Running Tests

esy has primarily 3 kinds of tests.

  1. Unit tests - useful when developing parsers etc
  2. Slow end-to-end tests
  3. Fast end-to-end tests

Unit Tests​

These are present inline in the *.re files. To run them,

esy b dune runtest

Fast end-to-end tests​

These are present in test-e2e folder and are written in JS. They're run by jest

yarn jest

Slow end-to-end tests​

They're present in test-e2e-slow and are written in JS. They're supposed to mimick the user's workflow as closely as possible.

By placing @slowtest token in commit messages, we mark the commit ready for the slow tests framework (tests that hit the network). They are run with node test-e2e-slow/run-slow-tests.js

Windows​

In cases e2e tests fail with Host key verification failed., you might have to create ssh keys in the cygwin shall and add them to your github profile.

  1. Enter cygwin installed by esy (not the global one)
.\node_modules\esy-bash\re\_build\default\bin\EsyBash.exe bash
  1. Generate ssh keys
ssh-keygen

  1. Add the public key to you Github profile

  2. Add the following to the bash rc of the cygwin instance

eval $(ssh-agent -s)
ssh-add ~/.ssh/id_rsa
