What is ALM
• According to Wikipedia
– Application lifecycle management (ALM) is
the marriage of business management to
software engineering made possible by tools
that facilitate and integrate requirements
management, architecture, coding, testing,
tracking, and release management.

Defect Tracking and Change
Management
• Defect Tracking is tracking defects (duh) in
a product
– Testing
– Customer Feedback
• Change management
Defect Tracking and Change
Management
• Bugzilla
– Used by Mozilla
– Optimized database structure for increased
performance and scalability
– Built-in security and permissions system
– Advanced query tool that can remember your
searches
– Integrated email capabilities
– Editable user profiles and email preferences

Unit Testing
public static bool AreEqual(byte[] a, byte[] b)
{
if(null == a && null == b) return true;
if(null == a) throw new ArgumentNullException(“a”, “cannot be null”);
if(null == b) throw new ArgumentNullException(“b”, “cannot be null”);
if (a.Length != b.Length) return false;
for(int i=0; i < a.Length; i++)
{
if(a[i] != b[i]) return false;
}
return true;
}
Unit Testing
• You should be Unit Testing!!
• UI’s are more difficult to unit test
• For testing middleware components that
get data from a database you need
– Generate stubs
– Seed data in the database
Unit Testing - Strategies
•
•
•
•
Build tests for each non private method
Each test is independent from other tests
What about private methods?
When building tests make sure to deal
with
– Happy path testing
– Boundary conditions
– Exception cases
Unit Testing
• There are others, but popular ones include
– NUnit
– XUnit
– MbUnit
– CSUnit

Build Management – Build Master
Build Management
• A build is more than just a compile
– Get latest code from source repository
– Compile the code
– Run Unit tests
– Run code analysis / coverage
– Run code compliance
– Deploy to a deployment site if necessary
Build Management Tools
• Nant - useful for performing build tasks
• CruiseControl .Net
– Automated continuous integration server
• Monitors source repository
• On a schedule can launch an integration build to validate
changes
• Notifies developers as to successful build or fail.
• Build is not just a compile of code
• Can build multiple projects on one server
• Remote management and reporting
– CCTray .Net
