Build Status      Coverage Status      Get automatic notifications about new "fabricator" versions

Fabricator is a minimalist generator of random strings, numbers, etc. Whether you need to bootstrap your database, create good-looking XML documents, fill-in your persistence to stress test it, or anonymize data taken from a production service. It's written on scala but fully backward compatible with Java.
Fabricator is heavily inspired by Python Faker, Perl's Data::Faker, Java Faker.
Code can be found on Github

How to install :

For maven projects you need to add next dependency in your pom.xml file :

<dependency>  
  <groupId>com.github.azakordonets</groupId>
  <artifactId>fabricator_2.10</artifactId>
  <version>1.0.5</version>
</dependency>  

In case you want to use it in your scala project, then just add this lines to your build.sbt file :

resolvers += "Fabricator" at "http://dl.bintray.com/biercoff/Fabricator"

libraryDependencies += "com.github.azakordonets" % "fabricator_2.10" % "1.0.4",  

Usage

Fabricator consist of 9 specific modules :

  • Alphanumeric - generates random numbers and strings:
  • Calendar - generates random time and date:
  • Contact - generates contact and person details information :
  • File - generates random csv files
  • Finance - generates random credit cards, bsn numbers
  • Internet - generates random url's, domains, e-mails, ip's, mac addresses, color codes, social networks id's
  • Location - generates random coordinates, geohash
  • Mobile - generates random mobile platforms push tokens or id's
  • Words - generates random words, sentences and even blocks of text

To start using it you need to import fabricator.* and then make a call to appropriate module.

Let's look closer what each module can build :

Alphanumeric

This module allows you to generate any random number or string. As for strings, you can generate either fully random string,
or you can generate string basing on a pattern.

val alpha = fabricator.alphaNumeric() // initialize alpha numeric module

alpha.numerify("###ABC") // 981ABC

alpha.letterify("???123") // LsQ123

alpha.botify("???###") // AbC329

alpha.getInteger // random integer in 0 to 1000 range

alpha.getInteger(100) // random integer in 0 to 100 range

alpha.getInteger(200, 300) // random integer in 200 to 300 range

alpha.getIntegerRangeAsScalaList(1,10,1) // will return  
                                         // scala List[1,2,3,4,5,6,7,8,9,10]

alpha.getIntegerRangeAsJavaList(1,10,1) // will return  
                                        // List<Object>[1,2,3,4,5,6,7,8,9,10] . 
                                        // Each element need to be casted to Integer

alpha.hash // d750c843c83a3a980082361e72aa41ac48975eab

alpha.guid // ed7592b7-11e4-5f7f-b83f-488733c8bc56  

Besides integer numbers it can generate double, float, gausian, string

Calendar

This module allows you to generate random time or time.

val calendar = fabricator.calendar() // initialize calendar module

calendar.time12h // 03:15

calendar.time24h // 15:15

calendar.month(asNumber = false) // December

calendar.month(asNumber = true) // 12

calendar.date.asString // 10-02-2014

calendar.date.asString(DateFormat.dd_MMM_yyyy_SEMICOLON) // 10:DEC:2014

calendar.date.asDate // random Date object

calendar.date.inYear(2014).inDay(10).inMinute(10).asString // random date  
//in 2014 year,that happened in 10th day of random month 
//in 10th minute of random hour

calendar.relativeDate.years(2).weeks(1).seconds(-20).asDate  
// get relative date that is 2 years and 1 weeks in the future and 20 seconds
//behind (since current time)

calendar.relativeDate(DateTime.now().plusDays(1)).tomorrow().asString  
// 2 days since now as a string with default formatting

calendar.relativeDate(DateTimeZone.UTC).tomorrow().asString(DateFormat.dd_MM_yy)  
// tomorrows date in UTC time zone with custom formatting

calendar.datesRange  
        .startYear(2010)
        .startMonth(1)
        .startDay(1)
        .stepEvery(1, DateRangeType.DAYS)
        .endYear(2011)
        .endMonth(1)
        .endDay(1)
        .asList // list of dates between 2010-1-1 and 2011-1-1 with
// a step of 1 day between each date 

Contact

This module allows you to generate random person data

val contact = fabricator.contact()

contact.fullName // Betty Corwin

contact.birthday(25) // 26.12.1989 (current year - 25 with default format dd.MM.yyyy)

contact.bsn // 730550370

contact.eMail // Rebecca_Kohler506@yahoo.com

contact.phoneNumber // (792)273-4251 x012

contact.postCode //  44274-6580

contact.state // Alaska

contact.height(true) // 188 cm

contact.height(false) // 1.88 m

contact.weight // 108 kg

contact.bloodType // A-

contact.occupation // Craft Artist

contact.religion // sikhism

contact.zodiac // Taurus

File

This module allows you to generate random images and csv files.
For images you can specify width and height ( no more then 2560 px) and as a result you will get an image
that has text of it's dimensions on it. It's easy as :

val file = fabricator.file() // initialize file module

file.image(200,300, "drawing.png")  
// will create a 200x300 image in the root of the project

For csv there are 2 ways of generating files.
First one is by using specific codes that correspond to the methods that are available withing the lib. Here's the full list of supported codes :

  • integer
  • double
  • hash
  • guid
  • time
  • date
  • name
  • first_name
  • last_name
  • birthday
  • email
  • phone
  • address
  • postcode
  • bsn
  • height
  • weight
  • occupation
  • visa
  • master
  • iban
  • bic
  • url
  • ip
  • macaddress
  • uuid
  • color
  • twitter
  • hashtag
  • facebook
  • google_analytics
  • altitude
  • depth
  • latitude
  • longitude
  • coordinates
  • geohash
  • apple_token
  • android
  • windows7Token
  • windows8Token
  • word
  • sentence

To create csv file using this codes you need to do next :

val file = fabricator.file() // initialize file module

val codes = Array("first_name", "last_name",  
"birthday", "email", "phone", "address", "bsn", "weight", "height")

file.csvFromCodes(codes, 10, csvFilePath)  
// this will create a csv file with 10 rows, each of 
//it has set of data generated by 
//fabricator methods and stored in csvFilePath

In case you miss some code for your need, or you want to put your data into csv file generator, you can specify them in Set and then ask fabricator
to generate csv file with this data :

val file = fabricator.file() // initialize file module

val values = Seq(alpha.getInteger, alpha.getDouble, calendar.ampm, null)

file.csv(values, 10, csvFilePath)  
// csv file with 10 lines of data from Set will be generated //in csvFilePath

Finance

This module allows you to generate random finance data

val finance = fabricator.finance() // initialize finance module

finance.iban // GB91ROYC80901351879409

finance.bic // CLSBUS33XXX

        .params(mutable.Map[String, Any]("id"->100,
                                         "name" -> "John Lennon",
                                         "coordinates" -> 30.03))
                                         .toString() 
// https://google.com/getNewId?id=100&name=John+Lennon&coordinates=30.03

internet.urlBuilder.host("test.com").params(mutable.Map("q"->"test 123"))  
                                    .encodeAs(Charset.forName("UTF-8"))
                                    .toString()
