Butler - bjb@mojatatu.com + +ADDING PLUGINS +-------------- + +A new plugin should be written in python as a class that inherits from TdcPlugin. +There are some examples in plugin-lib. + +The plugin can be used to add functionality to the test framework, +such as: + +- adding commands to be run before and/or after the test suite +- adding commands to be run before and/or after the test cases +- adding commands to be run before and/or after the execute phase of the test cases +- ability to alter the command to be run in any phase: + pre (the pre-suite stage) + prepare + execute + verify + teardown + post (the post-suite stage) +- ability to add to the command line args, and use them at run time + + +The functions in the class should follow the following interfaces: + + def __init__(self) + def pre_suite(self, testcount, testidlist) # see "PRE_SUITE" below + def post_suite(self, ordinal) # see "SKIPPING" below + def pre_case(self, test_ordinal, testid) # see "PRE_CASE" below + def post_case(self) + def pre_execute(self) + def post_execute(self) + def adjust_command(self, stage, command) # see "ADJUST" below + def add_args(self, parser) # see "ADD_ARGS" below + def check_args(self, args, remaining) # see "CHECK_ARGS" below + + +PRE_SUITE + +This method takes a testcount (number of tests to be run) and +testidlist (array of test ids for tests that will be run). This is +useful for various things, including when an exception occurs and the +rest of the tests must be skipped. The info is stored in the object, +and the post_suite method can refer to it when dumping the "skipped" +TAP output. The tdc.py script will do that for the test suite as +defined in the test case, but if the plugin is being used to run extra +tests on each test (eg, check for memory leaks on associated +co-processes) then that other tap output can be generated in the +post-suite method using this info passed in to the pre_suite method. + + +SKIPPING + +The post_suite method will receive the ordinal number of the last +test to be attempted. It can use this info when outputting +the TAP output for the extra test cases. + + +PRE_CASE + +The pre_case method will receive the ordinal number of the test +and the test id. Useful for outputing the extra test results. + + +ADJUST + +The adjust_command method receives a string representing +the execution stage and a string which is the actual command to be +executed. The plugin can adjust the command, based on the stage of +execution. + +The stages are represented by the following strings: + + 'pre' + 'setup' + 'command' + 'verify' + 'teardown' + 'post' + +The adjust_command method must return the adjusted command so tdc +can use it. + + +ADD_ARGS + +The add_args method receives the argparser object and can add +arguments to it. Care should be taken that the new arguments do not +conflict with any from tdc.py or from other plugins that will be used +concurrently. + +The add_args method should return the argparser object. + + +CHECK_ARGS + +The check_args method is so that the plugin can do validation on +the args, if needed. If there is a problem, and Exception should +be raised, with a string that explains the problem. + +eg: raise Exception('plugin xxx, arg -y is wrong, fix it') |
