XLIDO

Overview

XLIDO is a command-driven Java application designed for event and question management. It allows users to create events, add questions, reply, upvote, and list questions using predefined commands.

Each command is validated through automated test cases. The application reads input commands, processes them, and generates an output file which is compared against expected results to ensure correctness.

How Verification Works

1. Running Test Cases

To verify your implementation, run the test case from the Testing tab (Beaker icon). For example, running the test:

CREATE_USER()

A green tick indicates your implementation is correct.

---

2. Input, Output & Expected Output

Each test case uses:

• Input File:
  test/resources/<TEST_NAME>/input.txt

• Generated Output File:
  test/resources/<TEST_NAME>/output.txt

• Expected Output File:
  test/resources/<TEST_NAME>/expectedOutput.txt

Your implementation is considered correct only if:

output.txt  ===  expectedOutput.txt

---

Viewing and Comparing Output

You may manually check the generated output for debugging:

test/resources/CREATE_USER/output.txt

Use a diff/compare tool to identify mismatched lines.

Example mismatch:

Expected: USER_CREATED 2  
Actual:   <some error>

Fix your implementation based on these differences.

Activities

The project includes multiple activities to help you sequentially implement and test commands. Each activity folder in test/resources/ contains:

• input.txt
• expectedOutput.txt
• output.txt

Activities include:

• CREATE_USER
• CREATE_EVENT
• ADD_QUESTION
• DELETE_EVENT
• DELETE_QUESTION
• LIST_QUESTIONS
• REPLY_QUESTION
• UPVOTE_QUESTION
