I'm currently in two scrum projects. The team consists of 9 people (5 developers, 3 testers). We work with user stories, story point estimates and two-week sprints. The team has received a great deal of Scrum and delivers reliably finished (Code + Test + Documentation) software. The test automation is up to date, and the CI runs through every day. However, this does not result in enough tasks for the test team.
Nevertheless, we have the following problem:
At the beginning of the sprint it always takes until testable user stories are completed. Therefore, it comes to idle with the testers, because there is nothing to test.
Already taken countermeasures (which could not solve the problem):
Testers begin with the test preparation for all stories
Support testers - where possible - the work of the developers
"Open Issues List" by the team in case someone has nothing to do
Know How Transfer among the testers
Nevertheless, we have not gotten the problem under control so far. Question: Has anyone had similar experiences? What can you do about it? I am grateful for all suggestions!
