Ich kann eine sehr einfache Testklasse nicht mit dem Powermock-Testlauf ausführen. Es verursacht einen ExceptionInInitializerError. Es scheint ein Problem mit den Abhängigkeiten vom Klassenpfad zu sein, jedoch habe ich einige Varianten der Abhängigkeitsversionen ausprobiert, aber alle verursachen den gleichen Fehler. Wie kann ich diesen einfachen Test bestehen, wenn ich den Powermock Test Runner verwende?PowerMockRunner verursacht ExceptionInInitializerError, wenn Trivialtest ausgeführt wird
Der Testcode:
package net.solasistim.hello;
import org.junit.Test;
import org.junit.Assert;
import org.junit.runner.RunWith;
import org.powermock.modules.junit4.PowerMockRunner;
@RunWith(PowerMockRunner.class)
public class HelloTest {
@Test
public void testMain() {
Assert.assertTrue(true);
}
}
