Simulating data

This article lists and explains all available simulator functions.

In app development, the original data needed to test certain functionality might not be available during the building phase. In such instances, utilizing the simulator is a wise choice. The simulator provides a comprehensive set of functions, capable of generating various data types and pseudo random data.

To access the simulator, unfold Simulation > Simulator in the functionality panel.

Simulator functions

Simulator functions do not differ from other functions in the way you can link, configure or extend them.

Random integer

The randomInteger function generates random integers. You can specify a minimum and/or maximum value for the random integer using the min: and max: options in the input field. The default is 0 to 99999.

Random integer function with minimum and maximum value

Random number

The randomNumber function generates random rational numbers. You can specify a minimum and/or maximum value for the random number using the min: and max: options in the input field. The default is 0 to 1.

Random number generation with minimum and maximum values specified

Random string

With the randomString function you can generate a string of random characters. The default length is 10, but can be set manually by inserting the desired length in the input box.

Random text

With the randomText you can generate random text. Modify the generated text with the parameters listed below to fit your test case.

Parameter	Type	Default	Description
count	Integer	1	Number of "words", "sentences", or "paragraphs"
format	String	plain	Formatting of text as either plain text or html.
paragraph LowerBound	Number	3	Minimum number of sentences per paragraph.
paragraph UpperBound	Number	3	Maximums number of sentences per paragraph.
sentence LowerBound	Number	3	Minimum number of words per sentence.
sentence UpperBound	Number	3	Maximum number of words per sentence.
suffix	String	\n	Line ending, defaults to "\n" or "\r\n" (win32)
units	String	sentences	"paragraph(s)", "sentence(s)", or "word(s)"

Generating template text

Error

The error function can generate an exception for testing purposes or for use in a workflow. Using the parameter customMessage, you can define the error message.

Random object

The function randomObject generates an object with 3 to 7 elements as default. You can set the number of entries with min: and max: .

Generating a pseudo random object

Random array of integers

With randomArrayOfIntegers you can generate an array of integers of length 10. If you desire a different length, insert the length as a number in the input field.

Generating an array of integers with length 2

Random array of numbers

With randomArrayOfNumbers you can generate an array of numbers of length 10. If you desire a different length, insert the length as a number in the input field.

Generating an array of numbers with length 2

Random array of digits

With randomArrayOfDigits you can generate an array of digits (integers below 10) of length 10. If you desire a different length, insert the length as a number in the input field.

Generating an array of digits with length 2

Random array of strings

With randomArrayOfStrings you can generate an array of strings of length 10. If you desire a different length, insert the length as a number in the input field.

Generating an array of strings with length 2

Random array of objects

With randomArrayOfObjects you can generate an array of objects of length 10. If you desire a different length, insert a number in the first input field. Each array entry will contain multiple objects, the number of which you can control with min: and max: in the second input field. The default amount is 3 to 7.

Generating an array of objects with length 2 and 2 objects per entry

Random numeric data

Generate numeric data with the randomNumericData function. In its basic form, the output looks like an array of numbers, but using addTimeAxis: true and timeFormat: 'epoch' (can be either 'epoch', 'object', 'iso' or 'string') you can add fake timestamps to the data. With nDataSets and nDataPoints you can define the size of the generated data. The default is 1 and 100.

Generating simple numeric data

Random address data

With the function randomAddressData you can generate addresses. You can specify the number of addresses with entries: and choose between german and US-american address types with locale: DE. The default is 10 entries and german addresses.

Generating address data

Random person data

With the function randomPersonData you can generate data about imaginary people. You can specify the number of persons with entries: and choose between german and US-american person data types with locale: DE. The default is 10 entries and german person data.

Generating person data

Random chat data

Using randomChatData you can generate data of a simulated chat. Insert the length of the conversation in the input box. The default is 10.

Generating a chat

Random point in circle

With the function randomPointInCircle you can generate one point of positional data in a circle around a specified latitude and longitude. The first input takes a number and specifies the radius of the circle in meters (default is 5000) and the second input takes the latitude and longitude coordinates, the default of which is

lat: 53.5511 lng: 9.9937

Generating a coordinate point inside a circle around a specified point

Long execution

Using longExecution, you can simulate a delay in function execution. Use this to test how your workflow will behave with different function execution times. You can specify the delay in milliseconds in the input field.
