This document discusses strategies for gaining confidence in applications and systems. It begins by defining what is meant by "gaining confidence" and why it is important. It then outlines several topics to be covered, including using language paradigms like imperative, object-oriented, and functional programming to perform static and dynamic analysis. It will discuss testing at different levels from unit tests up to integration and system-level tests. It will also look at simulation testing to analyze emergent behaviors and how monitoring in production helps continue analysis.

Make the Most of Your Time: How Should the Analyst Work with Automated Tracea...
The document discusses requirements traceability and how analysts can work efficiently with automated traceability tools. It presents the results of two experimental studies that evaluated the impact of different analyst behaviors - including with/without feedback and global vs local ordering - on precision, recall, and effort when developing requirements traceability matrices. The most efficient behaviors were local ordering with feedback, as they resulted in the highest precision and recall while examining the fewest candidate links.
Code Ownership and Software Quality: A Replication Study @ MSR 2015
In a traditional sense, ownership determines rights and duties in regard to an object, for example a property. The owner of source code usually refers to the person that invented the code. However, larger code artifacts, such as files, are usually composed by multiple engineers contributing to the entity over time through a series of changes. Frequently, the person with the highest contribution, e.g. the most number of code changes, is defined as the code owner and takes responsibility for it. Thus, code ownership relates to the knowledge engineers have about code. Lacking responsibility and knowledge about code can reduce code quality. In an earlier study, Bird et al. [1] showed that Windows binaries that lacked clear code ownership were more likely to be defect prone. However recommendations for large artifacts such as binaries are usually not actionable. E.g. changing the concept of binaries and refactoring them to ensure strong ownership would violate system architecture principles. A recent replication study by Foucault et al. [2] on open source software replicate the original results and lead to doubts about the general concept of ownership impacting code quality. In this paper, we replicated and extended the previous two ownership studies [1, 2] and reflect on their findings. Further, we define several new ownership metrics to investigate the dependency between ownership and code quality on file and directory level for 4 major Microsoft products. The results confirm the original findings by Bird et al. [1] that code ownership correlates with code quality. Using new and refined code ownership metrics we were able to classify source files that contained at least one bug with a median precision of 0.74 and a median recall of 0.38. On directory level, we achieve a precision of 0.76 and a recall of 0.60.
Lecture 1
Formal methods involve mathematically-based techniques for specifying, developing, and verifying software and hardware systems. They use formal languages and logic to create unambiguous and precise descriptions that can be analyzed for consistency and correctness. Formal methods can be applied at different levels of rigor, from using some mathematical notation in English specifications to fully formal machine-checked proofs. While useful for complex, safety-critical systems, formal methods need not be applied to every component or phase of development in order to provide benefits like error detection.

It also lists attributes of good tests, including being specific, traceable, self-contained, predictable, and clear. Finally, it outlines challenges to test automation, such as changing requirements, outages, technical debt, and unknown dependencies.
Experiments on Design Pattern Discovery
The document describes experiments conducted to discover design patterns from source code. It outlines the approach taken by DP-Miner tool, presents experiment data on four Java systems, and evaluates results by calculating precision and recall values. Benchmarks are lacking for accurately evaluating design pattern discovery techniques.
Technology Roundup - Programming Languages & Paradigms
At Acism, we often found new joinees lacking a good perspective on the software technology. The software technology was shaped not only through genius minds at work but also through business interests. For students and professionals aspiring to work in the technology area, it is crucial to understand this phenomena. This understanding enables them to understand better where the various programming languages are coming from, and also to create the right expectation of what to expect from a given language, given its classification. Therefore, for Acism's new joinees, we often cover this as a part of induction.
When invited to give a tech talk at a PMI meet, we thought about sharing this understanding with the software project manager audience. For this talk, we attempted to capture this understanding in the slideshare. The talk was well-appreciated. The slideshare is shared below.

Just Enough (Automated) Testing
The challenge for every product is to ship bug-free code as often as possible. Whether you are an early stage startup with a pilot application or a large corporation with myriad services, you’re dealing with this problem every day.
We usually end up with either too little or too much testing and it’s hard to find the sweet spot. Too little testing and you have bugs and application instability, leading to time spent fixing bugs and manually regression testing your apps. You’re asking yourself, “isn’t there an easier way to do this?” Too much testing and you have slow release times and high automation maintenance costs. In this scenario, you’re asking yourself, “are the bugs I’m catching worth the time I’m spending maintaining this code?”
In this webinar, software engineer Kate Green will go over a framework for evaluating your testing situation in order to find your organization’s sweet spot.
Key Takeaways
- Understanding where you are today
- Identifying weak, brittle, or buggy parts of your application
- Figuring out where to test first, and with what types of tests
- How to pare down an excessively large automation suite

Kasper Hanselman - Imagination is More Important Than Knowledge
The document discusses the need for software testing to adapt to today's complex, networked world. It argues that most testing still focuses on structured functional testing as if for standalone software, rather than integrated systems. It recommends that testers specialize in areas like usability, security, and gain domain expertise. Testers need to be flexible and creative in their approaches. The testing process also needs to align more with project management methods and tools to effectively deliver results.

System testing
System testing evaluates a complete integrated system to determine if it meets specified requirements. It tests both functional and non-functional requirements. Functional requirements include business rules, transactions, authentication, and external interfaces. Non-functional requirements include performance, reliability, security, and usability. There are different types of system testing, including black box testing which tests functionality without knowledge of internal structure, white box testing which tests internal structures, and gray box testing which is a combination. Input, installation, graphical user interface, and regression testing are examples of different types of system testing.

Software Testing
The document discusses testing for various types of software applications and systems. It covers testing for object oriented applications, internal controls, commercial off-the-shelf (COTS) software, and client-server systems. Specific topics mentioned include object oriented testing techniques, testing of transaction processing and security controls, challenges in testing COTS software, and approaches for client-server testing.
Testing 2 - Thinking Like A Tester
The document discusses various techniques for testing software such as black box testing, white box testing, coverage-based testing, model-based testing, property-based testing, and agile testing. It provides details on different types of coverage like code coverage, data coverage, and model-based coverage. It also describes different testing techniques like equivalence partitioning, input domain testing, and syntax generation that can be used with model-based testing. The document emphasizes applying critical thinking skills to testing and considering different perspectives.
Characterization of Open-Source Applications and Test Suites
Software systems that meet the stakeholders needs and expectations is the ultimate objective of the software
provider. Software testing is a critical phase in the software development lifecycle that is used to evaluate
the software. Tests can be written by the testers or the automatic test generators in many different ways and
with different goals. Yet, there is a lack of well-defined guidelines or a methodology to direct the testers to
write tests
We want to understand how tests are written and why they may have been written that way. This work is a characterization study aimed at recognizing the factors that may have influenced the development of the test suite. We found that increasing the coverage of the test suites for applications with at least 500 test
cases can make the test suites more costly. The correlation coeffieicent obtained was 0.543. The study also found that there is a positive correlation between the mutation score and the coverage score.
Unit test Android
Unit testing validates that individual software units perform as designed. Integration testing exposes faults in interactions between integrated units. System testing evaluates a complete system's compliance with requirements. Acceptance testing assesses if a system is acceptable for delivery and meets business needs.

It provides details on each type of testing, including definitions and the pros and cons of functionality testing specifically. The key methodologies covered are functionality testing, which validates outputs against expected outputs; performance testing, which evaluates a system under pressure; and usability testing, which tests the user-friendliness of an application.
Formal Specification Ian Sommerville 9th Edition
The document discusses formal specification methods in software engineering. It describes formal specification as a way to represent software using mathematical concepts like logic and set theory. While formal methods were proposed in the 1980s to improve quality, they have seen limited industrial use due to costs and market pressures favoring rapid development over quality. The document outlines how formal specification fits into the software process and describes algebraic and model-based approaches. It provides an example of formally specifying an insulin pump system using Z notation.

- Writing automated tests takes a significant amount of time and effort, often resulting in test code that is twice or three times the size of the actual code being tested. This occurs because tests are written in isolation and dependencies must be mocked.
- A better approach is to write tests that focus on behaviors and public interfaces rather than implementation details. Tests should not break when implementation details change, only when public behaviors change. This allows for easier refactoring of code without breaking tests.
- Rather than focusing solely on unit tests, more effort should be put into system level testing which typically finds twice as many bugs. Tests can also be improved by designing them more formally and moving assertions directly into the code being tested.
testing
The document discusses various concepts related to software errors, faults, failures, and testing. It defines that an error is made during development, a fault is the manifestation of an error in the code, and a failure occurs when the fault is triggered. Testing involves exercising the software with test cases to find failures or demonstrate correct execution. There are two main approaches to identifying test cases - functional testing based on specifications and structural testing based on code. Both approaches are needed to fully test the software.

“Temporal Event Neural Networks: A More Efficient Alternative to the Transfor...Edge AI and Vision Alliance
For the full video of this presentation, please visit: https://www.edge-ai-vision.com/2024/06/temporal-event-neural-networks-a-more-efficient-alternative-to-the-transformer-a-presentation-from-brainchip/
Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

High performance Serverless Java on AWS- GoTo Amsterdam 2024
Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.

It Doesn't Do What You Think It Does
- 1. IT DOESN'T DO WHAT YOU THINK IT DOES A Survey of Strategies for Gaining Confidence in Applications and Systems Justin Stoller @juststoller justin.stoller@gmail.com
- 2. YOUR TITLE NEEDS A TL;DR way to go...
- 3. So what do we mean by "Gaining Confidence" and why should you care?
- 4. First that we have a clear idea of what we are trying to gain confidence in? What is the value of our software? What are the acceptance criteria? Inputs Outputs Performance Characteristics Visual Style
- 5. Does it meet the acceptance criteria?
- 6. What are the Rewards? What are the Costs? Where are the Risks?
- 7. A Few of the Topics Out of Scope Organization & Communication Architecture & Design
- 8. The Presentation 1. We will start with Language Paradigms and how they affect our abilities farther up the stack 2. Using Language constructs to perform both static analysis (type systems) and dynamic analysis (error handling) 3. Working our way up the stack to explicit low level tests 4. And farther up to higher level integration tests 5. We will look at combining what we've seen above into a simulation testing and the emergent behaviors that are found with these 6. And finally continuing the analysis from simulation into production via monitoring
- 9. You forgot to say why should care...
- 10. Language Paradigms Imperative vs Declarative Low Level vs High Level
- 11. Procedural Type Systems that Model the Components of a Computer Tests assert the state of the world Error Handling by way of return codes Goto like statements
- 12. Object Oriented Type Systems that Model the Application Domain Tests assert the state of an object Tests assert the passing of messages More reliance on type systems Limit exceptional behaviors to the boundaries of the system
- 13. Functional Type Systems that Model the Application Domain Tests assert the state of a returned data structure Tests assert the distribution returned data structures More reliance on type systems
- 14. Logical/Relational Type Systems as Theorem Provers Tests assert the end state of the application
- 15. Testing Layers
- 16. A single unit test of logic: conditional, etc Simple units of logic require simple tests However low level tests tend to be very tied to implementations Good design facility but rarely good at ensuring quality Often written in the language of the software and contains the pros and cons of the software's language
- 17. The behaviors of Integrated Units Tests are tied to behaviors of the systems Increasing complexity of tests and prerequisites Requires decent design, good at gaining confidence
- 18. The System as a Whole What properties does it display Analysis of emergent behaviors
- 19. A wide ranging spectrum Higher level languages start farther up the level of strategies The performance characteristics of the tests determine how often they are ran Higher level tests with simple ways to instantiate them provide more value as ways to gain confidence in the software.
- 20. Novelty in combining concepts Instrumented or "monitored" development environments
