Hi, I want to persuade my manager into using Mattermost. However, he asked: How does Mattermost ensure its code quality? How does it ensure bug-free?
I do have checked the open source code and see some tests inside the repository. So I wonder whether that is the whole story, or whether Mattermost have some hidden tests that is not visible in GitHub? Or mattermost has some manual tests (e.g. a tester works everyday to test the product)?
How should I answer my manager?
