Building and Testing REEF .NET

Prerequisites

  • Windows OS including Windows 8,10,Server 2012 and Server 2016.
  • Same prerequisites as REEF Java (Building REEF Java), which includes:
  • Set the following environment variables:
    • Set M2_HOME environment variable to location of maven installation
    • Set JAVA_HOME environment variable to java installation directory
  • Add the following items to the environment variable PATH:
    • Add the location of the protoc.exe executable in the windows path
    • Add %JAVA_HOME%/bin and %M2_HOME%/bin to the windows path as well
  • Visual Studio 2015 (preferred) or 2013. Most REEF developers use the free Community Edition.
  • NuGet 2.8.6 or later. (Included in VS 2015)
  • xunit.runner.console.2.1.0 package (installing it might require manual restore of NuGet packages).

Instructions

To build and run tests in Visual Studio on local machine:

  1. Open solution .\lang\cs\Org.Apache.REEF.sln
  2. Build solution
  3. Open Test Explorer and add search filter -Trait:Environment to filter out tests which are supposed to run on Yarn. If not filtered out, these tests will fail.
  4. Use "Run All" to run all tests

To build REEF.NET from command line, execute

msbuild .\lang\cs\Org.Apache.REEF.sln

To run .NET tests on local machine from command line, execute

msbuild .\lang\cs\TestRunner.proj

TestRunner.proj already has a filter set up to exclude Yarn tests.

Continuous Integration

We use AppVeyor to run continuous integration for REEF .NET code (i.e. build code and run tests for all pull requests and commits to master branch).

It can be convenient to set up AppVeyor for your fork of REEF repository, for example, to reproduce a test failure which can't be reproduced locally or to get AppVeyor test run results earlier than the official ones.

  1. Log in to AppVeyor using your GitHub credentials.
  2. Go to project creation and select reef repository.
  3. Fine-tune configuration as required at Settings tab of repository; you can enable building pushes to your repository when you're investigating something and disable them when you don't need them.
  4. Edit AppVeyor configuration file as required (by default you'll use the same configuration as REEF build).

To isolate a specific test or group of tests, you can modify test_script section of appveyor.yml. For example, to run only one test Org.Apache.REEF.Tests.Functional.IMRU.IMRUCloseTaskTest.TestTaskCloseOnLocalRuntime modify test_script section as follows:

test_script:
  - cmd: cd .\lang\cs
  - cmd: .\.nuget\nuget.exe restore .\.nuget\packages.config -o .\packages
  - cmd: .\packages\xunit.runner.console.2.1.0\tools\xunit.console.exe .\bin\x64\Debug\Org.Apache.REEF.Tests\Org.Apache.REEF.Tests.dll -method Org.Apache.REEF.Tests.Functional.IMRU.IMRUCloseTaskTest.TestTaskCloseOnLocalRuntime

nuget restore is necessary to install xunit.runner.console package, which by default is installed in TestRunner.proj.
