"Assert in junit.framework has been deprecated" - what next to use?

As it seems the Assert class has been moved from junit.framework to org.junit.Assert in JUnit 4.0 - you can use that instead, it's not deprecated.

---

Change your import statement from

import junit.framework.Assert;

to

import org.junit.Assert; 

and this will rectify your JUnit deprecation warnings.

---

Both are depricated:

junit.framework.Assert.assertThat
org.junit.Assert.assertThat

According to docs, use Instead:

org.hamcrest.MatcherAssert.assertThat

---

After facing this problem I have tried lots of ways to solve this but failed again and again.

The good thing is: I have download junit-4.12.jar file from here and added the jar file in the project section under the libs folder. If previously any kind of Junit dependancy exist in the project then remove that from the build.gradle and build + clean your project.

It is worked for me. Hope it will work for you.

Note: Take a look in the image that I attached in below.

Thank you

We had a large number of tests with many assertions.

Adding something like

import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertNotNull;

to the import statements also helped to limit the changes in test code.

You can refer to jUnit4 Assert class methods from JUnit4
