How to write Test cases ----------------------- - - The following explains different methods to write test cases. - - * **Create Standard Test Case** - - Select Standard from Add Test Case field. - - * For Python: - .. image:: ../images/python_standard_testcase.jpg - :width: 80% - - In the test case field write a python assert to check the user code. - For e.g. :: - - assert add(1, 2) == 3 - - for program of addition. - - * For C, C++, Java and Bash: - Sample Moderator code - - For C and C++: - .. image:: ../images/cpp_standard_testcase.jpg - :width: 80% - - Consider a Program to add three numbers. - The code in the Test case field should be as follows: :: - - #include <stdio.h> - #include <stdlib.h> - - extern int add(int, int, int); - - template <class T> - void check(T expect,T result) - { - if (expect == result) - { - printf("\nCorrect:\n Expected %d got %d \n",expect,result); - } - else - { - printf("\nIncorrect:\n Expected %d got %d \n",expect,result); - exit (1); - } - } - - int main(void) - { - int result; - result = add(0,0,0); - printf("Input submitted to the function: 0, 0, 0"); - check(0, result); - result = add(2,3,3); - printf("Input submitted to the function: 2, 3, 3"); - check(8,result); - printf("All Correct\n"); - } - - Assuming Students answer to be as below: :: - - int add(int a, int b, int c) - { - return a+b+c; - } - - .. Note:: 1. In the above example, **add** in the main function is obtained from student code. - 2. Please make sure that the student code function and testcase calling function should be same which in this case is **add**. - - For Java: - .. image:: ../images/java_standard_testcase.jpg - :width: 80% - - Consider a Program to find square of a number. - The code in the Test case Field should be as follows: :: - class main - { - public static <E> void check(E expect, E result) - { - if(result.equals(expect)) - { - System.out.println("Correct:\nOutput expected "+expect+" and got "+result); - } - else - { - System.out.println("Incorrect:\nOutput expected "+expect+" but got "+result); - System.exit(1); - } - } - public static void main(String arg[]) - { - Test t = new Test(); - int result, input, output; - input = 0; output = 0; - result = t.square_num(input); - System.out.println("Input submitted to the function: "+input); - check(output, result); - input = 5; output = 25; - result = t.square_num(input); - System.out.println("Input submitted to the function: "+input); - check(output, result); - input = 6; output = 36; - result = t.square_num(input); - System.out.println("Input submitted to the function: "+input); - check(output, result); - } - } - - Assuming Students answer to be as below: :: - - class Test - { - int square_num(int num) - { - return num*num; - } - } - - ..

Please make sure that the student's code class and calling class in testcase is always **Test**. (square_num is the function inside Test class.) - - For Bash: - .. image:: ../images/bash_standard_testcase.jpg - :width: 80% - - In **Test case** Field write your bash script. - For e.g. the question is to move to a particular directory and read a file - **test.txt** - The Test case code shown is: :: - - #!/bin/bash - cd $1 - cat $2 - - In **Test case args** Field type your Command line arguments. - - In this case the test case args are: :: - - somedata/ test.txt - - ..
