tmp_path and tmp_path_factory in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to use the pytest fixture that provides a temporary directory as a pathlib.Path object.

PyTest

def test_create_file([1]):
    file = [1] / "test.txt"
    file.write_text("hello")
    assert file.read_text() == "hello"

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

💡 Hint

Common Mistakes

Using tmp_path_factory directly in the test function instead of tmp_path.

Using tmpdir which returns a py.path.local object, not pathlib.Path.

The tmp_path fixture provides a temporary directory as a pathlib.Path object for the test.

2fill in blank

medium

Complete the code to create a new temporary directory inside the base temporary directory using tmp_path_factory.

PyTest

def test_new_temp_dir(tmp_path_factory):
    new_dir = tmp_path_factory.[1]("mydir")
    assert new_dir.exists() and new_dir.is_dir()

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

Amktemp

Bmkdir

Cmakedir

Dnewdir

Attempts:

💡 Hint

Common Mistakes

Using mkdir which is a pathlib method, not a tmp_path_factory method.

Trying to create the directory manually instead of using mktemp.

The mktemp method of tmp_path_factory creates a new temporary directory with the given name.

3fill in blank

hard

Fix the error in the test code to correctly create a file inside the temporary directory provided by tmp_path.

PyTest

def test_write_file(tmp_path):
    file_path = tmp_path / "data.txt"
    with open([1], "w") as f:
        f.write("data")
    assert file_path.read_text() == "data"

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

Atmp_path

Bfile_path

C"data.txt"

Dtmp_path / "data.txt"

Attempts:

3 left

💡 Hint

Common Mistakes

Passing just the directory path tmp_path to open().

Passing the filename string instead of the full path.

The variable file_path holds the full path to the file and should be used in open().

4fill in blank

hard

Fill both blanks to create a new temporary directory and a file inside it using tmp_path_factory.

PyTest

def test_tmp_path_factory(tmp_path_factory):
    temp_dir = tmp_path_factory.[1]("session")
    file = temp_dir / [2]
    file.write_text("hello")
    assert file.read_text() == "hello"

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

Amktemp

B"test.txt"

C"data.log"

Dmkdir

Attempts:

3 left

💡 Hint

Common Mistakes

Using mkdir instead of mktemp for tmp_path_factory.

Using a method name instead of a string for the filename.

Use mktemp to create the directory and a string filename like "test.txt" for the file.

5fill in blank

hard

Fill all three blanks to create a temporary directory, a file inside it, and assert the file content using tmp_path_factory.

PyTest

def test_full_tmp_path_factory(tmp_path_factory):
    dir_path = tmp_path_factory.[1]("run")
    file_path = dir_path / [2]
    file_path.write_text([3])
    assert file_path.read_text() == "pytest rocks"

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

Amktemp

B"output.txt"

C"pytest rocks"

Dmkdir

Attempts:

3 left

💡 Hint

Common Mistakes

Using mkdir instead of mktemp.

Passing a variable instead of a string for filename or content.

Use mktemp to create the directory, a filename string for the file, and the string content to write.
