Subject: [PATCH 01/23] :umbrella: Add integration tests.

For now, there are 3 tests.
- A test that the window can be opened.
- A test that python code can be executed in a cell.
- A test that a block can be moved.

Do not use your mouse or keyboard during the test !

+Integration tests for OCB.
+
+Every test describes a thing the user might try to do.
+
+Important note:
+Due to a bug in pytest, if an error occurs in a test, pytest might crash and report an error
+that looks like this:
+
+    Windows fatal exception: access violation
+
+    Thread 0x000002a4 (most recent call first):
+    <Stack Trace involving native python libraries related to asyncio>
+
+This behavior is not consistent because the crash depends on the memory layout of the program.
+If this occurs, you can check what the real error is (with the proper error message), by running
+this file directly with:
+
+python ./tests/integration/test_blocks.py

 """
 Integration tests for OCB.
 
-Every test describes a thing the user might try to do.
-
-Important note:
-Due to a bug in pytest, if an error occurs in a test, pytest might crash and report an error
-that looks like this:
-
-    Windows fatal exception: access violation
-
-    Thread 0x000002a4 (most recent call first):
-    <Stack Trace involving native python libraries related to asyncio>
-
-This behavior is not consistent because the crash depends on the memory layout of the program.
-If this occurs, you can check what the real error is (with the proper error message), by running
-this file directly with:
-
-python ./tests/integration/test_blocks.py
+We use xvfb to perform the tests without opening any windows.
+We use pyautogui to move the mouse and interact with the application.
 
+To pass the tests on windows, you need to not move the mouse.
+To pass the tests on linux, you just need to install xvfb and it's dependencies.
+On linux, no windows are opened to the user during the test.
