ReSharper 10 EAP 3: Continuous Testing and ReSharper Build

ReSharper 10 Early Access Program goes on and today we’ve prepared a new build highlighted with major features in ReSharper and dotCover.


ReSharper Build

ReSharper Build is a brand new ReSharper 10 feature that originated from an internal tool that the team used to build ReSharper itself. ReSharper Build is an out-of-process incremental build tool that can take advantage of multiple processes, visualizes different kinds of project build status, and is optimized for large solutions with lots of dependencies.
ReSharper Build & Run tool window

At this point ReSharper Build supports most .NET project types available in Visual Studio, except for Web Sites and ASP.NET 5 applications. Unmanaged C++ can be built using ReSharper although not all features will be available in this case. If you choose to use ReSharper Build and the solution you’re going to build is not supported (or contains projects that are not supported), ReSharper Build will automatically switch to Visual Studio’s native build process.

Note that ReSharper Build is off by default. In order to switch to ReSharper Build instead of Visual Studio’s native build process, go to ReSharper | Options | Tools | ReSharper Build and select ReSharper Build.

We’ll follow up shortly with a separate detailed blog post on the ins and outs of ReSharper Build.

Code style and configuring inspections

ReSharper 10 EAP 3 comes with a set of changes aimed to simplify configuration of and complying with code style settings.

For example, inspection severity can now be configured right from the Alt+Enter menu, without using a modal window:

Find similar issues modal window is now used only for searching in a custom scope. All default scopes, such as solution, project and file, can be applied right from the ALt+Enter menu.

A part of code style settings can now also be configured without leaving the Alt+Enter menu:

Additionally, there are new code inspections with quick-fixes that detect explicit or implicit access modifiers for types and type members, let you use a pre-configured order of modifiers, and help you join or separate attributes in a section.

Other changes

On another note, there are also changes related to TypeScript and JavaScript, such as improved TSX support (though still not final) and JSX support in plain .js files.

If you’re interested, here’s a detailed list of fixes that made it into ReSharper 10 EAP 3.


Continuous Testing

If there’s anything that this EAP build proves, it’s that you should never, ever lose hope. dotCover boosts its version to 4.0 and reveals a preview of Continuous Testing.
Starting a Continuous Testing session
Following an initial code coverage analysis of your solution, dotCover then tracks your code changes, figures out which tests are affected by them, and then it can re-run the affected tests as soon as you hit Save, or use a different strategy of reacting to code changes.

We’ll write more about the way Continuous Testing is implemented very soon. We know there’s quite a lot of ways to improve the feature but if you’re ready to try it out, please let us know of any issues you’ve had on your first approach.

ReSharper C++

In addition to a set of fixes, the new ReSharper C++ EAP build incorporates the following changes:

  • Usage-aware Go to declaration is now supported in a way similar to the mainline ReSharper.
  • New code inspections are available to detect uninitialized base class, accompanied by a quick-fix to initialize a member/base class.
  • Evaluation of compile-time expressions of floating point types is added.

What’s next?

First of all, make sure you didn’t forget to actually download the new EAP build.

We are expecting more EAP builds coming shortly so stay tuned for further updates.

    Seems that Resharper Buid doesn’t support prebuild and postbuild steps of C++ projects.
    Unfortunately I cannot use it.

    I don’t see how I find the output .
    It is critical in C++ projects since only Output window can tell you where is the problem with templates 🙂

      Sorry for the inconvenience, we’ll investigate the scenario with prebuild and postbuild steps.

      As for the output, doesn’t the ReSharper Build results toolwindow appear in VS?

        Results doesn’t have the ‘Output’ option.
        It has only Error List.

    Is your Continuous Testing feature a fully-fledged and official competing product to NCrunch ?

    If so, that’s great news ! It will certainly make us move to ReSharper Ultimate.

      Like the post says, it’s a preview of Continuous Testing feature. In other words, it is a very early version with many rough edges and things to consider, and I would say that at this point it might not be appropriate to talk about the fully-fledged competition.

      But if you could dedicate some time to try it in action and give us your feedback on how it can be better adjusted to yours and your team’s workflows this will be much appreciated.

        Found the feature request to which it was tied:

        Almost 4 years in the making ! Still, it is better than nothing… It is comforting news that Jetbrains will delve into new territories, considering your new licensing scheme.

        We are already clients of both NCrunch and Resharper, but we will certainly take a look at what the new version of NCover has to offer.

        Thanks and keep up the good work !

          Thank you! Yes, it took us much longer to implement the prototype than we expected(

    Very nice idea but I think you need to spell it out a bit more clearly for those of us who don’t delve too deeply into how Visual Studio works.
    With MSBuild, I watched the Output Window and Error List window (for full rebuilds). They showed Errors and Warnings.

    When I flicked on Build & Run, Error List stayed the same no matter what changes I made in the code. It is only when I found the “Showing build results after build completed option” and changed it to “Only if errors or warnings received” (from Only if errors received) that I first saw the Build Result page.
    Without doing this, and in a project with Warnings but not Errors, it appears that it doesn’t work. The default should have been to set to show the same as MSBuild/Error List would have shown IMHO.

    Also there is a Continuous Test button at the bottom right of the status bar. How do I get rid of that horrid thing? Even turning Enable Unit Testing off in the Options doesn’t get rid of it! Please add an option to hide it so I can have what I had previously.
