The document discusses different types of software tests including unit tests, integration tests, acceptance tests, load tests, and performance tests. It emphasizes the importance of unit tests for validating individual code modules and classes work as intended. Writing unit tests before coding allows developers to test complex scenarios quickly, ensure code quality and readability, and refactor code with confidence.
This presentation has been prepared to share knowledge about JetBrains UpSource tool usage on HTML project for back-end developers. Also code review process description has been provided to share good/bad experience of code review procedure.
We investigate one of the most popular approaches to creating software: test driven development. From the basic understanding why tests are important to a new software development paradigm, where you start with tests and them do the implementation. We glance over different areas of testing and see how one should really do the software testing in different situation.
In this experiential webinar, our guest Mohamed Shaaban will share with you his wide experience in Unit Testing in addition to practical techniques for unit testing your code using C#, NUnit, and Moq.

Testers entering the Agile domain are no longer on the other side of the wall. Without the wall, the developer playground of CI is a testing smorgasbord. As an Agile Tester there are many ways to consider how to design and execute automated tests and continuously keep the pulse on quality of the builds. However when it comes to leveraging existing CI pipeline for functional and performance tests many testers may not realize that main ingredients are already built-in. This presentation will share the recipes on how to propel functional and performance automated tests with immediate test results feedback to the entire team with your existent CI engine.
Presentation is base on:
• Hudson/Jenkins CI engine
• Ruby and Rake to setup, execute and tear-down test environments
• Hpricot (Ruby gem) and Hudson plug-ins to report and trend graphical results dynamically
From http://wiki.directi.com/x/AgAa - This is a 24 slide internal presentation covering virtues of Automated Testing vs Manual Testing. Inkeeping with our agile adoption this presentation covers various advantages (11 to be specific) obtained in using TDD and Automated Testing as opposed to Manual Testing
Code Review tool for personal effectiveness and waste analysisMikalai Alimenkou
Usually it is hard to analyze personal effectiveness and detect wastes in development process because developer’s work decomposition is not transparent and available for analysis. As a good sample of ineffective process imagine developer, who spends 1 day on task implementation and then reimplements it several times according to code review notes during next 2 days. Or another developer, who is waiting for code review during 2 days, switching context to other tasks, finally gets notes and switches back to initial task, trying to refresh all details in his head. And so on and so forth…
Code review tool usage helps to aggregate lots of useful information about any code change at any stage (static analysis, code review, rework, acceptance, integration into main branch). In this talk I’m going to demontrate how this information could be used for detailed analysis of development effectiveness and wastes detection. Based on mentioned analysis you could implement many improvements for your development process and then measure their success.

Play with Testing on Android - Gilang Ramadhan (Academy Content Writer at Dic...DicodingEvent
Testing merupakan (QA) quality assurance dari sebuah produk. Dalam tahap ini kita jadi tahu, bila di dalam aplikasi yang kita buat terdapat bug, eror, atau salah dalam logika kode. Sehingga testing adalah bagian terpenting pada pengembangan aplikasi.
Eror bisa kita identifikasi jauh lebih dini sebelum proses produksi. Jika terjadi kesalahan dalam tahap produksi, itu sudah melibatkan user. Tentunya kerugian di dalam tahap ini akan lebih fatal. Faktanya, biaya perbaikan sebuah aplikasi eror di tahap produksi, lebih besar dibandingkan dengan biaya pengujian sebelum produksi.
Anda akan mempelajari:
- Mengapa perlu melakukan testing
- Apa sebenarnya yang dimaksud testing
- Apa saja tools yang bisa Anda manfaatkan

[AnDevCon 2016] Mutation Testing for AndroidHazem Saleh
Unit testing coverage is a great way to show us the amount of tested lines and branches of code, but is this really enough? The answer is "no" since unit testing coverage does not really fully measure the efficiency of the unit tests.
This is why there is a need for having techniques that show unit tests efficiency. Mutation testing is one of these powerful techniques. The main idea of mutation testing is to perform byte code modifications (mutations) to original Android app source code and then run app unit tests to check if they are strong enough to fail as a result of these mutations.
This session discusses mutation testing techniques, and demonstrates PIT as a powerful mutation testing tool for Android apps with demos.
Test-Driven Developments are Inefficient; Behavior-Driven Developments are a ...Abdelkrim Boujraf
In summary, we have presented here a method for efficiently testing large parts of web-based software by using elements of code generation to generate automatable tests, and by using BDD concepts to model tests for non-generated screens and non-generated business actions. Further, we have described a method for context-based unit
testing that, when combined with generated code and tests, yields an acceptable trade-off between development efficiency and time spent on testing

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.

4. TYPES OF TESTS
Test Type To Confirm That:
Unit Tests
Low level functions and classes work as expected under
a variety of inputs.
Integration Tests
Integrated modules work together and in conjunction with
infrastructure such as message queues and databases.
Acceptance Tests
Your application and key user flows works as a complete
black box when driven via the user interface.
Load Tests
Your application performs well under simulated real world
user load.
Performance Tests
The application meets performance requirements and
response times under real world load scenarios.
Simulation Tests
Your application works in device simulation
environments. (This is growing in importance in the
mobile world where you need to test software on diverse
emulated mobile devices.)
Smoke Tests
Tests to validate the state and integrity of a freshly
deployed environment.
Quality Tests
Application code is high quality – identified through
techniques such as static analysis, conformance to style
guides, code coverage etc.
8. >> Unit tests are written by
programmers to ensure that the
code does what they intend it
to do.
Uncle Bob (Robert Martin)
>> It is difficult to claim that you are Agile, if you are not
writing lots of automated test cases, and writing them
before you write the code that makes them pass.
https://sites.google.com/site/unclebobconsultingllc/tdd-with-acceptance-tests-and-unit-tests
But there are two different kinds of automated tests recommended by the Agile disciplines.
Unit tests, which are written by programmers, for programmers, in a programming language. And acceptance tests, which are written by business people (and QA), for business people, in a high level specification language (like FitNesse www.fitnesse.org).
Complex code with few dependencies (top left). Typically this means self-contained algorithms for business rules or for things like sorting or parsing data. This cost-benefit argument goes strongly in favour of unit testing this code, because it’s cheap to do and highly beneficial.
Trivial code with many dependencies (bottom right). I’ve labelled this quadrant “coordinators”, because these code units tend to glue together and orchestrate interactions between other code units. This cost-benefit argument is in favour of not unit testing this code: it’s expensive to do and yields little practical benefit. Your time is finite; spend it more effectively elsewhere.
Complex code with many dependencies (top right). This code is very expensive to write with unit tests, but too risky to write without. Usually you can sidestep this dilemma by decomposing the code into two parts: the complex logic (algorithm) and the bit that interacts with many dependencies (coordinator).
Trival code with few dependencies (bottom left). We needn’t worry about this code. In cost-benefit terms, it doesn’t matter whether you unit test it or not.
http://blog.typemock.com/2011/11/28/10-reasons-to-write-unit-tests
Test complex scenarios quickly, without having to manually reproduce them in the application.
By testing often, you don’t break the application as you go. You can’t always know the indirect implications of what you’re writing, especially if you didn’t write the original application.
You ensure readability. A unit test makes the purpose of your code easier to understand.
You ensure maintainability. Unit-testing forces you to better encapsulate functionality, thus making it easier to maintain and add new features.
Refactor without worries. Run the tests to make sure everything still functions as intended.
Save time on testing. You can test the entire application at the speed of your CPU.
Feel safer. How many times were you afraid to add a new feature or change something in your application’s core? No more!
Bonus: know exactly what is broken. Instead of hunting for an obscure bug, let the tests tell you what’s wrong and why. Example: the application will tell you when you add an item to a cart but the cart still appears empty. It will also tell you what item you tried to add for the cart to break.

By having to Craft unit tests, developers are forced to think as consumers of their code. This gives them an extra motivation to build an application programming interface (API) that is clear, and easy to implement.
