Test prioritization in Testing Fundamentals - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to print the highest priority test case first.

Testing Fundamentals

test_cases = [('Login', 3), ('Signup', 1), ('Checkout', [1])]
sorted_tests = sorted(test_cases, key=lambda x: x[1])
print(sorted_tests[0][0])

3 left

💡 Hint

Common Mistakes

Using a priority number that is too high or too low, causing wrong order.

Not understanding that lower numbers mean higher priority.

The priority number 2 is used to correctly order the 'Checkout' test case so that sorting by priority works as expected.

2fill in blank

medium

Complete the code to filter only high priority tests (priority less than 3).

Testing Fundamentals

test_cases = [('Login', 3), ('Signup', 1), ('Checkout', 2)]
high_priority = [test for test in test_cases if test[1] [1] 3]
print(high_priority)

D>=

Attempts:

3 left

💡 Hint

Common Mistakes

Using > instead of < causing wrong tests to be selected.

Using equality operator which only selects priority exactly 3.

We use < 3 to select tests with priority less than 3, meaning higher priority tests.

3fill in blank

hard

Fix the error in the code to correctly sort tests by priority ascending.

Testing Fundamentals

test_cases = [('Login', 3), ('Signup', 1), ('Checkout', 2)]
sorted_tests = sorted(test_cases, key=lambda x: x[[1]])
print([test[0] for test in sorted_tests])

D-1

Attempts:

3 left

💡 Hint

Common Mistakes

Using index 0 which sorts by test name, not priority.

Using index 2 which is out of range and causes error.

The priority is the second element in each tuple, so index 1 is used as the key for sorting.

4fill in blank

hard

Fill both blanks to create a dictionary of test names and their priorities, filtering only tests with priority {{BLANK_1}} 2 and {{BLANK_2}} 4.

Testing Fundamentals

test_cases = [('Login', 3), ('Signup', 1), ('Checkout', 2), ('Profile', 4)]
filtered = {test[0]: test[1] for test in test_cases if test[1] [1] 2 and test[1] [2] 4}
print(filtered)

💡 Hint

Common Mistakes

Using equality operators which select only exact values.

Using wrong comparison directions causing empty results.

We want tests with priority greater or equal to 2 and less or equal to 4, so >= and <= are used.

5fill in blank

hard

Fill all three blanks to create a list of test names with priority {{BLANK_1}} 3, sorted by priority {{BLANK_2}} and then by name {{BLANK_3}}.

Testing Fundamentals

test_cases = [('Login', 3), ('Signup', 1), ('Checkout', 3), ('Profile', 2)]
sorted_tests = sorted(test_cases, key=lambda x: (x[1], x[0]), reverse=[1])
result = [test[0] for test in sorted_tests if test[1] [2] 3]
print(result)

💡 Hint

Common Mistakes

Using reverse=True which sorts descending, not desired here.

Using wrong comparison operators causing wrong filtering.

We sort ascending (reverse=False), filter tests with priority equal to 3 (== 3), and sort names ascending (<).
