 GreaterThanConstraint

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

 InstanceOfTypeConstraint InstanceOfTypeConstraint is used to test that an object is of the same type provided or derived from it.

 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

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

 NoItemConstraint NoItemConstraint applies another constraint to each item in a collection, failing if any of them succeeds.

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

 NotConstraint NotConstraint negates the effect of some other constraint

 NotOperator Negates the test of the constraint it wraps.

 NullConstraint NullConstraint tests that the actual value is null

 Numerics The Numerics class contains common operations on numeric _values.

 NUnitComparer NUnitComparer encapsulates NUnit's default behavior in comparing two objects.

 NUnitEqualityComparer NUnitEqualityComparer encapsulates NUnit's handling of equality tests between objects.

 OrConstraint OrConstraint succeeds if either member succeeds

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

 PredicateConstraint`1 Predicate constraint wraps a Predicate in a constraint, returning success if the predicate is true.

 PropertyConstraint PropertyConstraint extracts a named property and uses its value as the actual value for a chained constraint.

 PropertyExistsConstraint PropertyExistsConstraint tests that a named property exists on the object provided through Match. Originally, PropertyConstraint provided this feature in addition to making optional tests on the value of the property. The two constraints are now separate.

 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 RangeConstraint tests whether two _values are within a specified range.

 RegexConstraint RegexConstraint can test whether a string matches the pattern provided.

 ResolvableConstraintExpression ResolvableConstraintExpression is used to represent a compound constraint being constructed at a point where the last operator may either terminate the expression or may have additional qualifying constraints added to it. It is used, for example, for a Property element or for an Exception element, either of which may be optionally followed by constraints that apply to the property or exception.

 ReusableConstraint ReusableConstraint wraps a constraint expression after resolving it so that it can be reused consistently.

 SameAsConstraint SameAsConstraint tests whether an object is identical to the object passed to its constructor

 SamePathConstraint Summary description for SamePathConstraint.

 SamePathOrUnderConstraint SamePathOrUnderConstraint tests that one path is under another

 SomeItemsConstraint SomeItemsConstraint applies another constraint to each item in a collection, succeeding if any of them succeeds.

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

 StartsWithConstraint StartsWithConstraint can test whether a string starts with an expected substring.

 SubPathConstraint SubPathConstraint tests that the actual path is under the expected path

 SubstringConstraint SubstringConstraint can test whether a string contains the expected substring.

 ThrowsConstraint ThrowsConstraint is used to test the exception thrown by a delegate by applying a constraint to it.

 ThrowsExceptionConstraint ThrowsExceptionConstraint tests that an exception has been thrown, without any further tests.

 ThrowsNothingConstraint ThrowsNothingConstraint tests that a delegate does not throw an exception.

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

 Tolerance The Tolerance class generalizes the notion of a tolerance within which an equality test succeeds. Normally, it is used with numeric types, but it can be used with any type that supports taking a difference between two objects and comparing that difference to a value.

 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 modifies the order of evaluation because of its precedence.

 XmlSerializableConstraint XmlSerializableConstraint tests whether an object is serializable in xml format.

 ConstraintStatus ConstraintStatus represents the status of a ConstraintResult returned by a Constraint being applied to an actual value.

 ToleranceMode Modes in which the tolerance value for a comparison can be interpreted.

 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 , or .

 ComparisonConstraint Abstract base class for constraints that compare _values to determine if one is greater than, equal to or less than the other.

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

 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 , or a .

 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 PathConstraint serves as the abstract base of constraints that operate on paths and provides several helper methods.

 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 StringConstraint is the abstract base for constraints that operate on strings. It supports the IgnoreCase modifier for string operations.

 TypeConstraint TypeConstraint is the abstract base for constraints that take a Type as their expected value.

 IConstraint Interface for all constraints

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