ERPNext Unittest, How to setup?

Hi,

I’ve tried to create simple unittest for custom app.

But when I tried to create Sales Order using make_sales_order, I got LinkValidationError

I know that creating _Test Company, _Test Item and _Test Warehouse - _TC will solve the problem.

My question is
Is there a function or database can be use for creating test data for default ERPNext doctype ?

Error

I’ll :+1: this. Going to start testing some of my custom app. And I don’t see much docs apart from this. Which seems lacking for a huge framework like frappe, to only have one page explaining the basics of testing.

There is a bit more detail doc Frappe - Unit Testing.

But it doesn’t have anything on create test record.

I meant creating test data for default ERPNext doctype.

So in Sales Order DocType it needs _Test Company, _Test Item and _Test Warehouse - _TC

Is there a function or database can be use for creating test data for default ERPNext doctype ?
