The document outlines modern app development practices focused on continuous value delivery, rapid response to change, and agile methodologies. It covers tools and techniques for project management, version control, unit testing, and monitoring applications using Visual Studio and Azure services. Key benefits emphasized include shorter cycle times, enhanced quality through automated testing, and improved user experience through application insights.

Control

29. Strengths Best for
Check-in
Check-out
• Fine level permission control
• Allows usage monitoring
• Large integrated codebases
• Control and auditability over
source code down to the file level
• Offline editing support
• Easy to edit files outside Visual
Studio or Eclipse
• Medium-sized integrated
codebases
• A balance of fine-grained control
with reduced friction
• Fast offline experience
• Complete repository with
portable history
• Flexible advanced branching
model
• Modular codebases
• Integrating with open source
• Highly distributed teams

39.  TDD is a robust way of designing software
components (“units”) interactively so that
their behavior is specified through unit
tests.
 Whenever you are tempted to type
something into a print statement or a
debugger expression, write it as a test
instead.
 Manual or automated testing is much
better for finding bugs.
 Automated integration tests are much
better for detecting regression (things that
used to work but have unexpectedly stopped
working).
[TestMethod]
public void Debit_WithValidAmount_UpdatesBalance()
{
// arrange
double beginningBalance = 11.99;
double debitAmount = 4.55;
double expected = 7.44;
BankAccount account =
new BankAccount("Mr. X", beginningBalance);
// act
account.Debit(debitAmount);
// assert
double actual = account.Balance;
Assert.AreEqual(expected, actual, 0.001,
"Account not debited correctly");
}

40.  Visual Studio Test Explorer is designed to
support developers and teams who
incorporate unit testing in their software
development practices.
 Unit testing helps you ensure the correctness
of your program by verifying that the
application code does what you expect it to
do.
 In unit testing, you analyze the functionality
of your program to discover discrete testable
behaviors that you can test as
individual units.
 You use a unit testing framework to create
tests of those behaviors and to report the
results of those tests.

challenges
Customers desire frequent
updates
Comprehensive manual
testing can impede delivery
speed
Long cycle times result in
increased defects and
decreased quality
Solutions
Reduce scope of feature set
Integrate new features
frequently
Use gated check-in to ensure
unit tests are run
Automate build processes
Minimize code churn after
breakage
Business value
Shorter cycle times lead to
quicker delivery of value
Enforced unit testing
increases quality threshold
Release of quality code
ensures continual value
delivery

47. Continuous integration
automatically creates a
build after check-in
Create multiple build definitions
to support various build scenarios

48. Configure the gated check-in
build to fail if a test fails, ensuring
the code won’t be checked in
Identify specific test to be run
during the gated check-in build

50. Continuous
Deployment
Modern Release
Management

51. Deploying early and often delivers business value fast, generates early
customer feedback and ensures ‘Go Live’ day ends with Champagne
and not a sleepless night

56. Monitoring
Applications

58. Movement to the cloud exacerbates the problem – IT is out of the picture, and the picture is a black
box.

60. User experience is what
ultimately matters

61. Plenty of opportunities for things to go wrong
Mobile app crashed
Server request too slow
Database overloaded
Downstream service down
Feature too hard to use

62. 1. Telemetry is collected at each
tier: Mobile applications, server
applications and browser
2. Telemetry arrives to
Application Insights service
where it is processed & stored
