Apex error – ‘List has no rows for assignment to SObject’
The error “List has no rows for assignment to SObject” occurs when query doesn’t return any rows.
Resolution
While a SELECT normally returns an array/list, these statements are using the shorthand syntax that assumes only one row is returned. What’s not obvious is that it also assumes that exactly one row is returned! Although this is unlikely to occur for Contact, it is highly likely to occur for any custom objects you create, especially when a WHERE statement is used that might return zero rows, such as:
The above code will fail if there is no Player__c record with the matching username. It doesn’t actually return a null. It would be safer to do the following:
It’s one of those situations for which you would not normally think of creating a test, so it’s safer to just avoid the possibility.

If you get more than 1 row and attempt to assign that to your Accountx variable you will get the opposite of your original problem - System.QueryException: List has more than 1 row for assignment to SObject! So one way of guarding against this would be to use Account accountx = [SELECT Id FROM Account LIMIT 1]'. - frup42.
What's not obvious is that it also assumes that exactly one row is returned! Although this is unlikely to occur for Contact, it is highly likely to occur for any custom objects you create, especially when a WHERE statement is used that might return zero rows, such as:
This is resulting in no records being returned and Salesforce throwing the System.QueryException: List has no rows for assignment to SObject. Note that this is unlike some other programming languages where you may expect the query to just set your sObject to null. Salesforce's documentation for System.QueryException states it is thrown when ...
Or maybe it's being passed but it's useless. If you have StandardSetController the Id value in the page URL might be used as filter id (listview), not an id of any particular record. Meaning query will still return 0 rows. What were you trying to do? Maybe just removing that part of condition will help although this list can grow very fast.
This issue can also occur when the user attempts to reconfigure a Primary Quote without Read access to the associated Opportunity. Lack of access to the Opportunity object throws List has no rows for assignment to SObject' since our code queries for the Primary Quote on that opportunity.

Make sure this record is shared with the Docgen Document Template Library to avoid any errors. Steps to fetch ContentVersionId: Open the active template in the Document Template tab (NOT the Docgen Document Template. Add ContentVersionId field to the layout if it is not present already. Go to the Id in Salesforce to check Sharing Settings.

It's a very common mistake to see client devs not do this, and it can lead to serious issues on big orgs. Writing code this way usually lowers C1 complexity, which makes unit tests a lot easier. Having one record gets you 100% coverage and doesn't throw exceptions or have multiple exits.

The class being tested is expecting an Id, but your test is not passing an Id. The issue is on the last line of code in your test class: ItemSetupNewVersionController.itemSetupClone('is.ParentId__c'); enclosing things in single quotes makes it a string, so you're literally passing "is.ParentId__c" to the method you're testing (instead of the id of the record).

Presumably the value sim is of type Car__c.You cannot assign the result of a query that returns anything other than exactly one record to a value whose type is an SObject. In particular, this does not make sense when you're performing a search query with a LIMIT 20 clause.. You should type your variable as a List<Car__c>.
