The Define fixture creates reusable test procedures that can be run by other fixtures. See Fixtures Using Procedures.

We declare the procedure name in the first row of the Define table and write the procedure body as the rest of the table:

|define|changename|
|set|name|Bob|

We can also declare parameters in the first row. This uses the Do Fixture style, where alternating cells make up the procedure name and the parameter names:

|define|check field|fieldname|is|expected|
|check|fieldname|expected|

To invoke the procedure, we use the procedure name in any place where we'd use a fixture or domain method name. The test results include an expandable section showing the details of the procedure execution. This is what it looks like:

when input is⇓ story test fixture check plain test define changename set name Bob define 'check field' fieldname is expected check fieldname expected 'sample domain' changename 'check field' name is Bob define changename set name Bob define check field fieldname is expected check fieldname expected sample domain changename⇓ set name Bob check field⇓ check name Bob name is Bob

define changename set name Bob define 'check field' fieldname is expected check fieldname expected 'sample domain' changename 'check field' name is Bob

then output is

define changename set name Bob define check field fieldname is expected check fieldname expected sample domain changename⇓ set name Bob check field⇓ check name Bob name is Bob
