What is DevOps?

According to DevoPedia, “DevOps is

the coming together of both

development and operations teams into

a coordinated workflow such that

collaboration and productivity are

improved to meet shared business

goals. Building on Agile and

Lean, DevOps enables the business to

respond to changes and meet customer

needs faster. Tools and automation are

necessary enablers. Practices such as

Continuous Integration and Continuous

Delivery are often followed.”

Test Driven Development (TDD)

TDD





GPDIS_2018.ppt | 9

TDD Cont.

• Works well with Agile teams

and short development cycles

• Keep the unit or module small

• Steps

• Write the test first

• Write only the code that is

needed to pass the test

• Refactor to organize and

eliminate duplication

• Repeat

• Focus on software quality

• Avoid building dependencies

between test cases

GPDIS_2018.ppt | 11

Benefits and Limitations of TDD

• Benefits• Develop code that reflects new business requirements

• Higher productivity by focusing on one test at a time

• Tidier and higher quality code

• Helps keep unused code out of the system

• Built-in regression testing as part of a Continuous

Integration process

• Fewer bugs

• Living documentation

• Limitations• Requires time and effort up front

• Difficult to write good test cases

• Takes time maintain test suites

GPDIS_2018.ppt | 14

CI – Source Control

Source code is

structured so each

release is branched

and maintains it’s

own history.





GPDIS_2018.ppt | 15

CI – Cruise Control

CCNet polls for changes every

5 minutes. If a change is found

it will wait an additional 5

minutes of inactivity before

starting a build.





GPDIS_2018.ppt | 16

CI – Label, Get, and Compile Code

NAnt script is run to

label the “build”

directory in source

control with the build

number (e.g. 9.1.0.538)

Compiled code results

for all projects in the

solution on the build

machine.





GPDIS_2018.ppt | 17

Static Code Analysis (SCA)

SCA





GPDIS_2018.ppt | 18

SCA - SonarQube

SonarQube is used to

scan the code to

check for good coding

practices.





GPDIS_2018.ppt | 19

SCA - Fortify

Fortify is used to check

code for good security

practices.





GPDIS_2018.ppt | 20

Functional Testing

Functional Testing





GPDIS_2018.ppt | 21

Functional Testing Cont.

Scripts are

automatically run to

create Oracle and

SQL Server unit test

databases.

Tables and Indexes

with bootstrap data

are created along with

procedures, views,

sequences, etc.

Unit test startup, execute,

and teardown is recorded

in the build log.
