Fuchsia Bazel SDK Tests

This directory contains tests meant to test the Fuchsia Bazel SDK. These currently require to be in a Fuchsia checkout.

Simple invocation

The simplest way to run them is to call fx build bazel_sdk_tests. This ensures that all pre-requisites are available, ensures hermeticity and incremental build correctness. However, it will run the full test suite every time (i.e. will not allow you to run an individual test).

Custom invocation

Another way is to prepare your Fuchsia build by calling fx build generate_fuchsia_sdk_repository first, then invoking scripts/bazel_test.py. You can use --test_target=<label> to select an individual test target (instead of all of them), or even pass extra arguments using -- <extra_args>, for example:

# Run the full test suite.
scripts/bazel_test.py

# Run a subset of test targets, and change test output.
scripts/bazel_test.py --test_target=:build_only_tests -- --test_output=streamed

For more options, invoke the script with --help.

Direct bazel invocation

Finally, it is possible, on Linux only, to directly invoke bazel test in this directory after some necessary preparation, i.e.:

  • Run fx build generate_fuchsia_sdk_repository to populate pre-requisites from a Fuchsia checkout.

  • Define the LOCAL_FUCHSIA_PLATFORM_BUILD to point to the build directory corresponding to the previous step.

  • Invoke bazel test --config=fuchsia_<cpu> <test_target>, where <cpu> matches the CPU architecture of your Fuchsia build configuration. Note that without this --config parameter, the test suite will fail.

For example:

# Preparation steps (only do this once)
cd /work/fuchsia
fx set core.x64
fx build generate_fuchsia_sdk_repository
export LOCAL_FUCHSIA_PLATFORM_BUILD=$(fx get-build-dir)
cd build/bazel_sdk/tests

# Run the test suite, customize options if needed.
bazel test --config=fuchsia_x64 :tests

Note that this will download random archives from the Internet, and store all build artifacts under your $HOME/.cache/bazel/ directory.

This last method does not work on macOS because the WORKSPACE.bazel hard-codes linux-specific paths to host prebuilt binaries (https://fxbug.dev/124321).
