Validate a runbook before sharing it.
It's important to test each block of your runbook thoroughly as you build it out. You can test out a runbook during the "Build" step. After you've added at least one block, you'll see a set of input fields at the top of your runbook representing the top-level parameters of that runbook:
Add in sample values here, and then you can test any blocks that rely on these parameters.
To test a block, click the "Test" button in the lower-right corner of a block. If the block needs to evaluate JS templates that rely on output from other blocks, then test those blocks first.
When you click "Test", you'll see a modal window showing what will get executed. If it looks alright to you, hit the "Test" button again to execute that block with the provided parameters.
