Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.
Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

Seminar on Software Testing
1. 1
SOFTWARE TESTING,
QUALITY CONTROL &
ASSURANCE
SOFTWARE TESTING &
QUALITY CONTROL
• Testing is a process of evaluating a system
by manual or automation means and verify
that it satisfies specified requirements or
identify difference between expected and
actual result.
• Quality provides customer satisfaction for the
first time and every time. It is the factor
affecting an organizations long term
performance and improves productivity and
competitiveness.
2. 2
Why Testing?
• Software testing is important as it may cause
mission failure, impact on operational
performance and reliability if not done
properly.
• Deliver quality software products, satisfy user
requirements, needs and expectation.
• Uncover defects before the products install in
production, it can save a huge loss.
Participants in Testing
• Software Customer
• Software User
• Software Developer
• Tester
• Information Service Management
• Senior Organization Management

Recent Major Computer
System Failure
According to news reports in April’04 a software bug
was determined to be a major contribution to the 2003
Northeast blackout, the worst power system failure in
North American history. The failure involved loss of
electrical power to 50 million customers, forced
shutdown of 100 power plants, and economic losses
estimated at $6 billion. The bug was reportedly in one
utility company’s vendor_supplied power monitoring and
management systems, which was unable to correctly
handle and report on an unusual confluence of initially
localized events. The error was found and corrected
after examining million of lines of code.

5. 5
Testing
• Static (Review)
• Dynamic (Execution)
Static:
• Only review not execution of the program
Dynamic:
• Structural (logic, white box testing, developer)
• Functional (no logic, black box testing, tester)
Structural Testing
• Concerned with testing the implementation of
the program
• Focus on the internal structure of the program
• The intention of structural testing is not to be
exercise all the different I/P or O/P condition
but to exercise the different programming
structure and the data structure of the
program
6. 6
Functional Testing
• Structure of the program is not
considered
• Test cases are decided base on the
requirements or specification of the
program or module
• Hence it is called “Black Box” testing
Some Definition
What is Test Plan?
• Road map for the entire testing activity
What are Test Cases?
• Set of procedures which we execute in our system to
find defects
What is Defects?
• A defect is a variance from a desired product
attributes
• Variance from customer/user expectation
7. 7
Primary Role of Software
Testing
• Determine whether the system meets specification
(Producer View)
• Determine whether the system meets business and
user needs (Customer View)
Role of Tester: Find defect not correcting the defects
Classification of Defects:
• Wrong (ER! = AR)
• Missing (Missing some point)
• Extra (Extra point)
Testing Levels
• Unit Testing
• Integration Testing
• System Testing &
• Application Under Test (AUT) or
User Acceptance Test (UAT)
8. 8
Unit Testing
• LLD
• Module Testing
• Individually Testing
• White Box Testing
• Developer job
• Test each module individually
• Follow White Box Testing (logic of the
program)
Integration Testing
• LLD+ HLD (Developer+ Tester)
• Communication+ Data Flow
• WB+ BB= Gray Box
• Integrate two or more module ie.
Communicate between modules
• Follow a White Box Testing (testing the
codes)
9. 9
System Testing
• Confirms that the system as a whole
delivers the functionality originally
required.
• Follow Black Box Testing
• Functionality Testing, Tester job
User Acceptance Testing
• Building the confidence of the client and
users is the role of the acceptance
testing phase
• It is depend on the business scenario
• Red Box Testing (crucial)
