Testing¶

Running Tests¶

bazel test //...

Run a specific target:

bazel test //path/to:target

Force re-execution (skip cache):

bazel test //... --nocache_test_results

C++ Tests¶

GoogleTest is integrated via Bazel. Define test targets using cc_test:

cc_test(
    name = "my_test",
    srcs = ["my_test.cc"],
    deps = [
        "//src:my_library",
        "@googletest//:gtest_main",
    ],
)

Rust Tests¶

Native Rust tests work through rules_rust. Define test targets using the standard Rust test model.

Python Tests¶

pytest-based tests are integrated through Bazel's Python rules.

ITF Integration Testing¶

The Integration Test Framework (ITF) is a pytest-based framework for target-oriented testing. Key characteristics:

• Uses the py_itf_test Bazel macro to define test targets
• Plugin model supports Docker, QEMU, and hardware targets
• Tests declare required capabilities using the @requires_capabilities decorator

See the ITF project documentation for detailed usage.

Coverage¶

Collect LCOV coverage data:

bazel coverage //... --combined_report

• C++: Compiler instrumentation via bazel_cpp_toolchains
• Rust: LLVM-based source coverage

Sanitizers¶

score_cpp_policies provides selectable sanitizer features:

Sanitizer	Purpose
ASan	Address errors (buffer overflow, use-after-free)
UBSan	Undefined behavior
LSan	Memory leaks
TSan	Data races

Enable sanitizers via Bazel select() expressions in your build configuration.
