pyral 0.9.2

Python toolkit for Rally REST API

Latest Version: 0.9.4

The pyral package enables you to push, pull and otherwise wrangle the data in your Rally subscription using the popular and productive Python language. The pyral package provides a smooth and easy to use veneer on top of the Rally REST Web Services API using the JSON flavored variant.

Getting started

Rally has created a Python package that you can quickly leverage to interact with the data in your subscription via the REST web services API. You can create, read, update, and delete the common artifacts and other entities via the Python toolkit for Rally.

Download

Files are available at the download page .

The git repository is available at http://github.com/Rallydev/pyral

Installation

Obtain the requests package and install it according to that package's directions.

Unpack the pyral distribution file (zip or tar.gz) and then install the pyral package.

python setup.py install

Use whatever setup options you need for your particular Python environment.

Sanity Check

Fire up a command line Python interpreter. Attempt to import the relevant packages.

$ python
Python 2.6.5 [other Python interpreter info elided ...]
>> import requests
>> import pyral
>> pyral.__version__
(0, 9, 2)

30 second highlight

Since Python is a very flexible and extensible language, we were able to make access to the object model extremely simple. For example, if you have a a UserStory instance returned by a pyral operation assigned to the name story, the following code iterates over the tasks.

for task in story.Tasks:
   print task.Name

There is no need to make a separate call to fetch all the tasks for the story. When you follow domain model attributes in the Python code, the Python toolkit for Rally REST API machinery automatically loads in the necessary objects for you.

Full Documentation

The complete documentation for the Python toolkit for Rally REST API is in the doc/build/html subdirectory in the repository. The rendered version of this is also available at http://readthedocs.org/docs/pyral.

Sample code

Common setup code

import sys
from pyral import Rally, rallySettings
options = [arg for arg in sys.argv[1:] if arg.startswith('--')]
args    = [arg for arg in sys.argv[1:] if arg not in options]
server, user, password, workspace, project = rallySettings(options)
rally = Rally(server, user, password, workspace=workspace, project=project)
rally.enableLogging('mypyral.log')
Show a TestCase identified by the FormattedID value.
Copy the above boilerplate and the following code fragment and save it in a file named gettc.py
query_criteria = 'FormattedID = "%s"' % args[0]
response = rally.get('TestCase', fetch=True, query=query_criteria)
if response.errors:
    sys.stdout.write("\n".join(errors))
    sys.exit(1)
for testCase in response:  # there should only be one qualifying TestCase
    print "%s %s %s %s" % (testCase.Name, testCase.Type,
                           testCase.DefectStatus, testCase.LastVerdict)
  • Run it by providing the FormattedID value of your targeted TestCase as a command line argument

    python gettc.py TC1184

Get a list of workspaces and projects for your subscription
Copy the above boilerplate and the following code fragment and save it in a file called wksprj.py
workspaces = rally.getWorkspaces()
for wksp in workspaces:
    print "%s %s" % (wksp.oid, wksp.Name)
    projects = rally.getProjects(workspace=wksp.Name)
    for proj in projects:
        print "    %12.12s  %s" % (proj.oid, proj.Name)
  • Run the script

    python wksprj.py

Get a list of all users in a specific workspace
Copy the above boilerplate and the following code fragment and save it in a file called allusers.py
all_users = rally.getAllUsers()
    for user in all_users:
        tz   = user.UserProfile.TimeZone or 'default'
        role = user.Role or '-No Role-'
        values = (int(user.oid), user.Name, user.UserName, role, tz)
        print("%12.12d %-24.24s %-30.30s %-12.12s" % values)
  • Run the script

    python allusers.py --rallyWorkspace="Product Engineering"

Create a new Defect
Copy the above boilerplate and the following code fragment and save it in a file called crdefect.py
proj = rally.getProject()

# get the first (and hopefully only) user whose DisplayName is 'Sally Submitter'
user = rally.getUserInfo(name='Sally Submitter').pop(0)

defect_data = { "Project" : proj.ref, "SubmittedBy" : user.ref,
                "Name" : name, "Severity" : severity, "Priority" : priority,
                "State" : "Open", "ScheduleState" : "Defined",
                "Description" : description }
try:
    defect = rally.create('Defect', defect_data)
except Exception, details:
    sys.stderr.write('ERROR: %s \n' % details)
    sys.exit(1)
print "Defect created, ObjectID: %s  FormattedID: %s" % (defect.oid, defect.FormattedID)
  • Run the script

    python crdefect.py <Name> <severity> <priority> <description>

    making sure to provide valid severity and priority values for your workspace

Update an existing Defect
Copy the above boilerplate and the following code fragment and save it in a file called updefect.py .
 defectID, customer, target_date, notes = args[:4]
 # target_date must be in ISO-8601 format "YYYY-MM-DDThh:mm:ssZ"

 defect_data = { "FormattedID" : defectID,
                 "Customer"    : customer,
                 "TargetDate"  : target_date,
                 "Notes"       : notes
               }
try:
    defect = rally.update('Defect', defect_data)
except Exception, details:
    sys.stderr.write('ERROR: %s \n' % details)
    sys.exit(1)

print "Defect %s updated" % defect.FormattedID
  • Run the script

    python updefect.py <Defect FormattedID> <customer> <target_date> <notes text...>

Config Options

The pyral package uses a priority chain of files, environment variables and command line arguments to set the configuration context when an instance of the Rally class is created. See the complete documentation for detailed information on this mechanism. Here's a brief description of how you can specify a configuration when you create an instance of the Rally class.

Configuration file settings

Config file item Description
SERVER Rally server (example rally1.rallydev.com)
USER Rally subscription UserName value
PASSWORD password for the Rally subscription UserName
WORKSPACE Rally Workspace
PROJECT Rally Project
VERSION Rally REST Web Services API version

The item names in config files are case sensitive.

Command line options

Command line option Description
--rallyConfig=<config_file_name> name of the file with settings for pyral
--config=<config_file_name> ditto
--conf=<config_file_name> ditto
--cfg=<config_file_name> ditto
--rallyUser=<foo> your Rally UserName
--rallyPassword=<bar> password associated with the Rally UserName
--rallyWorkspace=<bar> Workspace in Rally you want to interact with
--rallyProject=<bar> Project in Rally you want to interact with
--rallyVersion=<bar> Rally REST Web Services API version

Prerequisites

  • Python 2.6 or 2.7
  • The requests package, 0.8.2 or better Developed using requests 0.9.3. There are reports where requests > 0.9.3 resulted in connection problems (as in not being able to connect) that may be related to SSL. You should be able to use the verify_ssl_cert keyword argument when obtaining a pyral Rally instance to overcome this issue. If you are using requests >- 0.9.3, you must also have certifi-0.0.8 (available on PyPI)

Versions

  • 0.9.2 -

    Fixed getProject to take optional project name argument. Added HTTP header item in config.py to set Content-TYpe to 'application/json'. Added recognition of verify_ssl_cert=True/False as keyword argment to Rally constructor. Explicit specification results in passing a verify=True/False to the underlying requests package. This can be useful when dealing with an expired SSL certificate. Upped default WSAPI version in config.py to 1.37 to support dyna-types (specifically PortfolioItem and sub-types).. Modified addAttachment to conform with non-backward compatible change in Rally WSAPI involving how an attachment is related to an artifact. Fixed defect in calculating an Attachment file size (use pre-encoded rather than post-encoded size).

    This release is intended as the final beta before a 1.0 release.

  • 0.9.1 -

    Upped default WSAPI version in config.py to 1.30 All entities that are subclasses of WorkspaceDomainObject now have a details method that show the attribute values in an easy to read multiline format. Dropped attempted discrimination of server value to determine if it is a name or an IPv4 address No longer look for http_proxy in environment, only https_proxy. Introduced convenience methods dealing with attachments. Corrected resource URL construction for the major ops (GET, PUT, POST, DEL) when project=None specified (useful for Workspace spanning activities).

  • 0.8.12 - Fixed premature exercise of iterator in initial response

  • 0.8.11 -

    Fixed inappropriate error message when initial connect attempt timed out. Message had stated that the target server did not speak the Rally WSAPI. Improved context handling with respect to workspace and project settings.

  • 0.8.10 -

    Attempted to bolster proxy handling. Limited success as there is an outstanding issue in equests (urllib3) not implementing CONNECT for https over http.

  • 0.8.9 - initial attempt at providing proxy support

  • 0.8.8 - added warn=True/False to Rally instantiation

  • 0.8.7 - Initial release on developer.rallydev.com

TODO

  • Python 3.3 + support
  • Expand the documentation
  • Expand the repertoire of example scripts
  • Refactor the source code to make use decorators in pyral.restapi, dynamically construct the Rally schema hierarchy economically.
  • Monitor requests/urllib3 for release that fully supports HTTPS over HTTP proxy.
