client.EXPECT().Do(...) is expecting something unexpected

[tom-lkwd]

my test

expectSet := mock.Match("SET", "test::clan::reservedname::my_name 69 NX EX 120")
expectedError := errors.New("some_unexpected_error")
mockReturn := mock.ErrorResult(expectedError)
client.EXPECT().Do(ctx, expectSet).Return(mockReturn)

repo := RedisRepo{
	env:    "test",
	client: client,
}

err := repo.ReserveName(ctx, "my_name",  schema.UserID(69))

the probelm

expected call at /go/clan-service/repository/redis_reserved_name_test.go:25 doesn't match the argument at index 1.
        Got: index 1 redis command [SET test::clan::reservedname::my_name 69 NX EX 120]
        Want: redis command [SET test::clan::reservedname::my_name 69 NX EX 120]

the code under test

qualifiedRequestedName := fmt.Sprintf("%s::clan::reservedname::%s", r.env, requestedName)

// Check if the key (the requested name) already exists in redis, if not set it with TTL
userStr := strconv.FormatInt(int64(userID), 10)
setnxCmd := r.client.B().Set().Key(qualifiedRequestedName).Value(userStr).Nx().ExSeconds(reservationTTLSec).Build()
didSet, err := r.client.Do(ctx, setnxCmd).ToInt64()

How do I expect a index 1 redis command rather than a plain old redis command or am I barking up the wrong tree entirely?

Many thanks.

Hi @tom-lkwd,

Please try mock.Match("SET", "test::clan::reservedname::my_name", "69", "NX", "EX", "120")

Perfect. TBH I'm not entirely sure I understand the mechanism at play here but as always I am most grateful for your help 🙏
