toThrow() is not implemented in test-runner.

I just checked the test runners, matchers.js and it seems like it hasnt been implemented. It def is needed to test for thrown exceptions.

Happy to accept a PR 👍

In the meantime you can do something like

try {
  something()
  expect(false).toBe(true)
} catch (err) {
  expect(true).toBe(true)
}
