Test Data Guide

Random Data Generator

A full-featured random data generator is shipped with T.apex. We can use this random data generator to generate test data.

In test code, we can do this:

String s = (String)T.create('String');

And this will generate a random string for us.

Also we can use below, which is equivalent to the above.

String s = (String)Random.anyString.run();

Random is just the random data generator in T.apex. Note that T can only be used in test codes, while Randomis just a utility class and can be used anywhere outside test codes.

Therefore, if we want to generate random data outside test codes, please use the latter form.

Generator Options

We can actually pass in options to fine tune how we would like the random data to be generated.

String s = (String)T.create('String', new Map{ ... });

Or

String s = (String)Random.anyString.run(new Map{ ... });

are the equivalent. The details of the options rely on the random data we want to generate.

Random Object

We can create a random Object like this:

Random.anyObject.run(new Map{
    'type' => 'String',
    'config' => new Map{ 'min' => 5 }
})

Here are the options:

Available types are:

For any other types, T.apex will try to find the Type and instantiate it.

Random Boolean

We can create a random Boolean like this:

Random.anyBoolean.run(new Map{
    'likelihood' => 60
})

Here are the options:

Random Integer

We can create a random Integer like this:

Random.anyInteger.run(new Map{
    'min' => 5,
    'max' => 20
})

Here are the options:

Random Long

We can create a random Long like this:

Random.anyLong.run(new Map{
    'min' => 5,
    'max' => 20
})

Here are the options:

Random Double

We can create a random Double like this:

Random.anyDouble.run(new Map{
    'min' => 5,
    'max' => 20
})

Here are the options:

Random Decimal

We can create a random Decimal like this:

Random.anyDecimal.run(new Map{
    'min' => 5,
    'max' => 20
})

Here are the options:

Random Char

We can create a random Char like this:

Random.anyChar.run(new Map{
    'alpha' => true
})

Here are the options:

Random String

We can create a random String like this:

Random.anyList.run(new Map{
    'type' => 'String',
    'min' => 5
})

Here are the options:

Random List

We can create a random List
