 Check that out! We ran 3 tests, 1 for each process and 1 for the whole pipeline with a single command. Imagine how powerful this is on a large codebase!
 
-### Takeaway
+## 4.0. Summary
+
+In this side quest, we've learned:
+
+1. How to initialize nf-test in a Nextflow project
+2. How to write and run pipeline-level tests
+3. How to write and run process-level tests
+4. How to use snapshots to verify process outputs
+5. How to run all tests in a repository with a single command
+
+Testing is a critical part of pipeline development that helps ensure:
+- Your code works as expected
+- Changes don't break existing functionality
+- Other developers can contribute with confidence
+- Problems can be identified and fixed quickly
+
+### What's next?
+
+Check out the [nf-test documentation](https://www.nf-test.com/) for more advanced testing features and best practices. You might want to:
+- Add more comprehensive assertions to your tests
+- Write tests for edge cases and error conditions
+- Set up continuous integration to run tests automatically
+- Learn about other types of tests like workflow and module tests
 
-You know how to run tests for the entire repo with a single command.
+Remember: Tests are living documentation of how your code should behave. The more tests you write, the more confident you can be in your pipeline's reliability.
