import * as assert from 'uvu/assert';

const add = (a, b) => a + b;

test('add', () => {

  const addFn = snoop(add);

  const anotherAddFn = snoop(add);

  addFn.fn(1, 1);

  anotherAddFn.fn(1, 1);

  addFn.fn(2, 2);

  anotherAddFn.fn(2, 2);

  assert.ok(addFn.called);

  assert.not(addFn.notCalled);

  assert.not(addFn.calledOnce);

  assert.is(addFn.callCount, 2);

  assert.equal(addFn.calls[0].arguments, [1, 1]);

  assert.equal(addFn.calls[1].arguments, [2, 2]);

  assert.is(addFn.calls[0].result, 2);

  assert.is(addFn.calls[1].result, 4);

  assert.not(addFn.firstCall.error);

  assert.not(addFn.lastCall.error);

  assert.ok(addFn.calledBefore(anotherAddFn));

  assert.ok(addFn.calledAfter(anotherAddFn));

  assert.ok(addFn.calledImmediatelyBefore(anotherAddFn));

  assert.not(addFn.calledImmediatelyAfter(anotherAddFn));

});

test.run();
