3 """Automated tests of the apt-p2p functionality.
5 This script runs several automatic tests of some of the functionality in
8 @type tests: C{dictionary}
9 @var tests: all of the tests that can be run.
10 The keys are the test names (strings) which are used on the command-line
11 to identify the tests (can not be 'all' or 'help'). The values are tuples
12 with four elements: a description of the test (C{string}), the bootstrap
13 nodes to start (C{dictionary}), the downloaders to start (C{dictionary},
14 and the apt-get commands to run (C{list}).
16 The bootstrap nodes keys are integers, which must be in the range 1-9.
17 The values are the dictionary of keyword options to pass to the function
18 that starts the bootstrap node (see L{start_bootstrap} below).
20 The downloaders keys are also integers in the range 1-99. The values are
21 the dictionary of keyword options to pass to the function
22 that starts the downloader node (see L{start_downloader} below).
24 The apt-get commands' list elements are tuples with 2 elements: the
25 downloader to run the command on, and the list of command-line
26 arguments to specify to the apt-get program.
29 @var CWD: the working directory the script was run from
