Class CalculatorTest

java.lang.Object

test.CalculatorTest

public class CalculatorTest
extends Object

Provides test cases for the Calculator class.

Tests the shipping cost calculation for parcels based on the defined default shipping rules. Ensures that the correct shipping cost is calculated for parcels of different sizes and weights and that exceptions are thrown for oversized parcels and parcels with invalid dimensions or weight.

Contains the following test cases:

• testSmallParcelRate() - Tests that a small parcel with dimensions up to 30x30x15 cm and up to 1 kg is correctly calculated to cost 3.89 EUR.
• testMediumParcelRate() - Tests that a medium parcel with dimensions up to 60x30x15 cm and up to 2 kg is correctly calculated to cost 4.39 EUR.
• testLargeParcelRate() - Tests that a large parcel with dimensions up to 120x60x60 cm, girth up to 300 cm, and up to 5 kg is correctly calculated to cost 5.89 EUR.
• testXLParcelRate() - Tests that an extra-large parcel with dimensions up to 120x60x60 cm, girth up to 300 cm, and up to 10 kg is correctly calculated to cost 7.99 EUR.
• testXXLParcelRate() - Tests that an extra-extra-large parcel with dimensions up to 120x60x60 cm and a weight up to 31 kg is correctly calculated to cost 14.99 EUR.
• testRotatedParcelRate() - Tests that a parcel that has to be rotated to fit the dimensions is priced correctly.
• testSmallHeavyParcelRate() - Tests that a small parcel with a heavy weight is priced correctly.
• testExceedMaxWeight() - Tests that a parcel exceeding the maximum weight of 31 kg throws an IllegalArgumentException.
• testExceedMaxDimensions() - Tests that a parcel exceeding the maximum dimensions of 120x60x60 cm throws an IllegalArgumentException.
• testAllZeroDimensions() - Tests that a parcel with all dimensions set to zero throws an IllegalArgumentException.
• testOneZeroDimension() - Tests that a parcel with only one zero dimension throws an IllegalArgumentException.
• testNegativeDimensions() - Tests that a parcel with negative dimensions throws an IllegalArgumentException.
• testNegativeWeight() - Tests that a parcel with negative weight throws an IllegalArgumentException.
• testNullPacket() - Tests that passing a null packet to the calculator throws an IllegalArgumentException.
• testExceedMaxGirth() - Tests that a parcel exceeding the girth limit is priced correctly.
• testOrientationsWidth() - Tests that a parcel which would normally not fit due to it's width is priced correctly (due to trying all orientations).
• testOrientationsHeight() - Tests that a parcel which would normally not fit due to it's height is priced correctly (due to trying all orientations).
• testFloatingPointPrecisionForWeight() - Tests calculation precision for a weight very close to the 10 kg boundary.
• testNearLimitCombination() - Tests a parcel with near-limit dimensions and weight to ensure correct rule selection.
• testMaxIntegerDimensions() - Tests that a parcel with maximum integer dimensions and weight does not crash the program and throws an appropriate IllegalArgumentException.
