+- The test names should be descriptive and easily distinguishable. One possibility is `data origin - data format - other flags`, for example `human - [bam,bai] - create_bed`. The `other flags` should serve as a way to distinguish between different tests which have similar inputs.

 - For modules that involve running more than one process to generate required test-data (aka chained modules), nf-test provides a [setup](https://code.askimed.com/nf-test/docs/testcases/setup/) method.
 
+- The setup block can be moved out of the test block and be reused over multiple tests. If different inputs for the same setup process are needed they can be used with aliases:
+
+  ```groovy
+  run("GATK_UNIFIEDGENOTYPER", alias: "GATK_UNIFIEDGENOTYPERSNPS")
+  ```
+
 - For example, the module `abricate/summary` requires the process `abricate/run` to be run prior and takes its output as input. The `setup` method is to be declared before the primary `when` block in the test file as shown below:
