 10. BC Did you like upgrading to PHPUnit 3.6?
  11. 11. BC FREE-ISH We are trying really hard to not introduce any BC breaks. Test listeners trigger one autoload call cwd gets restored after test case parameter cloning behavior Removed deprecated OutputTestCase and that's it
  12. 12. THE ECOSYSTEM & friends
  13. 13. BDD Use Behat, It's great! We're not going to remove the BDD stuff in PHPUnit but It's not being worked on.
  14. 14. WEB INTERFACE? Not sure why you'd want that but someone solved that for you
  15. 15. MOCKING IS UGLY! Real world problems and solutions:[phpunit] mock
  16. 16. MOCKERY Try it! It's great. Afraid it might be hard to set up and use? Look into Works with strict mode, leaves the old API intact and is as easy as writing a comment: casMTs etnsPPntEtnin_okr_etae{ ls yet xed HUi_xesosMceyTsCs /*@okr Fo* * mcey o / poetd$o; rtce fo }
  17. 17. LOTS OF LEGACY CODE? Or whatever "hard to test" is called these days. One of the main purpose of this library is to expose invisible (private or protected) methods and properties to the SUT.
  18. 18. TESTING WEB SERVICES Unit and Integration test web services with the same code? Try wsUnit
  19. 19. IDE SUPPORT Netbeans support improved and they adopted the skeleton- generator Honestly I have no clue about eclipse PHPStorm has really beautiful coverage support by now vim user? : p p n t - c v r g - e t !hui -oeaetx
  20. 20. JENKINS Jenkins template: clover php plugin
  21. 21. TRAVIS CI Awesome for GitHub and collaboration Everyone has the way to run their tests documented by now No really CI but a very cool test runner Use --coverage-text if you want to show off :)
  22. 22. COMPOSER Last week: When someone does the work it it will happen This week: Someone did. Current status at
  23. 23. PHAR The PHP tool format We still have issues with process-isolation and figuring out the nicest way to maintain and build the phars. Hopefully the 3.7 alpha will also feature a 3.6 & 3.7 phar.
  24. 24. PHPUNIT-SELENIUM Now maintained by @giorgiosironi Code coverage support If you ask me: Don't drive your web tests with phpunit. Use Behat or something non php.
  26. 26. @ BLOCK When using process-isolation PHPUnit won't die silently when unserializing of the test result fails.
  27. 27. CLI ARGUMENT PARSING ppntTsATsAppTsBTsBpp hui et et.h et et.h This only executed TestA. Now it gives you an error message that you are doing it wrong.
  28. 28. HEY, LISTEN! Test listeners now trigger one autoload call instead of being silently ignored when the class was not loaded.
  29. 29. EXCEPTIONAL Improved reporting of exceptions... pbi fnto tsNseEcpin( ulc ucin etetdxetos) { $3=nwEcpin'he'; e e xeto(Tre) $2=nwIvldruetxeto(To,0 $3; e e naiAgmnEcpin'w' , e) $1=nwEcpin'n' 0 $2; e e xeto(Oe, , e) trw$1 ho e; } because it only told you... EcpintcTs:tsNseEcpin xetoSaket:etetdxetos Ecpin Oe xeto: n [rc] tae but now...
  30. 30. EXCEPTIONAL ...we are printing out the previous exception names, messages and traces. EcpintcTs:tsNseEcpin xetoSaket:etetdxetos Ecpin Oe xeto: n [rc] tae Cue b asd y Ivldruetxeto:To naiAgmnEcpin w [rc] tae Cue b asd y Ecpin Tre xeto: he [rc] tae
  31. 31. ????????????????? Fixed an annoying crash when using --process-isolation with PHP 5.3 and detect_unicode=on.
  32. 32. EVEN MORE EXCEPTIONAL @xetdxeto xeto epceEcpin Ecpin Works again!
  33. 33. ONE MORE THING Ftlerr Ucuh ecpin'HUi_rmwr_xeto'wt msae'e aa ro: nagt xeto PPntFaeokEcpin ih esg Ni te "et.h"nr"et.h"cudb oee. i .. hr tsspp o tsspp ol e pnd' n . That one is still alive. Sorry ;) It just means that PHPUnit can't find any tests.
  35. 35. LINE ENDINGS MISMATCH Ise0Ts:tsCmaeifrnLnEdns su53et:etoprDfeetienig Fie asrigta tosrnsaeietcl ald setn ht w tig r dnia. --Epce - xetd ++Ata + cul @ @ @ @ #ann:Srnscnandfeetln edns Wrig tig oti ifrn ie nig! fo o
  36. 36. IMPROVED THE JSON LOG If tests produce output it is now properly included in the log.
  37. 37. BOOTSTRAP ORDER Bootstrap script should be loaded before trying to load testSuiteLoaderClass.
  38. 38. PROCESS ISOLATION FOR EVERYONE Process Isolation did not work when PHPUnit is invoked through Apache Ant, for instance, due to PHP binary detection issues.
  39. 39. @EXPECTEDEXCEPTIONCODE Now can be 0 or a string. Useful for PDO
  40. 40. BINARY MESS Before it broke your terminal and BEEPed at you 1 Foet:eto ) oTs:tsFo Fie asrigta tosrnsaeeul ald setn ht w tig r qa. --Epce - xetd ++Ata + cul @ @ @ @ - +☺♥☻♦ +♀ ♂ +☼◄‼§↨↓←↔▼ ♫►↕¶▬↑→∟▲ Now it shows a hex dump: Bnr Srn:0000000..... iay tig x012345....
  41. 41. ONE LINE ANNOTATIONS You can use: /*@xetdxeto uaEcpin* * epceEcpin Fbrxeto /
  42. 42. COUNTING ON IT Now working with Countable and Iterator Interfaces: assertCount() assertAttributeCount() assertNotCount() assertAttributeNotCount() assertSameSize() assertNotSameSize()
  43. 43. FLUENT INTERFACES A little mock improvement: -wl(ti-rtrSl() >il$hs>eunef);
  44. 44. @REQUIRES /* * *@eursPP54 rqie H . */ pbi fnto tsTat) ulc ucin etri( { }
  45. 45. REQUIRES <ie fl ppeso=530 hVrin".." ppesoOeao=>" hVrinprtr"= > /aht/yetpp pt/oMTs.h <fl> /ie
  46. 46. MAGIC SUPPORT assertEquals() now looks for (and invokes) a __toString() method when an object and string are compared.
  47. 47. PERFORMANCE setUpBeforeClass() and tearDownAfterClass() are no longer invoked when all tests of the class are skipped
  49. 49. LESS MAGIC NUMBERS @expectedException* now works with constants: /* * *@xetdxeto Cas epceEcpin ls *@xetdxetoCd @ls:TAO_ISN epceEcpinoe Cas:EPTMSIG *@xetdxetoMsae@ls:TAO_ISN_ESG epceEcpinesg Cas:EPTMSIGMSAE */ Reduce copy paste testing.
  50. 50. *TEST.PHP IS TOO MAINSTREAM Added --test-suffix that allows specifying which filename suffixes are recognised by PHPUnit. Helps out some projects with their CI. I don't see a general use case.
  51. 51. {"JSON": "YES PLEASE"} We added assertJson* functions that work like the existing assertXml* functions. asrJoFlEulJoFl( setsnieqassnie) asrJoSrnEulJoFl( setsntigqassnie) asrJoSrnEulJoSrn( setsntigqassntig)
  52. 52. CALLBACK MATCHER Helps with complex assertions on mocks pbi fnto sn(msae EdonCni $ofg ulc ucin ed$esg, npitofg cni) It's not pretty but it might solve that one annoying problem: $o-epcs$hs>ne) fo>xet(ti-oc() -mto(sn' >ehd'ed) -wt( >ih $hs>qaT(sn) ti-eulo'y', $hs>alak ti-clbc( fnto (cni){ ucin $ofg $r =$ofg>eUl) ul cni-gtr(; i($r){trwnwEcpin'..) } f!ul ho e xeto(..'; rtr $r-gtot)=='tp/eapecm; eun ul>eHs( = ht:/xml.o' } ) );
  53. 53. OO-ARRAYS asrAryaKy) setraHse( asrAryoHse( setraNtaKy) Now work with objects that implement ArrayAccess.
  54. 54. PHPUNIT.XSD PHPUnit now provides a configuration.xsd schema file. Useful to validate your phpunit.xml and phpunit.xml.dist configuration files. <xlvrin"."ecdn=UF8? ?m eso=10 noig"T-"> <hui ppnt xlsxi"tp/www.r/01XLceaisac" mn:s=ht:/w.3og20/MShm-ntne xinNmsaeceaoain s:oaepcShmLcto =ht:/ceappntd/ofgrto.s" "tp/shm.hui.ecniuainxd [.] .. >

  58. 58. .PHPT IMPROVEMENTS Before 3.7 diffs where really hard to read. Now the diff will be processed line by line.

  61. 61. LESS REQUIRES, LESS CRASHES <htls adnoeeFlsrmhtls=tu" wieit dUcvrdieFoWieit"re> People seem to constantly run into issues with code coverage <htls poesnoeeFlsrmhtls=tu" wieit rcsUcvrdieFoWieit"re> When enabled, uncovered whitelisted files are processed to properly calculate the number of executable lines. If not we take a quite ok guess to get the number of ELOC.

  66. 66. SMALL HINTS Use the xml configuration for pretty much everything Separate unit and integration tests Your unit test folders should mirror your applications folder structure To only execute specific tests use phpunit --filter or phpunit tests/unit/module1 Use the strict mode from the get go and never turn it off. Imho: Don't have a test namespace. Nicer to read and shows production usage.
