Test-Driven Development (TDD) is a software development process that relies on writing automated tests before developing code to pass those tests ("red-green-refactor"). TDD promotes writing isolated, repeatable unit tests and decoupling code from external dependencies through techniques like dependency injection and mocking. While TDD has benefits like ensuring quality and preventing regressions, it has also received criticism for potentially leading to over-testing and an over-reliance on mocking. The presentation concludes with an open discussion of experiences and opinions on TDD.
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.

AATs can be expensive and not valuable if not done right, and doing them right is not easy. They provide enormous benefit though, and are critical as software takes over the world and manual regression testing becomes infeasible. This goes through key benefits.
Why Automated Testing Matters To DevOpsdpaulmerrill
“Automated testing is a pain in my ear! Why can’t QA get it right? Why do the tests keep breaking? And for Pete’s sake, stop blaming the infrastructure!”
…Ok, maybe you chose a different word than “ear”.
How often do you have thoughts like this? Daily?
Let’s talk about these frustrations, why they exist and how we can use them to improve our systems!
In this talk, Paul Merrill, founder and Principal Automation Engineer at Beaufort Fairmont explores why automated testing matters to DevOps. Join us to learn how automated testing can be a useful tool in the creation and release of your systems!

We are entering a world where everything must be done quicker. You must deliver code faster. You must deploy faster. How can you deliver and deploy faster without compromising your professionalism? How can you be sure you are delivering what your client has asked you?
In short, testing is the only way to be sure you’re delivering what someone asked you to. Often we use BDD Tools such as FitNesse which gained popularity over the recent years
There are a number of integration / BDD test tools out there that help you deliver a high quality software through tests. Its easy to pick up any tool from just their tutorials and start writing tests. But as I found out the hard way, this can quickly spiral into a state where the tests are giving you and your team hell and are worth less than the value the tests are delivering.
Using FitNesse and Junit as examples, I will share things that I have learnt working on large enterprise and vendor systems and help you avoid your own path to hell.
Learn about the benefits of writing unit tests. You will spend less time fixing bugs and you will get a better design for your software. Some of the questions answered are:
Why should I, as a developer, write tests?
How can I improve the software design by writing tests?
How can I save time, by spending time writing tests?
When should I write unit tests and when should I write system tests?
One of the cornerstones in Agile development is fast feedback. For engineering, "fast" means "instantly" or "in 5 minutes", not "tomorrow" or "this week". Your engineering practices should ensure that you can answer yes to most of the following questions:
- Do we get all test results in less than 5 minutes after a commit?
- Is our code coverage more than 75% for both front-end and back-end?
- Can we start exploratory testing in less than 15 minutes after a commit?
- Do all our tests pass more than 90% of our commits?
This talk will give you practical advice on how to get to "yes, we get fast feedback".

This webinar covers the role of TDD and CI and what pitfalls to watch out for.
Stay tuned for Synerzip's upcoming webinars that you might be interested in https://www.synerzip.com/webinars/
Despite the belief that a shared context and collaboration drives quality, too often, software testers and quality professionals struggle to find their place within today's integrated agile teams. This session is a practitioner’s view of testing and testing practices within an iterative/incremental development environment. We will begin with a discussion of some of the challenges of testing within an agile environment and delve into the guiding principles of Agile Testing and key enabling practices. Agile Testing necessitates a change in mindset, and it is as much, if not more, about behavior, as it is about skills and tooling, all of which will be explored.

Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

1. Test-Driven Development
Code testing, mocking, dependency injection, benefits and recent criticism
Mayank Srivastava
Manager and Evangelist
www.MayankSrivastava.com
http://www.mpspartners.com/blogs
@MayankSri
2. Know your audience
• Didn’t quite use TDD but used Unit / integration tests.
• Used TDD on a project.
3. What we will cover today:
• TDD concept
• Unit test
• Dependency Injection
• Resource Mocking
• Integration tests
• Best Practices
• Recent Criticism
• Open forum (Opinions, comments, experiences, questions)
5. Agile
• Iterative & incremental
• Small manageable units of work
• Collaboration between self-organizing, cross-functional teams
• Develop small pieces and put it before the user first.
• Adaptive, evolutionary development & delivery
• Built to last – rapid and flexible response to change
6.
7. Test-driven development relies on the repetition of a very
short development cycle:
First the developer writes an automated test case that defines a
desired improvement or new function,
then produces the minimum amount of code to pass that test,
And finally refactors the new code to acceptable standards.
10. You need TDD
If you
• Are going to maintain code base developed by other developers.
• Work with developers who do not accept their code has bugs.
• Are going to make changes to someone else’s code and then
someone else is not available before deployment.
• Spend good amount of time trying to identify what par of the code
base is causing the problem.
11. TDD - key benefits
• Test is written against requirements.
• Provides built-in regression testing.
• Testable code, by design, follows SOLID principals.
• Ensure quality from the start.
• Puts an end to recurring bugs from Waterfall.
12. Unit Test
A test written to validate “One (logical) Unit” of work.
Unit
• Isolated from other code
• Isolated from other developers
Test
• Targetable
• Repeatable
• Predictable
13. Decoupling the Unit with Dependencies
You unit of work is dependent on external resources like:
• A persistence medium
• Logging system
• A caching mechanism
• An external service like a web or windows based service.
25. Integration test
• Any test that crosses the boundary of a Unit is Integration test.
• A full spike - end to end feature test.
26. Best practice / lesson learnt
• Naming test cases (Readable & Verbose)
• Exhaustive test cases – pass, fail, corner cases and conditions
• Test only the code you wrote.
• Must target all business logic / features.
• Limit mocking maintenance burden.
• Don’t cheat… ever (once or twice is enough to bring the suite down)
27. Recent criticism - TDD is dead. Long live Testing.
• Unit testing is very shallow and it does not has a cross layer reach.
• Too much focus on execution time of the regression test suite.
• TDD tends to Mocks heavy architecture, everything stubbed out creates refactoring difficult.
• Red-green-refactor loop – less optional and more of a mandate. Some developers do not really enjoy that
development.
• TDD nudges towards over testing cost, testing code is still code that needs maintenance.
• Reduced QA people – the person who created cannot be the person who will test to break. But in reality, it
eliminated the testers who only run pre written test scripts.
• Cost Vs life of the system (ignore rare cases)
6 Google hangout sessions on YouTube - http://www.youtube.com/watch?v=z9quxZsLcfo
28. Benefits
• Business requirement are living running test cases not document that
can be missed.
• Have I broken anything while making a change? – Self testing
regression suite.
• Is this code base healthy? The code base is handed over to different
