5. • Embedded World
• CDC/CLDC and associated JSR’s
• Implementation and extensions
• Compliance Testing
• Usage in applications
• Usability and Extensions
• 3rd party api customization and usage
• Android (SDK)
• JUnit and J2ME Unit and most other extensions
including Mock Testing
• Desktop World
• Ant Customization
• Web 2.0, J2EE Technologies

6. • TejaSoft has experience of seeing/using 100’s of VM
implementations, though our mobile applications
development on various mobile phones.
• We do see Personal Java VM’s would provide different
experience but due to constrained and embedded
nature, we don’t expect too much deviation.
• We have the knowledge base of what kind of issues
with each of the manufactures such as Nokia, Motorola,
Sony Ericsson etc

7. • J2SE and J2ME Profilers
• PMD
• JDepend
• SonarJ

• Structure101

8. In general you could expect the following results on a
Embedded Java Applications .
• At minimum 10% performance increase
• Reduction in code size by at least 10% on a min of
15,000 lines of code
• Reduction in JAR Size and Runtime Memory needs
• Improved Reliability with less crashes
• 10% more reusable code
• At least 15% less if’s in applications
• Positive Code Metric
• For Reduced Dependency
• Reduced Cyclomatic complexity at method levels
• Identify Duplicate Codes
• Few radical suggestions on alternate approaches and
technologies

9. Our association models included
• As a 3rd Party Code Auditors
• As a Test Automation Team
• As a Refactoring Team

10. As a 3rd Party Code Auditors, we provide another view and opinions
which could enable better product evolution and road map.
• We work closely, with Management, Principal
Engineers and Core Developers, hardware and C, C++
teams.
• We understand past development and future needs/goals
• We Observe the current standards and processes of the
development
• We understand the Integration layers and its interfaces
• We understand product versions and variations based on
the similar code base
• We understand the 3rd party products and open source
products dependency

11. • We go though the code on module by module. Most
complex/painful one first
• We apply in-house built and popular tools in this area to
understand and measure the existing code metric and
critical paths
• Following our detailed study we come out with our
observations, doubts and issues at Module, Class, Method,
Relationships and Architecture.
• Based on the client technical team discussions and accepted
points, we suggest a possible road map for changes
• We prefer to do this module by module or application by
application
• Time span for this kind of engagement could be any where
between 8 to 10 weeks

12. As Test Automation Team we give a safety net for your embedded applications
• Our focus would be writing the unit, load and performance test
suites for the existing code base of CDC/STB applications and VM
API Implementations.
• We may also decide to write functional test cases and move towards
unit tests.
• We work with developers and architect in case code needs to be
refactoring for better testability
• We follow the code coverage and good principles of test case
writing for easy and suite level running of the same by developers
and build system.
• We have expertise to build test cases from zero to 20,000+ tests
which just take 10 minutes to test a module. Before this approach it
was taking two weeks (Manual testing)

13. As Refactoring Team, we give green code and new fresh life next release
• This is recommended approach once we complete the cycle as a
3rd party audit team and Test Automation team. However it is not a
compulsion.
• By which time, we would have know the product and people and
process
• We agree upon Refactoring goals in terms of code reduction,
complexity reduction and time frames.
• We take the code and refactoring ownership and deliver the results
• We may write test cases based on backward compatibility needs
• We have expertise to convert more than 25000 lines of code in just
5 classes to 200 plus classes (including the test cases) and each
class not being more than 200 lines.

14. • Internet Profile and Search
• www.linkedin.com/in/nagkumar
• My customers and colleagues feedback
• Raja Nagendra Kumar on google or Respective
