How to use the @ember/test-helpers.currentRouteName function in @ember/test-helpers

test('routing helpers', async (assert) => {
    await visit('/foo');

    assert.equal(currentURL(), '/foo');
    assert.equal(currentRouteName(), 'foo');
});

test('visiting /bar', async function(assert) {
  await visit('/bar');
  assert.equal(currentRouteName(), 'bar.index');
});

test('visiting /foo', async function(assert) {
  await visit('/foo');
  assert.equal(currentURL(), '/foo');
  assert.equal(currentPath(), 'foo.index');
  assert.equal(currentRouteName(), 'foo');
});
