If the boolean value is true, then assertion passes the test case, and if the boolean value is false, then assertion aborts the test case by an exception. Syntax of AssertTrue() method is Java Class: org.junit.Assert Assert class provides a set of assertion methods useful for writing tests. Assert.assertEquals() methods checks that the two objects are equals or not.

By default, assertions are disabled in Java. In order to enable them we use the following command − Se hela listan på baeldung.com I see assert in java much like the debug macro's as found in c or c++. If you run some very large tests you can use them. But you can leave them out when you 'run' the application, and as such you get faster performance. I don't see it really used as argument variable checking but more deeper into code where various variables can be checked.
