This is a test assignment. We have developed a simple assignment to imitate real system situation. Test assignment should show the candidate ability to system thinking, coding style, and code versioning skills.
Test assignment described feature to implement.
- NodeJS (ExpressJS / LoopBack)
- MochaJS as a testing framework
- Front-end level basic JavsScript experience
- Database (MySQL, MSSQL, PostgreSQL, MongoDB)
As a customer, I would like to upload files and get converted them into Invoices with precalculation.
- A customer prepares CSV file with invoices: the first column is internal invoice id, the second is invoice amount and "due on" date
1,100,2019-05-20
2,200.5,2019-05-10
B,300,2019-05-01
The real-life file includes five thousand rows and includes invalid rows.
- Customer can upload invoice CSV to the system
- System processes file so that every invoice gets the selling price according to the next logic:
Invoice sell price depends on amount and days to the due date. The formula is
amount * coefficient. The coefficient is 0.5 when the invoice uploaded more than 30 days before the due date and 0.3 when less or equal to 30 days.
- Customer can check invoices uploaded to the system and check their selling price.
- Customer can get upload report and understand errors related to CSV file row processing.
