The Cost of Sacrificing Quality

− $59 billion in lost productivity in the US

− 64% of this cost is born by “End Users”

− Software bugs account for 55% of all downtime costs

Strategy

Reduce time Unit Testing with Test Impact Analysis & Code Coverage Metrics

Enforce Coding Standards with Code Analysis & Code Metrics

Identify Performance Bottlenecks Before you’re Users with the Performance Wizard

Identify an Application’s limits with the Load Testing Framework

Reduce time Unit Testing with Test Impact Analysis & Code Coverage

Metrics

Unit Test Improvements

Programmatically Control Unit Test Execution

Support for Categories (instead of lists) Performance Improvements Extensible with Custom Attributes Can Extend Unit Test Type Test Generation Test Data Generation

Test Impact Analysis Identifies tests impacted by code changes Significantly reduces test time

Enforce Coding Standards with Code Analysis & Code Metrics

Code Analysis

Process of examining code before runtime to eliminate defects and enforce standards

Code analysis != code review Reduce the man hours spent reviewing

typical coding errors, and spending more time on application design

Dogfooding

Design Globalization Interoperability

Maintainability

Mobility Naming Performance Portability

Reliability Security Usage

Project Health Metrics

“Code metrics provide the ability to dig deep to find those un-maintainable and complex hotspots”

Cyclomatic Complexity Lines of Code Class Coupling Depth of Inheritance Maintainability Index

Identify Performance Bottlenecks Before you’re Users with the

Performance Wizard

Performance Profiling

Measuring the execution of an application Assess your application performance

before deployment Identify & fix those areas that are

performing poorly

Profiling in the CLR

Profiling covers additional monitoring and diagnostics activities to support CLR features Application domains, garbage collection,

managed exception handling, and just-in-time (JIT) compilation

So What’s New?

Tier Interaction Profiling (TIP) – Profile Database Interaction!

Check-in performance reports to use as a baseline for comparison

Capture performance data from automated tests
