 There should be a listener function subscribed to the store using `store.subscribe`.
 
 ```js
-(getUserInput) => assert(getUserInput('index').includes('store.subscribe('));
+(getUserInput) => assert(getUserInput('index').match(/store\s*\.\s*subscribe\(/gm));

+(getUserInput) => assert(getUserInput('index').match(/(\s*function\s*)|(\s*\(\s*\)\s*=>)/gm)) 
 ```
