...a suite of tests is run, optimized to execute very quickly. We refer to this suite of tests as commit stage tests rather than unit tests, it is useful to include a small selection of tests of other types at this stage...
Begin the design of your commit test suite by running all unit tests. Later, as you learn more about what types of failure are common in acceptance test runs ... you should add specific tests to your commit test suite to try and find them early on.
Acceptance tests written without developer involvement also tend to be tightly coupled to the UI and thus brittle and badly factored, because the testers don't have any insight into the UI's underlying design and lack the skills to create abstraction layers or run acceptance tests against a public API.
