assertEquals(s1, s2): The JUnit method compares whether two strings have the same value. In the given example, two string variables have having same values, so the assertion will pass. Modify the values of the string as mentioned below import org.junit.Test; import static org.junit.Assert....
org.junit.Assert中的assertEquals(long,long) 首先使用这个方法的前提是要导入Junit的包,这样就可以使用@Test单元测试了 idea自动导入Junit方法 在方法头上编写org.junit.Test然后根据快捷键的提示导入相关包 这样Junit就导进来啦 其次就开始使用assertEquals(long,long)方法,这个方法有很多种,这里就介绍这一种 导入...
In JUnit 4, we can test whether a method throws an exception by using the expected attribute of the @Test annotation. We can use the Assertions.assertThrows() to test the same thing in JUnit 5.In this tutorial, we will learn how to check whether an exception occurs using JUnit....
JUnit assertEquals is one of the methods in the JUnit Library to verify the equality of two objects. For example, one of the objects may be the program output, and the other may be externally supplied to the code. The intention of the verification is to ensure that the program works as ...
Above method must be used if arrays have the same length, for each valid value fori, you can check it as given below: assertEquals(expected[i],actual[i]) assertArrayEquals(expected[i],actual[i]) RELATED ARTICLES JUnit Tutorial for Beginners: Learn in 3 Days ...

differences between 2 JUnit Assert classes The old method (of Junit 3) was to mark the test-classes by extending junit.framework.TestCase. That inherited junit.framework.Assert itself and your test-class gained the ability to call the assert-methods this way. ...
IntestExpectedExceptionWithParentType, we are executing the same code but this time we are exceptingIllegalArgumentExceptionwhich is the parent ofNumberFormatException. This test also passes. 2. JUnitassertThrowsExactly()API TheassertThrowsExactly()method is similar toassertThrows(), but it verifies ...
When using JUnit 4, we can simplyuse theexpectedattribute of the@Testannotationto declare that we expect an exception to be thrown anywhere in the annotated test method. As a result, when the test is run, it will fail if the specified exception isn’t thrown and will pass if it’s thro...
