CSV Test Runner

Creating custom Test Runner based on TestNG

In java domain TestNG provides one of the most popular testing framework. You can find hundreads of documents which tutor you about using TestNG. But if you can model your test scenarios and results other than java programming it will be more convenient specially if quality analyzing or testing team is not more into programming.

TestNG provides several hooks and programmable API for extendability. Here I am going to show you how to implement very simple custom test runner utilizing such features in TestNG.

CSV Test Runner

The basic concept of this test runner is implementing actions and calling them with many combination of parameters and validating results. Ex We can validate "Add" functionality with many test cases - for different inputs and results. So same test code can be used in several test cases.

Specification

In this project test cases are defined in a csv file.

Format of test csv

ID|ACTION|PARAM-1|PARAM-2....|PARAM-N

ID	unique id for the test
ACTION	name of the test
PARAM-1..PARAM-N	parameters

1,Add,1,5,6

So we are validating Add function which should return 6 after adding 1 and 5.
