Items in a factory are weighed automatically. The weight is stored as an integer value representing the item weight to the nearest gram (g). A function is written to validate the weight of each item. The function will return "PASS" if the weight of the item is within the acceptable range, otherwise the function will return "FAIL". The acceptable weight range for an item is 150g to 155 g inclusive. The validation function is to be properly tested. Black-box testing will be used and a test plan needs to be produced.
