@Test public void testDump() throws Throwable { PrintStream p = new PrintStream(new ByteArrayOutputStream()); new LogEvent("testLogEventTag").dump(p, "\r\n"); assertTrue(true, "Test completed without Exception"); }
@Test public void testDump3() throws Throwable { new LogEvent(new ThreadPool(0, 0), "testString", null).dump(new PrintStream(new ByteArrayOutputStream(), true), "a42"); assertEquals("a42", "a42", "\"a42\""); }
@Test public void testDumpThrowsNullPointerException() throws Throwable { try { new LogEvent("testLogEventTag").dump(null, "testLogEventIndent"); fail("Expected NullPointerException to be thrown"); } catch (NullPointerException ex) { if (isJavaVersionAtMost(JAVA_14)) { assertNull(ex.getMessage(), "ex.getMessage()"); } else { assertEquals("Cannot invoke \"java.io.PrintStream.println(String)\" because \"p\" is null", ex.getMessage(), "ex.getMessage()"); } } }
