 #### Running tests
 
 After the software requirements have been installed you should be able to run the tests with:
 
 ```shell
-task go:test-integration
+task go:integration-test
 ```
 
-This will automatically install the necessary dependencies, if not already installed, and run the integration tests
-automatically.
+This will run the integration tests automatically.
 
-To run specific modules you must run `pytest` from the virtual environment created by Poetry.
+To run specific packages you must run `go test`.
 
 ```shell
-poetry run pytest test/test_lib.py
+go test -v github.com/arduino/arduino-cli/internal/integrationtest/lib
 ```
 
 To run very specific test functions:
 
 ```shell
-poetry run pytest test/test_lib.py::test_list
-```
-
-You can avoid writing the `poetry run` prefix each time by creating a new shell inside the virtual environment:
-
-```shell
-poetry shell
-pytest test_lib.py
-pytest test_lib.py::test_list
-```
-
-#### Linting and formatting
-
-When editing any Python file in the project remember to run linting checks with:
-
-```shell
-task python:lint
-```
-
-This will run `flake8` automatically and return any error in the code formatting, if not already installed it will also
-install integration tests dependencies.
-
-In case of linting errors you should be able to solve most of them by automatically formatting with:
-
-```shell
-task python:format
+go test -v github.com/arduino/arduino-cli/internal/integrationtest/lib -run TestLibUpgradeCommand
 ```
