What is a good way in maven/surefire to clean up after unit tests, whether they pass or not?

Question

We have some unit tests that unfortunately create memory-mapped NIO files that cannot be deleted by the process that created them (some windows issue).

Regardless, I would like to run some sort of clean up after these tests, whether they passed or not. I was going to run a small ant script at the prepare-package phase, but if any test fails, surefire exits immediately.

Apart from going to the failsafe plugin which has a post-test phase, is there any clever way I can run my cleanup regardless of pass or fail?

I suspect not - I've gone through all the surefire config options...

edit: memory-mapped nio files cannot be deleted in the same process, even by deleteOnExit.

if you don't care that the files are lying around, you could delete them **before** the tests, e.g. in the `process-test-resources` build phase — Absurd-Mind, Aug 17 '12 at 00:17
Are you *sure* they can't be deleted? Have you tried `java.io.File.deleteOnExit()`? — artbristol, Aug 17 '12 at 07:59

You should bound the thing you want to do into the post-integration-test lifecycle phase which is running afterwards the integration-test phase which is handled by the maven-failsafe-plugin. It might work if you configure the maven-clean-plugin to do so.

if surefire fails on a test, it doesn't seem to fire off any more phases. It just forces maven to exit. – marathon Aug 24 '12 at 03:41

Of course, cause failing tests is an indication that's something wrong which needs to be fixed first before continuing. You can use mvn -Dmaven.test.failure.ignore=true (but i don't recommend that). – khmarbaise Aug 24 '12 at 07:22

@marathon Failsafe is designed so that even if the tests fail, the `post-integration-test` phase still runs and does any cleanup – artbristol Aug 24 '12 at 08:13

@artbristol that's supposed to be the case, but I haven't seen a good sample pom file that demonstrates it along with how everything needs to be configured. I'm having a somewhat similar problem as marathon and I'm sure it's a configuration problem, but I can't figure out what I'm doing wrong. But marathon wants to try to do it without failsafe, anyway. – Rebeccah May 17 '17 at 22:49

I would make sure the files are created in either target/ or the OS's temporary directory (using System.getProperty("java.io.tmpdir"). Then they will be cleaned up automatically when you run mvn clean, or eventually by the OS.

Add following dependancy in pom and remove existing from your POM

        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>

                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-surefire-plugin</artifactId>
                    <version>2.19.1</version>
                </plugin>
            </plugins>
        </build>
