- Test Driven Development (TDD) uses JUnit to write test cases before writing code to remove fear factors and clearly depict what the code is doing. - The three steps of TDD are Red (a failed test case), Green (the test passes), and Refactor (change code to meet design principles). - An example walks through writing tests for a Book class, making the tests fail, making them pass, and refactoring the code using TDD principles.

Fetal Development!
The document outlines the development of a baby from week 1 through month 9 of pregnancy. In week 1, embryo division begins and the embryo reaches the uterus by day 3. By week 2, the embryo secretes HCG and forms three layers and extraembryonic membranes. Between weeks 3-5, the nervous system appears and organs like the heart, eyes, ears, and limbs start developing. By weeks 6-8, the embryo is recognizably human, and between months 3-4 features like hair, nails, and sex can be determined. From months 5-7, the mother can feel movement and the fetus grows fine hair and protective vernix. In the final months, the fetus further refines its development

Junit
JUnit is a unit testing framework for Java programming language. It was originally written by Kent Beck and Erich Gamma. Some key points:
- JUnit was one of the first unit testing frameworks for Java and has become the de facto standard.
- It allows writing and running repeatable tests to help find and prevent bugs. Tests are written in plain Java classes and methods.
- JUnit provides annotations like @Test, @Before, @After to identify test methods and set up/tear down methods.
- It includes assertions for validations and will report failures immediately. Tests can be organized into test suites.
Introduction to JUnit
This document provides an introduction to JUnit, a unit testing framework for Java. It discusses key concepts like unit testing, test phases (setup, exercise, verify, teardown), test fixtures, JUnit features, annotations like @Test and @Before, assertion statements to validate test results, and best practices for writing unit tests. The goal of JUnit and unit testing is to test code at the component level to find and fix bugs early in the development process.
Unit Testing with JUnit4 by Ravikiran Janardhana
Unit testing with JUnit allows testing individual units of code, especially methods. JUnit provides annotations like @Test to mark test methods and assert methods to validate results. Tests can initialize objects and environment with @Before, validate outputs with assertEquals and other assert methods, and clean up with @After. Multiple test classes can be run together as a test suite with the @RunWith and @SuiteClasses annotations. JUnit is useful for finding bugs, ensuring code works as intended, and allowing test-driven development.
JUnit 5 - The Next Generation of JUnit - Ted's Tool Time

JUnit 4
This document provides an overview of JUnit, a unit testing framework for Java. It discusses how JUnit allows developers to write repeatable tests and test classes in a way that each test can run independently without affecting other tests. The document demonstrates how to write test cases using JUnit annotations and assertions for an AccountService class. It also covers test suites that group multiple test cases, the JUnit testing lifecycle using annotations, and dependencies needed to use JUnit.
Junit and testNG
Unit testing and integration testing are software testing techniques. Unit testing involves validating individual units or components of code work properly. Integration testing involves combining units and testing them together to find interface defects. An example integration test scenario described combining database scripts, application code, and GUI components developed separately into one system and verifying the interfaces. TestNG is a testing framework that supports features like dependency testing, grouping tests, and parameterization to make testing more powerful than JUnit.
JUnit 5 - from Lambda to Alpha and beyond
Want to know what the hype surrounding JUnit 5 is all about? Then join this talk by JUnit 5 core committer Sam Brannen to find out!
Since JUnit 4.0 was first released, a lot has happened in the world of Java. Unfortunately, JUnit 4 hasn't kept up with the times. JUnit 5 therefore aims to help shape the future of testing on the JVM, with a focus on Java 8, modularity, extensibility, and a modern programming API for authoring tests in Java.
This presentation will start off by providing attendees an overview of the inspiration for and architecture of JUnit 5, from launchers to test engines. Sam will then take the audience on an example-driven tour of the new programming model, highlighting support for dependency injection via flexible method signatures, conditional test execution, using lambda expressions and method references in assertions and assumptions, and implementing test/before/after methods via interface default methods.
To round off the discussion, Sam will present an overview of the new extension model in JUnit 5, discussing how to author and register extensions for conditional tests, method parameter resolution, lifecycle callbacks, and more.
Junit 4.0
JUnit is an open source unit testing framework for Java applications. It was written by Erich Gamma and Kent Beck and is part of the xUnit family of unit testing frameworks. JUnit allows developers to write test cases that test individual classes and methods. These test cases can be grouped into test suites and run automatically to ensure code meets requirements and to catch errors early in the development process. JUnit includes annotations like @Test to identify test methods and asserts to validate method output. It integrates with development tools like Eclipse to provide test results.

- Useful resources like sample code from Google are provided to help developers learn Android testing
03 - Prototype Design Pattern - Slideshare.pptx
This document describes the prototype design pattern and provides an example implementation. The key points are:
- The prototype pattern is used to avoid creating multiple objects of the same type by copying (cloning) an existing object instead of creating a new instance.
- An example BookShop class is implemented to store Book objects. Deep cloning is achieved by overriding the clone() method to create a new BookShop instance and copy each Book object rather than just copying the reference.
- This allows modifying one BookShop instance without affecting the other, demonstrating the prototype pattern's ability to create objects independently while sharing initial state.
Functional Programming You Already Know - Kevlin Henney - Codemotion Rome 2015
From JVM to .NET languages, from minor coding idioms to system-level architectures, functional programming is enjoying a long overdue surge in interest. Functional programming is certainly not a new idea and, although not apparently as mainstream as object-oriented and procedural programming, many of its concepts are also more familiar than many programmers believe. This talk examines functional and declarative programming styles from the point of view of coding patterns, little languages and programming techniques already familiar to many programmers.
Microsrvs testing-slides
This document discusses microservice testing strategies and tools. It recommends that developers write unit and integration tests using BDD. QA then performs system integration testing of full flows across environments using different test profiles. Contract testing is used to define producer-consumer contracts and generate tests. Manual testing covers edge cases as the first, middle, and last services in a flow. Various tools are used for local testing, message inspection, performance measurement, and monitoring in production. The overall approach is to automate routine testing, create testing standards, and focus on regression, performance, security and end-to-end testing.

Functional Java 8 in everyday life
The document discusses Java 8 features like lambda expressions, streams, and method references. It provides examples of filtering a list of books by pages or genre using lambda expressions and streams. Lambda expressions allow implementing functional interfaces concisely without anonymous classes. Streams provide a way to process data elements sequentially and support operations like filtering, mapping, matching, reducing, and collecting results.
Uncommon Design Patterns
The document introduces several uncommon design patterns:
1) Null Object pattern avoids using null values by implementing a "null" object that respects the expected interface.
2) Encapsulated Context pattern encapsulates common services/data needed by different components in a single context object rather than using global objects.
3) Role Object pattern handles modeling problems where an element can have different roles by using role objects that are added to and removed from a core object.
4) ISP & Object Adaptation pattern allows objects to adapt to different protocols by checking for direct implementation, using registered adapters, or throwing exceptions.
5) Essence pattern uses an "essence" class to encapsulate an object's configuration and
Ast transformations
This document summarizes various AST transformations in Groovy including local transformations used in Groovy, Grails, and Griffon as well as examples of annotations like @Singleton, @Delegate, @Immutable, @Category, @Mixin, @Grab, @Log, @InheritConstructors, @Canonical, @Scalify, @Entity, @Bindable, @Listener, @EventPublisher, @Scaffold. It also provides a recipe for implementing custom AST transformations with an interface, transformation class, and annotation. Finally it mentions other types of transformations like GContracts, Spock, CodeNarc, and Griffon.
DPC 2019, Amsterdam: Beyond design patterns and principles - writing good OO ...
Of course, you should read all you can about SOLID, Design patterns, Patterns of Enterprise Application Architecture, etc. Once you have a basic understanding of these topics you still have to write that code though, and write it well too! What is good code? Are there some guidelines, or rules of thumb, which you can follow while making your everyday coding decisions?
In this talk I’ll cover many of these coding guidelines, which aren’t usually covered by patterns or principles books. They should help you write better code and give you a richer vocabulary for reviewing other people’s code. Some of the subjects that we’ll discuss are: state, mutability, CQS, one-method objects, domain-first, API-driven, functional programming influences, object boundaries, (de)serialization, and many more!
Javascript
This document provides an overview of JavaScript, including its history, uses, syntax, variables, data types, operators, conditional statements, loops, functions, and ways to display output. Some key points:
- JavaScript is a scripting language used to add interactivity to HTML pages. It was originally developed by Brendan Eich at Netscape under the names Mocha and LiveScript.
- JavaScript code can be embedded within HTML using <script> tags or linked externally via the src attribute. Common uses include form validation, dynamic updating of content, and interactive effects.
- The language supports variables, arrays, objects, numbers, strings, booleans, and other data types. Conditional statements like if

Effective Java with Groovy - How Language Influences Adoption of Good Practices
This document summarizes key points from a presentation about how the Groovy programming language helps developers adopt good practices outlined in Effective Java. It discusses how some Effective Java items like avoiding nulls and enforcing immutability are built into Groovy. AST transformations further reduce work by implementing patterns like the singleton pattern. While Effective Java provides good guidelines, direct implementations may not always apply to Groovy - the language aims to reduce friction to writing good code. Overall, programming languages can help developers implement best practices through built-in functionality and transformations.
Concurrency, Scalability & Fault-tolerance 2.0 with Akka Actors & STM
This document discusses concurrency, scalability, and fault tolerance using actors and software transactional memory (STM) in Akka. It describes how actors provide message-passing concurrency by isolating processes and avoiding shared state. Actors allow easy reasoning about concurrency by preventing issues like race conditions and deadlocks. The document also covers how Akka implements actors, typed actors, remote actors, supervisor hierarchies for fault tolerance, and STM for coordinating concurrent changes to shared state transactionally. Combining actors with STM results in "transactors" that allow building distributed, concurrent, and fault-tolerant applications.
Java design patterns
This document discusses several design patterns: Factory, Flyweight, Singleton, Observer, Proxy, Decorator. It provides definitions and examples of when to use each pattern. The Factory pattern creates objects without specifying the exact class. Flyweight reduces memory usage by sharing instances. Singleton ensures only one instance exists. Observer notifies dependent objects of state changes. Proxy controls access to another object. Decorator adds new behaviors to an object dynamically.
Beyond Design Principles and Patterns
The document discusses object-oriented design principles and patterns. It covers design patterns like abstract factory, mediator, proxy, builder, and others. It also discusses design principles like SOLID principles, package design principles, and tactical domain-driven design patterns. It emphasizes that while knowing patterns and principles is important, the key is applying them correctly. It provides guidance on writing good object-oriented code by focusing on object cohesion, encapsulation, defensive programming, and using composition over inheritance.
Intro to Javascript
JavaScript is the programming language of the web. It can dynamically manipulate HTML content by changing element properties like innerHTML. Functions allow JavaScript code to run in response to events like button clicks or timeouts. JavaScript uses objects and prototypes to define reusable behaviors and properties for objects. It is an important language for web developers to learn alongside HTML and CSS.
C++ interview questions

Significance of private inheritance in C++...
1) Private inheritance in C++ means that the derived class inherits the implementation of the base class but not its interface. The members of the base class become private in the derived class.
2) Private inheritance is useful for the adapter pattern, where the adapter class privately inherits from the adaptee class and publicly inherits from the target class, allowing it to implement the target interface using the adaptee's functions.
3) Unlike public inheritance, objects of a privately derived class cannot be passed to functions expecting the base class, since the derived class is not a subtype of the base class.
Arranging the words of a text lexicographically trie
How can you arrange the words of an input text lexicographically? We can do it using Brute Force method.But is there any other better way? Yes, there are. One such way is by using Trie or Prefix Tree Data Structure. This document shows how to do it using practical code.
Generic asynchronous HTTP utility for android
This is a generic HTTP Asynctsk for Android. It takes care of GET, POSt and PUT and also handles basic authentication.
Copy on write
This document explains the concept of Copy-On-Write (COW) through an implementation of a C++ String class that utilizes COW. It defines a StringHolder class to store the character data and a reference count. The MyString class uses StringHolder and implements copy constructor, assignment operator, and concatenation to share the underlying data and increment the reference count rather than copying until data is modified. This allows efficient memory usage through deferred copying until a string is changed.

Memory layout in C++ vis a-vis polymorphism and padding bits
This document discusses memory layout in C++ with regards to polymorphism and padding bits. It explains that compilers add a virtual pointer (vptr) to objects of classes with virtual functions, which points to a virtual function table (VTABLE). It also discusses how compilers add padding bits to maintain alignment of class members, which can increase the size of objects. As an example, it shows classes A, B and C, and explains through the sizeof outputs how the vptrs and padding bits increase the sizes of objects of these classes for a 64-bit system.

This tutorial shows how to create an Android REST Client and integrates that with Google Map.Observer pattern
1. The document discusses the Observer pattern as implemented in Java through the Observer and Observable classes. The Observer pattern allows objects called observers to monitor changes to other objects called subjects.
2. When a subject's state changes, it notifies its observers. The observers then update themselves to match the new state of the subject. This keeps all observers synchronized with the subject.
3. As an example, the document describes how different views of a document can observe the document object. When the document changes, it notifies the views which then update themselves to reflect the new document state.

The media player framework in Android involves both Java and native C++ code. When a media player is created, the Java code calls native functions that create a corresponding C++ media player object. This native object then interacts with classes like MediaPlayerService and Client to set the data source and start playback. The key steps are the native_setup function creating the native player, setDataSource passing the URI to native code, and MediaPlayerService::create using IMediaPlayerService to get a Client handling playback.

This document describes how we can break a long running background task in an Android service into different states and how we can notify the UI about these states as they proceed., Tackling circular dependency in Java
The document discusses tackling circular dependency in Java code. Circular dependency occurs when class A uses class B, and class B also uses class A, creating a "chicken and egg" problem for the compiler. This is illustrated with a Building class that contains a Lift object, while the Lift class needs information from the Building class. The solution is to define an interface that the Lift class uses instead of directly using the Building class, avoiding the need to initialize Building to create Lift.
Implementation of composite design pattern in android view and widgets
This document describes how the Composite Design Pattern has been implemented in Android View and Widgets.
Exception Handling in the C++ Constructor
This document discusses handling exceptions thrown in C++ constructors. It provides two cases as examples: 1) When an exception is thrown and memory allocated on the stack is destroyed, potentially causing a memory leak. 2) When using smart pointers like shared_ptr avoids this issue by managing memory allocation. The document recommends using smart pointers in modern C++ to prevent memory leaks from exceptions in constructors.
Active object of Symbian in the lights of client server architecture
This document discusses the client-server architecture in Symbian and how it relates to asynchronous functions and the active object framework. It provides an example of using an asynchronous function in a server to read data from a communication port, while allowing the client UI to remain responsive. Code examples are given of a client-server application with an asynchronous function in the server that is called from the client UI using the active object framework. This allows the server function to run asynchronously without blocking the client.
Android services internals
1) When an Android app requests a system service like the PowerManager, it calls the getService() method and passes the service name.
2) getService() returns a handle to the ServiceManager, which it gets by calling getIServiceManager().
3) getIServiceManager() returns a handle to the native ServiceManager that registered itself as the Binder context manager.
4) With the ServiceManager handle, getService() calls the ServiceManager's getService() method, which transacts with the remote native ServiceManager service to retrieve the requested service handle.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
CAKE: Sharing Slices of Confidential Data on Blockchain
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
