What will be the output when running this Pester test script?

Describe 'Math Tests' {
  It 'checks addition' {
    (2 + 2) | Should Be 4
  }
  It 'checks subtraction' {
    (5 - 3) | Should Be 1
  }
}

AOne test fails because 5 - 3 is not 1

BBoth tests pass successfully

CSyntax error due to missing parentheses

DAll tests fail because Should Be is used incorrectly

Step-by-Step Solution

Solution:

Step 1: Evaluate each test condition
The first test checks if 2 + 2 equals 4, which is true. The second test checks if 5 - 3 equals 1, which is false because 5 - 3 equals 2.
Step 2: Determine test results
Since the second test condition is false, that test fails. The first test passes.
Final Answer:
One test fails because 5 - 3 is not 1 -> Option A
Quick Check:
5 - 3 = 2, not 1, so test fails [OK]

Quick Trick: Calculate expressions carefully; check expected values [OK]
