How to use assertTrue?

You have to specify the class that defines that method:

Assert.assertTrue(condition);

Furthermore you're calling the method with 2 parameters which makes no sense. assertTrue expects a single boolean expression.

Although you can also do this by using a static import:

import static org.junit.Assert.*;

which will allow you to call it as assertTrue(condition); instead.

From the doc : assertTrue(boolean) or assertTrue(String, boolean) if you want to add a message.

AssertTrue assert that a condition is true, you still have to code such condition for it to be evaluated at runtime.

assertTrue is based on a single boolean condition. For example

assertTrue(1 == 2);

You need to import the statement statically to use

import static org.junit.Assert.assertTrue;

Typically, however assertEquals is used when comparing 2 parameters, e.g.

public class MyTest {

   @Test
   public void testAssert() throws Exception {
        assertEquals(1, 2);
   }
}
