开源软件名称(OpenSource Name):appmattus/kotlinfixture开源软件地址(OpenSource Url):https://github.com/appmattus/kotlinfixture开源编程语言(OpenSource Language):Kotlin 99.4%开源软件介绍(OpenSource Introduction):KotlinFixtureA tool to generate well-defined, but essentially random, input following the idea of constrained non-determinism. Getting startedInclude the following dependency in your build.gradle.kts
testImplementation("com.appmattus.fixture:fixture:<latest-version>") Simply create a fixture and invoke it with the type to be generated: 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: 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()
Configuration optionsEverything can be customised, see configuration options for more details. Advanced engine customisation is also possible if the above options are not enough. Kotest integration: property based testingThe library provides KotlinFixture powered property based testing for Kotest. See Kotest integration for more details. Java Faker integration: pretty dataGenerate values with a closer match to real data using Java Faker. See Java Faker integration for more details. Generex integration: regex to random stringTo generate a random string from a regular expression, look no further than the Generex integration. See Generex integration for more details.
