+.. tab-set::
+
+   .. tab-item:: Bazel (host)
+
+      Run all tests:
+
+      .. code-block:: console
+
+         bazel test //pw_bluetooth_sapphire/host/... \
+           --platforms=//pw_unit_test:googletest_platform \
+           --@pigweed//pw_unit_test:backend=@pigweed//pw_unit_test:googletest
+
+      Run l2cap tests with a test filter, logs, and log level filter:
+
+      .. code-block:: console
+
+         bazel test //pw_bluetooth_sapphire/host/l2cap:l2cap_test \
+           --platforms=//pw_unit_test:googletest_platform \
+           --@pigweed//pw_unit_test:backend=@pigweed//pw_unit_test:googletest \
+           --test_arg=--gtest_filter="*InboundChannelFailure" \
+           --test_output=all \
+           --copt=-DPW_LOG_LEVEL_DEFAULT=PW_LOG_LEVEL_ERROR
+
+   .. tab-item:: Bazel (Fuchsia emulator)
+
+      .. code-block:: console
+
+         bazel run --config=fuchsia //pw_bluetooth_sapphire/fuchsia:infra.test_all
+
+   .. tab-item:: GN (host)
+
+      The easiest way to run GN tests is with ``pw presubmit``, which will install
+      dependencies and set GN args correctly.
+
+      .. code-block:: console
+
+         $ pw presubmit --step gn_chre_googletest_nanopb_sapphire_build
+
+      You can also use ``pw watch`` if you install all the packages and set
+      your GN args to match the `GN presubmit step`_.
