Greenfield project

A “greenfield” project means a new software development project or initiative with no prior codebase or legacy system in place, which gives the development team the freedom to design processes and choose tools without the constraints of legacy architecture.

The term originates from the concept of building on undeveloped land, and is contrasted by “brownfield” projects, which involve working with existing systems or codebases, and processes and tools needed to accommodate or integrate with existing components. 

A project starting from scratch with no existing constraints, legacy code, or established testing practices, where a tester can recommend approaches and shape quality from the ground up.
