Better Software West 2018, Agile Dev West 2018, DevOps West 2018 The Impact of Agile Quantified
Slideshow

For years, people have made recommendations for how to develop software in an agile way based almost entirely on intuition, folklore, and anecdotes. They've never been able to quantitatively show the accuracy or applicability of these recommendations. This session quantifies those recommendations in the most precise and objective terms, including a presentation of general findings in Larry Maccherone's research correlating agile practices to performance along the dimensions of productivity, predictability, quality, and time to market. These data can be used to make general decisions about what to focus on. The presentation also includes the numbers, so that instead of just saying that A is better than B, we can say that A is a 24 percent improvement in quality but a 10 percent reduction in productivity compared to B.

Better Software West 2018, Agile Dev West 2018, DevOps West 2018 Overcoming Test-Driven Damage
Slideshow

Test-driven development is supposed to help us refactor our code safely, but we often find that when we refactor our code, we also have to refactor our tests. What was supposed to add safety becomes a burden requiring time and effort. Writing good unit tests is a critical skill that developers need to master in order to get the most benefit from test-driven development. Tests must be unique, written at the right level of abstraction, and implementation-independent in order to be most valuable. In this session, David Bernstein will cover effective techniques for doing TDD that support building useful tests and quality code. You’ll learn how to approach TDD in a way that yields the right number and kind of tests to support improved refactoring. Working through a few code examples, you’ll see how many assertions are required to specify a linear range, exceptions, and other boundary conditions.

STAREAST 2018 DevOps Tools for Winning Agility
Slideshow

With a myriad of tools to choose from—open source, free, paid, and enterprise level—teams and organizations have seemingly endless options. Making the right tool decisions can impact the level of quality and success within DevOps projects. Kellyn Pot'Vin-Gorman discusses different tools, what tools work best together, and how—even in teams that are in silos—the right choices can make the difference between success and failure in DevOps implementations. Explore tools—such as Ansible, Jenkins, Maven, Delphix, Github, Liquibase, and Terraform—for automating builds and virtualization. Review reasons for choosing open source, “freemium,” or enterprise tools along with different hybrid tool combinations and explore why companies face new challenges as DevOps tools mature.

STAREAST 2018 API Testing: How to Write Tests, Integrate into CI, and Track What You're Testing
Slideshow

Some developers and testers think that APIs, whether internally developed or not, should just work. Unfortunately, without a significant amount of focus on testing API services, one little flaw can spell disaster for your application—especially security vulnerabilities where hackers will target your application. Elise Carmichael discusses the risks of not fully testing APIs, how to be sure that all services are tested fully, and the types of negative testing you need to do on APIs. She shows you a method to organize your tests using Postman, a tool for REST web services testing. During this session, Elise and the participants will write some Postman API tests with variables and then execute the tests with Newman, a command line application for running Postman tests that you can include in continuous integration scripts.

We Are Doing Agile But, But, But …
Slideshow

“We are doing agile, but the only tests we do in a sprint are unit tests” or “We are doing agile, but we have a hardening phase at the end, which is really more of a system integration test” or “We are doing agile, but testing is done by a separate test team.” Sound familiar? Gitte Ottosen...

BSE Testing Eliminate Cloud Waste with a Holistic DevOps Strategy
Slideshow

Chris Parlette maintains that renting infrastructure on demand is the most disruptive trend in IT in decades. In 2016, enterprises spent $23B on public cloud IaaS services. By 2020, that figure is expected to reach $65B. The public cloud is now used like a utility, and like any utility...

BSE Testing Measure Anything: The Quality, Productivity, Predictability, and Engagement Model
Slideshow

Measuring software development is difficult. Measuring the return on investment (ROI) of complex initiatives (such as adopting agile) is even more difficult. One department at IBM struggled to reduce a list of 150 metrics down to a top twenty to use in consulting engagements. Through the...
