I'm trying to work on a homework assignment. We're given a bunch of files, and the first step in the instructions says that I need to run one of the Java files that we're given, which acts as a testing file.
Here is the file,
import org.junit.runner.JUnitCore;
import org.junit.runner.Result;
import org.junit.runner.notification.Failure;
public class ListBoundedIntSetTestSuiteRunner {
public static void main (final String[] args) {
final Result result =
JUnitCore.runClasses(ListBoundedIntSetTestSuite.class);
for (final Failure failure : result.getFailures()) {
System.out.println(failure.toString());
}
if (result.wasSuccessful()) {
System.out.println("Congratulations: all tests passed!");
}
final int runs = result.getRunCount();
final int failures = result.getFailureCount();
final int ignores = result.getIgnoreCount();
final int successes = runs - failures;
System.out.printf("Tests run: %d%n", runs);
if (ignores > 0) {
System.out.printf("Tests ignored: %d%n", ignores);
}
System.out.printf("Tests passed: %d%n", successes);
if (failures > 0) {
System.out.printf("Tests failed: %d%n", failures);
}
}
}
The instructions literally say that I just have to open this in Eclipse and click run and it should work. I have seen this work on a friend's computer as well. I have not changed any files or done anything at all.
When I try to run this file, I get the error "Selection does not contain a main type".
I have cleaned the workspace, uninstalled and reinstalled Eclipse, uninstalled and reinstalled Java but nothing seems to work.
