[Ethena] HardhatChaiMatchersAssertionError: Assertion error: receipt should not be null #165
Description
Several test in suites across Ethena fail with the error receipt should not be null, which adding delays does not seem to fix. Most cases this fails consistently, but I have observed certain tests where this fails sometimes & passes other times. Running tests together vs. individually does not seem to have an effect.
Steps to Reproduce
We use the test titled testRate_ in EthenaBalancerRateProvider.test.ts to observe the behavior.
1. Setup testing environment for Ethena.
Following steps assume ethena-labs as working directory.
git clone https://github.com/paritytech/scc-testing.git --branch charles/ethena
cd scc-testing
git checkout --detach ce904986c313df704f24488ad85c4af166001dc1
cd ethena-labs
npm install
# Choose depending on your machine
chmod -R +x ./bin/linux
chmod -R +x ./bin/mac2. Put the following environment variables into ethena-labs/.env
# NOTE: update bin path depending on linux vs mac
REVIVE_DEV_NODE_BIN=./bin/linux/revive-dev-node
ETC_RPC_BIN=./bin/linux/eth-rpc3. Launch dev-node & eth-rpc
# NOTE: update bin path depending on linux vs mac

RUST_LOG="info,eth-rpc=debug" ./bin/linux/eth-rpc4. Run the test
npm test -- --network localNode test/staking/EthenaBalancerRateProvider.test.ts --grep "testRate_"Observed Behavior
