Create a java class file named in C:\>JUNIT_WORKSPACE.. import org.junit.Test; import static org.junit.Assert.*; public class TestAssertions { @Test public void testAssertions() { //test data String str1 = new String ("abc"); String str2 = new String ("abc"); String str3 = null; String str4 = "abc"; String str5 Assert. JUnit Jupiter附带了许多JUnit 4拥有的断言方法,并添加了一些可以很好地用于Java 8 lambdas的断言方法。 所有JUnit木星断言都是 org.junit.jupiter.api.Assertions 中的静态方法断言类。 The following examples show how to use org.junit.Assert#assertThat() .These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. We could do this by removing the reference to the JUnit Assert class, and getting IntelliJ IDEA to static import the Hamcrest MatcherAssert.assertThat. We can use optimise imports to remove the unnecessary JUnit 4 Assert import.

The assertThrows () method asserts that execution of the supplied executable block or lambda expression which throws an exception of the expectedType. public static T assertThrows (Class expectedType, Executable executable) You can use assertThrows (), But with assertThrows your assertion will pass even if the thrown exception is of child type. This is because, JUnit 5 checks exception type by calling Class.isIntance (..), Class.isInstance (..) will return true even if the exception thrown is of the child types. The workaround for this is to assert on Class: The Assert.Throws method is pretty much in a class by itself. Rather than comparing values, it attempts to invoke a code snippet, represented as a delegate, in order to verify that it throws a particular exception. It's also in a class by itself in that it returns an Exception, rather than void, if the Assert is successful. If the method SomethingThatThrowsAnException () from the above throws an exception the assertion passes, if it does not throw an exception, the assertion will fail and thereby the test fails.
