- In DDT, the scripts are programmed in structured manner and is defined by testdata.
- During execution the Data is supplied to the script through an excel sheet or external files.
- It is used in testing of the computer software to describe testing done using a table of conditions directly as the test inputs and verifiable outputs as well as the process where test environment settings and control are not hard-coded.
- It helps to add the additional inputs to the table when new partitions are discovered or added to the product or system under test.
- Cost wise it is cheap for automation but expensive for manual testing.
