Example of using handleTestFn to make you Web3js function calls with truffle and ganache-cli.

handleTestFnExample.js

    async function handleTestFn(method, inputs) {
      try {
        return  await method(...inputs)
      } catch(e) {
        return e.receipt
      }
    }

    it('should fail to create an event because eventName is not a string', async function () {
      let op1 = await handleTestFn(this.Contract.createEvent, [123456, _eventDescription, _eventWebsite, _eventDate, _location, { from: mainAccount }])
      assert.equal(op1.status, hex.fail, 'TX status should complete')

      let CreatedList = await handleTestFn(this.Contract.getMyCreatedEvents.call, [4,1])
      assert.deepEqual(convertBigNumArr(CreatedList), ['0', '0', '0', '0'])

      let EventList = await handleTestFn(this.Contract.getAllEvents.call, [4, 1])
      assert.deepEqual(convertBigNumArr(EventList), ['0', '0', '0', '0'])
    })
