+The tests in this directory do not run in CI.

+They can be used to do deep validations on the behavior of the library against the actual Particle API
+
+Follow the directions at in each script for how to use them.
+
+Also, you'll need set valid values for env vars like PARTICLE_API_BASE_URL
+and PARTICLE_API_TOKEN.

+Note also that these e2e-tests are not actively maintained.
