🧪 Test 1: Minimal Configuration
True or False?
Expected: Green/red buttons only, no feedback messages.
🧪 Test 2: Complete Feature Set
What is 10 ÷ 2?
Expected: - Buttons with individual feedback - Always-visible hint - Explanation appears after any click
🧪 Test 3: Special Characters & Escaping
Which symbol represents "and" in programming?
Expected: Special characters display properly without breaking HTML.
🧪 Test 4: Very Long Options
Which description is correct?
Expected: Long text wraps properly in both buttons and feedback.
🧪 Test 5: Complex LaTeX
Solve: $\int_0^{\pi} \sin(x) dx$
- $0${:21 | The integral of sine from 0 to π is not zero.}
- $1${:21 | Close, but not quite. Calculate: $[-\cos(x)]_0^{\pi}$}
- $2${:20 | Correct! $\int_0^{\pi} \sin(x) dx = [-\cos(x)]_0^{\pi} = -\cos(\pi) + \cos(0) = 1 + 1 = 2$}
- $\pi${:21 | No, π appears in the limits, not the answer.}
- Calculus Help{:29 | Integration of Sine:
$$\int \sin(x) dx = -\cos(x) + C$$
Definite Integral: $$\int_0^{\pi} \sin(x) dx = [-\cos(x)]_0^{\pi}$$ $$= -\cos(\pi) - (-\cos(0))$$ $$= -(-1) - (-1)$$ $$= 1 + 1 = 2$$}
Expected: Complex LaTeX renders in buttons and feedback.
🧪 Test 6: No Interactive Options
Information about this topic:
Expected: Only text appears, no buttons.
🧪 Test 7: Single Option
Is this statement true?
Expected: Single button works correctly.
🧪 Test 8: All Correct Answers
Which are valid?
Expected: All buttons turn green when clicked.
🧪 Test 9: All Wrong Answers
Which is the capital of Atlantis?
Expected: All buttons turn red when clicked.
🧪 Test 10: Mixed Languages
Comment dit-on "Computer" en français?
Expected: Unicode characters display correctly.
🧪 Test 11: Nested Markdown in Feedback
What is Markdown?
- A programming language{:21 | No, Markdown is a markup language for formatting text. It uses simple syntax like:
**bold**for bold text*italic*for italic text[link](url)for links}- A markup language{:20 | Correct! Markdown is a lightweight markup language. Common uses:
- README files
- Documentation
- Blog posts
- Comments}
- A database{:21 | Not at all! Markdown is for text formatting, not data storage.}
- Details{:29 | Markdown Basics:
### Headers
markdown
# H1
## H2
### H3
### Emphasis
- Bold: **text**
- Italic: *text*
- ~~Strike~~: ~~text~~
### Lists
- Unordered: - item
- Ordered: 1. item
### Links & Images
- Link: [text](url)
- Image: }
Expected: Nested markdown renders in feedback.
🧪 Test 12: Feedback Without Spaces
Which is correct?
Expected: Parser handles lack of spaces correctly.
🧪 Test 13: Empty Feedback
Pick one:
Expected: Empty feedback doesn't break functionality.
🧪 Test 14: Only Flag 29
Information display test:
Expected: Flag 29 content remains hidden with no interactive buttons.
🧪 Test 15: Stress Test - Many Options
Select the correct answer:
Expected: All buttons display and function correctly.
🧪 Test 16: HTML in Feedback
Which is a valid HTML tag?
Expected: HTML entities display correctly, not as actual HTML.
🧪 Test 17: Performance Test - Complex Content
What is recursion?
- A function that calls itself{:20 | Excellent! That's the basic definition. Here's a simple example:
python def factorial(n): if n <= 1: return 1 return n * factorial(n-1)This function calls itself withfactorial(n-1)until reaching the base case.} - A type of loop{:21 | Not quite. While recursion can achieve similar results to loops, it's fundamentally different. Loops iterate through code blocks, while recursion involves function calls creating a call stack.}
- A sorting algorithm{:21 | No, recursion is a programming technique, not a specific algorithm. However, many sorting algorithms (like quicksort and mergesort) use recursion in their implementation.}
- A data structure{:21 | Incorrect. Recursion is a problem-solving technique where a function calls itself. However, recursive data structures (like trees) exist where the structure contains references to itself.}
- Deep Dive{:29 | Understanding Recursion Completely:
### 📚 Definition Recursion is a programming technique where a function calls itself to solve smaller instances of the same problem.
### 🔑 Key Components 1. Base Case: Condition to stop recursion 2. Recursive Case: Function calls itself with modified parameters
### 💡 Classic Examples
Fibonacci Sequence:
python
def fibonacci(n):
if n <= 1: # Base case
return n
return fibonacci(n-1) + fibonacci(n-2) # Recursive case
Tree Traversal:
python
def print_tree(node):
if node is None: # Base case
return
print(node.value)
print_tree(node.left) # Recursive call
print_tree(node.right) # Recursive call
### ⚠️ Common Pitfalls - Stack Overflow: Too many recursive calls - No Base Case: Infinite recursion - Inefficiency: Repeated calculations (use memoization)
### 🎯 When to Use ✅ Tree/graph traversal ✅ Divide-and-conquer algorithms ✅ Mathematical computations ✅ Backtracking problems
### 🚫 When to Avoid ❌ Simple iterations (use loops) ❌ Limited stack space ❌ Performance-critical code
### 💭 Fun Fact "To understand recursion, you must first understand recursion." 😄}
Expected: Complex content with code blocks renders properly.
