+# Tests:
+
+## Running Tests
+
+Our projects use both **`pytest`** and **`unittest`** frameworks.
+You can run tests using either method.
+The **`-vvv`** flag is used for **verbosity**, which provides more detailed output and is very helpful for debugging.
+
+### To run all tests, use one of the following command:
+* **Using Pytest:**
+    ```bash
+    pytest unit -vvv
+    ```
+
+* **Using Unittest:**
+    ```bash
+    python3 -m unittest discover unit -vvv
+    ```
+
+### Running a Subset of Tests
+Specify the directory containing your desired tests. For example, to run tests in `my_test_dir`:
+
+```bash
+pytest unit/my_test_dir -vvv
+# OR
+python3 -m unittest discover unit/my_test_dir -vvv
+```
+
+## Adding New Unit Tests
+
+1. **Create a Test Folder**  
+   Inside the `unit` directory, create a folder for your new test. This folder should contain:
+   - All source/header files needed for the test
+   - `BUILD`
+   - A python test script
+   - `__init__.py`
+
+2. **Creating the BUILD File**
+    - Make sure that all failing test targets get the `"manual"` tag. For example:
+    ```
+    # This is a test I expect to fail
+    codechecker_test(
+        name = "codechecker_fail",
+        tags = [
+            "manual",
+        ],
+        targets = [
+            "test_fail",
+        ],
+    )
+    ```
+
+2. **Creating the Test File**  
+    - Your test script must follow the naming convention:
+        ```text
+        test_*.py
+        ``` 
+    - At the top of your test file, include the following snippet to correctly handle module imports:
+        ```python
+        from common.base import TestBase
+        ```  
+    - Create your test class by extending `TestBase` and implement your test methods.
+> [!WARNING]
+> You should include this line in your test class, this sets the current working directory:
+> ```python
+> __test_path__ = os.path.dirname(os.path.abspath(__file__))
+> ```
+
+**For a test template look into unit/template**
