Hi Andreas,
I just took a copy of `System.out` before it gets replaced inside other
listeners.
Let me share my code with you:
```
import java.io.PrintStream;
import java.time.Duration;
import java.time.Instant;
import java.util.Optional;
import java.util.concurrent.atomic.AtomicInteger;
import org.junit.platform.engine.TestExecutionResult;
import org.junit.platform.launcher.TestExecutionListener;
import org.junit.platform.launcher.TestIdentifier;
public class JUnitSummary implements TestExecutionListener {
private AtomicInteger numSkippedInTestSet = new AtomicInteger();
private AtomicInteger numAbortedInTestSet = new AtomicInteger();
private AtomicInteger numSucceededInTestSet = new AtomicInteger();
private AtomicInteger numFailedInTestSet = new AtomicInteger();
private Instant testSetStartTime;
PrintStream out = null;
public JUnitSummary() {
this.out = System.out;
}
private void resetCountsForNewTestSet() {
this.numSkippedInTestSet.set(0);
this.numAbortedInTestSet.set(0);
this.numSucceededInTestSet.set(0);
this.numFailedInTestSet.set(0);
this.testSetStartTime = Instant.now();
}
@Override
public void executionStarted(TestIdentifier testIdentifier) {
Optional<String> parentId = testIdentifier.getParentId();
if (parentId.isPresent() && parentId.get().indexOf('/') < 0) {
println("\nRunning " + testIdentifier.getLegacyReportingName());
resetCountsForNewTestSet();
}
}
@Override
public void executionSkipped(TestIdentifier testIdentifier, String reason)
{
this.numSkippedInTestSet.incrementAndGet();
}
@Override
public void executionFinished(TestIdentifier testIdentifier,
TestExecutionResult testExecutionResult) {
Optional<String> parentId = testIdentifier.getParentId();
if (parentId.isPresent() && parentId.get().indexOf('/') < 0) {
int totalTestsInClass = this.numSucceededInTestSet.get() +
this.numAbortedInTestSet.get() + this.numFailedInTestSet.get()
+ this.numSkippedInTestSet.get();
Duration duration = Duration.between(this.testSetStartTime,
Instant.now());
double numSeconds = (double) duration.toMillis() / 1_000;
String summary = String.format("Tests run: %d, Failures: %d,
Aborted: %d, Skipped: %d, Time elapsed: %f sec", totalTestsInClass,
this.numFailedInTestSet.get(),
this.numAbortedInTestSet.get(), this.numSkippedInTestSet.get(), numSeconds);
println(summary);
} else if (testIdentifier.isTest()) {
switch (testExecutionResult.getStatus()) {
case SUCCESSFUL:
this.numSucceededInTestSet.incrementAndGet();
break;
case ABORTED:
println(" Aborted: " + testIdentifier.getDisplayName());
this.numAbortedInTestSet.incrementAndGet();
break;
case FAILED:
println(" Failed: " + testIdentifier.getDisplayName());
this.numFailedInTestSet.incrementAndGet();
break;
}
}
}
private void println(String str) {
this.out.println(str);
}
}
```
And then I use it like this in ant:
```
<junitlauncher haltOnFailure="false" printSummary="true">
<testclasses>
<fileset dir="...">
<include name="**/*Test.class" />
</fileset>
<listener classname="JUnitSummary" />
<listener type="legacy-xml" sendSysOut="true" sendSysErr="true" />
<listener type="legacy-plain" sendSysOut="true" sendSysErr="true" />
</testclasses>
</junitlauncher>
```
