Testing with tape and selenium-webdriver (probably wrong)

index.js

test.only('Give error when username and password is missing', function (t) {
  t.plan(1);
  browser.get('http://localhost:3000/');
  browser.findElement({ className: 'login__submit' })
    .click();
  browser.wait(Until.elementIsVisible(By.className('login__error')));
  t.ok(true);
  browser.quit();
});

/*
