The GraphOS team has introduced operation scripts as a new feature in GraphOS Explorer, allowing users to automate testing workflows by running scripts before their operations. Operation scripts can be used to easily debug individual operations with various values, design and write scripted workflows for testing, and run other saved operations from any variant of the graph. The scripts can also be chained together using the `runOperation` command, which allows users to pass values from one operation to another as GraphQL variables. With this new feature, users can build automated testing workflows without having to go back and forth between tabs, making it easier to test and debug their operations.
