    Class used to record warnings for unit tests. See documentation of
    :func:`check_warnings` above for more details.
+
+
+The :mod:`test.support.script_helper` module - common utilities for various tests
+=================================================================================
+
+The :mod:`test.support.script_helper` defines the following functions:
+
+.. function:: test.support.script_helper._assert_python(expected_success, *args, **env_vars)
+
+   Execute the interpreter in a subprocess
+
+.. function:: test.support.script_helper.assert_python_ok(*args, **env_vars)
+   
+   Assert that running the interpreter with `args` and optional environment
+   variables `env_vars` succeeds (rc == 0) and return a (return code, stdout,
+   stderr) tuple.
+   
+   If the __cleanenv keyword is set, env_vars is used a fresh environment.
+    
+   Python is started in isolated mode (command line option -I),
+   except if the __isolated keyword is set to False.
+
+.. function:: test.support.script_helper.assert_python_failure(*args, **env_vars)
+
+   Assert that running the interpreter with `args` and optional environment
+   variables `env_vars` fails (rc != 0) and return a (return code, stdout,
+   stderr) tuple.
+
+.. function:: test.support.script_helper.spawn_python(*args, **kw)
+
+   Run a Python subprocess with the given arguments.
+
+.. function:: test.support.script_helper.kill_python(p)
+
+   Run the given Popen process until completion and return stdout.
+
+.. function:: test.support.script_helper.make_script(script_dir, script_basename, source)
+
+   Create a new script based on the given parameters.
+
+.. function:: test.support.script_helper.make_zip_script(zip_dir, zip_basename, script_name, name_in_zip=None)
+
+   Create a new zipped script, based on the given parameters.
+
+.. function:: test.support.script_helper.make_pkg(pkg_dir, init_source='')
+
+   Create a new Python package, based on given paratemeters.
+
+.. function:: test.support.script_helper.make_zip_pkg(zip_dir, zip_basename, pkg_name, script_basename, source, depth=1, compiled=False)
+
+   Create a new zipped package, based on given parameters.
