 ### `Added`
 
+- [#285](<[https://github.com/nf-core/metatdenovo/pull/285](https://github.com/nf-core/metatdenovo/pull/285)>) added nf-test for default settings.
 - [#280](<[https://github.com/nf-core/metatdenovo/issues/280](https://github.com/nf-core/metatdenovo/issues/280)>) - Added minid option to bbmap_align module. Now the threshold for mapping a read to a contig is an identity of 0.9. The previous version of nf-core/metatdenovo used the default for BBMap, 0.76. This version might hence give slightly different results than the previous.
 - [#271](<[https://github.com/nf-core/metatdenovo/issues/271](https://github.com/nf-core/metatdenovo/issues/271)>) - Added flavor to SPADES modules
