BDD can help save Agile by facilitating three main outcomes: shared understanding, business readable specifications, and living documentation. BDD involves discovering business needs through workshops, formulating examples and scenarios in a business-readable way, and automating tests to create living documentation that ensures everything continues to work as intended. Practicing BDD improves collaboration, delivers working software based on business needs, and guides development with up-to-date documentation.

Notas del editor
- Laurent will start. Views about success and failures of agile
- Now you might well be sitting there thinking: “that’s a pretty… confident talk title” AINO Modern agile; XP; SAFe etc.
- Let’s stick with the most common agile “methodology” Laurent will tell a story about Zephyr over the next 3 slides.
- This is what Scrum promises …
- But this is what you need to succeed
- Seb takes over.
- Same as ATDD & Spec By Example
- Not a process, not a methodology, definitely NOT A TOOL
- - a collection of tried and tested techniques that support individuals and interactions
- 3Iterative. One story at a time. Try to start with Discovery and work your way down. You will get value from Discovery on its own. Teams often run into problems if they pursue automation on its own. Seb will tell a story about a bank that thought that BDD was synonymous with automated end-to-end testing.
- This is what each practice delivers
- Seb continues
- We often *think* we understand what we’ve been told, but we always have to check
- Slow feedback. Context switching. Rework! By banishing misunderstandings, concrete examples help us deliver more reliably
- 3 Amigos. Example mapping. Note SMALLER STORIES
- Seb tells his “version” story from an insurance company.
- Seb to lead
- Laurent will have story to share – Seb will ask him to tell it.
- DDD Ubiquitous language Example of a commonly misunderstood term? e.g. Exception or Customer or Account
- Story … the team where the scenarios were only written & read by testers (or BAs or PO)
- Laurent will take over here… You don’t NEED to do this to succeed at BDD!
- Technical discipline: let the failing specification guide the development team more automation != good automation fast feedback, so banish slow test runs have confidence in your software (BDD & TDD)
- Publish your living documentation where everyone can read it & see which specifications are passing.
- Publish your living documentation where everyone can read it & see which specifications are passing.
- Listening to tests: If they fail, fix the documentation or the code. If they flicker, don’t ignore them – flickering tests are worse than no tests If the business (PO/BA/Customer) aren’t reading them & giving the team feedback, then they’re not delivering value. Collaborate to ensure the living document is acting as a valuable artefact (for today & tomorrow).
- It takes time to get good at anything. Short cuts inevitably lead to costly rework later – in requirements, specification, or test automation. Collaboration is essential to capture requirements/specs so that they are useful to everybody (both during initial development & future maintenance) Technical discipline is essential to write maintainable code – production & test automation
- Examples of tools used by Smartbear teams when doing BDD.
