When testing transaction signing, there is an option to check transaction hashes on-chain using Blockbook. It is chosen by setting `CHECK_ON_CHAIN=1` environment variable before running the tests.
|
||||||
|
|
||||||
|
```sh
|
||||||
|
CHECK_ON_CHAIN=1 pytest tests/device_tests
|
||||||
|
```
|
||||||
|
|
||||||
To run the tests quicker, spawn the emulator with disabled animations using `-a` flag.
