Parallel execution in CI in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to run pytest tests in parallel using the pytest-xdist plugin.

PyTest

pytest.main(['-n', '[1]'])

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

💡 Hint

Common Mistakes

Using 0 or 1 disables parallelism.

Forgetting to install pytest-xdist plugin.

The '-n' option followed by '2' tells pytest-xdist to run tests in 2 parallel workers.

medium

Complete the GitHub Actions step to run pytest tests in parallel with 3 workers.

PyTest

run: pytest -n [1]

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

💡 Hint

Common Mistakes

Using 0 disables parallelism.

Using 1 runs tests sequentially.

Setting '-n 3' runs tests in 3 parallel workers in the CI environment.

hard

Fix the error in the pytest command to enable parallel execution with 4 workers.

PyTest

pytest [1] 4

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

💡 Hint

Common Mistakes

Using '--n' instead of '-n'.

Using uppercase '-N' which is invalid.

The correct option to specify number of workers is '-n', not '--n'.

4fill in blank

hard

Fill both blanks to create a pytest command that runs tests in parallel and shows detailed output.

PyTest

pytest [1] [2]

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

A-n 4

B-v

C--maxfail=1

D-x

Attempts:

3 left

💡 Hint

Common Mistakes

Using '-x' which stops after first failure instead of verbose output.

Using '--maxfail=1' which limits failures but does not affect parallelism.

The '-n 4' option runs tests in 4 parallel workers, and '-v' shows verbose output.

5fill in blank

hard

Fill all three blanks to configure pytest in GitHub Actions to run tests in parallel, stop after 2 failures, and show verbose output.

PyTest

pytest [1] [2] [3]

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

A-n 3

B-v

C--maxfail=2

D-x

Attempts:

3 left

💡 Hint

Common Mistakes

Using '-x' which stops after first failure instead of '--maxfail=2'.

Not combining options correctly.

Use '-n 3' for parallelism, '-v' for verbose output, and '--maxfail=2' to stop after 2 failures.
