MO Essential Test-Driven Development
Rob Myers, Agile Institute
Mon, 06/02/2014 - 1:00pm

Test-driven development (TDD) is a powerful technique for combining software design, unit testing, and coding in a continuous process to increase reliability and produce better code design. Using the TDD approach, developers write programs in very short development cycles. The developer first writes a failing automated test case that defines a new function or improvement, then produces code to pass that test, and finally refactors the new code to acceptable standards. The developer repeats this process many times until the behavior is complete and fully tested.

TF Software Design for Testability
Keith Stobie,
Tue, 06/03/2014 - 8:30am

Testability is the degree to which a system can be effectively and efficiently tested. This key software attribute indicates whether testing (and subsequent maintenance) will be easy and cheap—or difficult and expensive. In the worst case, a lack of testability means that some components of the system cannot be tested at all.

Agile has not only gone mainstream, it’s gone global. Data on agile team performance, time-to-market, and quality have emerged in the past decade. In 2012, a group of Columbus, Ohio, companies—business, IT, and financial services firms—participated in the first ever “Columbus Agile vs. the World” study. They collected velocity, schedule, effort, staffing, and quality data which were compared against QSM’s Software Lifecycle Management (SLIM) database. Analysis revealed delivery was 31 percent faster with 75 percent fewer defects than industry norms. Enter Munich, Germany.

K4 Producing Product Developers
David Hussman, DevJam
Thu, 06/05/2014 - 3:45pm

Many teams and organizations have found agile methods help them produce more. Where critical thinking is alive, a more important question arises: Are we producing the right thing? Even though agile tools and processes have helped produce more, they often fail to help us produce the right product, change our focus to product over process, or improve product learning.

Concurrent Sessions

AW2 Story Maps, Customer Journeys, and Other Product Design Tools
David Hussman, DevJam

Are you sure you are building the right product? Although agile methods help teams build products faster, many teams struggle to validate customer direction or product features. Some teams talk about “grooming the backlog” but still find their stories are not strong. If you’re struggling with bad backlogs or weak stories, this session is for you.

AT10 Test-Driven Development Illustrated

Agile methods help development teams create good quality code and ensure this with early testing. Test-driven development (TDD) is the preferred approach to accomplish this. First, you write the tests; then, you write the code so the tests pass. Sound simple? It is—when done correctly. And this is often where the trouble starts. Thorsten Werle and Carsten Czeczine explain the basic steps of TDD. You’ll see how to write tests for non-existing code using the compiler as your first testing tool. You’ll learn that TDD does not start with unit testing but with an integration test.
