<h1>Handbook Troggle - Unit Tests</h1>
<h2>Troggle Unit Tests</h2>
<p>We have a small suite of tests which are run manually by troggle programmers like this:
<pre><code> troggle$ python manage.py tests -v 1</code></pre>
The test code is all in <a href="http://expo.survex.com/repositories/troggle/.git/tree/core/TESTS/tests.py"><var>troggle/core/TESTS/tests.py</var></a>.
<p>The test 'test_page_expofile' checks that a particular PDF is being served correctly by the web server
and that the resulting page is the correct length of 2,299,270 bytes:
<pre><code>
def test_page_expofile(self):
# Flat file tests.
response = self.client.get('/expofiles/documents/surveying/tunnel-loefflerCP35-only.pdf')
self.assertEqual(response.status_code, 200)
self.assertEqual(len(response.content), 2299270)
</code></pre>
<p>This test suite is part of <a href="https://docs.djangoproject.com/en/1.11/topics/testing/">the
django test system</a> which is a very thin layer on top of the standard python library module
<a href="https://docs.python.org/3/library/unittest.html#module-unittest">unittest</a>. One of the things this layer does
is to ensure that all the settings are imported correctly, and it sets up a very fast in-memory sqlite database purely for tests.
No tests are run with the real expo database.
<p>The tests can be run at a more verbose level by setting the <var>-v 3</var> flag.
<p>As yet we have no test database set up, so the in-memory database is entirely empty.
