high-level checklist and high-level defects

[translation]

"Our development team receives a set of unit test scripts, like a high-level checklist. Development is done only when the checklist is done," he says. "This way, we make sure we don't push high-level defects from development into the test environment."


Could anyone tell me what do these two phrases mean in the context above??? Thanks a lot!!!

Presumably, the checklist is designed to stop errors entering at an important stage, that would then go through to later stages. Being high-level, they would be checking things at the very heart of the development project.
