WHO AM I?  Xavier Decoster  Antwerp, Belgium  www.realdolmen.com  Co-founder of MyGet.org  Focus on ALM/Web  http://www.xavierdecoster.com  @xavierdecosterMAY 8, 2012 | SLIDE 3

AGENDA  Continuous Integration  Room for Improvement  Dealing with dependencies  Versioning  VCS issues  Debugging  Package Management  One step closer to Continuous Delivery?  1 + 1 = Optimize for HappinessMAY 8, 2012 | SLIDE 4

Do you speak it? CONTINUOUS INTEGRATIONMAY 8, 2012 | SLIDE 5

DISCLAIMER  Not saying “my way” must be “your way”  Non-optimal doesn’t mean wrong  Pointing out opportunities and alternativesMAY 8, 2012 | SLIDE 6

CONTINUOUS INTEGRATION  Team members integrate their work frequently  Each integration is verified by an automated build (including tests)  Goal:  Detect integration errors  As quickly as possible!  Why?  Reduce risks  Deployable software at any timeMAY 8, 2012 | SLIDE 7

(OFTEN) NON-OPTIMAL SETUP  Most commonly encountered approach to CI Developer  Automated Build triggered by VCS VCS  All tests run every single time Build  Eventually someone looks at the CI Tests outcome FeedbackMAY 8, 2012 | SLIDE 8

WHAT IF…  … compilation fails?  Changes already in VCS! Developer  Entire team affected VCS  … a test fails?  Same story! Build  … no one noticed the CI failed?  Kittens die! Tests FeedbackMAY 8, 2012 | SLIDE 9

OPTIMIZE FOR HAPPINESS  Integrate first!  Gated check-ins Developer  Integration fails? Build  Changeset rejected Tests  Integration succeeds?  Changeset committed Feedback Every successful check-in is a reward for good work. VCSMAY 8, 2012 | SLIDE 10

OPTIMIZE FOR QUALITY  Code Analysis Developer Build  Test Impact Analysis Tests Feedback VCSMAY 8, 2012 | SLIDE 11

TFS11 – CI IMPROVEMENTS  Build TriggersMAY 8, 2012 | SLIDE 12

TFS11 – CI IMPROVEMENTS  Supporting multiple test frameworks  MSTest (built-in)  xUnit (http://aka.ms/xunit-vs11)  NUnit (http://aka.ms/nunit-vs11)MAY 8, 2012 | SLIDE 13

VS11 – CI IMPROVEMENTS  Continuously Run Unit Tests  Separate Code Analysis Results windowMAY 8, 2012 | SLIDE 14

VS11 – CI IMPROVEMENTS  Tracking BuildsMAY 8, 2012 | SLIDE 15

VS11 – CI IMPROVEMENTS  Faster Feedback  Dialog Prompt  Auto-Reconciliation  Toast notifications  Improved accessibility to builds  Own recent builds overview  Favorites!  Filter definitions using search boxMAY 8, 2012 | SLIDE 16

TFS ONLINE (BETA)  Built upon Windows Azure  “TFS in the Cloud”  Benefits  Incremental feature upgrades  Reduced timespan between major upgrades  Setup & configuration by Microsoft  Most of internal support & maintenance by Microsoft  Identity management  Via Windows Azure ACS  Only Live ID at the moment  Federation to come?MAY 8, 2012 | SLIDE 17

DEALING WITH DEPENDENCIESMAY 8, 2012 | SLIDE 18

DEPENDENCY HELL “A term for the frustration of software users who have installed software packages which have dependencies on specific versions of other software packages.”MAY 8, 2012 | SLIDE 19

REACTIONS  Reinventing the wheel  We don’t need that dependency  “If they can do it, we can do it, but better”  Marketing-driven versioning  People are waiting for v2 to buy  Let’s call it v7 Platform Update SP3 November Edition KB2348063 RTW Refresh  What happened to reuse of components?  We lost ownership of AssemblyVersion ?MAY 8, 2012 | SLIDE 20

CAUSE AND EFFECT Reference-by-source • “Needed for debugging” syndrome • Found a bug and fixed it • Upgrade path: merges! Reference-by-release • Use symbols for debugging • Report/Fix the bug and submit a pull request • Clean upgrade pathMAY 8, 2012 | SLIDE 21

PACKAGE MANAGEMENTMAY 8, 2012 | SLIDE 22

NUGET  NuGet Gallery  5000+ unique packages  Within “2 clicks or 1 command” reach inside Visual Studio  NuGet improved  Discoverability  Upgrade experience  Reuse of software  Reference-by-release + symbols for everyone  NuGet provides opportunities  Dependency management  Reach, discoverability & visibility of own packagesMAY 8, 2012 | SLIDE 23

VERSIONING  NuGet supports Semantic Versioning  http://www.semver.org Major Breaking changes Minor Backwards compatible API additions/changes Patch Bugfixes not affecting the API  Prerelease  Tags: Alpha, Beta, RC, … (e.g. v1.0.0-RC)  Note: precedence in alphabetic order!MAY 8, 2012 | SLIDE 24

NUGET SUPPORTS SEMANTIC VERSIONING  But not entirely…  NuGet doesn’t support 4th version number (build) for prereleases  1.0.0-RC.32190  Caution: pick a scheme!  Major.Minor.Patch[-Prerelease]  Major.Minor.Patch[.Build]  Workaround:  push CI packages to another feed, e.g. MyGet.org  mark CI packages as prerelease when pushing to NuGet.org – Remove Build number – Append Prerelease tagMAY 8, 2012 | SLIDE 25

DEPENDENCIES VS VCS  In TFS terms: Source Control  Today often contains  Documents  Binaries  Tools  Scripts  Sources  Struggling with binary diffs  Merge conflicts  Repository sizeMAY 8, 2012 | SLIDE 26

PACKAGE REPOSITORY  NuGet Package Repository  Package Restore feature  Opportunity  Get rid of binaries in VCS  Decrease binary diff issues & merge conflicts  Decrease VCS repository size  Manage dependencies centrally  Fine-grained packages = fine-grained dependenciesMAY 8, 2012 | SLIDE 27

IN OR OUT?  Your choice  Have a strategy!  No-Commit?  What if the package source goes down?  What if a package got removed from the repository?  MirroringMAY 8, 2012 | SLIDE 28

Package Restore Package & Symbols Publishing SOLUTION SETUPMAY 8, 2012 | SLIDE 29

DEMO SUMMARY  Enable-PackageRestore  Install-Package NuSpec  Install-NuSpec <project> -EnablePackageBuild  Enable-PackagePush  Set pkg src URL, symbols src URL, API-key  Easy package creation (IntelliSense)  Automatic package building & versioning  Automatic package & symbols pushingMAY 8, 2012 | SLIDE 30
