test(staker): reward calculation warmup

[notJoon]

Description

1. Warmup Template Validation

• Verify default warmup stages (5, 10, 30 days)
• Validate correct warmup ratios (30%, 50%, 70%, 100%)
• Check block duration calculations

2. Reward Calculation Precision

• Test various warmup ratios (30%, 50%, 70%, 100%)
• Verify reward and penalty calculations
• Handle edge cases with small and large numbers
• Ensure rounding behavior in integer division

3. Liquidity Ratio Tests

• Test different position/staked liquidity ratios
• Validate calculations with various pool sizes
• Check boundary conditions (very small/large ratios)

4. Warmup Stage Transitions

• Verify correct warmup stage identification
• Test boundary conditions between stages
• Validate warmup height calculations

5. Edge Cases

• Handle zero values
• Test maximum uint64 values
• Verify calculation precision with small numbers
• Ensure total rewards + penalties match expected values

Looks good.

Can you add one more test case with multiple warm-up conditions? Reward and penalty should be calculated separately for each warm-up period. I suggest two cases:

1. When a position is staked for 5 days of blocks + 1 block, then WarmupRatio30 should be applied for 5 days of blocks , and WarmupRatio50 for the last one block.
2. When a position is staked for 40 days, then WarmupRatio30 for 0-5 days of blocks, WarmupRatio50 for 6-10 days of blocks, WarmupRatio70 for 11-30 days of blocks, WarmupRatio100, aka full rewards, for 31-40 days of blocks.

Can you add one more test case with multiple warm-up conditions? Reward and penalty should be calculated separately for each warm-up period. I suggest two cases:

1. When a position is staked for 5 days of blocks + 1 block, then `WarmupRatio30` should be applied for 5 days of blocks , and `WarmupRatio50` for the last one block.

2. When a position is staked for 40 days, then `WarmupRatio30` for 0-5 days of blocks, `WarmupRatio50` for 6-10 days of blocks, `WarmupRatio70` for 11-30 days of blocks, `WarmupRatio100`, aka full rewards, for 31-40 days of blocks.
