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.

If an argument value is deemed invalid, an IllegalArgumentException is thrown (typically). For example: Assert.notNull(clazz, "The class must not be null"); Assert.isTrue(i > 0, "The value must be greater than zero");

* * @throws IllegalArgumentException if any param does not comply. assert宏的原型定义在中，其作用是如果它的条件返回错误，则终止程序执行，原型定义：#include void assert( int expression );assert的作用是现计算表达式 expression ，如果其值为假(即为0)，那么它先向stderr打印一条出错信息，然后通过调用#include #include #include int main( void ){FILE *f assert. 値が正しい（仕様の範囲内である）ことをチェックする構文としてassertがある。 使い所はIllegalArgumentExceptionやIllegalStateExceptionと被るが。 * Assert a boolean expression, throwing an {@code IllegalArgumentException} * if the expression evaluates to { @code false }. * @deprecated as of 4.3.7, in favor of { @link #isTrue(boolean, String) } 指定された文字列が空でないことを表明します。 指定された文字列が null または空の場合は、IllegalArgumentException をスローします。 Assert.notEmpty(name, "Name must not be empty"); パラメータ: str - 検査する文字列 message - 例外をスローする場合に使用するメッセージ 例外: JUnit Assert Class.

Another problem with using assertions for argument checking is that erroneous arguments should result in an appropriate runtime exception (such as IllegalArgumentException, IndexOutOfBoundsException, or NullPointerException). An assertion failure will not throw an appropriate exception.

If overdraft, runtime exception IllegalArgumentException is raised and balance is Object actual); fail(string message); Assert betyder ungefär att hävda, påstå. FÖRSÄKRAN (ASSERTION). EXEMPEL: PRE A BEVISA FÖLJANDE: Kop 1 while { INVB. A {kod 1} B. KOO 2 3.

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)
