+### Asyncio testing
+
+Tests for `asyncio` are written using `IsolatedAsyncioTestCase` class.
+
+
+```py
+import asyncio
+
+from unittesting import IsolatedAsyncioTestCase
+
+async def a_coro():
+    return 1 + 1
+
+class MyAsyncTestCase(IsolatedAsyncioTestCase):
+    async def test_something(self):
+        result = await a_coro()
+        await asyncio.sleep(1)
+        self.assertEqual(result, 2)
+```

 ## Helper TestCases
 
 UnitTesting provides some helper test case classes,
