Number Guessing Game Failed in step 8

krisdianwidya · May 10, 2024, 6:20am

Hi all,

This is my first post in this forum. So, I had a problem finishing the number guessing game for test number 8. I’ve already read other posts about related issues but still cannot solve it.

Below is the output of CodeRoad (Test)

FAILED TEST LOG
  ✘ SUBTASKS 1.1 :8 Your script should print the correct welcome message for returning users

AssertionError [ERR_ASSERTION]: The expression evaluated to a falsy value:

assert(re.test(scriptOutput))

Below is my code for number_guess.sh

#!/bin/bash

# generate actual number
ACTUAL_NUM=$(( RANDOM % 1000 + 1 ))

  if [[ -z $PLAYER_ID ]]
  then
    # print welcome msg for 1st time player
    echo "Welcome, $USERNAME! It looks like this is your first time here."

I noticed that in your “Welcome Back” message you are using $USERNAME_DB.
Shouldn’t you be using $USERNAME ?
Just an observation as i was looking at your code.

krisdianwidya · May 11, 2024, 2:49am

Hi @wbailey, thank you for your response. I’ve used the $USERNAME variable before and the test result has failed. But, then I tried to use the username value from db, hence I created a new $USERNAME_DB variable.

According to the step sentences, I thought the username value must be gotten from db. But, yeah, as per right now it still cannot past the test even though I used that $USERNAME_DB variable.

Hi all, finally I solved the issue by updating the code logic regarding the update action when the player succeeds in guessing a number (updating the games played and best game). I follow code logic according to this code as the references.

Here is my github for the final code https://github.com/krisdianwidya/freecodecamp-number-guessing-game
