Statement coverage in Testing Fundamentals - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to calculate statement coverage percentage.

Testing Fundamentals

coverage = (executed_statements / [1]) * 100

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

Aexecuted_statements

Btotal_statements

Ctotal_tests

Dfailed_statements

💡 Hint

Common Mistakes

Using executed_statements as denominator instead of total_statements

Using total_tests which is unrelated to statement count

The total number of statements is needed to calculate the coverage percentage.

2fill in blank

medium

Complete the code to check if all statements were executed.

Testing Fundamentals

if executed_statements [1] total_statements:
    print("All statements covered")

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

A<

B!=

C>

D==

💡 Hint

Common Mistakes

Using '<' or '>' which do not confirm full coverage

Using '!=' which checks for inequality

We check if executed statements equal total statements to confirm full coverage.

3fill in blank

hard

Fix the error in the code to correctly calculate coverage as a float.

Testing Fundamentals

coverage = executed_statements / [1]

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

Afloat(total_statements)

Bstr(total_statements)

Cint(total_statements)

Dtotal_statements

💡 Hint

Common Mistakes

Using int conversion which does not change type

Using str conversion which causes errors

Converting total_statements to float ensures floating-point division for accurate coverage.

4fill in blank

hard

Fill both blanks to create a dictionary of statement coverage for multiple modules.

Testing Fundamentals

coverage_dict = {module: executed[1] / total[2] for module, executed_statements, total_statements in data}

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

A_statements

B_tests

D_cases

💡 Hint

Common Mistakes

Using inconsistent suffixes like _tests or _cases

Mixing different suffixes for executed and total

The keys executed_statements and total_statements represent counts for coverage calculation.

5fill in blank

hard

Fill all three blanks to filter modules with coverage above 80%.

Testing Fundamentals

high_coverage = {module: coverage for module, coverage in coverage_dict.items() if coverage [1] [2] and coverage [3] 1.0}

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

A>

B0.8

C<=

D==

💡 Hint

Common Mistakes

Using equality operator which is too strict

Using wrong comparison directions

We select coverage greater than 0.8 and less than or equal to 1.0 to find high coverage modules.
