+
+A tool to generate well-defined, but essentially random, input following the
+idea of constrained non-determinism.
+
+== Getting started
+
+Include the following dependency in your `build.gradle.kts` file:
+
+[source,kotlin]
+._build.gradle.kts_
+----
+testImplementation("com.appmattus.fixture:fixture:<latest-version>")
+----
+
+Simply create a fixture and invoke it with the type to be generated:
+
+[source,kotlin]
+----
+val fixture = kotlinFixture()
+
+// Generate a list of strings
+val aListOfStrings = fixture<List<String>>()
+
+// Nulls are supported
+val sometimesNull = fixture<Int?>()
+
+// Create instances of classes
+// Optional parameters will be randomly used or overridden
+data class ADataClass(val value: String = "default")
+val aClass = fixture<ADataClass>()
+
+// Abstract classes will pick a sub-class at random
+// This could be a Byte, Double, Long, Float, Int or Short
+val anyNumber = fixture<Number>()
+
+// Pick randomly from a list
+val randomStringFromTheList = fixture(listOf("Cat", "Dog", "Horse"))
+val anotherRandomIntFromAList = fixture(1..5)
+----
+
+You can also generate an infinite sequence of a type, which you can then
+filter:
+
+[source,kotlin]
+----
+val fixture = kotlinFixture()
+
+val intSequence = fixture.asSequence<Int>()
+
+// Standard Kotlin sequence functions can then be applied before using
+// the sequence through an iterator for access to the next() function.
+
+// For example, you can filter values
+val oddIterator = intSequence.filter { it.absoluteValue.rem(2) == 1 }.iterator()
+val oddNumber = oddIterator.next()
+val anotherOddNumber = oddIterator.next()
+
+// Or, ensure it returns only distinct values
+enum class XYZ { X, Y, Z }
+val enumIterator = fixture.asSequence<XYZ>().distinct().iterator()
+val aDistinctValue = enumIterator.next()
+val anotherDistinctValue = enumIterator.next()
+----
+
+[WARNING]
+====
+The sequence can hang indefinitely if the applied operators prevent the generation of new values. For example:
+
+* `distinct` will hang if we exhaust all available values. A good practice is to add a `take(count)` which will throw a `NoSuchElementException` if we try to generate more values.
+* `filter` that can never be fulfilled e.g. `filter { false }`
+====
+
+== Configuration options
+
+Everything can be customised, see link:fixture/configuration-options.adoc[configuration options] for more details.
+
+== Kotest integration: property based testing
+
+The library provides {link-appmattus} powered property based testing for https://github.com/kotest/kotest/[Kotest].
+
+See link:fixture-kotest/README.adoc[Kotest integration] for more details.
+
+== Java Faker integration: pretty data
+
+Generate values with a closer match to real data using http://dius.github.io/java-faker/[Java Faker].
+
+See link:fixture-javafaker/README.adoc[Java Faker integration] for more details.
+
+== Generex integration: regex to random string
+
+To generate a random string from a Regex, look no further than the Generex integration.
+
+See link:fixture-generex/README.adoc[Generex integration] for more details.
