AllItemsConstraint

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

 AndConstraint AndConstraint succeeds only if both members succeed.

 AndOperator Operator that requires both it's arguments to succeed

 AssignableFromConstraint

 AssignableToConstraint

 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 AttributeExistsConstraint tests for the presence of a specified attribute on a Type.

 AttributeOperator Operator that tests for the presence of a particular attribute on a type and optionally applies further tests to the attribute.

 BinarySerializableConstraint

 CollectionContainsConstraint CollectionContainsConstraint is used to test whether a collection contains an expected object as a member.

 CollectionEquivalentConstraint CollectionEquivalentCOnstraint is used to determine whether two collections are equivalent.

 CollectionOrderedConstraint CollectionOrderedConstraint is used to test whether a collection is ordered.

 CollectionSubsetConstraint CollectionSubsetConstraint is used to determine whether one collection is a subset of another

 CollectionTally CollectionTally counts (tallies) the number of occurences 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 reognized. 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 reognized. Once an actual Constraint is appended, the expression returns a resolvable Constraint.

 ConstraintFactory Helper class with properties and methods that supply a number of constraints used in Asserts.

 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. This allows testing whether a string is contained in a collection or as a substring of another string using the same syntax.

 DelayedConstraint Applies a delay to the match so that a match can be evaluated in the future.

 EmptyCollectionConstraint EmptyCollectionConstraint tests whether a collection is empty.

 EmptyConstraint EmptyConstraint tests a whether a string or collection is empty, postponing the decision about which test is applied until the type of the actual argument is known.

 EmptyDirectoryContraint EmptyDirectoryConstraint is used to test that a directory is empty

 EmptyStringConstraint

 EndsWithConstraint

 EqualConstraint EqualConstraint is able to compare an actual value with the expected value provided in its constructor. Two objects are considered equal if both are null, or if both have the same value. NUnit has special semantics for some object types.

 ExactCountConstraint

 ExactCountOperator Represents a constraint that succeeds if the specified count of members of a collection match a base constraint.

 ExactTypeConstraint

 ExceptionTypeConstraint

 FalseConstraint FalseConstraint tests that the actual value is false

 FloatingPointNumerics Helper routines for working with floating point numbers

 GreaterThanConstraint Tests whether a value is greater than the value supplied to its constructor

 GreaterThanOrEqualConstraint Tests whether a value is greater than or equal to the value supplied to its constructor

 InstanceOfTypeConstraint

 LessThanConstraint Tests whether a value is less than the value supplied to its constructor

 LessThanOrEqualConstraint Tests whether a value is less than or equal to the value supplied to its constructor

 MsgUtils Static methods used in creating messages

 NaNConstraint NaNConstraint tests that the actual value is a double or float NaN

 NoItemConstraint

 NoneOperator Represents a constraint that succeeds if none of the members of a collection match a base constraint.

 NotConstraint

 NotOperator Negates the test of the constraint it wraps.

 NullConstraint NullConstraint tests that the actual value is null

 NullOrEmptyStringConstraint

 Numerics

 NUnitComparer

 NUnitComparer`1

 NUnitEqualityComparer

 OrConstraint OrConstraint succeeds if either member succeeds

 OrOperator Operator that requires at least one of it's arguments to succeed

 PredicateConstraint`1

 PropertyConstraint

 PropertyExistsConstraint

 PropOperator Operator used to test for the presence of a named Property on an object and optionally apply further tests to the value of that property.

 RangeConstraint`1

 RegexConstraint

 ResolvableConstraintExpression

 ReusableConstraint

 SameAsConstraint

 SamePathConstraint

 SamePathOrUnderConstraint

 SomeItemsConstraint

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

 StartsWithConstraint

 SubPathConstraint

 SubstringConstraint

 ThrowsConstraint

 ThrowsNothingConstraint

 ThrowsOperator Operator that tests that an exception is thrown and optionally applies further tests to the exception.

 Tolerance

 TrueConstraint TrueConstraint tests that the actual value is true

 UniqueItemsConstraint UniqueItemsConstraint tests whether all the items in a collection are unique.

 WithOperator Represents a constraint that simply wraps the constraint provided as an argument, without any further functionality, but which modifes the order of evaluation because of its precedence.

 XmlSerializableConstraint

 ToleranceMode

 BasicConstraint BasicConstraint is the abstract base for constraints that perform a simple comparison to a constant value.

 BinaryConstraint BinaryConstraint is the abstract base of all constraints that combine two other constraints in some fashion.

 BinaryOperator Abstract base class for all binary operators

 CollectionConstraint CollectionConstraint is the abstract base class for constraints that operate on collections.

 CollectionItemsEqualConstraint CollectionItemsEqualConstraint is the abstract base class for all collection constraints that apply some notion of item equality as a part of their operation.

 CollectionOperator Abstract base for operators that indicate how to apply a constraint to items in a collection.

 ComparisonAdapter ComparisonAdapter class centralizes all comparisons of values in NUnit, adapting to the use of any provided IComparer, IComparer<T> or Comparison<T>

 ComparisonConstraint Abstract base class for constraints that compare values to determine if one is greater than, equal to or less than the other. This class supplies the Using modifiers.

 Constraint The Constraint class is the base of all built-in constraints within NUnit. It provides the operator overloads used to combine constraints.

 ConstraintExpressionBase ConstraintExpressionBase is the abstract base class for the ConstraintExpression class, which represents a compound constraint in the process of being constructed from a series of syntactic elements. NOTE: ConstraintExpressionBase is separate because the ConstraintExpression class was generated in earlier versions of NUnit. The two classes may be combined in a future version.

 ConstraintOperator The ConstraintOperator class is used internally by a ConstraintBuilder to represent an operator that modifies or combines constraints. Constraint operators use left and right precedence values to determine whether the top operator on the stack should be reduced before pushing a new operator.

 EqualityAdapter EqualityAdapter class handles all equality comparisons that use an IEqualityComparer, IEqualityComparer<T> or a ComparisonAdapter.

 MessageWriter MessageWriter is the abstract base for classes that write constraint descriptions and messages in some form. The class has separate methods for writing various components of a message, allowing implementations to tailor the presentation as needed.

 PathConstraint

 PrefixConstraint Abstract base class used for prefixes

 PrefixOperator PrefixOperator takes a single constraint and modifies it's action in some way.

 SelfResolvingOperator Abstract base class for operators that are able to reduce to a constraint whether or not another syntactic element follows.

 StringConstraint

 TypeConstraint

 IResolveConstraint The IConstraintExpression interface is implemented by all complete and resolvable constraints and expressions.
