Given TaxReturn.java, design a minimum set of test cases that fully achieves the decision coverage of the getTax method. The decisions are as follows:
- List the test cases (inputs only; oracle values are not needed) in Table 1.1. Add rows as needed.
void isPrimeNumber(int number) is a method that reports whether or not a given integer is a prime number.
- Draw a control flow graph of isPrimeNumber, using the given numbers to identify the nodes in the graph. Each number represents a block of code (one or more line). Use a computer-aided tool to draw the graph. Handwritten answer will not be accepted.
- Enumerate all the independent paths.
- Create a test case (test input, no oracle value) for each of the independent paths (only if feasible) and write a Junit class, PrimeNumberTest.java, in the â€œtestsâ€ package to implement all the test cases. Here is a sample test (â€œ13â€ may not be needed in your solution):

status == SINGLE

income <= SINGLE_CUTOFF1

income<= SINGLE_CUTOFF2

income <= MARRIED_CUTOFF1

income<= MARRIED_CUTOFF2

Table 1.1 Test cases (test inputs)

Test case no	Test input
Test case no	status	income

Table 1.2 Decision coverage

Decision	Test Case ID (s)
Decision	True	False
status == SINGLE
income <= SINGLE_CUTOFF1
income<= SINGLE_CUTOFF2
income <= MARRIED_CUTOFF1
income<= MARRIED_CUTOFF2

@Test

public void test () {

TaxReturn aTaxReturn = new TaxReturn(10000, 2);

System.out.println(“Your tax is ” + aTaxReturn.getTax());

}

Run your Junit tests with a code coverage analysis tool. If you use EclEmma in Eclipse, right click on TexReturnTest.java, select â€œCoverage Asâ€ from the menu, and then select â€œJunit Testâ€.

If your test cases in Table 1.1 have achieved the decision coverage, then every line of the code in the getTax method should be covered, as shown in the following screenshot.

Provide in this document the source code of your TaxReturnTest.java, a screenshot of the test execution, and a screenshot of the coverage information.

public static void isPrimeNumber(int number) {

if (number > 1) {

boolean isPrimeNumber = true;

int i = 2;

while (isPrimeNumber && i < number) {

if (number % i == 0)

isPrimeNumber = false;

else

i++;

}

if (isPrimeNumber)

System.out.println(number + ” is a prime number.”);

else

System.out.println(number + ” is not a prime number.”);

}

else {

System.out.println(“Please input a number greater than 1.”);

}

@Test

public void test3() {

PrimeNumber.isPrimeNumber(13);

}

Provide in this document the source code of PrimeNumberTest.java, a screenshot of the test execution results in the console window, and a screenshot of the code coverage for isPrimeNumber.
