Building and running tests on Linux, macOS, and FreeBSD

CoreCLR tests

Building

Build CoreCLR on Unix.

Building the Tests

Dotnet CLI is required to build the tests. This can be done on any platform then copied over if the architecture or OS does not support Dotnet.

To build the tests on Unix:

./src/coreclr/build-test.sh

Please note that this builds the Priority 0 tests. To build priority 1:

./src/coreclr/build-test.sh -priority1

Building Individual Tests

During development there are many instances where building an individual test is fast and necessary. All of the necessary tools to build are under coreclr. It is possible to use ~/runtime/dotnet.sh msbuild as you would normally use MSBuild with a few caveats.

!! Note !! -- Passing /p:TargetOS=[OSX|Linux] is required.

Building an Individual Test

./dotnet.sh msbuild src/coreclr/tests/src/path-to-proj-file /p:TargetOS=<TargetOS> /p:Configuration=<BuildType>

Running Tests

The following instructions assume that on the Unix machine:

  • The CoreCLR repo is cloned at /mnt/coreclr

src/coreclr/build-test.sh will have set up the Core_Root directory correctly after the test build.

./src/coreclr/tests/runtest.sh x64 checked

Please use the following command for help.

./src/coreclr/tests/runtest.sh -h

Unsupported and temporarily disabled tests

Unsupported tests outside of Windows have two annotations in their csproj to ignore them when run.

<TestUnsupportedOutsideWindows>true</TestUnsupportedOutsideWindows>

This will write in the bash target to skip the test by returning a passing value if run outside Windows.

In addition:

<DisableProjectBuild Condition="'$(TargetsUnix)' == 'true'">true</DisableProjectBuild>

Is used to disable the build, that way if building on Unix cycles are saved building/running.

PAL tests

Build CoreCLR with PAL tests on the Unix machine:

./src/coreclr/build-runtime.sh -skipgenerateversion -nopgooptimize \
    -cmakeargs -DCLR_CMAKE_BUILD_TESTS=1

Run tests:

./src/coreclr/src/pal/tests/palsuite/runpaltests.sh $(pwd)/artifacts/obj/coreclr/$(uname).x64.Debug

Test results will go into: /tmp/PalTestOutput/default/pal_tests.xml
