Is there a Java continuous testing plugin for Maven?

Question

I'm looking for a plugin that would run in a console continuously to scan a Maven project's test sources directory, and when it detects a change kicks off a test cycle. Something analogous to mvn scala:cc or the Scala Build Tool, but for Java. Can anyone point me towards one?

This might be obvious but, you are aware that there are continuous integration servers with good support for maven, right? e.g. Jenkins-CI – Cachet

Yeah, I do. I am looking for something simple out of the box to run in a console alongside a text editor when I don't have access to a full-blown IDE. – Bricker

Ok, all clear. You want eclipse's autobuild functionality minus eclipse :) – Cachet

That's pretty much it :) – Bricker

but jenkins offer a consloe command interface to manipulate it – Disused

Answer 1

I have personally used sbt even for a java only project just for continuous test feature.

I added a sbt build file to a maven based project and use sbt when developing, but use maven when building the final package, starting embedded jetty etc and this has worked out quite well.

That's certainly one way to do it, but I'm looking for something that wouldn't require me to introduce sbt. – Bricker

It's quite possible that there isn't actually a Maven continuous compilation plugin, so this is the best answer that I received. Thanks! – Bricker

Answer 2

I've just discovered that the scala-maven-plugin supports both continuous compilation & testing, as well as cross-compilation (Java + Scala). So it's possible to use it over a pure Java build and get all the continuous build goodness.

You're a genius, sir! :D It worked. see also https://mcmap.net/q/716188/-is-there-a-scala-unit-test-tool-that-integrates-well-with-maven – Urnfield

Answer 3

Recently, I have had a need for a solution to this. Having been learning scala and finding about the goodness of sbt ~test, I want to apply it to Java projects that do not have continuous test.

Using the scala-maven-plugin that you mentioned, I have created a github seed that will run Java Junit tests everytime I save a Java source or a Java test.

Check it out: https://github.com/ailveen/maven-scala-java-continuous-test

The project is very simple right now (contains only Java files because that is my current need) but in the future I hope to add scala test (or specs2 or scalacheck) so it works with mixed java and scala files.

Hope you find it useful.

It is not exactly for Maven, but JUnit Max does continuous testing and if you're on Eclipse it might be the tool you would like to check out
