NUnitLite 1.0

NUnitLite Version 1.0 - September 13, 2013

NUnitLite is a small-footprint implementation of much of the current NUnit framework. It is distributed in source form and is intended for use in situations where NUnit is too large or complex. In particular, it targets mobile and embedded environments as well as testing of applications that require "embedding" the framework in another piece of software, as when testing plugin architectures.

This file provides basic information about NUnitLite. For more info see the NUnitLite web site at http://nunitlite.com.

COPYRIGHT AND LICENSE

NUnitLite is Copyright 2004-2013, Charlie Poole and is licensed under the MIT license.

A copy of the license is distributed with the program in the file LICENSE.txt and is also available at http://www.opensource.org/licenses/mit-license.php.

NUnitLite is based on ideas in NUnit, but not on the NUnit implementation. In addition, some code developed in NUnitLite was subsequently contributed to the NUnit project, where it is available under the NUnit license. Subsequently, some (but not all) of the newer NUnit features were ported back to NUnitLite.

ASSERTS

The programmer expresses expected test conditions using the Assert class. The existing functionality of most current NUnit Assert methods is supported, but the syntax has been changed to use the more extensible constraint-based format. The following methods are supported:
Assert.Pass
Assert.Fail
Assert.Ignore
Assert.Inconclusive
Assert.That
Assert.ByVal
Assert.Throws
Assert.DoesNotThrow
Assert.Catch
Assert.Null
Assert.NotNull
Assert.True
Assert.False
Assert.AreEqual
Assert.AreNotEqual
Assert.AreSame
Assert.AreNotSame

ASSUMPTIONS

The programmer may express assumptions in the test using Assume.That() A failure in Assume.That causes an Inconclusive result.

CONSTRAINTS

NUnitLite supports most of the same built-in constraints as NUnit. Users may also derive custom constraints from the abstract Constraint class. The following built-in constraints are provided:
AllItemsConstraint
AndConstraint
AssignableFromConstraint
AssignableToConstraint
AttributeConstraint
AttributeExistsConstraint
BinarySerializableConstraint (not available on compact framework)
CollectionContainsConstraint
CollectionEquivalentConstraint
CollectionOrderedConstraint
CollectionSubsetConstraint
ContainsConstraint
DelayedConstraint
EmptyCollectionConstraint
EmptyConstraint
EmptyDirectoryConstraint
EmptyStringConstraint
EndsWithConstraint
EqualConstraint
ExactCountConstraint
ExactTypeConstraint
ExceptionTypeConstraint
FalseConstraint
GreaterThanConstraint
GreaterThanOrEqualConstraint
InstanceOfTypeConstraint
LessThanConstraint
LessThanOrEqualConstraint
NaNConstraint
NoItemConstraint
NotConstraint
NullConstraint
NullOrEmptyStringConstraint
OrConstraint
PredicateConstraint
PropertyConstraint
PropertyExistsConstraint
RangeConstraint
RegexConstraint (not available on compact framework)
ReusableConstraint
SameAsConstraint
SamePathConstraint
SamePathOrUnderConstraint
SomeItemsConstraint
StartsWithConstraint
SubPathConstraint
SubstringConstraint
ThrowsConstraint
ThrowsNothingConstraint
TrueConstraint
UniqueItemsConstraint
XmlSerializableConstraint (not available on compact framework 1.0)

Although constraints may be created using their constructors, the more usual approach is to make use of one or more of the NUnitLite SyntaxHelpers. The following helpers are provided:

Is: Not, All, Null, True, False, Positive, Negative, NaN, Empty, Unique,
EqualTo, SameAs, GreaterThan, GreaterThanOrEqualTo, LessThan, LessThanOrEqualTo,
AtLeast, AtMost, TypeOf, InstanceOf, AssignableFrom, AssignableTo,
StringContaining, StringStarting, StringEnding, StringMatching,
EquivalentTo, SubsetOf, BinarySerializable, XmlSerializable,
Ordered, SamePath, SamePathOrUnder, InRange

Contains: Substring, Item

Has: No, All, Some, None,Exactly, Property, Length, Count, Message, InnerException, Member, Attribute

Tests are loaded as a tree structure of suites, fixtures and test cases. Each fixture contains it's tests. Tests are executed in the order found, without any guarantees of ordering. A separate instance of the fixture object is created for each test case executed by NUnitLite. The embedded console runner produces a summary of tests run and lists any errors or failures. It can also save an XML representation of the test results.

USAGE

NUnitLite is not "installed" in your system. Instead, you should include nunitlite.dll in your project. Your test assembly should be an exe file and should reference the nunitlite assembly. If you place a call like this in your Main
new TextUI().Execute(args);
then NUnitLite will run all the tests in the test project, using the args provided. Use -help to see the available options.

DOCUMENTATION

NUnitLite uses the NUnit.Framework namespace, which allows relatively easy portability between NUnit and NUnitLite. Currently, there is no separate set of documentation for NUnitLite so you should use the docs for NUnit 2.6 or later in conjunction with the information in this file.
