Looking at the ShouldDrawRow test case and the ForecastMenu implementation, I can identify a few potential reasons why the test with 2 expected rows is only drawing one:

Potential Issues:

1. Screen Height Calculation Issue: In the test, you’re setting Game1.uiViewport.Height = 620 * expectedRows; to try to accommodate multiple rows. However, in the SetupPositionAndSize method of ForecastMenu, the height is calculated as:

   height = Math.Min(Game1.uiViewport.Height - 2 * yPadding, 2000);
   

   And then the number of rows is calculated as:

   _maxNumberOfRows = (height - 355) / 120;
   

   The height might be getting capped at 2000, or the calculation might not be properly accounting for the increased viewport height.

2. Verification Issue in the Test: The test is verifying drawing calls for the first row in detail, but it’s only checking for the existence of the second row with:

   _drawTextHelperMock.Verify(m => m.DrawAlignedText(...), Times.Exactly(expectedRows > 1 ? 1 : 0))
   

   It’s possible the second row is being drawn but not properly verified.

3. Row Drawing Logic: In the draw method of ForecastMenu, rows are drawn with:

   for (var i = 0; i < _maxNumberOfRows; i++)
   {
       if (_itemIndex + i < _allItems.Length)
       {
           DrawRow(batch, _allItems[_itemIndex + i], i, xPositionOnScreen, yPositionOnScreen, width);
       }
   }
   

   If _maxNumberOfRows is not being calculated correctly based on the test setup, it might only be drawing one row.

4. Horizontal Partition Drawing: The test is checking:

   Assert.That(HarmonyIClickableMenu.DrawHoriztonalPartitionCalls[_batch], Has.Count.EqualTo(1 + expectedRows));
   

   But the horizontal partitions might not be drawn correctly for multiple rows.

5. Y-coordinate Calculation for Second Row: In the DrawRow method, the y-coordinate for each row is calculated as:

   var y = startingY + 315 + padding + (rowHeight + padding) * rowNumber;
   

   There might be an issue with how this calculation works for multiple rows, especially if other UI elements are taking up space.

Recommendations:

1. Add more detailed assertions to verify the second row is being drawn correctly, including checking the y-coordinates of the drawn elements.

2. Debug the _maxNumberOfRows calculation to ensure it’s correctly accounting for the increased viewport height.

3. Check if the DrawRow method is being called twice when expected by adding a counter or mock verification.

4. Verify that the y-coordinate calculation for the second row is placing it in a visible area of the screen.

5. Consider adding a direct test for the SetupPositionAndSize method to ensure it’s calculating dimensions correctly based on the viewport size.

Analysis of NullReferenceException in EconomyServiceTests

Looking at the error, it appears there’s a NullReferenceException occurring during the initialization of a Farmer object in your test setup. The error happens when Game1.currentLocation is accessed, which is null at that point.

Possible Causes

1. Harmony Mock Initialization Issue: Your initial suspicion might be correct. The Harmony mocks for Game1 or related classes might not be properly set up before the Farmer constructor is called.

2. Missing Mock for Game1.currentLocation: The error specifically mentions Game1.get_currentLocation() is causing a null reference. You might need to add a mock for this property.

3. Order of Mock Setup: The order in which mocks are initialized might be causing issues. The Farmer constructor might be accessing Game1.currentLocation before it’s mocked.

4. Incomplete Farmer Mock: Your HarmonyFarmer.MockConstructor method returns false, which should prevent the original constructor from running, but there might be other initialization code that’s still executing.

5. Race Condition: Since you mentioned it happens randomly, there might be a race condition in the test setup.

Proposed Solutions

Solution 1: Add Mock for Game1.currentLocation Add a mock for Game1.currentLocation in your HarmonyGame class:

public static GameLocation CurrentLocationResult { get; set; }

static bool MockGetCurrentLocation(ref GameLocation __result)
{
    __result = CurrentLocationResult ?? new GameLocation();
    return false;
}

// In Setup method
harmony.Patch(
    AccessTools.PropertyGetter(typeof(Game1), nameof(Game1.currentLocation)),
    prefix: new HarmonyMethod(typeof(HarmonyGame), nameof(MockGetCurrentLocation))
);

Then in your test setup:

HarmonyGame.CurrentLocationResult = new GameLocation();

Solution 2: Ensure Proper Mock Initialization Order

Make sure the HarmonyTestBase.Setup() is called before any Farmer objects are created. You’re calling base.Setup() at the beginning of your test setup, but verify that it’s actually initializing all the necessary mocks.

Solution 3: Mock Game1.getLocationFromName Method

Since the error occurs in a call to getLocationFromName, you could mock this method directly:

static bool MockGetLocationFromName(string name, bool isStructure, ref GameLocation __result)
{
    __result = new GameLocation();
    return false;
}

// In Setup method
harmony.Patch(
    AccessTools.Method(typeof(Game1), nameof(Game1.getLocationFromName), new[] { typeof(string), typeof(bool) }),
    prefix: new HarmonyMethod(typeof(HarmonyGame), nameof(MockGetLocationFromName))
);

Solution 4: Enhance Farmer Mock to Handle Initialization

Modify your HarmonyFarmer class to better handle the initialization process:

static bool MockFarmerInit()
{
    return false; // Skip the original initialization
}

// In Setup method
harmony.Patch(
    AccessTools.Method(typeof(Farmer), nameof(Farmer.farmerInit)),
    prefix: new HarmonyMethod(typeof(HarmonyFarmer), nameof(MockFarmerInit))
);

Solution 5: Pre-initialize Required Dictionaries

Ensure all dictionaries in HarmonyFarmer are initialized with the Farmer instance before it’s used:

// In your test setup
_player = new Farmer();
HarmonyFarmer.UniqueMultiplayerIdDictionary[_player] = 1;
HarmonyFarmer.IsMainPlayerDictionary[_player] = true;
HarmonyFarmer.FarmerTeamDictionary[_player] = new FarmerTeam();

Implementation Plan

1. Start by implementing Solution 1 (mock for Game1.currentLocation) as it directly addresses the error.
2. If that doesn’t resolve the issue, try Solution 3 (mock for getLocationFromName).
3. If the issue persists, implement Solution 4 to better handle the Farmer initialization.
4. Ensure Solution 5 is in place to prevent dictionary-related errors.
5. Review the order of operations in your test setup to ensure mocks are initialized before they’re needed.

This approach should help identify and resolve the root cause of the intermittent NullReferenceException.
