NUnit 3.13.2 - April 27, 2021

This release fixes a new issue with the FixtureLifeCycle attribute where IDisposable test fixtures were not being disposed properly. As always, @​gleb-osokin has been a great help with this new feature.

It also fixes a long-standing performance issue with CollectionAssert.AreEquivalent and the CollectionEquivalentConstraint when comparing large collections. The deep comparison that NUnit performs on the two collections will always have a worst case bound of O(n^2) but we have optimized it so that the majority of use cases will be closer to O(n).

We've also made significant optimizations to the OR filters for selecting tests using their full name. This dramatically improves test performance for large code bases that use dotnet test. Thanks to @​pakrym for his help with this.

Issues Resolved

• 2799 CollectionAssert.AreEquivalent is extremely slow
• 3589 File headers, copyrights, and licenses
• 3773 IDisposable not working with InstancePerTestCase
• 3779 Obsolete AreEqual methods with nullable numeric arguments for 3.13
• 3784 Build the v3.13-dev branch
• 3786 NUnit with dotnet test results in O(n^2) filtering complexity
• 3810 Enable deterministic build
• 3818 AppVeyor failing to build v3.13-dev branch PRs
• 3832 Deploy v3.13-dev branch builds to MyGet

NUnit 3.13.1 - January 31, 2021

This release addresses several misses with the new FixtureLifeCycle attribute, switches to using SourceLink and NuGet snupkg packages for debugging into NUnit from your unit tests. It also addresses issues with the time format of ignored and explicit tests in the test results file.

Issues Resolved

• 2339 Wrong date format in Ignored TestFixtures
• 3715 FixtureLifeCycle(LifeCycle.InstancePerTestCase) Not working with TestFixtureSource
• 3716 Assembly level FixtureLifeCycle(LifeCycle.InstancePerTestCase) doesn't work
• 3724 Test start and end time should end with Z
• 3726 Assert EqualTo().Within().Seconds does not work with DateTimes in NUnit 3.13
• 3729 AppVeyor builds failing
• 3736 AreEqual.Within throws on failure with non-numeric types
• 3743 Parametrized tests do not respect FixtureLifeCycle.InstancePerTestCase
• 3745 After upgrading to NUnit 3.13.0 the debugger enters NUnit code despite having checked "Enable Just My Code"

NUnit 3.13 - January 7, 2021

The FixtureLifeCycle attribute has been added to indicate that an instance for a test fixture or all test fixtures in an assembly should be constructed for each test within the fixture or assembly.

This attribute may be applied to a test fixture (class) or to a test assembly. It is useful in combination with the Parallelizable Attribute so that a new instance of a test fixture is constructed for every test within the test fixture. This allows tests to run in isolation without sharing instance fields and properties during parallel test runs. This make running parallel tests easier because it is easier to make your tests thread safe.
