+# Testing
+
+Testing is done via the open-source framework [zemu](https://github.com/Zondax/zemu).
+
+## Running tests
+
+First [install yarn](https://classic.yarnpkg.com/en/docs/install/#debian-stable).
+Then you can install the project by simply running:
+```
+make test
+```
+This will run `make install_tests` and `make run_tests`
+
+To run a specific tests (here the send test):
+```
+cd tests
+sudo jest --runInBand --detectOpenHandles src/send.test.js
+```
+
+Make sure you're in the `tests` folder before running `jest` or `yarn test`.
+
+
+## Adding tests
+
+### Zemu
+
+To add tests, copy one of the already existing test files in `tests/src/`.
+You then need to adapt the `buffer` and `tx` variables to adapt to the APDU you wish to send.
+
+- Adapt the expected screen flow. Please create a folder under `tests/snapshots` with the name of the test you're performing.
+- Then adapt the `ORIGINAL_SNAPSHOT_PATH_PREFIX` with the name of the folder you just created.
+- To create the snapshots, modify the `SNAPSHOT_PATH_PREFIX` and set it to be equal to `ORIGINAL_SNAPSHOT_PATH_PREFIX`.
+- Run the tests once, this will create all the snapshots in the folder you created.
+- Put back your `SNAPSHOT_PATH_PREFIX` to `snapshots/tmp/`.
+
+Finally make sure you adapt the expected signature!
+
+### Update binaries
+
+Don't forget to update the binaries in the test folder. To do so, compile with those environement variables:
+```
+make DEBUG=1 ALLOW_DATA=1
+```
+
+Then copy the binary to the `tests/elfs` folder (in this case, compiled with SDK for nanoS):
+```
+cp bin/app.elf tests/elfs/ethereum_nanos.elf
+```
+
+Repeat the operation for a binary compiled with nanoX SDK and change for `ethereum_nanox.elf`.
