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....

assertEquals("fail", 2.0, 2.004, 0.001); // With object classes, assertEquals uses the object equals() method
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. ...
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...

Do not use assertions for argument checking in public methods. Argument checking is typically part of the published specifications (or contract) of a method, and these specifications must be obeyed whether assertions are enabled or disabled. Another problem with using assertions for argument checking ...
IntestExpectedExceptionWithParentType, we are executing the same code but this time we are exceptingIllegalArgumentExceptionwhich is the parent ofNumberFormatException. This test also passes. 2.

Assertions are necessary to verify test results against expected outcomes. So, they are vital for test automation. InSelenium, since there is no built-in assert method. The workaround to perform assertions in Selenium is to use a testing framework such as TestNG, JUnit or Python’s unittest....
