it('should submit the form and lock the node', () => {
            spyOn(alfrescoApi.nodesApi, 'lockNode').and.returnValue(Promise.resolve({}));

            component.submit();

            expect(alfrescoApi.nodesApi.lockNode).toHaveBeenCalledWith(
                'node-id',
                new NodeBodyLock({
                    'timeToExpire': 60,
                    'type': 'ALLOW_OWNER_CHANGES',
                    'lifetime': 'PERSISTENT'
                })
            );
        });

private get nodeBodyLock(): NodeBodyLock {
        return new NodeBodyLock({
            'timeToExpire': this.lockTimeInSeconds,
            'type': this.form.value.allowOwner ? 'ALLOW_OWNER_CHANGES' : 'FULL',
            'lifetime': 'PERSISTENT'
