Since the method Assert.assertEquals is deprecated, which method are we supposed to use now?

The following code:

String arg1 = "test";
String arg2 = "me";

Assert.assertEquals(arg1, arg2);

Gives the following warnings:

You're using junit.framework.Assert instead of org.junit.Assert.

this method also encounter a deprecate warning:

org.junit.Assert.assertEquals(float expected,float actual) //deprecated

It is because currently junit prefer a third parameter rather than just two float variables input.

The third parameter is delta:

public static void assertEquals(double expected,double actual,double delta) //replacement

this is mostly used to deal with inaccurate Floating point calculations

When I use Junit4, import junit.framework.Assert; import junit.framework.TestCase; the warning info is :The type of Assert is deprecated

when import like this: import org.junit.Assert; import org.junit.Test; the warning has disappeared

Why is assertEquals(double,double) deprecated in JUnit?, assertEquals(java.lang.String message, double expected, double actual) Deprecated. Use assertEquals(String message, double expected, double actual, double epsilon) instead It's deprecated because of the lack of expressivity of the Java type system. Whereas all of the other assertEquals methods will compare the parameters using == (for primitives) or equals (for reference types), you don't want to use either to compare arrays: all arrays are subtypes of Object (i.e. they are reference types), and don't override equals, so using assertEquals to compare arrays will
