AllItemsConstraint applies another constraint to each
item in a collection, succeeding if they all succeed.

Represents a constraint that succeeds if all the
members of a collection match a base constraint.

AndOperator
Operator that requires both its arguments to succeed
AnyOfConstraint
is used to determine whether the value is equal to any of the expected values.
AssignableFromConstraint
AssignableFromConstraint is used to test that an object
can be assigned from a given Type.
AssignableToConstraint
AssignableToConstraint is used to test that an object
can be assigned to a given Type.
AttributeConstraint
AttributeConstraint tests that a specified attribute is present
on a Type or other provider and that the value of the attribute
satisfies some other constraint.
AttributeExistsConstraint

specified attribute on a Type.

on a type and optionally applies further tests to the attribute.

collections are equivalent.

of each object in one or more enumerations.
ConstraintBuilder
ConstraintBuilder maintains the stacks that are used in
processing a ConstraintExpression. An OperatorStack
is used to hold operators that are waiting for their
operands to be reorganized. a ConstraintStack holds
input constraints as well as the results of each
operator applied.
ConstraintExpression
ConstraintExpression represents a compound constraint in the
process of being constructed from a series of syntactic elements.
Individual elements are appended to the expression as they are
reorganized. When a constraint is appended, it is returned as the
value of the operation so that modifiers may be applied. However,
any partially built expression is attached to the constraint for
later resolution. When an operator is appended, the partial
expression is returned. If it's a self-resolving operator, then
a ResolvableConstraintExpression is returned.
ConstraintResult
Contains the result of matching a against an actual value.
ContainsConstraint
ContainsConstraint tests a whether a string contains a substring
or a collection contains an object. It postpones the decision of
which test to use until the type of the actual argument is known.

or as a substring of another string using the same syntax.

postponing the decision about which test is applied until the
type of the actual argument is known.

values in NUnit, adapting to the use of any provided
,
or .

that operate on paths and provides several helper methods.

its action in some way.
