Instead, you want to provide a different dependency that will be used only during tests (possibly only some specific tests), and will provide a value that can be used where the value of the original dependency was used.

### Use cases: external service

An example could be that you have an external authentication provider that you need to call.

                    if (values.length > 1) {
                        permissionSet.add(systemHelper.getSearchRoleByUser(values[0]));
                    }
