What are the major features
- Added support for Windows Phone 8 test projects, both using the Visual Studio 2010 test harnass, as well as the new MSTest based framework introduced in Visual Studio 2012 Update 2 (#12470)
- Added support for AggregateExceptions in .NET 4.0 or newer so that aggregated exceptions are treated the same way as normal exceptions. This also allows you to use Should(Not)Throw() to assert a specific exception has occurred (or not), even if it is wrapped in an AggregateException (#12482).
- ShouldBeEquivalent() will attempt to report all differences rather than just the first one. It also supports nested dictionaries (#12472).
- By default the order of items in (nested) collections is ignored while asserting the equivalency of two object graphs. You can override this using the WithStrictOrder()/WithStrictOrderFor() options, with or without a specific path or predicate. Notice that for performance reasons, collections of bytes are still compared in exact order (#12484).
What other improvements are new
- Added support for asserting a method is decorated with a certain attribute (by Nathan Roe)
- Added BeWritable() to the property info assertions .
- XName support for all XML-related assertiosn (#12453 by Igor Khavkin)
- Added Should().BeApproximately() for decimal values.
- Added support for ShouldNotThrow() on Func<Task> so that you can verify that asynchronous functions threw a task (by Igor Khavkin)
- Ensured that all reference type assertions inherit from ReferenceTypeAssertions so that they all share some basic methods like (Not)BeNull.
- Added support for string.Should().NotStartWith() and string.Should().NotEndWith(). Also added the case-insensitive versions of them. (#12441)
- Allowed adding, removing and/or reordering the steps the EquivalencyValidator executes while comparing two object graphs for structural equality.
- By default, the exception message assertions are based on wildcards and case-insensitive. The ComparisonMode enum has been marked obsolete.
Bug fixes
- Added catching of FileLoadExceptions so AttributeBasedFormatter will not crash on certain circumstances.
- Made test framework detection based on assembly scanning case insensitive (#12483)
- Fixed a type-mismatch error when two nullable properties were compared using an AssertionRule.
- The method collection.ShouldBeEquivalent() ignored duplicates in the expectation.
- Applied a small improvement by Groostav to collection.HaveCount() because it was counting collections through LINQ Count() even though it has a normal Count property (#12469).
- Comparing a null collection with another null collection will now succeed (#12490)
- When a type was generic, FA wouldn't display its properties in assertion failures (#12492)
- On Mono, the AttributeBasedFormatter sometimes throws a NullReferenceException, but this has been fixed by Frank Ebersoll (#12487).
- During a structural equality check, FA would incorrectly decide to include protected properties in the comparison. This has been fixed now (#12486).
- FA chocked on properties overriden using the new keyword. Now it just tries to be smart about it and select the one which type matches the subject (#12481).
- When a floating point value representing NaN was compared with another approximate value, it didn't throw (#12479).
- Improved the details of any unexpected exceptions during the ShouldThrow() and ShouldNotThrow() methods (#12473).
- Collection.ShouldBeInAscendingOrder() wasn't reporting the correct index if an item appeared out-of-order (#12468).
Breaking changes
- Renamed the Execute.Verification property to Execute.Assertion and introduced an internal AssertionScope.
