System variables

NativeRest uses built-in library to generate sample data, including random names, addresses, email addresses, and much more. You can use these pre-defined variables multiple times to return different values per request.

You can use these variables like any other variable in NativeRest. Their values are generated at the time of execution and their names start with {{, for example {{random.uuid}} or {{date.isoTimeStamp}}.

You can also use shortcut Ctrl + E to open System Variables window.

All NativeRest system variables

The following is a list of system variables whose values are randomly generated during the request/collection run.

Custom random variables

In NativeRest, you can define variables whose values will be chosen randomly from a set of values. Such variables must begin with the prefix random. Values in a line must be separated by commas, spaces are ignored.

# Random city in Spain
random.spainCities = Madrid, Barcelona, Valencia, Seville, Bilbao

Auto-increment variables

NativeRest supports variables that auto-increment each time they are used. In this way, you can dynamically generate number ids for JSON, where each element will have its own ordinal number. Such variables must begin with the prefix sequence. NativeRest has two built-in system variables:

# Built-in NativeRest auto-increment variables with initial values of 0 and 1 respectively.
sequence.number0 = 0
sequence.number1 = 1

You can also declare your variables by specifying an initial integer value in any scope.

# Auto-increment variable with initial value 10
sequence.myCounter = 10

The number of user sequence variables is unlimited. Each can have its own initial value.

Functions

NativeRest, along with system variables, provides a large number of built-in functions. You can perform hash, hmac, base64, random, date, math, string and many other functions.
