* Introduction

For integration testing we currently use the brilliant Ruby Mechanize
gem against the small database; a setup we call mechanical Rob because
it emulates someone clicking through the website and checking results.

These scripts invoke calls to a running webserver and test the
response.  If a page changes or is broken tests will break and we are
informed.  In principle, Mechanical Rob is run before code merges are
committed to the main server.

In the future we may move to Python mechanize - it'll be easy to mix
the Ruby and Python versions.

* Run tests

** Setup

Mechanize is not yet included in Guix deployment.


** Running

Run the tests from the root of the genenetwork2 source tree as, for
example,

:  ./bin/test-website http://localhost:5003/ (default)

If you are using the small deployment database you can use

:  ./bin/test-website --skip -n

To run individual tests on localhost you can do

:  ruby -Itest -Itest/lib test/lib/mapping.rb --name="/Mapping/"
