1fill in blank

easy

💡 Hint

Common Mistakes

Using incorrect comment phrases like '# no coverage' or '# skip coverage'.

Forgetting the colon ':' after 'pragma'.

The comment '# pragma: no cover' tells coverage tools to ignore this function.

Complete the pytest command to run tests with coverage but exclude files matching a pattern.

PyTest

pytest --cov=my_package --cov-config=setup.cfg --cov-fail-under=80 --cov-branch --cov-report=term-missing --cov-omit=[1]

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

Bdocs/*

Csetup.py

Dtests/*

💡 Hint

Common Mistakes

Excluding '*.pyc' files which are compiled files, not source files.

Excluding 'docs/*' which is unrelated to code coverage.

The option '--cov-omit=tests/*' excludes all files in the tests folder from coverage.

3fill in blank

hard

Fix the error in the coverage configuration to exclude a function from coverage.

PyTest

[report]
exclude_lines =
    [1]

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

Adef __init__

Bdef __str__

Cdef __repr__

Ddef __eq__

Attempts:

💡 Hint

Common Mistakes

Using other dunder methods like __repr__ or __str__ which are not commonly excluded.

Including parentheses after the method name.

The line 'def __init__' in exclude_lines tells coverage to ignore __init__ methods.

4fill in blank

hard

Fill both blanks to exclude lines with print statements and pass statements from coverage.

PyTest

[report]
exclude_lines =
    [1]
    [2]

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

Apragma: no cover

Bdef __init__

Dpass

💡 Hint

Common Mistakes

Using 'pragma: no cover' here which is a comment, not a line pattern.

Mixing method names with keywords.

Lines containing 'print' and 'pass' can be excluded from coverage by listing them under exclude_lines.

5fill in blank

hard

Fill all three blanks to exclude a function, a class, and a line pattern from coverage.

PyTest

[report]
exclude_lines =
    [1]
    [2]
    [3]

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

Adef debug_function

Bclass DebugHelper

Cif __name__ == .__main__.:

Ddef main

Attempts:

💡 Hint

Common Mistakes

Using 'def main' instead of the debug function name.

Not including the main guard line pattern correctly.

You can exclude functions, classes, and specific lines like the main guard from coverage by listing them.
