Unit testing
Unit testing involves testing individual units or components of an application to verify that each unit performs as expected. A unit test automates the invocation of a unit of work and checks the expected outcome without relying on other units. Good unit tests are automated, repeatable, easy to implement, run quickly and consistently, and isolate the unit from its dependencies. Integration testing differs in that it involves testing units using real dependencies rather than isolated fakes or stubs. Test-driven development involves writing tests before code so that tests fail initially and then pass after the code is implemented. Unit testing frameworks like NUnit provide attributes to mark tests, expected exceptions, setup and teardown methods, and assertions to validate outcomes.
An Introduction to Unit Test Using NUnit

RandomTest - Random Software Integration Tests That Just Work for C/C++, Java...
This document describes RandomTest.net, a tool for generating random integration tests. It discusses some limitations of traditional unit and manual testing approaches. RandomTest.net aims to minimize QA effort through test automation using random inputs and assertions to verify results. Developers embed assertions in code and RandomTest.net randomly executes code sections to detect failures. Any failed assertions are collected in a central repository. The tool currently supports C/C++, Java and PHP with more languages to come. It is open source and additional documentation can be found at randomtest.net.
Black box testing
Dynamic black-box testing involves testing software without knowledge of its internal code by entering inputs, observing outputs, and checking results. The document discusses techniques for effective dynamic black-box testing including reducing test cases using equivalence partitioning, identifying boundary conditions, using various data values and states to find bugs, and applying repetition and high loads. It also covers using exploratory testing when requirements are not available and the approaches of test-to-pass and test-to-fail.
Equivalence class testing
Equivalence class testing is a software testing technique that divides input values into valid and invalid categories called equivalence classes. Representative values are selected from each class as test data. This technique reduces the number of test cases needed while maintaining thorough coverage. An example divides numbers into classes of valid 2-3 digit numbers and invalid single digit numbers to test a program's valid and invalid number handling. There are different types of equivalence class testing that vary in robustness. The technique helps reduce testing time and cases but requires expertise to define classes and may not test all boundary conditions.
Software Testing Foundations Part 4 - Black Box Testing
The document discusses various black box testing techniques including:
- Equivalence class partitioning which involves testing representative values from valid and invalid equivalence classes
- Boundary value analysis which checks values at the boundaries of equivalence classes
- State transition testing which designs tests based on a system's state diagram
- Cause-effect graphing and decision tables which identify test cases based on input-output dependencies
- Use case testing which designs tests based on typical user interactions described in use case diagrams
The document provides examples and best practices for applying each technique. Black box testing verifies functionality but cannot detect faults in specifications or undocumented requirements.
H testing and debugging
The document discusses testing and debugging software. It describes the purpose of testing as ensuring software is fit for purpose by meeting specifications and is robust and reliable. Various types of tests are described, including normal, extreme, and exceptional test data and inputs. The importance of systematic and comprehensive testing is emphasized.

Limitations are that tests only check for certain errors and require additional test code. Common unit testing tools include JUnit and Mock objects which simulate objects for testing. Integration testing combines modules tested individually. Continuous integration runs automated tests and builds on every code change. Continuous delivery fully automates the software delivery process.
Software Testing
Software testing is the process of verifying that software programs perform as intended. It involves executing a program to identify bugs. The V-Model is a software development lifecycle model where each development stage is paired with a corresponding testing stage. Unit testing verifies individual program modules, integration testing checks module interactions, system testing evaluates full functionality, and acceptance testing evaluates the program in its actual environment. Techniques like equivalence partitioning, boundary value analysis, and finite state machine diagrams help guide effective testing. Integration testing in particular helps find interface and data flow issues early in development.
Unit testing, principles
Unit testing tests individual units of source code to determine if they are fit for use. It is different from integration testing, which combines modules, and validation testing, which checks that a system meets specifications. The goal of unit testing is to isolate and test each part of a program to show that individual parts are correct. Unit testing provides benefits such as finding problems early, facilitating automated testing and change, and improving software quality. Guidelines for effective unit testing include knowing the objective of each test, making tests self-sufficient, ensuring tests are deterministic, following naming conventions, duplicating code for readability, testing results not implementation, and using isolation frameworks.

Join me in this session as we dive into each AWS hosting service to determine which one is best for your scenario and explain why!
Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

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.
"Choosing proper type of scaling", Olena Syrota
Imagine an IoT processing system that is already quite mature and production-ready and for which client coverage is growing and scaling and performance aspects are life and death questions. The system has Redis, MongoDB, and stream processing based on ksqldb. In this talk, firstly, we will analyze scaling approaches and then select the proper ones for our system.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
A Deep Dive into ScyllaDB's Architecture
This talk will cover ScyllaDB Architecture from the cluster-level view and zoom in on data distribution and internal node architecture. In the process, we will learn the secret sauce used to get ScyllaDB's high availability and superior performance. We will also touch on the upcoming changes to ScyllaDB architecture, moving to strongly consistent metadata and tablets.

"$10 thousand per minute of downtime: architecture, queues, streaming and fin...
Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.
Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

- 2. What is a unit test ? A unit test is a piece of code that invokes a unit of work and checks one specific end result of that unit of work. If the assumptions on the end result turn out to be wrong, the unit test has failed. A unit test’s scope can span as little as a method or as much as multiple classes.
- 3. How you test right now ? AuthService .login { … }
- 4. What are problems in previous case?
- 5. • It’s considered an integration test • It’s redundant for many test cases • Must test every cases after modifying the code in the same unit • Other team members don’t know how to test it
- 6. What makes a good unit test • It should be automated and repeatable • It should be easy to implement • It should be relevant tomorrow • Anyone should be able to run it at the push of a button • It should be run quickly • It should be consistent in its results (it always returns the same result if you don’t change anything between runs) • It should have full control of the unit under test • It should be fully isolated (runs independently of other tests) • When it fails, it should be easy to detect what was expected and determine how to pinpoint the problem Art of unit testing 2nd(1.2 Properties of a good unit test).
