Most testing was done by the QAteam
manually or
Play / record automationThrough the GU I
Based on the V-modelUnit tests were sporadic
Developers knew little abouttesting

Unit tests are the base layerProvide the fastest feedbackBest RO I
Middle layerbecomes functional regressiontests
GUI layerMay be partially automatedMostly exploratory testing

With frequent iterations delivered totesting, how can testers test incomplete
code?Stories must be defined in terms of business value.Stories should not span iterations.
Testers may need to help with story definition.There will always be gaps. ± Testers need to learn and adapt as they find them.

Without the time devoted to completetesting, how do we know when testing is
done?Testing must be prioritized just like stories.Bug metrics also provide an indicator of completeness.A good tester is never done.

S ome have declared that agile teamsshouldn t track bugs and just fix them as
soon as they are found.This works well when you are testing in Dev.Ideally , bugs will be fixed right away , but somemay be deferred.Ultimately , bugs can be prioritized with stories.

With frequent iterations, we need to retestoften. And unit tests aren t enough. How
do we get effective user-level regressiontests?
You don t necessarily need to do a full regressiontest with each iteration. You may run parts in eachiteration cycling through.But you ll still need some level of automated user-level regression tests.
