What are different DDT and aqFile?

[tuanvinh1008]

Hi all,

I am seeing that DDT and aqFile are supported by TestComplete. So what is different and when we use DDT, when we use aqFile?

Thanks,
Vinh

Hi @tuanvinh1008 

Thanks for your message. 

DDT - TestComplete includes special program objects that let you easily access data stored in an Excel sheet, CSV file or in an ADO database table. These objects are called drivers. They are typically needed to perform data-driven tests, however, you can also use them to retrieve data from the mentioned storages.
The DDT object is used to create drivers for ADO database tables

AQFile - The aqFile object allows you to manage files as well as read from and write to text and binary files

https://support.smartbear.com/testcomplete/docs/reference/program-objects/aqfile/index.html

Both docs provide information and examples of how to use them

Hope that helps!

@vinniew thanks for your reply

so which one is better for performance?

[vinniew]

On the performance side I am not certain. 

I am interested in other members views on this mind you.

I would say context around what it is you would like to do may help decide which option is best to use. 

Thanks 

Vincent
