+# Reactive Streams TCK for Junit 5 
+
+_This module is a fork of the Reactive Streams TCK (https://github.com/reactive-streams/reactive-streams-jvm/tree/master/tck)
+ but use Junit 5 instead of TestNG. This project does not depend on Mutiny._
+
+The purpose of the *Reactive Streams Technology Compatibility Kit* (from here on referred to as: *the TCK*) is to guide
+and help Reactive Streams library implementers to validate their implementations against the rules defined in
+ [the Specification](https://github.com/reactive-streams/reactive-streams-jvm).
+
+## Structure of the TCK
+
+The TCK aims to cover all rules defined in the Specification, however for some rules outlined in the Specification it is
+not possible (or viable) to construct automated tests, thus the TCK can not claim to fully verify an implementation, however it 
+is very helpful and is able to validate the most important rules.
+
+The TCK is split up into 4 test classes which are to be extended by implementers, providing their `Publisher` / `Subscriber` 
+/ `Processor` implementations for the test harness to validate.
+
+The tests are split in the following way:
+
+* `PublisherVerification`
+* `SubscriberWhiteboxVerification`
+* `SubscriberBlackboxVerification`
+* `IdentityProcessorVerification`
+
+The sections below include examples on how these can be used and describe the various configuration options.

+<dependency>
+  <groupId>io.smallrye.reactive</groupId>
+  <artifactId>reactive-streams-junit5-tck</artifactId>
+  <version>${last mutiny release}</version>
+  <classifier>tests</classifier>
+  <type>test-jar</type>
+  <scope>test</scope>
+</dependency>
+```
+
+Please refer to the [Reactive Streams Specification](https://github.com/reactive-streams/reactive-streams-jvm) for the official,
+ and to the last Mutiny release to find the latest version. Make sure that your Reactive Streams API and TCK dependency versions match.
