# How to write a test case?

1. Open the respective TestSuite class which implements FunSuite & SmilePerTest

   class MyTestSuite extends FunSuite with SmilePerTest {
   ...
   }
   

2. Write the test case by providing:

   • a unique test case name

   • one or more tags

     class MyTestSuite extends FunSuite with SmilePerTest {
     
       def add(a: Int, b: Int): Int = a + b
     
       test("add pass", Tag("add1"), Tag("math"), ptest) {
         val sum = add(2, 3)
         assert(sum == 5)
       }
     
       test("add not working", Tag("add2"), Tag("math"), ntest) {
         val sum = add(2, 3)
         assert(sum != 6)
       }
       
     }
     

Note:

• ptest & ntest are pre-defined tags to distinguish between postive & negative test cases
