[FEATURE]: Tests for server & routing subsystem

[lev2p1]

Feature Category

Testing tooling

Problem Statement

It is necessary to understand whether the routing subsystem is performing its functions works correctly. We plan to wrap all subsystems in tests.

Proposed Solution

Use the path tests/unit to create tests (you can use the ready‑made example in ./routing).

API Design

TEST(ServerTest, TestGet) {
	EXPECT_EQ(x, y);
}
