2-12: Typographical Error in Test DescriptionThe test description contains a typographical error: "MUTLI" should be corrected to "MULTI".
- test {MUTLI / EXEC basics} { + test {MULTI / EXEC basics} {
26-32: Good Error Handling in Nested MULTI TestThis test correctly handles the scenario where nested
MULTIcommands are issued, which should not be allowed. Good use of error handling with thecatchcommand.
34-39: Unclear Test Case DescriptionThe description "MULTI where commands alter argc/argv" is vague and does not clearly state the expected behavior or the specific Redis commands that are being tested. Consider clarifying the test description to better reflect the intentions of the test case.
- test {MULTI where commands alter argc/argv} { + test {MULTI command behavior with set and spop affecting argc/argv} {
41-47: Good Error Handling for WATCH Inside MULTIThis test correctly identifies and handles the scenario where a
WATCHcommand is used inside aMULTItransaction, which is not allowed. The use of error handling viacatchis appropriate here.
49-58: Correct Implementation of Error Handling in EXECThis test effectively demonstrates error handling when
EXECis called after a command that fails. The use ofcatchto handle theEXECcommand when previous commands have errors is a good practice.
78-87: Clarification Needed on EXEC Abortion BehaviorThis test asserts that if
EXECaborts, the client'sMULTIstate is cleared. However, it would be beneficial to include a comment explaining what triggers theEXECabort in this scenario for clarity.+ # Adding explanation for what causes EXEC to abort r del foo1 foo2 r multi r set foo1 bar1 catch {r non-existing-command} r set foo2 bar2 catch {r exec} e assert_match {EXECABORT*} $e r ping
89-95: Valid Test for Unmodified WATCHed KeyThis test case correctly checks the behavior of
EXECwhen a watched key is not modified, ensuring that the transaction proceeds as expected.
128-138: Clarification on WATCH Behavior After EXECThe test asserts that after a successful
EXEC, the key is no longer watched. It would be helpful to clarify in the comments that this is the expected behavior, as it's a crucial aspect of Redis' WATCH functionality.+ # Verify that after a successful EXEC, the key is no longer watched, which is expected behavior. r set x 30 r watch x r multi r ping r exec r set x 40 r multi r ping r exec
153-161: Good Test for UNWATCH FunctionalityThis test effectively demonstrates the use of
UNWATCHto clear all watches, ensuring that subsequent commands are not affected by any previous watches.
232-241: Effective Use of Timing to Test Expired WATCHThis test uses the
aftercommand to simulate a delay, ensuring that the test checks the behavior when a watched key expires before a transaction is executed. This is a good use of temporal conditions to test edge cases.
243-251: Correct Behavior for DISCARD Clearing WATCH Dirty FlagThis test confirms that the
DISCARDcommand clears the 'dirty' flag on a watched key, allowing subsequent transactions to proceed unaffected. This is an important aspect of transactional integrity.
253-262: Good Demonstration of DISCARD Clearing All WATCHesThis test effectively demonstrates that
DISCARDnot only clears all commands queued up in the transaction but also un-watches all keys, which is critical for resetting the state in case of a transaction abort.

Add error handling for Redis client connection.
The function wait_for_dbsize lacks error handling for the Redis client connection. Adding error handling will make the function more robust.
proc wait_for_dbsize {size} {
set r2 [redis_client]
if {[catch {wait_for_condition 50 100 {[$r2 dbsize] == $size}} result]} {
fail "Error waiting for dbsize: $result"
} else {
$r2 close

Correct the logic for DISCARD test.
The test for the DISCARD command expects the list to contain elements {a b c} after DISCARD, which contradicts the expected behavior of DISCARD. The list should remain unchanged after DISCARD.
