demo
IntelliTrace Capabilities> Code is instrumented dynamically> Records program execution flow
> Method Enter & Exit> Records program data
> Parameters> Return values
> Low overhead for collection> Supports Dev, Test and Staging
environments> Pay-as-you-go collection model> 1st class debugging experience in VS

Q: Which tests should the developer and tester run to verify this code change?A) Automated Tests
onlyB) Manual Tests onlyC) All of the aboveD) Don’t knowE) Trick question??
Δ
Code Change
Choosing the Right TestsThe ConsequenceThe world of Developers> Run more tests than
needed> Run too few tests than
needed
The world of Testers> Verify more tests than
needed> Verify too few tests than
needed
1. Less Productivity• Effort wasted on tests that don’t need to be
run2. Lower quality• Not enough testing to verify code change
What is Test Impact Analysis?> Automatically pinpoint which tests are
impacted as a result of a code change What is the impact
of this bug fix?

Multi-Tier Performance AnalysisUser: “Why is it taking so long to load the Orders
page?”
Developer: “I wonder where the
problem could be???”

DataTipsPin the DataTip to the source code
DataTip stays in sync with the source code
Toolbar allows the user to pin/unpin a DataTip
Context menu for managing values/expressions in the DataTip
Floating DataTips can be dragged anywhere, and can’t be pinned unless over source code
Space provided for comments in the DataTip which can be collapsed/expanded as desired
DataTip changes color to indicate it is a floating window
