Is there a way to tell whether a JUnit test is being run from Ant?

Question

I want to recognize at runtime whether my JUnit tests are being run from ant or not. The reason for this is, if it's being run from ant, I want to log information to a log file, else I just want to write to standard out.

This is a guess, but I'd image ant would be able to do this. Ant launches a JVM to run your tests. There might be a way to configure that JVM to redirect its output a different location/file. That's where I would start. Your way is kind of backwards. — Sotirios Delimanolis, Nov 18 '14 at 20:36
Did you try to configure logger properly? When start from ant use configuration with ConsoleAppender. — Dmytro, Nov 18 '14 at 20:38

Ant's built in JUnit Task has a showoutput attribute which will send any output produced from the tests to ant's logging system.

One way to accomplish this would be to include a property in the junit task in the Ant script:

<junit fork="yes">
  <jvmarg value="-Druntime.agent=ANT"/>
  ...
</junit>

Then, in your JUnit test harness inquire about the existence and/or property for that property:

String agent = System.getProperty("runtime.agent");
if ("ANT".equals(agent)) {
    // set up file logging
} else {
    // set up STDOUT logging
}
