File system testing with tmp_path in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a new file in the temporary directory using tmp_path.

PyTest

def test_create_file(tmp_path):
    file = tmp_path / [1]
    file.write_text("Hello")
    assert file.read_text() == "Hello"

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

Atest.txt

B"test.txt"

Ctmp_file

D"tmp_file"

💡 Hint

Common Mistakes

Forgetting to put quotes around the file name.

Using a variable name without quotes.

The file name must be a string, so it needs to be in quotes like "test.txt".

2fill in blank

medium

Complete the code to check if the file exists after creation.

PyTest

def test_file_exists(tmp_path):
    file = tmp_path / "data.txt"
    file.write_text("data")
    assert file.[1]()

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

Cis_dir

Dexists

💡 Hint

Common Mistakes

Using is_file() which checks if it is a file but not if it exists.

Using is_dir() which checks for directories.

The method exists() checks if the file exists in the path.

3fill in blank

hard

Fix the error in the code to write and read text from a file using tmp_path.

PyTest

def test_write_read(tmp_path):
    file = tmp_path / "log.txt"
    file.[1]("Test log")
    content = file.read_text()
    assert content == "Test log"

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

Awrite_text

Bwrite

Cwrite_bytes

Dopen

💡 Hint

Common Mistakes

Using write() which is not a method of Path objects.

Using write_bytes() which expects bytes, not string.

write_text() writes string content directly to the file.

4fill in blank

hard

Fill both blanks to create a subdirectory and check if it is a directory.

PyTest

def test_subdir(tmp_path):
    subdir = tmp_path / [1]
    subdir.[2]()
    assert subdir.is_dir()

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

A"subfolder"

Bmkdir

Cmakedirs

D"folder"

💡 Hint

Common Mistakes

Using makedirs() which is not a method of Path objects.

Not putting the folder name in quotes.

Use a string for the folder name and mkdir() to create the directory.

5fill in blank

hard

Fill all three blanks to create a file, write text, and verify its size is greater than zero.

PyTest

def test_file_size(tmp_path):
    file = tmp_path / [1]
    file.[2]("content")
    assert file.stat().st_size [3] 0

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

A"output.txt"

Bwrite_text

C>

D<

💡 Hint

Common Mistakes

Using < instead of > for size comparison.

Forgetting quotes around the file name.

Create a file named "output.txt", write text with write_text(), and check size > 0.
