API

contraint

This function returns a Constraint object.

A constraint is basically a wrapper around a predicate function, allowing to check values with this predicate function (in a given context passed by a Report object).

constraints

This function returns a Constraints object which is basically a list of constraints, which can all be checked on the same value/report with the checkAll function.

failure

This function returns a Failure object. A failure is created each time a constraint predicate returns a falsey value. The failure is always added to the report passed to the constraint check function.

report

This function returns a Report object, which is basically a list of failures. Reports can be combined to import all the failures of several reports into a single one.
