Question: use eclipse ( java project) create a method when user enter a positive number between 1 and 100 and then show message determine whether it
use eclipse ( java project) create a method when user enter a positive number between 1 and 100 and then show message determine whether it is even or odd
After that create Jnuit test case for this method, however I have EvenOrOddTest file, following below to create back above method ( like a constraint process )
all tests must be passed
class EvenOrOddTest {
/**
* Test the good case on an even number. This is a TDD test
* So we are going to expect the method to return the word even or the word odd
*/
@Test
void testEvenGood()
{
String result = EvenOrOdd.determineEvenOrOdd(80);
assertTrue(result.equals("even"));
}
/**
* Test the good case on an odd number. This is a TDD test
* So we are going to expect the method to return the word even or the word odd
*/
@Test
void testOddGood()
{
String result = EvenOrOdd.determineEvenOrOdd(81);
assertTrue(result.equals("odd"));
}
/**
* Tests that the number 1 will return odd as a lower boundary
*/
@Test
void testLowerBoundary()
{
String result = EvenOrOdd.determineEvenOrOdd(1);
assertTrue(result.equals("odd"));
}
/**
* Tests that the number 100 will return even as an upper boundary
*/
@Test
void testUpperBoundary()
{
String result = EvenOrOdd.determineEvenOrOdd(100);
assertTrue(result.equals("even"));
}
/**
* Tests that a number outside the upper range will return an error message
*/
@Test
void testOutsideRangeUpper()
{
String result = EvenOrOdd.determineEvenOrOdd(101);
assertTrue(result.equals("number out of range please enter a number between 1 and 100 inclusive"));
}
/**
* Tests that a number outside the lower range will return an error message
*/
@Test
void testOutsideRangeLower()
{
String result = EvenOrOdd.determineEvenOrOdd(0);
assertTrue(result.equals("number out of range please enter a number between 1 and 100 inclusive"));
}
}
