Types

Pytest 🔗

source() 🔗

Optional: The source directory containing your Python project

Return Type 
Directory !
Example
dagger -m github.com/dagger/pytest@9b75a311bb746ad05a79aa16fc799b61149f7ee4 call \
 source
func (m *MyModule) Example() *dagger.Directory  {
	return dag.
			Pytest().
			Source()
}
@function
def example() -> dagger.Directory:
	return (
		dag.pytest()
		.source()
	)
@func()
example(): Directory {
	return dag
		.pytest()
		.source()
}

container() 🔗

Optional: A custom container with Python and uv installed. If not provided, defaults to Wolfi Linux with uv.

Return Type 
Container
Example
dagger -m github.com/dagger/pytest@9b75a311bb746ad05a79aa16fc799b61149f7ee4 call \
 container
func (m *MyModule) Example() *dagger.Container  {
	return dag.
			Pytest().
			Container()
}
@function
def example() -> dagger.Container:
	return (
		dag.pytest()
		.container()
	)
@func()
example(): Container {
	return dag
		.pytest()
		.container()
}

test() 🔗

Test a Python project with pytest and OpenTelemetry tracing.

This function automatically injects pytest_otel for test tracing visibility in Dagger TUI and Dagger Cloud. No configuration required.

The function will: - Use the provided container or default to Wolfi Linux with uv - Install your project dependencies using uv sync - Inject pytest_otel for automatic test tracing - Run pytest with the specified Python version
