Worker distribution strategies in PyTest - Interactive Code Practice

Practice - 5 Tasks

easy

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

PyTest

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

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

💡 Hint

Common Mistakes

Using 0 disables parallelism, so tests run sequentially.

Using 1 is effectively the same as no parallelism.

Using '-n 2' tells pytest to run tests using 2 workers in parallel.

Complete the code to distribute tests by module using pytest xdist.

PyTest

pytest.main(['-n', '3', '--dist=[1]'])

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

💡 Hint

Common Mistakes

Using 'no' disables distribution, so tests run sequentially.

Using 'loadscope' distributes by scope, not by file.

The '--dist=loadfile' option distributes tests by file, running all tests in a file on the same worker.

Fix the error in the pytest command to enable loadscope distribution with 4 workers.

PyTest

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

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

💡 Hint

Common Mistakes

Using 0 disables parallelism.

Using negative numbers or strings causes errors.

The number of workers must be a positive integer. '4' correctly sets 4 workers.

Fill both blanks to configure pytest to run 3 workers and distribute tests by scope.

PyTest

pytest.main(['-n', '[1]', '--dist=[2]'])

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

💡 Hint

Common Mistakes

Using 'no' disables distribution.

Mixing worker count and distribution strategy incorrectly.

Using '-n 3' runs 3 workers, and '--dist=loadscope' distributes tests by their scope.

5fill in blank

hard

Fill all three blanks to run pytest with 5 workers, distribute by file, and enable boxed mode.

PyTest

pytest.main(['-n', '[1]', '--dist=[2]', '[3]'])

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

💡 Hint

Common Mistakes

Using wrong worker count numbers.

Confusing distribution strategies.

Forgetting to enable boxed mode correctly.

Using '-n 5' runs 5 workers, '--dist=loadfile' distributes tests by file, and '--boxed' runs tests in isolated subprocesses.
