Multiple APIs

Jar's can be found here: https://bintray.com/robstoll/tutteli-jars/atrium/0.4.0
API Maturity: Almost Stable
Implementation Maturity: Development

I provide more or less a stable API for users of Atrium. Only the ReporterBuilder, which you use only to build your own assertion verb might slightly change its API (so migrating will be just a few lines in one file). There won't be any changes in the API of the assertion functions/builders.
However, I do not provide yet a stable API for the core of Atrium -- this might affect you if you write your own assertion functions as well as when you provide your own implementation of the core of Atrium.

Included in this release:

Functions to create single assertions and assertion groups.

assertion functions and builders

• assertion for nullable types
• assertions about thrown exceptions
• feature assertions for properties and return values of methods
• assertion builders for Iterable<T>
• and other assertion functions and assertion builders

Components

• Translator including a PropertiesBasedTranslationSupplier
• OnlyFailureReporting
• TextSameLineAssertionFormatter
• DetailedObjectFormatter
• ArgumentFormatter

Improvements compared to 0.3.0

• splitting of API and implementation; which enables to define multiple APIs
  • atrium-cc-en_UK-robstoll
  • atrium-cc-de_CH-robstoll
• feature assertion builders for collection/iterable
• introduction of explanatory assertion groups
• fixes for IAssertionPlantCheckingLazily -> simplified, introduce ReportingPlant as a replacement
• improved README, better explained examples

Not included in this release yet

• overload for Iterable<T> contains assertions which support identification lambdas for nullable types.

i18n for atrium

API Maturity: Almost Stable
Implementation Maturity: Development
(I provide a more or less a stable API for users of Atrium but not yet for implementers of atrium)

Included in this release:

assertion functions

• lazily and immediately evaluated assertions
• assertion for nullable types
• assertions about thrown exceptions
• feature assertions for properties and return values of methods
• and a minimal set of assertion functions

Components

• Translator including a PropertiesBasedTranslationSupplier
• OnlyFailureReporting
• SameLineAssertionFormatter
• DetailedObjectFormatter
• ArgumentFormatter

Improvements compared to 0.2.0

• i18n support for assertions and assertion verbs
• feature assertion for methods (0.2.0 had only feature assertions for properties)
• a few more assertion functions
• improved formatting in DetailObjectFormatter (boolean, enums, and KClass are treated specially)
• further improved Code-Documentation incl. a better readable layout (see KDoc)

Not included in this release yet

• basic assertion functions for collections (containsOnly, contains, containsNot, containsInOrder etc.)

Atrium's first Dev Release

Jar's can be found here: https://bintray.com/robstoll/tutteli-jars/atrium/0.2.0
Maturity: Development

Included in this release:

• lazily and immediately evaluated assertions
• assertion for nullable types
• assertions about thrown exceptions
• feature assertions for properties (functions should follow with Kotlin 1.1.2 assuming they fixed the reported bug)
• generich check for properties (functions should follow with Kotlin 1.1.2 assuming they fixed the reported bug)
• OnlyFailureReporting
• SameLineAssertionFormatter
• DetailedObjectFormatter
• and a minimal set of assertion functions

Improvements compared to 0.1.0

• cleaner code design (separation of creation, checking and reporting)
• improved Code-Documentation (KDoc available on gh-pages)
• Proper README
• Separation of API and implementation (atrium-impl-robstoll could be exchanged by another implementation)
• Spec for atrium in form of tests which can be reused by other implementation

Not included in this release yet:

• basic assertion functions for collections (containsOnly, contains, containsNot, containsInOrder etc.)
• support for multi-language assertions

Minimal Version

A minimal version of assertK including:

• assertion verb "assert"
• lazy and immediate assertions
• assertion for nullable types
• feature assertions for properties (functions will follow)
• except{} for Throwable
• OnlyFailureReporting
• SameLineAssertionMessageFormatter
• and a minimal set of assertion functions

Not included in this release yet:

• a not operator
• assertion functions for collections
• assertion functions in form of operators
