Transaction not mined when running multiple unit tests (PyEthereum21Backend)
- Version: 0.1.0b26
- Python: 3.6
- OS: linux
Suppose the following django project structure:
- api
- tests.py
- client
- tests.py
Also suppose the following TestCase setup for both test files:
def setUp(self):
# Retrieve a fresh client copy
self.client = MyClient(
provider=self.provider, ...
)
super().setUp()
def tearDown(self):
# Revert to the clean state for every test case
self.eth_tester.revert_to_snapshot(self.clean_state_snapshot)
super().tearDown()
@classmethod
def setUpTestData(cls):
"""Only once setup"""
cls.eth_tester = EthereumTester(backend=PyEthereum21Backend())
cls.provider = EthereumTesterProvider(cls.eth_tester)
cls.web3 = Web3(cls.provider)
# deploying smart contracts etc ...
cls.clean_state_snapshot = cls.eth_tester.take_snapshot()
Below is the output of running each TestCase on its own:
# client.tests output

Preserving test database for alias 'default'...
Everything looks ok.
The problem appears when I try to run both test cases at once, using a single python3 manage.py test command.
What will happen is that inside my code, a call to web3.eth.waitForTransactionReceipt will always timeout or, a call to EthereumTester.get_transaction_receipt will always raise a TransactionNotFound
Below is the output of executing both test cases together, and me pressing ctrl+c to terminate when the call to web3.eth.waitForTransactionReceipt blocks ( setting the timeout to 1 second for example will just make all my unit tests fail )
