ReSharper C++ 2022.1: Updates for Unit Testing and Unreal Engine
ReSharper C++ 2022.1 is now available! It mainly addresses quality and performance issues but also brings a lot of updates for unit testing and Unreal Engine and improves the handling of implicit constructor calls.
The brand new build is available on our website, and all of our tools for Visual Studio can be downloaded via the Toolbox App.
As you may know, ReSharper C++ is the backend of Rider for Unreal Engine, which is currently graduating the preview phase and is available in the new release of Rider. Give it a try and enjoy the familiar Unreal Engine features on all three major platforms!
ReSharper C++ 2022.1 introduces a brand new way to quickly consult the Unreal Engine documentation to get the details of a class, symbol, or function. You can now click Read more in the Quick Documentation pop-up (
Ctrl+Shift+F1) to open the corresponding page in your browser.
We’ve improved how the Rename refactoring handles the Unreal Engine interface classes. When renaming interfaces, both the
I classes will be renamed accordingly.
ReSharper C++ now substitutes the parameter names when you generate a member function signature from the Unreal Engine delegate.
You can now also generate delegate functions when the
ThisClass typedef is used.
As this is a quality-focused release, we’d like to highlight some of the important Unreal-related fixes we’re delivering in this release:
- The Unreal Engine 5 built-in preprocessor macros are now supported in the
- ReSharper no longer suggests the recent C# features that are not applicable in the
.Target.csfiles on Unreal Engine 4.
- ReSharper C++ now reads the list of valid reflection specifiers directly from the version of Unreal Engine which is currently in use, so it only offers you applicable items in code completion and displays up-to-date documentation.
- There are no more issues caused by the
MARK_PROPERTY_DIRTY_FROM_NAMEpush model macros – ReSharper C++ now is aware of entities generated by the replication system, such as the
The Unreal Engine testing framework is now supported! ReSharper C++ discovers Unreal Engine unit tests and adds the corresponding action indicators next to each test in the editor to run or debug the test or the whole test suite. In the Unit Test Sessions window, you can review the results of the tests, and rerun failed, all, or specific tests.
Please note that there are a few known issues. For example, since
StressFilter is ignored by Unreal Engine, ReSharper C++ doesn’t support stress tests. Spec tests and tests with the
‘ symbol are not supported either.
The new version of the Catch2 unit test framework brings significant changes. It’s now split into multiple headers and has a statically compiled library as its distribution model. This means you now have to include several headers, but the compilation time is improved. If you’d like to check out the updated Catch2 unit test framework, ReSharper C++ 2022.1 has full support to help you do so.
ReSharper C++ 2022.1 also includes updates for the latest releases of GoogleTest, Boost.Test, and doctest, as well as various unit testing fixes.
ReSharper C++ is now better at handling implicit constructor calls, allowing you to find usages and navigate to the called constructor in more cases, including the following:
- standard (
make_shared) and Unreal-specific (
MakeUnique) smart pointer creation functions.
emplace-like container methods.
static_castand c-style cast expressions.
ReSharper C++ now also shows you an overloading warning when an
emplace-like function is called with incorrect arguments.
We’ve improved the multiline generation of boilerplate code for aggregate initialization using C++20 designated initializers. This feature was introduced in the previous release. You can now invoke completion on the next line if you want to see each initializer on a new line.
There are a few formatting updates:
- ReSharper C++ now treats the C++20
requires-expressions correctly, allowing you to configure spaces formatting via the Around ‘->’ in trailing return types option.
- You can now use the new Line feed at the end of file option to control adding or removing a blank line from the end of files.
Those are all the highlights for today! The full list of fixed issues is available in our issue tracker. In addition, more changes are coming from the ReSharper platform; for example, you can now autodetect syntax style settings for C# files.
We encourage you to give ReSharper C++ 2022.1 a try. If you have an active subscription, you can update today. Otherwise, we invite you to start your free 30-day trial to check out the new features and share what you think!
