Simple Type Generators

Simple Type Generators in DATAMIMIC are essential for generating fundamental data types like strings, numbers, and other basic data types. These generators are highly configurable, allowing you to specify patterns, ranges, and formats to produce realistic test data.

AcademicTitleGenerator

Generates academic titles.

Properties:

  • dataset: Either a region name or the two-letter-ISO-code of a country. Supported dataset: US, DE, FR, CN, IT
  • quota: The quota of generated title. (default: 0.5)

1
<key name="academic_title" generator="AcademicTitleGenerator"/>
or 
1
<key name="academic_title" generator="AcademicTitleGenerator(dataset='US', quota='1')"/>

Sample Output:

<setup>
    <!-- Generate a dataset with various simple types -->
        <generate name="simple_types_dataset" count="100" target="ConsoleExporter">
        <key name="academic_title" generator="AcademicTitleGenerator"/>
        <key name="is_active" generator="BooleanGenerator"/>
        <key name="cnpj" generator="CNPJGenerator"/>
        <key name="cpf" generator="CPFGenerator"/>
        <key name="company_name" generator="CompanyNameGenerator"/>
        <key name="created_at" generator="DateTimeGenerator(min='2010-08-01', max='2020-08-31', input_format='%Y-%m-%d')"/>
        <key name="domain" generator="DomainGenerator"/>
        <key name="ean" generator="EANGenerator"/>
        <key name="email" generator="EmailAddressGenerator"/>
        <key name="last_name" generator="FamilyNameGenerator"/>
        <key name="first_name" generator="GivenNameGenerator"/>
        <key name="incremental_id" generator="IncrementGenerator"/>
        <key name="phone_number" generator="PhoneNumberGenerator"/>
        <key name="sector" generator="SectorGenerator"/>
        <key name="ssn" generator="SSNGenerator"/>
        <key name="random_string" generator="StringGenerator(max_len=20)"/>
        <key name="uuid" generator="UUIDGenerator"/>
    </generate>
</setup>

In this example:

  • <AcademicTitleGenerator> generates academic titles.
  • <BooleanGenerator> generates boolean values.
  • <CNPJGenerator> generates Brazilian company identification numbers.
  • <CPFGenerator> generates Brazilian individual taxpayer registry identification.
  • <CompanyNameGenerator> generates company names.
  • <DateTimeGenerator> generates date and time values within a specified range.
  • <DomainGenerator> generates domain names.
  • <EANGenerator> generates International Article Numbers.
  • <EmailAddressGenerator> generates email addresses.
  • <FamilyNameGenerator> generates family names.
  • <GivenNameGenerator> generates given names.
  • <IncrementGenerator> generates incrementing IDs.
  • <IntegerGenerator> generates integer values within a specified range.
  • <PhoneNumberGenerator> generates phone numbers.
  • <SectorGenerator> generates business sectors.
  • <SSNGenerator> generates Social Security Numbers.
  • <StringGenerator> generates random strings based on specified characteristics.
  • <UUIDGenerator> generates universally unique identifiers.

By utilizing these simple type generators, you can create diverse and realistic datasets for comprehensive testing scenarios in DATAMIMIC.
