Unit testing involves testing individual software units or components in isolation from the rest of the system to determine if they are fit for use. It aims to validate that each unit of code performs as expected and detects errors. Unit tests should be independent of each other and test a single unit or function. They are written by developers during development to validate code meets requirements and protects against regressions when code is modified.
Lets break some code. In this workshop we will be going over some of the fundamental concepts of software testing and take a hands on approach to writing Unit and Integration tests. We will cover topics such as mocking, stubbing, database patching and how this can all fit into a continuous integration environment like Jenkins.
A short presentation slide deck I gave to interns we have this summer of 2019 on (unit) testing in software development. This is not a code-centric slide deck and just looking at the slides loses some context without being there in person, or having discussions, etc.

Software Testing has become a necessity for today's IT industry. Every IT engineer is expected to understand the basic of software testing and it types. This PPT will enable the viewers to understand the concept of software testing and types of testing.
Software testing is a process of executing a program or application with the intent of finding the software bugs. It can also be stated as the process of validating and verifying that a software program or application or product: Meets the business and technical requirements that guided it's design and development.
An error is a mistake, misconception, or misunderstanding on the part of software developer.
A fault or defect is introduced into the software as the result of an error. It is an anomaly in the software that may cause it to behave incorrectly, and not according to its specification.
A failure is the inability of a software system, or component to perform its required functions within specified performance requirements.
A test case in a practical sense is a test-related item which contains the following information:
A set of test inputs: These are data items received from an external source by the code under test. The external source can be hardware, software, or human.
Execution conditions: These are conditions required for running the test, for example a certain state of a database, or a configuration of hardware device.
Expected output: These are specified results to be produced by the code under test.
Test – A test is group of test cases, or a group of related test cases and test procedures.
Test Oracle – It is a document, or a piece of software that allows testers to determine whether a test has been passed or failed.
Test Bed – A test bed is an environment that contains all the hardware and software needed to test a software component or a software system.
This presentation will give you a fuller understanding of unit testing in Swift, its benefits, key characteristics, mocks and stubs, dependency injection, DI patters and common mistakes one may make throughout the process.

Spock testing gives you the option of testing your grails application with accurate results.
The tutorial includes a Testing overview, understanding how unit Testing works, brief about Spock Unit Testing, Writing Unit test cases, Demo & exercise. The tutorial begins with a section which gives an overview on Testing. It includes the reason to test a program, a way of thinking about testing and also includes integral development through testing like unit testing, integration testing, functional testing, acceptance testing. The overview section is followed by the Understanding section. It includes understanding unit testing, disadvantages of unit testing like test cases, advantages of unit testing like facilitating changes, simplifying integration, evolving design etc.
Afterward comes a section about Spock Testing. It includes a brief about Spock Testing, basics about Spock Testing, specifications of Spock Testing. The next section is a brief about Unit test cases. It includes Writing Unit test cases like fields like declarations, fixture methods for setting up the environment, blocks like setup, expect, where, expert block and an example.
The last section of this tutorial is about the exercises on Testing. This section can also be called Data driven Testing and includes data tabes which are a feature method, data pipes which connect a data variable to a data provider, @unroll which has its iterations reported independently, exception conditions which tell us about when a block should throw an exception, mocking which is used for implementing objects, test mixins which enhance the behavior of a typical JUNIT, test for annotations which is a class under test, mock annotations which create a mock version of any collaborators, cardinality describes how often a method call is expected and at last stubbing which is an act to respond to the method calls.
Unit Testing in Android is done with JUnit. There are lots of topic to cover such as Test Double, Test Driven Development, Black Box and White Box Testing.
I hope this slide will be helpful to you to know Unit Testing in short times.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
