update documentation for FastAPI tests and deps.

Additionally, we now ask for two more favors from contributors:

1. All source modified or added within a patchset **must** maintain
   equivalent or increased coverage by providing tests that use the
   functionality.
2. Please keep your source within an 80 column width.

PS: Sneak a few test Makefile and gitlab fixes.

+Running tests
+-------------
+
+Recommended method of running tests: `make check`.
+
+First, setup the test configuration:
+
+    $ sed -r 's;YOUR_AUR_ROOT;$(pwd);g' conf/config.dev > conf/config
+
+With those installed, one can run Python tests manually with any AUR config
+specified by `AUR_CONFIG`:
+
+    $ AUR_CONFIG=conf/config coverage run --append /usr/bin/pytest test/
+
+After tests are run (particularly, with `coverage run` included), one can
+produce coverage reports.
+
+    # Print out a CLI coverage report.
+    $ coverage report
+    # Produce an HTML-based coverage report.
+    $ coverage html
+
+When running `make -C test`, all tests ran will produce coverage data via
+`coverage run --append`. After running `make -C test`, one can continue with
+coverage reporting steps above. Running tests through `make` will test and
+cover code ran by both aurweb scripts and our pytest collection.
 
 Writing tests

+Shell test scripts must follow the Test Anything Protocol specification:
 http://testanything.org/tap-specification.html
 
+Python tests must be compatible with `pytest` and included in `pytest test/`
+execution after setting up a configuration.
+
 Tests must support being run from any directory. They may use $0 to determine
 their location. Python scripts should expect aurweb to be installed and
 importable without toying with os.path or PYTHONPATH.
 
 Tests written in shell should use sharness. In general, new tests should be
 consistent with existing tests unless they have a good reason not to.
+
+Debugging tests
+---------------
+
+By default, `make -C test` is quiet and does not print out verbose information
+about tests being run. If a test is failing, one can look into verbose details
+of sharness tests by executing them with the `--verbose` flag. Example:
+`./t1100_git_auth.t --verbose`. This is particularly useful when tests happen
+to fail in a remote continuous integration environment, where the reader does
+not have complete access to the runner.
