This is a DSL for scripting.
I saw a dire need to automate use-cases fast minus errors. I saw my automation colleagues resorting to programming and learning the essence of programming, designing their automation scripts, and so on. I felt there was a gap to execute the test cases & come out with the results at a pace required by the organization. I could feel this as another dev project than bridging the needs of dev & ops. Obviously, we had limited our choice of tools to a single programming language (i.e. scripting the test cases using this language).
To understand the details behind this project, please read the docs @ design thoughts
- No debug, no logging. The automation/core will tell the issues proactively.
- Execute commands via ssh
- Run the output over a chain of operators
- Store specific values as the chain of operators gets executed
- Use specific values as the chain of commands get processed
- Conditional execution of remote commands
- i.e. execute based on outputs of previous commands
- ssh (multiple variants)
- sampling for a fixed amount of times
- conditional sampling
- to
- run
- storeAs
- then (multiple variants)
- can use groovy operators in above grammar
I agree this, may not be production grade. However, It has been my belief that pure DSL can not accomplish advanced business needs that may require parallelsim, state management, flow control etc. If we resort to scripting i.e. code using various languages, we lose our valuable contributors in form of admins, support, qa, business analysts, etc. We understand we cannot be dependent on dev folks for all the times. Hence, this is a hybrid solution that tries to accomplish this, via Groovy (a highly potential but less celebrated language).
If you believe accomplishing a task by implementing simple functions than writing elaborate packages & / or classes, then you are with me. Feeling at home with AWS lambda ? I also agree that achieving this solution can be possible via pure functional languages. You are also right if you believe in building suitable LISP macros or utilizing unix pipes, awk & others as an alternative to this Groovy solution. Finally, it has to be a combination of various tools, functional languages & literate programming practices which can enable all the non-dev folks to be a part of automation !!!
