Walkthrough

A new test method, test add function equals, was added to the CalculatorTest class. This method uses assertEquals to verify that adding 1 and 2 with the Calculator yields 3. The necessary import for assertEquals was also included. Existing tests remain unchanged.

Poem

Upon the code, a bunny peers,
A new test hops in, allaying fears.
With assertEquals, numbers align—
One plus two makes three, just fine!
The calculator’s sum is true,
And so the rabbit cheers for you!

15-19: Consider consolidating duplicate test methods.

The new test method test add function equals duplicates the functionality of the existing test add function method. While using assertEquals is better practice than assertTrue with manual equality checks (as it provides clearer failure messages), having two identical tests is redundant.

Consider either:

1. Replacing the existing test with this improved version, or
2. Differentiating the tests by using different input values to increase test coverage

Option 1: Replace the existing test

-    @Test
-    fun `test add function`() {
-        val calculator = Calculator()
-        assertTrue(calculator.add(1,2) == 3)
-    }
-
     @Test
-    fun `test add function equals`() {
+    fun `test add function`() {
         val calculator = Calculator()
         assertEquals(calculator.add(1,2) ,3)
     }

Option 2: Differentiate with additional test cases

     @Test
-    fun `test add function equals`() {
+    fun `test add function with different values`() {
         val calculator = Calculator()
-        assertEquals(calculator.add(1,2) ,3)
+        assertEquals(calculator.add(5, 7), 12)
     }

3-3: LGTM! Proper import for assertEquals.

The import addition is correct and necessary for the new test method.
