Please add toThrow feature

[ncomerci]

Hello!

Could you please add the functionality to test errors in functions?

expect(() => {
...
}).toThrow()

But assemblyscript does not support error IMO? do you mean throw from ts import function

Here is an example of what I mean:

function someFunction() {
  // ... some code ...
  throw new Error('test')
}

describe('someFunction', () => {
  describe('when some condition is met', () => {
    test('throws an error', () => {
      expect(() => someFunction()).toThrow()
    })
  })

  describe('when some condition is not met', () => {
    test('does not throw an error', () => {
      expect(() => someFunction()).not.toThrow()
    })
  })
})

Similar to the as-pect framework, which is no longer maintained.
