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. The run api in the SpringApplication is used to start a spring boot application. Here we'll be covering Java assertion statements which allow us to set pre conditions for our functions and ensure that our programs are meeting the constrai 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: Example@Test(expected=IllegalArgumentException.class) By using "expected" parameter, you can specify the exception name our test may throw. In above example, you are using " IllegalArgumentException" which will be thrown by the test if a developer uses an argument which is not permitted.

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 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.

See the NOTICE file distributed java.lang.IllegalArgumentException: Sources must not be empty #161, SpringApplication : Application startup failed java.lang.IllegalArgumentException: Sources must not be empty at org.springframework.util.Assert I got stuck with an "java.lang.IllegalArgumentException: the name must not be empty: null" Exception on Google Drive Android app. Coding Bootcamp: Unit Testing with JUnit Learning objectives. What is Unit Testing; What is considered a Unit in Java; How the JUnit framework provides Unit Testing support in Java; Motivating example.

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)

Summary Clarify Exception IllegalArgumentException: [Assertion failed] - this argument is required; it must not be null Actual Behavior java.lang.IllegalArgumentException: [Assertion failed] - this argument is required; it must not be nu The IllegalArgumentException is intended to be used anytime a method is called with any argument(s) that is improper, for whatever reason.
