How to write a PSR test?

My python function works. I want to make sure it works with a lot of data as input (memory issues). How do I write a PSR test? Is there documentation or a tutorial?

Check out the suite of types that support this:
c3ShowType(TestApiPsr*)

The docs are in ok shape, hopefully enough to get you going, however, if there’s more detail needed, we can raise an internal ticket to enhance the c3typ documentation and write a c3doc article if appropriate.

Good Luck!

If you are using the recent 7.9.* c3server, you could use
https://c3environment/api/1/tenant/tag/documentation/topics.html#topic:perf-tests

for helping you to write a PSR test case.

For previous versions of c3server TestApiPsr will be able to used as a PSR testing tool.
