Dynamic Variables (Parametrization)

Make a load test with dynamic data.

Just like the Postman, Ddosify supports dynamic variables. Actually, we support all the random methods Postman supports. If you use {{$randomVariable}} on Postman you can use it as {{_randomVariable}} on Ddosify. Just change $ to _ and you will be fine.

For example, to generate fake integers, you can use {{_randomInt}} on URL, header, body or basic authentication. To simulate a realistic load test on your system, Ddosify sends every request with the new random value that corresponds to the variable you provide.

If you wonder, Ddosify uses go-faker library to generate fake data.

Here is the list of all available dynamic variables.
