Goals


Build, Test, and Deploy Your App
The Application
– Test Driven Development / Unit Tests
– ASP.NET
– WCF hosted in IIS
Why automated builds?



Repeatability
Did I mention repeatability?
Eliminate the “works on my box” problem
Demo 1


Tour of the app
Add it to TFS source control
Why Continuous Integration?





Eliminate painful integration
Catch bugs early
(Theoretically) ship immediately
Code always builds
Tests always pass
Demo 2




Create the Team Build
Run the tests from the build
Configure Continuous Integration
Run the build
3rd Party MSBuild Tasks



Saves you time/effort
Free
MSBuild Community Tasks
– http://msbuildtasks.tigris.org/
– IIS Configuration tasks

SDC Tasks
– http://www.codeplex.com/sdctasks
– Microsoft Virtual Server 2005 R2 tasks
Build is failing



IIS isn’t configured
Best practice: delete and recreate IIS virtual
directories
Ensures…
– …a clean environment
– …you’re testing the right version
– …you know how to configure your app
Demo 3

Configure IIS in the BeforeTest target
KICKING IT OVER THE
WALL
Move code between environments


How would you get the current version to
QA?
QA can’t test against continuous integration
– Needs a stable code base version to test against
QA Test Environment

Use Virtual Machines
– Cheap
– Hyper-V or Virtual Server 2005 R2


Create template machines with SysPrep.exe
Configure the machines then Enable Undo
Disks
– Easy rollback to completely clean, known state
– Fresh state  you know how to config your app
How do you get the code to QA?




Need a good way to get it there
Need a good way to configure it
Worst-practice: humans configure the app
Best-practice: automated configuration
– Automatic deploy, config = great documentation

Create an MSI installer using WiX
WIX
What does an installer do for you?








Install & Uninstall
Registry keys
Folder paths
COM registration
Update logic
Program menu shortcuts
Way too hard for a non-technical user
Non-repeatable without an automated
installer
What is WiX?



Windows Installer Xml
Xml to describe Windows Installer MSI’s
Developed by Microsoft
– Around 1999


Released to Open Source in April 2004
Mostly written by Rob Mensching


http://wix.sourceforge.net/
WiX is not dead




Sourceforge site has spotty updates
Weekly drops are still getting made
http://wix.sourceforge.net/releases/
Visual Studio setup is written in WiX
WiX will be included as a project type in
VS2010
How do you get started?


Go to http://wix.sourceforge.net/releases/
Download & install the latest 3.0.* release
WiX Projects in Visual Studio

“Votive”
Votive Projects





Allow you to add, edit
Intellisense
Compiler support
Defines variables to reference solution/project
paths
Source control
Votive Project Types

WiX Project
– Generates *.msi

WiX Merge Module
– Installer referenced from another installer
– Generates *.msm

WiX Library Project
– Re-usable pieces of WiX

WiX Custom Action
– Extend the installer logic
Other tools that comes with WiX

Heat.exe
– Jump starts WiX creation

Candle.exe
– WiX Compiler

Light.exe
– WiX Linker

Dark.exe
– Decompiler

Smoke.exe
– Validator
Basic WiX Elements








<Wix> - Root element w/ Namespaces
<Product> - What you’re installing
<Directory>, <File>
<Feature>, <Component>
<UI>, <Dialog>
<Fragment>
<Property>
“Refs”
Defining the user interface

<UI>
– Defines user interface features

<UIRef Id=“ui_name”>
– Reference a UI

WixUIExtension.dll
– Pre-defined UI Sequences
– WixUI_Mondo, WixUI_Advanced, WixUI_FeatureTree,
WixUI_InstallDir, WixUI_Minimal

Decent documentation at
http://www.wixwiki.com
Installing Web Apps

Use heat.exe to start
– HINT: don’t bother with the “website” option




Edit the directory references
Add reference to WixIisExtension.dll
Point <iis:WebVirtualDir>
Set <iis:WebApplication>
Tips for Deploying Web Apps

Put each app in a separate wxs file
– IIS Service Host
– Web UI
– Admin Web UI

During Dev/QA, use WiX to simplify
deployment of releases
– Generate and build WiX during TFS Team Build
– Use <Target Name=“AfterCompile”> or
<Target Name=“PackageBinaries”>
Best Practice

Set Id=“*”
– Auto generates a new id on compile

Never change your upgrade code
Demo 4




Create the WiX Installer
Install the app
Configure IIS
Run the build  MSI
MSIExec From the Command Line

Msiexec installer.msi
– /i – install
– /u – uninstall
– /L filename – specify a log file
– /qn – silent

Pass parameters in using
– MY_PARAMETER=value

Control feature installation
– ADDLOCAL=ProductFeature,ProductFeature2
A MORE COMPLEX
ENVIRONMENT
Deploying to other machines



What if you need to deploy to other machines
in order to test?
Deploy the WCF service to another box before
running tests
Environment specific configurations in the
WiX
Fancy.







Compile
Create the installer
Start virtual machines from Team Build
Copy the installer to the VMs
Run the installer
Run tests against the running WCF app
Tear down the VMs
Control VMs from Team Build


Start / Stop Virtual Server 2005 R2 machines
Use the SDC Tasks
http://www.codeplex.com/sdctasks
The VirtualMachine Tasks
<Import Project="$(MSBuildExtensionsPath)\
SDCTasks\Microsoft.Sdc.Common.tasks" />
<VirtualServer.VirtualMachine.Start
ServerName=“virtualServerName"
MachineName=“virtualMachineName"
Timeout="20“ />
<VirtualServer.VirtualMachine.Stop … >
Demo 5






Start a virtual machine
Wait for it to start
Copy the MSI
Install the MSI
Run the tests
Stop the virtual machine
Summary


Running app with unit tests
App compiled by Team Build
Team Build configures the app
WiX to create the installer
Installer from the build that we can hand off
to QA
Start virtual machines
Copy / Run installer
Run tests using the VM
