Prototype of a JUnit Platform Test Engine for executing ScalaCheck property-based tests on the JVM.
In order to use the engine it has to be published to the local Maven repository:
./gradlew pTML
This will publish the engine unter the GAV coordinates org.scalacheck:scalacheck-engine:0.1.
In the demo/gradle folder run ./gradlew test.
This will execute com.example.StringSpecification using the built-in test task and result in den following build log:
> Task :test FAILED
String > String.concatenate FAILED
org.opentest4j.AssertionFailedError at PropertyTestDescriptor.scala:33
3 tests completed, 1 failed
A test report will be written to demo/gradle/build/reports/tests/test/index.html and a build scan will be created containing the succeeding and failing tests.
In the demo/maven folder run ./mvnw clean test.
This will execute com.example.StringSpecification using Apache Maven Surefire and result in den following build log:
