Assertion utility class that assists in validating arguments. Useful for Assert a boolean expression, throwing IllegalArgumentException if the test result is false .

Further, the assert construct does not throw an exception of the specified type. If the expected exception is thrown, assertThrows returns the exception, which enables us to also assert on the message. Furthermore, it's important to note that this assertion is satisfied when the enclosed code throws an exception of type NullPointerException or any of its derived types. Since all seven assert statements of Junit4AssertionTest.java class returns true, therefore when you execute the test assert class, it will return a successful test. (see the output below) (see the output below)

Kumar V's answer of adding @AutoConfigureMockMvc(addFilters = false) is only a workaround because it disables the JwtRequestFilter, which is not good practice in this case. Since all seven assert statements of Junit4AssertionTest.java class returns true, therefore when you execute the test assert class, it will return a successful test. (see the output below) (see the output below) The IllegalArgumentException is very useful and can be used to avoid situations where the application’s code would have to deal with unchecked input data. The main use of this IllegalArgumentException is for validating the inputs coming from other users. If we want to catch the IllegalArgumentException then we can use try-catch blocks. IllegalArgumentException public IllegalArgumentException( Throwable cause) Constructs a new exception with the specified cause and a detail message of (cause==null ? null : cause.toString()) (which typically contains the class and detail message of cause ).

For example, if we are expecting IllegalArgumentException and the test throws NumberFormatException then also the test will PASS because NumberFormatException extends IllegalArgumentException class. You can use assertThrows(), But with assertThrows your assertion will pass even if the thrown exception is of child type.

Here’s an example: 2019-11-02 Mocking jwtRequestFilter causes Spring to attempt to use the mock as an actual filter. This is what is causing the exception.

Spring 对方法入参的检测借用了这个概念，其提供的 Assert 类拥有众多按规则对方法入参进行断言的方法，可以满足大部分方法入参检测的要求。这些断言方法在入参不满足要求时就会抛出 IllegalArgumentException。 Assert 类中的常用断言方法:

アサーションの失敗時に IllegalArgumentException をスローする場合は、isTrue(boolean, java.lang.String) を呼び出します。 Assert.state(entity.getId() == null, () -> "ID for entity " + entity.getName() + " must not already be initialized"); Assert a boolean expression, throwing IllegalArgumentException if the test result is false.
