I increase time the same way as described in OpenZepplin samples in the test below:

    it("should revert claim drawing with 'Android: bad state'", async () => {
    const [owner, signer1] = await ethers.getSigners();

    let duration = time.duration.seconds(3);
    await time.increase(duration);

    await truffleAssert.reverts(
        android.claimPainting(1),
        'Android: bad state'
    );
});

And it fails with Error: Invalid JSON RPC response: "". How can i fix it? time is imported as const { time } = require("@openzeppelin/test-helpers"); + "@openzeppelin/test-helpers": "0.5.15" in package.json. I also use ethers from hardhat, don't know if this could cause the problem.

You will need to execute Hardhat local node server and try again. "npx hardhat node" Hope this works on your side.

Install web3 and the hardhat-web3 plugin.

npm install --save-dev @nomiclabs/hardhat-web3 web3

Then add the following line to your hardhat config

import "@nomiclabs/hardhat-web3";
