Run JUnit test from the command line

JUnit tests can be run easily from within your IDE. Every remotely up to date IDE has some built-in view that gives nice visual feedback, usually red or green indicators.
But of course it is also possible to invoke your tests from the command line. A simple example:
import org.junit.runner.JUnitCore;
public class MyClass {
public static void main(String[] args) {
JUnitCore.main(MyJUnitTest.class.getName());
}
}
A very nice article on JUnit testing by Lars Vogel can be found at http://www.vogella.com/articles/JUnit/article.html. He suggests iterating through the failures of a Result class to run the tests via code, which works fine, too:
import org.junit.runner.JUnitCore;
import org.junit.runner.Result;
import org.junit.runner.notification.Failure;
public class MyClass {
public static void main(String[] args) {
Result result = JUnitCore.runClasses(MyJUnitTest.class);
for (Failure failure : result.getFailures()) {
System.out.println(failure.toString());
}
}
}
