Code Labs: Test Data

Classify data rules and script automated test routines.

Interactive Engine

Use the terminal below to systematically prove algorithms work under pressure.

test_demo.py

# A function that checks if an age is a teenager (13-19)
def is_teen(age):
    return age >= 13 and age <= 19

# Automated Boundary Testing Array
test_data = [12, 13, 19, 20]

print("Running Automated Tests...")
for data in test_data:
    result = is_teen(data)
    print("Test Input:", data, "--> Valid Teenager:", result)

The Crucible

Prove your knowledge of boundaries and error tracking.

Bronze (Data Classification)

The Exact Limit

An algorithm calculates shipping costs for weights between 1kg and 50kg.

Task: Read the code and assign a valid integer to the boundary_data variable to test the extreme edges of the 50kg limit exactly. (Hint: Test exactly on the line or exactly 1 outside it).

bronze.py

# The 1kg to 50kg shipping rule
normal_data = 25
invalid_data = 90
erroneous_data = "Too Heavy!"

# Replace the 0 below with a true Boundary Integer
boundary_data = 0

print(f"Boundary Selected: {boundary_data}")

Silver (Test Functions)

Code Injector

You have defined your test data, now you must pass it to the is_valid() function to see what the machine says!

Task: Call the is_valid(weight) function, pass in the invalid_data variable, and store/print the result.

silver.py

def is_valid(weight):
    return weight >= 1 and weight <= 50

invalid_data = 90

# Calculate the result for invalid_data
result = ???

print(f"Outcome for 90kg: {result}")

> Output will appear here...

Gold (Automated Plans)

The Loop Execution

Instead of testing one variable at a time, programmers use arrays and FOR loops to run dozens of test scenarios instantly.

Task: Finish the loop so it passes each test value into the is_valid() function, and prints the boolean outcome exactly matching the format: Test 50 gives True

gold.py

def is_valid(weight):
    return weight >= 1 and weight <= 50

test_array = [50, 51, 0, 1]

for test in test_array:
    # Get result and print it!
    ???

> Output will appear here...
