A Top Notch RBCS Employee Soars to New Heights!
Jared Pauletti, RBCS Systems Engineer and Smithson
Valley High School Class of 2017 Valedictorian, is off to A&M
It is with immense pride that RBCS bids farewell to our Systems
Engineer, Jared Pauletti, this month as he heads off to Texas
Jared, Smithson Valley High School class of 2017's
Valedictorian has been an asset to the RBCS team and is a key player
in making sure things operate behind the scenes as they should. He
balances a busy school (and marching band!) schedule with meeting
work deadlines. It goes without saying that he is an intelligent
young man but, on top of it all, he is creative, has an excellent
work ethic, is kind and generous and a good friend.
RBCS team is disappointed to see him leave, but wishes Jared success
and happiness in this next chapter of his life. There is no
doubt he will go far.
Test-Driven Development, Acceptance Test-Driven
Development, and Behaviour-Driven Development
This is an excerpt from Agile Testing Foundations: An ISTQB Foundation Level Agile
Tester Guide, by Rex Black, Marie Walsh, Gerry Coleman, Bertrand
Cornanguer, Istvan Forgacs, Kari Kakkonen, and Jan Sabak, published
July 2017. Kari Kakkonen wrote this selection. The authors are all
members of the ISTQB Working Group that wrote the ISTQB Agile Tester
traditional way of developing code is to write the code first, and
then test it. Some of the major challenges of this approach are that
testing is generally conducted late in the process and it is
difficult to achieve adequate test coverage. Test-first practices can
help solve these challenges. In this environment, tests are designed
first, in a collaboration between business stakeholders, testers, and
developers. Their knowledge of what will be tested helps
developers write code that fulfils the tests. A test-first approach
allows the team to focus on and clarify the expressed needs through a
discussion of how to test the resulting code. Developers can use
these tests to guide their development. Developers, testers,
and business stakeholders can use these tests to verify the code once
it is developed.
number of test-first practices have been created for Agile projects,
as mentioned in section 2.1 of this book. They tend to be called X
Driven Development, where X stands for the driving force for the
development. In Test Driven Development (TDD), the driving force is
testing. In Acceptance Test-Driven Development (ATDD), it is the
acceptance tests that will verify the implemented user story. In
Behaviour-Driven Development (BDD), it is the behaviour of the
software that the user will experience. Common to all these
approaches is that the tests are written before the code is
developed, i.e., they are test-first approaches. The approaches are
usually better known by their acronyms. This subsection describes
these test-first approaches and information on how to apply them is
contained in section 3.3.
Development was the first of these approaches to appear. It was
introduced as one of the practices within Extreme Programming (XP)
back in 1990s. It has been practiced for two decades and has
been adopted by many software developers, in Agile and traditional
projects. However, it is also a good example of an Agile practice
that is not used in all projects. One limitation with TDD is that if
the developer misunderstands what the software is to do, the unit
tests will also include the same misunderstandings, giving passing
results even though the software is not working properly. There is
some controversy over whether TDD delivers the benefits it promises.
Some, such as Jim Coplien, even suggest that unit testing is mostly
is mostly for unit testing by developers. Agile teams soon came
up with the question: What if we could have a way to get the benefits
of test-first development for acceptance tests and higher level
testing in general? And thus Acceptance Test-Driven Development was
born. (There are also other names for similar higher-level
test-first methods; for example, Specification by Example (SBE) from
Gojko Adzic.). Later, Dan North wanted to emphasize the
behaviours from a business perspective, leading him to give his
technique the name Behaviour-Driven Development. ATDD and BDD
are in practice very similar concepts.
look at these three test-first techniques, TDD, ATDD, and BDD, more
closely in the following subsections.
concept is not unique or new to Agile development. Boris Beizer, in
his book Software Testing Techniques, talks about the value of
a test-first approach to software development.
can find the initial description in Kent Beck's Test-driven Development: By
widely-read source on the topic is Adzic's Bridging the
communication gap: Specification by Example and Agile Acceptance
good discussion on this topic is Chelimsky's The RSpec Book:
Behavior Driven Development with Rspec, Cucumber, and Friends.
