withMockUser<T> function

Future<T> withMockUser<T>(FutureOr<T> body(), { String username = 'user', List<String> roles = const ['USER'], List<String>? authorities, })

Runs body as a logged-in user and returns its result.

The user is named username (user by default), with the password password, and has the roles roles (USER by default, giving ROLE_USER). Pass authorities instead to give full authority names (SCOPE_read); then roles is ignored. The principal is a User, so principal.username works in expressions.

Spring (Java): @WithMockUser(username = "ada", roles = "ADMIN").

Implementation

Future<T> withMockUser<T>(
  FutureOr<T> Function() body, {
  String username = 'user',
  List<String> roles = const ['USER'],
  List<String>? authorities,
}) {
  final builder = User.withUsername(username).password('password');
  final user = authorities == null
      ? builder.roles(roles).build()
      : builder.authorityNames(authorities).build();
  return withAuthentication(
    body,
    UsernamePasswordAuthenticationToken.authenticated(
      user,
      user.password,
      user.authorities,
    ),
  );
}
