What is Rasta and RSpec

 Rasta is a keyword-driven test framework using spreadsheets to drive testing.

It’s loosely based on FIT, where data tables define parmeters and expected results. The spreadsheet can then be parsed using your test fixtures.

For the underlying test harness, Rasta uses RSpec so in addition to reporting results back to the spreadsheet you can take advantage of RSpec’s output formatters and simultaneously export into other formats such as HTML and plain text.

RSpec is a testing tool for Ruby, created for behavior-driven development (BDD). It is the most frequently used testing library for Ruby in production applications. Even though it has a very rich and powerful DSL (domain-specific language), at its core it is a simple tool which you can start using rather quickly.
