contract("VyperStorage", (accounts) => {
  before(() => engine.start())
  after(() => engine.stop())

  it("...should store the value 89.", async () => {
    const storage = await VyperStorage.new()

    // Set value of 89
    const receipt = await storage.set(89)
    // Get stored value
    const storedData = await storage.get()
    assert.equal(storedData, 89, "The value 89 was not stored.")
  })
})

if request method is eth_call, then this Lib re-request eth_sendTransaction with same params, for getting traceLogs. so that, in using this coverage tool, more gas is consumes. may out of gas error a lot of happen.
