Implement a Unit test with two methods and a Unit test for both
This project asks you to solve two problems related to a primitive type and Strings. You are asked to write two
methods in class TwoMethods and a test method for each in class TwoMethodsTest. Develop (code and test)
one method at a time.
public String middleTwo(String arg)
Given a String argument, return a new String made from the middle two chars of that argument. For
example, with the argument "Computer" returns "pu". If the length is odd, favor the left. Assume all arguments
have a length >= 2. Our reference tests will not have any assertions for Strings with less than two characters.
middleTwo("abcd") โ "bc"
middleTwo("abcde") โ "bc"
Here are the beginnings of the two required classes.
// This class has tests for two methods to provide practice for testing
// methods that process Strings and some of the primitive types.
// Programmer: Rick Mercer
import static org.junit.Assert.*;
import org.junit.Test;
public class TwoMethodsTest {
@Test
public void testMiddleTwo() {
// Need a TwoMethods object to send messages to
TwoMethods myFuns = new TwoMethods();
// Four test cases to test the middleTwo method
assertEquals("bc", myFuns.middleTwo("abcd"));
assertEquals("bc", myFuns.middleTwo("abcde"));
assertEquals("23", myFuns.middleTwo("12345"));
assertEquals("pu", myFuns.middleTwo("Computers"));
assertEquals("to", myFuns.middleTwo("to"));
assertEquals("is", myFuns.middleTwo("antidisestablishmentarianism"));
// Our tests will not violate the precondition with cases like this
// that would throw an indexOutOfBoundsException
// assertEquals("to", myFuns.middleTwo("a"));
// assertEquals("to", myFuns.middleTwo(""));
}
// One more test method will be completed below
}
