Angular error running Karma tests: HTML5 mode requires a <base> tag

You can specify your base tag in your index.html <head> like that:

<head>
  <base href="/">
  ...
</head>

Source: from angularjs documentation

You can disable the base tag check by doing the following:

$locationProvider.html5Mode({
  enabled: true,
  requireBase: false
});
