There are three ways to create a data-driven test: use data from a flat file, use data from a data table, or use data from a database.
Flat File – Data must be saved in a pre-determined format and is read from the file using file manipulation commands and assigned to variables.
Data Table – Similar to the flat file method but data is usually stored in a Microsoft Excel file.
Database – Similar to the previous methods except test data is saved in the database.
