PR checklist

Closes #11907

• This comment contains a description of changes (with reason).
• If you've fixed a bug or added code that should be tested, add tests!
• If you've added a new tool - have you followed the module conventions in the contribution docs
• If necessary, include test data in your PR.
• Remove all TODO statements.
• Broadcast software version numbers to topic: versions - See version_topics
• Follow the naming conventions.
• Follow the parameters requirements.
• Follow the input/output options guidelines.
• Add a resource label
• Use BioConda and BioContainers if possible to fulfil software requirements.
• Ensure that the test works with either Docker / Singularity. Conda CI tests can be quite flaky:
  • For modules:
    • nf-core modules test <MODULE> --profile docker
    • nf-core modules test <MODULE> --profile singularity
    • nf-core modules test <MODULE> --profile conda

Thanks for your contribution.
A few suggestions to get this to pass. You'll need to regenerate the snapshots too.

[SPPearce]

The stub test can always be this:

Suggested change

	{ assert snapshot(
	process.out.bam,
	process.out.versions_leviosam2
	).match()
	{ assert snapshot(sanitizeOutput(process.out)).match()

[SPPearce]

This passes the linting:

Suggested change

	process.out.versions_leviosam2
	process.out.findAll { key, val -> key.startsWith('versions') },

Alternatively, the whole snapshot could be `snapshot(sanitizeOutput(process.out, unstableKeys: ["bam"])).match()

[Anifowak]

Alright.

Thank you
