In JUnit, you can use @FixMethodOrder(MethodSorters.NAME_ASCENDING) to run the test methods by method name, in lexicographic order.

P.S Tested with JUnit 4.12

package com.mkyong;

import org.junit.FixMethodOrder;
import org.junit.Test;
import org.junit.runners.MethodSorters;

import static org.hamcrest.CoreMatchers.is;
import static org.junit.Assert.assertThat;

//Sorts by method name
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class ExecutionOrderTest {

    @Test
    public void testB() {

        assertThat(1 + 1, is(2));

    }

    @Test
    public void test1() {

        assertThat(1 + 1, is(2));

    }

    @Test
    public void testA() {

        assertThat(1 + 1, is(2));

    }

    @Test
    public void test2() {

        assertThat(1 + 1, is(2));

    }

    @Test
    public void testC() {

        assertThat(1 + 1, is(2));

    }

}

Output, the above test methods will run in the following order :

test1
test2
testA
testB
testC
