I need some valid/invalid test data to test the following:
I am testing a web-based financial application written in .NET technologies. It has a SQL Server back-end. I am testing the UI/Functionality of the application and testing different user profiles, administrator pages, and many financial data reports that are in different formats like PDF, CSV, etc. There are many search parameters for reports based on "Date Range", like data generated Today, yesterday, current month, etc. I can't test all combinations of search parameters combination because it is time consuming.
What are some ways to do Negative scenario testing that can help me find vulnerabilities of the application? I want to test: Input boxes that accept Alpha-numeric characters, test Radio buttons, check-boxes, URL manipulation testing, etc.
