Resumo(s)
One of the main reasons software projects fail is the lack of communication between
stakeholders. Low Code Platforms have been recently growing in the software development
market. These allow creating state-of-the-art applications with facilitated design
and integration, in a rapid development fashion and as such, avoiding communication
errors among stakeholders is indispensable to avoid regressions. Behavior-Driven Development
(BDD) is a practice that focuses on developing value-based software, promoting
communication by bringing business people into development.
The BDDFramework is an open-source testing automation framework within the Out-
Systems environment. It allows describing test scenarios using the Gherkin syntax but it
is not focused on enabling the BDD process. Our main challenge is: - How can we apply
the BDD process in Low Code and support it from a technological point of view, considering the
particularities of Low Code environments and having as case study the OutSystems platform?
Is the BDDFramework prepared for this?
We interviewed some people in the domain to understand their development and testing
challenges and their experience with the BDDFramework. With the information gathered
and after studying other existing BDD process supporting tools for other languages,
we built a prototype that uses the existing BDDFramework and automates it, allowing
scenarios to be described in text files, which helps the introduction of business people in
the process. The prototype generates all the test structure automatically, reusing equal
steps while detecting parameters in the Gherkin descriptions.
We performed some real user testing to validate our prototype and we found that our
solution was faster, easier, with better usability and we obtained more correct tests than
with the previous approach - the BDDFramework alone.
Testing in Low Code is still an area with a lot to explore and errors have a huge impact
when development is very accelerated, so as communication errors tend to decrease we
can start building software even faster and this is what BDD proposes to solve. With this
prototype we have been able to demonstrate that it is possible to build a framework that
will allow us to enable this process by taking advantage of the OutSystems language particularities
to potentiate the BDD practice technologically, while setting a test standard
for the OutSystems language.
