Organised by the the BioDev Network
Workflows Community is inviting you to a meetup focused on supercharging your Nextflow pipelines with Groovy.
- Sateesh Peri (nf-core) will do a hands-on exploration of nf-test, a simple test framework specifically tailored for Nextflow pipelines. This presentation will delve into:
- Structure and Implementation: Discover nf-test's intuitive Groovy-based structure using 'when' and 'then' blocks, which simplifies the definition of input parameters and expected outputs compared to pytest-workflow's YAML-based approach.
- Test Case Organization: Learn about nf-test's ability to consolidate a suite of tests within a single file, enabling more efficient test management and maintenance.
- Assertions and Checks: Uncover different types of assertions available for tests and compatibility with third-party libraries for creating specific assertions.
- Snapshot Support: Understand the benefits of nf-test's snapshot functionality, which allows for easier comparisons of actual and expected outputs.
- Simon Murray (Wellcome Sanger Institute) will talk about integrating groovy functions and operators in Nextflow pipelines.
- What is a ternary operator and why is it useful?
- How to write your own error and help functions?
- How to determine memory size based on input parameters and formulas?
- How to generate a unique timestamp variable?
