### Question:
SecurityChecks { public static ISecurityCheck or(ISecurityCheck[] checks) { return new OrSecurityCheck(checks); }  static ISecurityCheck and(ISecurityCheck[] checks); static ISecurityCheck and(ISecurityCheck check1, ISecurityCheck check2); static ISecurityCheck or(ISecurityCheck[] checks); static ISecurityCheck or(ISecurityCheck check1, ISecurityCheck check2);  }### Answer:
@Test public void testOr() { runCheck(SecurityChecks.or(null, null), true, true); runCheck(SecurityChecks.or(null), true, true); runCheck(SecurityChecks.or(new BogusCheck(true), null), true, true); runCheck(SecurityChecks.or(new ISecurityCheck[] { new BogusCheck(true) }), true, true); runCheck(SecurityChecks.or(new ISecurityCheck[] { new BogusCheck(true), null }), true, true); runCheck( SecurityChecks.or(new ISecurityCheck[] { new BogusCheck(true), new BogusCheck(true, false) }), true, true); runCheck( SecurityChecks.or(new ISecurityCheck[] { new BogusCheck(true), new BogusCheck(false, true) }), true, true); runCheck( SecurityChecks.or(new ISecurityCheck[] { new BogusCheck(true), null, new BogusCheck(true), new BogusCheck(false) }), true, true); runCheck(SecurityChecks.or(new ISecurityCheck[] { new BogusCheck(false) }), false, false); runCheck(SecurityChecks.or(new BogusCheck(false), new BogusCheck(false)), false, false); }
