expectedSupplyAssets behaving differenly locally and in CI-CD pipeline (gitlab)

[codekoriko]

I'm using hardhat to fork the mainnet and run unittest for my api calls and I got an issue when testing the function

export async function getLoanTokenSupplied(
  publicClient: PublicClient,
  marketParam: MorphoMarketParams,
  userAddress: EOAAddress,
): Promise<bigint> {
  return await publicClient.readContract({
    address: leverosAddress,
    abi: LeverosMorphoBlueAbi,
    functionName: 'supplyAssetsUser',
    args: [ marketParam, userAddress]
  })
}

my test as follow

  it('retrieves the amount of loanToken a given user has supplied', async function () {
    await loadFixture(deployLeveros);
    const { userWallet } = await loadFixture(setUpLeveros);
    const publicClient = await hre.viem.getPublicClient();

    const amountSuppliedByUser = await getLoanTokenSupplied(
      publicClient,
      getMorphoMarketParam(leverosParam),
      userWallet.account!.address as EOAAddress,
    )
    expect(amountSuppliedByUser).to.approximately(AMOUNT_LOAN_TOKEN_SUPPLIED, BigInt(147498892026))
  });

The test passes when I run it locally npx hardhat test but the same test fails consistently when running in my CI-CD pipeline on Gitlab, with an assertion error:

AssertionError: expected 10000000147498892026 to equal 10000000000000000000

the morpho function supplyAssetsUser used in that test says in its docstring says:

Returns the expected supply assets balance of user on a market after having accrued interest

Would that consistent 147498892026 discrepancy comes from that accrues interest calculation which somehow behave differently locally and in my CI-CD docker environement?

Hey @codekoriko this issue does not seem related to oracles, am I correct?

[codekoriko]

indeed @MerlinEgalite in that case no oracles involved in my deployment or setup function. I noticed that sometimes I have this few Gwei increase during local testing. That's when I run the test just after doing hardhat clean which delete the cache of EVM calls. The consequence are the chains of calls of my test take more time to execute (and interesting accruing to occur?)
