Using ASSERT_* macros inside a lambda that returns void (like this callback) will only exit the lambda, not the entire test case. If the assertion fails, the rest of the test in the main thread will continue to execute, potentially leading to confusing results or crashes if subsequent code depends on the assertion. Use EXPECT_* instead, or a mechanism to propagate the failure to the main thread.

                EXPECT_FALSE(technologies.empty())

ASSERT_FALSE is intentional here. I want the assertion to terminate the callback if no technologies are returned, while allowing the test to continue so that the final ASSERT_TRUE(called) reports that the tethering callback was never invoked. This gives us both relevant failure messages.
