Agile development and functional testing: friend or foe? With a hint of HP Quality Center Tom Vercauteren, June 26th, 2009
User stories • Sprint backlog • Daily stand-up • Sprint burn down • Other ideas
User stories In HP Quality Center • We test “per User Story”, and these stories are “bundled” in Sprints:
User stories In HP Quality Center • Sprints contain a number of Stories:
User stories In HP Quality Center • When a Story is being developed, we write tests:
User stories In HP Quality Center • When a Story is developed, we execute tests:
User stories And acceptance criteria • What the customer tells you: “As a customer I want to open a document so that I can view it.” • What comes up along the Sprint: • We only want to view PDF files. • Large files should still be opened within 5 seconds. • I want to open the file in my browser, or save it to my hard disk. • This information is usually “found” in the daily stand-up meeting, and told to the developer. • It is almost never formally captured. • It might be forgotten in the next sprint, or during testing.
User stories And acceptance criteria • According to Scrum, we should add “acceptance criteria”: • After the sprint, add them to the functional documentation! US-25504 Document viewer 2 story points File of 10 MB: < 5 sec. Only PDF Open in IE Save to disk
User stories And acceptance criteria • Who? • Anyone who thinks of them / discovers them. • Why? • Don’t forget them during development or testing. • Might even end up in documentation / user manual. • What? • Any functional or technical “need to know” item. • When? • During daily stand-up • Any time!

Sprint backlog – Sprint planning And functional testing US-25504 Document viewer 2 story points Sprint backlog HP Quality Center
Sprint backlog – Sprint planning And functional testing • Sprint backlog: • Contains Spikes • Contains Technical User Stories (e.g. “setup acceptance environment”, “write manual”, …) • Contains Functional User Stories • HP Quality Center • Does not contain Spikes • Does not contain Technical User Stories • Contains a set of tests for every Functional User Story • Contains non-functional Acceptance Criteria (e.g. “UI should work on 7 different browsers)
Sprint backlog – Test preparation And functional testing US-25504 Document viewer 2 story points Task … 25504 Task 1 25504
Sprint backlog – Test execution And functional testing US-25504 Document viewer 2 story points Test this. 25504 • Use “testable” for shared testers(or “finished” for Spikes) • Use tasks for dedicated testers Note: test work should be subject to “planning poker” (even if you use “testable”) OR Testable
Sprint backlog – Test execution And functional testing • This may include regression tests. US-25565 Importer Validation 2 story points Testable
Sprint backlog – Defect tracking And functional testing
Sprint backlog – Defect tracking And functional testing • Decision make by team: • Fix in this Sprint • Add to Product Backlog, for later fixing • “not a bug” US-25504 Document viewer 2 story points 2609 No error msg. on import of DOC 25504 Testable
Sprint backlog – Re-testing And functional testing US-25504 Document viewer 2 story points Testable • Developer updates HPQC: • Fixed in what release? • What was the problem?
Sprint backlog – When testing is “done” And functional testing • “Q.C. passed” means that no significant problems were found (given the limited time the tester spent on this story) US-25504 Document viewer 2 story points Q.C. Passed 25504
Sprint backlog – When testing is “late” Bugs are found “during the next sprint” • Create a dummy User Story. • As this story will contain bugs that belong to the previous sprint, this has high business value. Bugs previous sprint 2609 No error msg. on import of DOC 25504
User stories • Sprint backlog • Daily stand-up • Sprint burn down • Other ideas
Daily stand-up And the tester • The tester should be present at the daily stand-up meetings. • If you share a tester between projects, he should still be present at least twice a week. • Best practice: “all shared team members (tester, customer rep., project manager, …) attend our daily scrum at least on <weekday>” • Best practice: “As a shared team member, I always inform the team of when I’ll (not) attend the daily scrum.”

Sprint burn down And defects found US-1 testable Defects found US-1 “Q.C. passed” US-2 testable Add 15% story time for bug fixes: add “blanc” tasks Defects found
Sprint burn down And defects found • The last user story can be tested on the last day of the Sprint • Testing is probably not done at the end of the Sprint • We end up with bugs that are not fixed in this Sprint. • Can we go LIVE with this situation?
Sprint burn down And defects found • Solution: a Hardening Sprint • A short Sprint • No new user stories • Only bug fixes and re-testing • Perhaps time to finish documentation? Sprint 4 (3 User stories) Sprint 5 (2 User stories) Go LIVE
User stories • Sprint backlog • Daily stand-up • Sprint burn down • Other ideas
Other ideas? Your opinion matters • Demo versus Acceptance testing? • A demo is not enough as “acceptance test”! • The user representative should do more extensive testing (preferably the day before the Sprint Review) • Create a “finished user story” list, and add “user acceptance testing passed” notes. US-25504 Document viewer 2 story points Q.C. Passed 25504 U.A.T. Passed 25504
Other ideas? Your opinion matters! • User Stories that do not deliver a UI (e.g. web services) should we always deliver a “test app” for testing purposes. • Definition of done: • Task: tested by developer (unit & integration tests) • User story: functionally tested, no significant defects left • Defect: resolved by developer, re-tested and closed by tester • …
Other ideas? Your opinion matters! • What did I forget? • What was unclear? • … With special thanks to Syed Rayhan, who reviewed this presentation. Take a look at his presentation on ScrumAlliance.org: “A practical guide to implementing Agile QA process on Scrum Projects”
