javascript - 运行测试用例后清理智能合约存储

Question

在为智能合约运行测试用例时，我想销毁智能合约并重新部署它，或者在运行每个测试用例后重置其状态。测试用例是用 javascript 编写的。这个想法是在 AfterEach 结构中运行代码。

contract("Contract", accounts => {
  let contract;
  let owner = accounts[0];
  let admin = accounts[1];
  let user = accounts[2];

  describe("function1 tests", () => {
    before("Setup contract for each test", async () => {
      contract = await Contract.deployed();
    });

    afterEach("", async () => {
     //code to selfdestruct or reset the state of the contract after 
     //each test
    });

    it("test1", () => {
      //test1 code
    });

    it("test2", () => {
      //test2 code
    });
  });
});

Answer 1

在 beforeEach() 内部

beforeEach('initialize the contract', async function() {
    contract = await Contract.new()
})

这样，对于每个 it 案例，您都会有一个新的 Contract 实例。
