Testing the functionality with more test cases becomes laborious as the functionality grows. For multiple sets of data (test cases), you can execute the test once in which you can figure out for which data it has failed and for which data, the test has passed. This feature is available in the WinRunner with the data driven test where the data can be taken from an excel sheet or notepad.
An application has to be tested with multiple sets of data.The automation test script written for one input can be used for number of inputs using DDTin WINRUNNERThe test script has to be converted into DDT by creating a corresponding data table with the sets od data you want to test.
In DDt we have functions to open and to close the table.They are DDT_OPEN(); And DDT_CLOSE();
A table can be openned in READ or READ WRITE mode..
We want to test multiple sets of data so we use TSL function
for loop.
We can retrive the data from a particular row by using the ROW_COUNT(); function.
It is typically an application-independent automation framework designed to process our tests. These tests are developed as data tables using a keyword vocabulary that is independent of the test automation tool used to execute them. This keyword vocabulary should also be suitable for manual testing.
