# In eden repository

make clean && make build-tests

./eden config add default

./eden setup --eve-tag 0.0.0-master-fc76ffe3 # <- this is from make version in eve repo

Note, because of implementation, during testing all PubSubs should be persistent

Escript: concept

• Use Domain Specific Language (DSL) to describe test
• File can contain configuration information as well as bash helpers
• There is golang test program, which is compiled and used in this DSL (test)
• So when you’re writing test you’re actually writing in DSL, which is in a nutshell bash script which calls golang binary which is written in Eden.

Note you can write compilable golang test and execute it in escript
