You can use ATS for testing your data within your application. You can use a datasheet (Excel) with you different data records within one test scripts. The test script will test every single record. For example:
Amount Price Outcome
10 2.50 25
5 1 5
The Excel sheet has in this case two records. The same test script will automatically run two times using the records data. If you have 100 records it will run a hundred times. You can even use the column ‘Outcome’ to check if the calculation between the column ‘Amount’ and ‘Price’ is ok.
