21.5. Summary

• A fixture acts as a bridge between a Fit table and a system under test.

• We aim to keep fixtures as simple as possible, with minimal knowledge encoded in them of how the system under test works.

• A fixture for a table of type ColumnFixture is a subclass of fit.ColumnFixture, which defines (1) a public instance variable for each given column that is labeled in the header row of a table; (2) a public method for each calculated column in the table. Usually, this method will use the instance variable values to make a call into the system under test. The result of this fixture method is compared against the expected value in the calculated column.

• Camel casing removes spaces from a label to create a valid Java identifier.
