SpeedTests

SpeedTests is a (slightly misnamed) framework for cross-browser comparisons. See the wiki page for details about the project.

This document will only concern the installation of the framework.

Requirements

The client has no strict requirements other than Python 2.5+. Highly suggested is the [jwt module] (https://github.com/markrcote/jwt) if you need to validate results with the server.

The server requires [templeton] (https://github.com/markrcote/templeton), which in turn requires [web.py] (http://webpy.org/). The server also optionally supports jwt.

Installation

Server

The server is made of two components: a tests server and a results server. The former serves the tests to the client. By not bundling the tests with the clients, it is easy to add new tests. The latter accepts results from the clients and provides a simple web UI to view them. They can be combined into a single server or separated onto two machines. Furthermore, a server can be configured to proxy results onto another results server.

The server is configured by the file speedtests_server.conf, which should be placed into the server directory (speedtests/server/).

The [speedtests] section can contain the following options:

  • html_dir: For serving tests, this is the location of the tests' html directory. It defaults to ../html/.
  • proxy: Indicates that results should be proxied onto the given server and not stored locally. Defaults to None (no proxying).
  • db_host: Hostname of the server storing the results database. Defaults to localhost.
  • db_name: Name of the results database. Defaults to "speedtests".
  • db_user: Username to access the results database. Defaults to "speedtests".
  • db_passwd: Password to access the results database. Defaults to "speedtests".

Database table name is not configurable, since one table is used per test and is named according to the test. You should create these tables on the results server by loading the SQL files found in speedtests/server/speedtests/*/ (FIXME: automate this!)

The [clients] section, which must be present on a results server, should list all clients in the form = . This is used for the "Machine" drop down on the results web UI.

The [client keys] section should contain options in the form = . This is used to authenticate clients' requests. The jwt module is required if this section exists and has entries.

There is no strict separation of the functionality of the tests and results server; rather, if tests exist in the html directory, they are served as requested. Similarly, if the results db exists, the server will attempt to store results if sent and serve results if requested.

To run a development version of the server, cd into the server directory and run "python server.py [port]", where port is optional and defaults to 8080. The tests' static HTML files (if they exist) will be served as http://0.0.0.0:8080/. The results are available at http://0.0.0.0:8080/results.html. The dynamic API (tests list, results server) is served under http://0.0.0.0:8080/api/. See the "urls" tuple in server/handlers.py for the available APIs.

For production, a real web server, such as nginx, should be configured to serve the html directory at a particular path (e.g. /speedtests/) and speedtests_server.fcgi served under that path as api/ (e.g. /speedtests/api/).

Clients

The main client program is client/speedtests.py. It is configured with the file speedtests.conf, which should be placed into the client/ directory.

The main settings in speedtests.conf are in the [speedtests] section:

  • 64bit: Instructs the Nightly downloader to grab the 64-bit version.
  • local_port: The port the local server should run under. Defaults to 8111.
  • test_base_url: The URL of the static test files on the tests server.
  • server_url: The URL of the tests server web API (for getting the list of available tests).
  • server_results_url: The URL of the results server web API (for submitting results).

Optionally, the config file may also contain a section for the current OS ("osx", "linux", or "windows"), which in turn can contain an option for any or all browsers ("firefox", "safari", "internet explorer", "opera"). The option value is the path to that browser's main executable. This can be used if one or more browsers are installed to nonstandard locations. There is no "nightly" option because Nightly is always downloaded freshly.

Without any options, the client will attempt to run all browsers (Firefox, Opera, IE, Safari, Chrome) that it finds. It will also attempt to download the latest Nightly.

You can also provide a list of browser names, and only those will be executed (using the same strings as in the config file described above). You can also provide the -t or --test option one or more times to list the only tests that should be run. Note that in this case the client does not get a list of tests from the server, so the relative URL to the main test page should be given (e.g. -t csstest/index.html -t jstest/index.html ...).

Giving the -n or --noresults option indicates that the results should not be sent to the server. They will still be printed to the console.

The --testmode option can be used to test a browser's settings using a no-op test. No results are sent (i.e. -n is implied).

The -s or --sign option can be given with a path to a file containing a key that will be used to sign the results via JSON Web Signature. The server must have the same key defined in its config file with the client's IP address (see above), or the results will be discarded. The jwt module is required for this option.

Configuring client browsers

If present, before executing each test, the client copies the appropriate stored profile over top of the browser's current profile. No profiles are packaged with speedtests, so the browsers must be configured properly and their profiles stored before automated runs can be started.

All browsers must be able to (a) open pages on localhost and (b) open pop-ups, at least from localhost. Additionally, the cache and history should be empty.

The pop-ups setting is necessary because the client opens all tests in a new window of a set size.

It is suggested that each browser be opened manually and the necessary settings applied. Then the special command "archive" can be given, e.g. "python speedtests.py archive opera" to store Opera's current profile. After this, the stored profile will be used each time, ensuring that the browser's configuration is always the same. The --testmode option can be given to verify that the browser is configured properly without having to execute a test.
