Useful methods to process tables in Cucumber step definitions

When you accept a table in your Cucumber step definition, that table object will have the cryptic type Cucumber::Ast::Table Show archive.org snapshot . Don't immediately call table.raw to convert it into an array of arrays! Cucumber::Ast::Table has a lot of useful methods for tasks such as:

table.raw

Turn the table into an array of arrays

table.hashes

Convert the table to an array of hashes, where the keys are the table headers from the first row

table.headers

Return only the first row

table.rows

Return all but the first row as an array of arrays – you might prefer table.raw or table.rows_hash

table.rows_hash

Turn a two-columned table into a hash, where the first column is the keys and the second the values

table.transpose

Transpose the table (switch rows <-> columns)

Furthermore…

• Mapping natural language table headers to internal identifiers such as attribute names
• Comparing a table with another table, with pretty diff and all.
