Mar 5, 2019 When assertions fail, they raise an AssertionErrorException .

An assertion failure will not throw an appropriate exception. If perform method throws exception of expected type, that is IllegalArgumentException here, then first catch block would be executed where we also can assert extra stuff. If perform method throws exception of some other type then second catch would be executed where Assert.fail("Unexpected Exception"); would fail the test. IllegalArgumentException extends RuntimeException and it is unchecked exception. So we don’t need to catch it. We have to fix the code to avoid this exception.

In other words, it is common to use an assert statement that always produces a false value, yet in a location where execution of the assert statement should not be possible. Testing assert statements ÓDavid Gries, 2018 A method with a precondition may have assert statements to test that precondition, as in these examples: If foo and bar refer to the same object, an IllegalArgumentException is and the message will be "foo == bar." Ensuring a String is not empty Assert.notEmptyString ( "fooStr is empty", fooStr ); There are two types of IllegalArgumentException that are thrown while starting the spring boot application. java.lang.IllegalArgumentException: Sources must not be empty java.lang.IllegalArgumentException: Args must not be empty.

public class Assert { public static void notFalse(boolean flag, String message) { if (!flag) { System.out.println(message); throw new IllegalArgumentException(); }

You're trying to instantiate a DinetteStore with illegal parameters, so you want: @Test (expected = IllegalArgumentException.class) public void testIllegalArgumentChair () { int tableInventory = -1; int leafInventory = -1; int chairInventory = -1; DinetteStore creationWillFail = new DinetteStore (tableInventory, leafInventory, chairInventory); }

This also means that if we pass Exception.class as the expected exception type, any exception thrown from the code block will make the assertion succeed since Exception is the super-type for all exceptions.

If one is not raised, then the assertion will fail. If one does occur, then the assertion will pass and the exception is caught. Do not use assertions to check the parameters of a public method. An assert is inappropriate because the method guarantees that it will always enforce the argument checks. It must check its arguments whether or not assertions are enabled. Further, the assert construct does not throw an exception of the specified type.

Throwable throwableWithMessage = new IllegalArgumentException("wrong Deprecated. Asserts that an argument is legal. If the given boolean is not true , an IllegalArgumentException is thrown. You are not instantiating the class that will throw the exception . And the syntax you have is not correct, it should be something like: @Test public class Assert { public static void notFalse(boolean flag, String message) { if (!flag) { System.out.println(message); throw new IllegalArgumentException(); } as seen in Groovy.
