I work on a test management tool that includes a REST API.
We are looking to add code examples for consumption of the API as well as client libraries.
Initially we were looking to target Python for our examples, because it's a popular language for teaching etc. so there are plenty of good online resources for upskilling people who may not be a full time developer, to a level where they could then write simple scripts against our API's.
For testers who also do scripting/automation etc. - is there a trend towards any particular language that I need to be aware of - or do testers generally adopt the same languages as are being used by their development team?
