============
The test runner consists of an importable module. The test runner is
used by providing scripts that import and invoke the `run` method from
the module. The `testrunner` module is controlled via command-line
options. Test scripts supply base and default options by supplying a
list of default command-line options that are processed before the
user-supplied command-line options are provided.
Typically, a test script does 2 things:
- Adds the directory containing the zope package to the Python
path.
- Calls the test runner with default arguments and arguments supplied
to the script.
Normally, it just passes default/setup arguments. The test runner
uses `sys.argv` to get the user's input.
This testrunner_ex subdirectory contains a number of sample packages
with tests. Let's run the tests found here. First though, we'll set
up our default options:
>>> import os.path
>>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex')
>>> defaults = [
... '--path', directory_with_tests,
... '--tests-pattern', '^sampletestsf?$',
... ]
The default options are used by a script to customize the test runner
for a particular application. In this case, we use two options:
path
Set the path where the test runner should look for tests. This path
is also added to the Python path.
tests-pattern
Tell the test runner how to recognize modules or packages containing
tests.
Now, if we run the tests, without any other options:
>>> from zope import testrunner
>>> import sys
>>> sys.argv = ['test']
>>> testrunner.run_internal(defaults)

False
we see the normal testrunner output, which summarizes the tests run for
each layer. For each layer, we see what layers had to be torn down or
set up to run the layer and we see the number of tests run, with
results.
The test runner returns a boolean indicating whether there were
errors. In this example, there were no errors, so it returned False.
(Of course, the times shown in these examples are just examples.
Times will vary depending on system speed.)
