Automatically Repairing Test Cases for Evolving Method DeclarationsICSM 2010
TestCareAssistant is a tool that can automatically repair unit tests that fail to compile due to changes in method declarations. It repairs compilation errors by making changes like modifying parameter types, adding or removing parameters, or changing return types. The tool was able to automatically repair 72% of tests cases, 75% of compilation errors, and initialize parameter values correctly in 80% of cases across several open source projects. However, static data flow analysis is not always effective for repairing tests that use complex data structures.
“Program to an interface, not an implementation” they[1] say …
But when IMyInterface foo = new IMyInterface() is not valid code … how are you supposed to achieve that ? The answer is Dependency Injection.
In this talk, we’ll talk about Dependency injection, what it is and what it is not. We’ll see how it is a valuable set of practices and patterns that help design maintainable software built on top of the SOLID object-oriented principles.
We’ll see how, when used properly, it delivers many benefits such as extensibility and testability … We’ll also cover some anti-patterns, ways of using Dependency Injection that can lead to code that is painful to understand and maintain
This talk is not about DI/IOC containers per se, but focuses on the core concepts of Dependency Injection. Those concepts are essential to understand how to use those “magic-looking” tools (if they are needed at all …)
This talk is not only for .NET developers. It will contain code examples written in C#, but should be understandable by developers with knowledge in other statically-typed object-oriented languages such as Java, Vb.NET, C++ …
The document provides examples of code snippets and design principles for building banking applications. Some key points discussed include:
- Encapsulating state checks and validation logic rather than exposing primitive checks.
- Avoiding mutable collections and exposing only immutable views of data.
- Modeling domain-specific concepts like transactions, accounts, customers rather than using language primitives.
- Implementing single responsibility and telling objects what to do rather than how to do through dependency injection.
The examples demonstrate applying object-oriented design principles like encapsulation, single responsibility and dependency injection to model complex domain concepts in banking applications.
The decorator pattern allows extending the functionality of an sObject in Apex without modifying the sObject itself. The code samples demonstrate decorating a Weather sObject to allow bidirectional conversion and display of temperature between Fahrenheit and Celsius. A DecoratedWeather class wraps the sObject and handles the conversion logic. The Visualforce controller uses this decorated class to display and update temperature values while insulating the UI from conversion details.
The document discusses various refactoring techniques that can be used with Java's functional API. It begins with an introduction to refactoring and covers catalog of refactorings including composing rules with predicates, using optionals appropriately, inverting dependencies with suppliers, and writing idiomatic functions. Examples are provided for each technique to demonstrate refactoring code to improve design, readability, and reduce technical debt. References for further reading on refactoring and software design are also included.
The document discusses the importance of unit testing and describes how developers are returning to write good tests after cutting corners during economic difficulties. It provides examples of unit tests being written for an order management system using PHPUnit to test the createOrder method by mocking dependencies and asserting the return value.

SummaryHW6 Account ManagementIn HW4, you kept track of multiple.pdfARORACOCKERY2111
Summary
HW6: Account Management
In HW4, you kept track of multiple usernames and its associated password using arrays.
However, usernames and passwords are typically part of a “User” object which in turn may be
part of an “Account” object. Accounts also typically require a certain level of security beyond
the typical encryption mechanisms. This assignment goes deeper into the concept of OOP as you
create objects that requires proper rules and scope for correct usage.
Aside: As with Item objects from HW5, Account and User data is typically stored in databases.
Skills Expected
? All the skills from previous Assignment(s)
? Accessors/Mutators
? Overriding methods: equals and toString
Assignment Description
You will write three Class objects and a Driver for each class (i.e. submit six .java files):
? User
? Account
? AccountList
Note: All properties MUST be private
Submission Requirement: The Driver Class
? Each Class designed MUST be submitted with a corresponding “Driver” Class
? The Driver Class should have a main() that demonstrates, at minimum
o Calling the appropriate constructor to create the appropriate instance
o Everyproperty(instancevariables)canbesetandgetcorrectly(whereallowed) ? Every public
method can be called successfully (and return the correct result)
Class Design: User
The User class is intended to be an abstract and simplified representation of a user
Class Properties
? First Name (String)
? Last Name (String)
? Username (String)
? Password (String)
Class Invariant
? First and Last Name must not be empty
? Username must be at least four characters long
? Password must be at least four characters long (is this a good invariant?)
Class Components
? A constructor that sets the initial user data (first name, last name, username, password)
? A getter/setter for each properties set out above
? A toString() method
? An equals() method
Class Design: Account
The Account class is intended to be an abstract and simplified representation of an account
Class Properties
? User (User)
? Balance (double) – represents how much money the user has in the account
Class Invariant
? Must be a valid account
? Balance must not be negative
Class Components
? A constructor that sets the initial User instance and balance amount
? A Getter but not a Setter for the each properties set out above (why?)
? A public method to add to the balance
? A public method to withdraw from the balance
? A toString() method
? An equals() method
Class Design: AccountList
The AccountList class is intended to be an abstract and simplified representation of a list of
accounts.
Class Properties
? Accounts (an array of Account objects – or ArrayList) o No getters or setters* (do you know
why?)
Class Invariant
? Can’t have multiple accounts with the same username
Class Components
? A public method that adds new accounts
? A public (boolean) method that determines whether an account with a given username exists in
the list
Grading Criteria
? User class object
o [2 points] Impl.
This document discusses best practices for writing clean tests, including naming conventions, test structure, and principles such as keeping tests focused on individual behaviors, avoiding logic in tests, and preferring to test public APIs over private methods. It recommends giving tests clear and descriptive names, using a Given-When-Then structure, and creating reusable helper functions to prepare test data. Tests should have a single assert per scenario and verify only the relevant method arguments for the behavior being tested. Following these guidelines helps produce tests that are easy to understand and maintain.
Tests should save our money and time. How is it that they often become the stumbling block and slow down the work? They fail every time you try to do some refactoring and are difficult to maintain ultimately increasing the cost of software maintenance. If you have such problems it means that you may have gone "a mock too far " - testing the wrong things, and you using mock in the wrong places.
Examples how to test different types of code wisely so tests will protect your application and will not be a burden for you.
This document discusses how JavaScript code would look if Java was written in JavaScript. It provides examples of Java-like classes and methods written in JavaScript. It also discusses JavaScript design patterns like the Module pattern and MVC frameworks. Finally, it covers topics like unit testing JavaScript with Jasmine, SVG vs Canvas for graphs, and libraries like Underscore.js and CSS frameworks.

Use the Account class created in Programming Exercise 9.7 to simulate an ATM machine.
Create ten accounts in an array with id 0, 1, . . . , 9, and initial balance $100.
The system prompts the user to enter an id. If the id is entered incorrectly, ask the user to enter a
correct id.
Once an id is accepted, the main menu is displayed as shown in the sample run.
You can enter a choice 1 for viewing the current balance, 2 for withdrawing money, 3 for
depositing money, and 4 for exiting the main menu.
Once you exit, the system will prompt for an id again. Thus, once the system starts, it will not
stop.

The document discusses different approaches to unit testing object-oriented code using mocks and stubs. It argues that mocks are better suited for testing incoming queries by asserting on results, while stubs are better for outgoing queries to avoid asserting on mocks. For testing commands, it is better to assert on state changes or side effects rather than messages to mocks. The example of testing a prepaid topup service demonstrates asserting on the side effect of orders placed rather than messages to a mock.
This document provides an overview of the Java Persistence API (JPA) including entity classes, managing entities, persisting entity instances, and primary keys.
Some key points covered are:
- Entity classes represent tables in a database and have requirements like the @Entity annotation and a no-arg constructor.
- Entities are managed by an EntityManager which performs CRUD operations and runs queries.
- To persist a new entity, the persist method is called on the entity manager.
- Primary keys can be simple or composite. Simple keys use @Id while composite keys use @IdClass or embed the key class with @EmbeddedId.
The document discusses object oriented programming concepts in C++. It contains 4 questions with solutions. Question 1 defines a BankAccount class with data members like name, account number etc. and member functions to assign values, deposit, withdraw amounts. Question 2 overloads the increment operator ++. Question 3 overloads the > operator to find greater of two class instances. Question 4 demonstrates single and multiple inheritance - single inheritance defines a PhysicalFit class derived from BasicInfo class, multiple inheritance defines a DerivedD class derived from 3 base classes.
JQuery is awesome, but with all major browsers following the ES and HTML5 specs, the library has become more of a convenience than a necessity for browser compatibility. While the library is useful and ubiquitous, it does distract us from learning the language that it's built on. This talk will outline functionalities that pure javascript provides, and also provide steps we can take to begin writing vanilla javascript applications and start appreciating the power and uniqueness of javascript.

Use the Account class created in Programming Exercise 9.7 to simulate an ATM machine.
Create ten accounts in an array with id 0, 1, . . . , 9, and initial balance $100. The system prompts
the user to enter an id. If the id is entered incorrectly, ask the user to enter a correct id. Once an
id is accepted, the main menu is displayed as shown in the sample run. You can enter a choice 1
for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for
exiting the main menu. Once you exit, the system will prompt for an id again. Thus, once the
system starts, it will not stop. You will need to cntrl-c to stop your program; this is ok for this
assignment. If you want your program to terminate more elegantly you can add in additional
logic, but this is not required.

Developing A Real World Logistic Application With Oracle Application - UKOUG ...Roel Hartman
This document summarizes the development of a real-world logistic application using Oracle Application Express (APEX) for a client. It describes enhancing the existing application by replacing forms with APEX, including adding direct validation, replacing the calendar with jQuery, showing descriptions for codes, and improving the list of values functionality. The presentation provides examples of implementing these enhancements in APEX.
The most massive crime of identity theft in history was perpetrated in 2007 by exploiting an SQL Injection vulnerability. This issue is one of the most common and most serious threats to web application security. In this presentation, you'll see some common myths busted and you'll get a better understanding of defending against SQL injection.
This document discusses the history of computing and programming languages. It notes that many revolutionary ideas from the past are not yet common, such as treating code as objects and dynamic programs that can change as they run. The document advocates learning from the past by reading seminal works and learning languages like Lisp, Smalltalk, and Self to challenge current assumptions. Understanding our history can help us avoid reinventing solutions and using better approaches.
The document appears to be a presentation about the CodeIgniter PHP framework. It discusses concepts like MVC, fat models/skinny controllers, validation, auto-loading views, and using presenters. It advocates for convention over configuration and processing data in the model. The presentation promotes CodeIgniter's flexibility and adaptability compared to other frameworks.
What AI Means For Your Product Strategy And What To Do About ItVMware Tanzu
The document summarizes Matthew Quinn's presentation on "What AI Means For Your Product Strategy And What To Do About It" at Denver Startup Week 2023. The presentation discusses how generative AI could impact product strategies by potentially solving problems companies have ignored or allowing competitors to create new solutions. Quinn advises product teams to evaluate their strategies and roadmaps, ensure they understand user needs, and consider how AI may change the problems being addressed. He provides examples of how AI could influence product development for apps in home organization and solar sales. Quinn concludes by urging attendees not to ignore AI's potential impacts and to have hard conversations about emerging threats and opportunities.

I made this Account.java below. Using the attached code I need help with 10.7 (Game: ATM
machine)
Use the Account class created in Programming Exercise 9.7 to simulate an ATM machine.
Create ten accounts in an array with id 0, 1, . . . , 9, and initial balance $100.
The system prompts the user to enter an id. If the id is entered incorrectly, ask the user to enter a
correct id.
Once an id is accepted, the main menu is displayed as shown in the sample run.
You can enter a choice 1 for viewing the current balance, 2 for withdrawing money, 3 for
depositing money, and 4 for exiting the main menu.
Once you exit, the system will prompt for an id again. Thus, once the system starts, it will not
stop.

Bank Program in Java
Below is my code(haven\'t finished, but it be run without error messages.)
My problem is in Case 1. For example, if I enter two customers:
Name: John Kangas Account Number: A123 Balance: 300
Name: Mary White Account Number: B321 Balance: 600
In the output -- For testing, I expected it to be like this:
***For Testing!
John Kangas
Balance: 300.0
****
***For Testing!
Mary White
Balance: 600.0
****
However, it actually came out like this:
***For Testing!
Mary White
Balance: 600.0
****
***For Testing!
Mary White
Balance: 600.0
****
It seems that the second information replace the first one. Could anyone help me figure it out??
Thank you so much!!

The document discusses different approaches to unit testing object-oriented code using mocks and stubs. It argues that mocks are better suited for testing incoming queries by asserting on results, while stubs are better for outgoing queries to avoid asserting on mocks. For testing commands, it is better to assert on state changes or side effects rather than messages to mocks. The example of testing a prepaid topup service demonstrates asserting on the side effect of orders placed rather than messages to a mock.
This document provides an overview of the Java Persistence API (JPA) including entity classes, managing entities, persisting entity instances, and primary keys.
Some key points covered are:
- Entity classes represent tables in a database and have requirements like the @Entity annotation and a no-arg constructor.
- Entities are managed by an EntityManager which performs CRUD operations and runs queries.
- To persist a new entity, the persist method is called on the entity manager.
- Primary keys can be simple or composite. Simple keys use @Id while composite keys use @IdClass or embed the key class with @EmbeddedId.
The document discusses object oriented programming concepts in C++. It contains 4 questions with solutions. Question 1 defines a BankAccount class with data members like name, account number etc. and member functions to assign values, deposit, withdraw amounts. Question 2 overloads the increment operator ++. Question 3 overloads the > operator to find greater of two class instances. Question 4 demonstrates single and multiple inheritance - single inheritance defines a PhysicalFit class derived from BasicInfo class, multiple inheritance defines a DerivedD class derived from 3 base classes.
JQuery is awesome, but with all major browsers following the ES and HTML5 specs, the library has become more of a convenience than a necessity for browser compatibility. While the library is useful and ubiquitous, it does distract us from learning the language that it's built on. This talk will outline functionalities that pure javascript provides, and also provide steps we can take to begin writing vanilla javascript applications and start appreciating the power and uniqueness of javascript.

I need help creating a basic and simple Java program. Here is the exercise. I have included my
Account class that is referred to at the bottom, below the exercise.
Use the Account class created in Programming Exercise 9.7 to simulate an ATM machine.
Create ten accounts in an array with id 0, 1, . . . , 9, and initial balance $100. The system prompts
the user to enter an id. If the id is entered incorrectly, ask the user to enter a correct id. Once an
id is accepted, the main menu is displayed as shown in the sample run. You can enter a choice 1
for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for
exiting the main menu. Once you exit, the system will prompt for an id again. Thus, once the
system starts, it will not stop. You will need to cntrl-c to stop your program; this is ok for this
assignment. If you want your program to terminate more elegantly you can add in additional
logic, but this is not required.
Please refer to textbook for sample output pg. 401.

The most massive crime of identity theft in history was perpetrated in 2007 by exploiting an SQL Injection vulnerability. This issue is one of the most common and most serious threats to web application security. In this presentation, you'll see some common myths busted and you'll get a better understanding of defending against SQL injection.
This document discusses the history of computing and programming languages. It notes that many revolutionary ideas from the past are not yet common, such as treating code as objects and dynamic programs that can change as they run. The document advocates learning from the past by reading seminal works and learning languages like Lisp, Smalltalk, and Self to challenge current assumptions. Understanding our history can help us avoid reinventing solutions and using better approaches.
The document appears to be a presentation about the CodeIgniter PHP framework. It discusses concepts like MVC, fat models/skinny controllers, validation, auto-loading views, and using presenters. It advocates for convention over configuration and processing data in the model. The presentation promotes CodeIgniter's flexibility and adaptability compared to other frameworks.

Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/
Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.
