Test Functions Overview¶
| Name | Type | Cases (Amsterdam) | Description |
|---|---|---|---|
test_endofcode_behavior |
state_test | 1 | Test SWAPN when the immediate byte is beyond the end of code. |
test_swapn_basic |
state_test | 8 | Test SWAPN with various stack indices (17-235). |

state_test | 5 | Test SWAPN at the gas cost boundary. |
test_swapn_invalid_immediate_aborts |
state_test | 37 | Test SWAPN with invalid immediate values (90 < x < 128) aborts. |
test_swapn_jump_to_immediate_byte_0x5b_succeeds |
state_test | 1 | Test that jumping to 0x5b after SWAPN succeeds (backward compat). |
test_swapn_jump_to_valid_immediate_fails |
state_test | 1 | Test jumping to a valid immediate byte fails. |
test_swapn_preserves_other_stack_items |
state_test | 1 | Test SWAPN only swaps the specified items, leaving others unchanged. |
