printer.init();
});
beforeEach(function () {
printer.reset();
});
after(function () {

const expected1 = [1, 2, 3, 4];
const actual2 = tapAppendTo([1, 2], 'a');
const expected2 = [1, 2, 'a'];
// 2 taps -> invoked console.logs 2 times
const expectedLog = [
[[1, 2, 3], 4],
[[1, 2], 'a']

assert.deepStrictEqual(actual1, expected1);
assert.deepStrictEqual(actual2, expected2);
assert.deepStrictEqual(printer.getLog(), expectedLog);
printer.print('I can still log stuff') // console.log is preserved
});
