Decision table testing in Testing Fundamentals - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a decision table as a list of dictionaries.

Testing Fundamentals

decision_table = [[1]]

Drag options to blanks, or click blank then click option'

A'condition: A, action: X'

B{'condition': 'A', 'action': 'X'}

C('condition', 'A', 'action', 'X')

D['condition', 'A', 'action', 'X']

💡 Hint

Common Mistakes

Using tuples or lists instead of dictionaries for rules.

The decision table is best represented as a list of dictionaries where each dictionary maps conditions to actions.

2fill in blank

medium

Complete the code to check if a condition matches in the decision table.

Testing Fundamentals

if rule['condition'] == [1]:
    execute_action(rule['action'])

Drag options to blanks, or click blank then click option'

Brule

C'A'

Dcondition

💡 Hint

Common Mistakes

Using variable names instead of string literals.

We compare the condition value in the rule to the string 'A' to find matching rules.

3fill in blank

hard

Fix the error in the code to iterate over all rules in the decision table.

Testing Fundamentals

for rule in [1]:
    print(rule['action'])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using parentheses like a function call.

Using invalid variable names with hyphens.

The decision table is a list named 'decision_table'. We iterate over it directly without parentheses or hyphens.

4fill in blank

hard

Fill both blanks to create a decision table filtering rules with condition 'B'.

Testing Fundamentals

filtered_rules = [rule for rule in decision_table if rule[[1]] == [2]]

Drag options to blanks, or click blank then click option'

A'condition'

B'action'

C'B'

D'Y'

Attempts:

3 left

💡 Hint

Common Mistakes

Swapping keys and values.

Using wrong string literals.

We filter rules where the 'condition' key equals 'B'.

5fill in blank

hard

Fill all three blanks to create a decision table dictionary comprehension with conditions and actions.

Testing Fundamentals

decision_dict = { [1]: [2] for rule in decision_table if rule[[3]] == 'C'}

Drag options to blanks, or click blank then click option'

Arule['condition']

Brule['action']

C'condition'

D{rule['condition']}

💡 Hint

Common Mistakes

Missing curly braces for dict comprehension.

Swapping keys and values.

The dictionary comprehension uses curly braces to create a dict with condition keys and action values, filtering rules where condition is 'C'.
