The test suite is organized in a hierarchy +with {mnesia_SUITE, all} as the top. + +The module called mt, implements various convenience functions +to ease up the execution of test cases. It does also provide +aliases for some test cases. For example the atom Mod is an +alias for {Mod, all}, the atom all for {mnesia_SUITE, all}, +evil for mnesia_evil_coverage_test etc. + + mt:struct(TestCase) + + Displays the test case structure from TestCase + and downwards the hierarchy. E.g. mt:struct(all) + will display the entire test suite. + + mt:t(TestCase), mt:t(TestCase, Config) + + Runs a single test case or a hierarchy of test cases. + mt:t(silly) is be a good starter, but you may also + try mt:t(all) directly if you feel lucky. + + The identity of the last run test case and the outcome of + it is stored on file. mt:t() will re-run the last test case. + + The Config argument contains various configuration + parameters for the test cases, such as which nodes that + are available for running the test suite. The default + settings should be enough for the most. Use mt:read_config() + to get the current default setting and change it with + mt:write_config(Config). + + mt:doc(TestCase) + + Generates html documentation for the test suite. + +In order to be able to run the test suite, the Erlang node must +be started with the distribution enabled and the code path must +be set to the mnesia/ebin, mnesia/examples, and mnesia/test +directories. E.g. the following would do: + + erl -sname a -pa $top/examples -pa $top/src -pa $top/ebin + +where $top is the path to the Mnesia installation. Many test +cases needs 2 or 3 nodes. The node names may explicitly be +stated as test suite configuration parameters, but by default +the extra node names are generated. In this example the names +will be: a, a1 and a2. It is enough to start the first node +manually, the extra nodes will automatically be started if +neccessary. + +The attached UNIX shell script mt, does not work on all +platforms, but it may be used as a source for inspiration. It +starts three Erlang nodes in one xterm's each. The main xterm +(a@localhost) logs all output in the Erlang shell to a +file. The file is piped thru grep to easily find successful +test cases (i.e. test cases that encountered an error). + +During development we want to be able to run the test cases +in the debugger. This demands a little bit of preparations: + + - Start the neccessary number of nodes (normally 3). + This may either be done by running the mt script or + by starting the main node and then invoke mt:start_nodes() + to start the extra nodes with slave. + + - Ensure that the nodes are connected. The easiest way to do + this is by invoking mt:ping(). + + - Load all files that needs to be interpreted. This is typically + all Mnesia files plus the test case. By invoking mnesia:ni() + and mnesia:ni([TestModule]) the neccessary modules will be + loaded on all CONNECTED nodes. + +The test case execution is supervised in order to ensure that no test +case exceeds its maximum time limit, which by default is 5 minutes. +When the limit is reached, the running test case gets aborted and the +test server runs the next test case in line. This behaviour is useful +when running the entire test suite during the night, but it is really +annoying during debugging. + + Use the "erl -mnesia_test_timeout" flag to disable the test case + time limit mechanism. + +Some mechanisms in Mnesia are almost impossible to test with a +white box technique. In order to be able to write predictable +test cases which tests the same thing every time it is run, +Mnesia has been instrumented with debug functions. These may be +controlled from a test program. For example to verify that the +commit protocols work it is essential that it is possible to +ensure that we are able to kill Mnesia in the most critical +situations. Normally Mnesia is compiled with the debug +functions disabled and this means that test cases which +requires this functionality will be skipped. The mnesia:ni(), +mentioned above, functions ensures that the interpreted code is +instrumented with Mnesia's debug functionality. The mnesia:nc() +functions compiles Mnesia with the debug setting enabled. + +Happy bug hunting! + + Hakan Mattsson <[email protected]> + + diff --git a/lib/mnesia/test/mnesia.spec

The Mnesia test suite is structured in a hierarchy. +%%% Each test case is implemented as an exported function with arity 1. +%%% Test case identifiers must have the following syntax: {Module, Function}. +%%% +%%% The driver of the test suite runs in two passes as follows: +%%% first the test case function is invoked with the atom 'suite' as +%%% single argument. The returned value is treated as a list of sub +%%% test cases. If the list of sub test cases is [] the test case +%%% function is invoked again, this time with a list of nodes as +%%% argument. If the list of sub test cases is not empty, the test +%%% case driver applies the algorithm recursively on each element +%%% in the list. +%%% +%%% All test cases are written in such a manner +%%% that they start to invoke ?acquire_nodes(X, Config) +%%% in order to prepare the test case execution. When that is +%%% done, the test machinery ensures that at least X number +%%% of nodes are connected to each other. If too few nodes was +%%% specified in the Config, the test case is skipped. If there +%%% was enough node names in the Config, X of them are selected +%%% and if some of them happens to be down they are restarted +%%% via the slave module. When all nodes are up and running a +%%% disk resident schema is created on all nodes and Mnesia is +%%% started a on all nodes. This means that all test cases may +%%% assume that Mnesia is up and running on all acquired nodes. +%%% +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +%%% +%%% doc(TestCases) +%%% +%%% Generates a test spec from parts of the test case structure +%%% +%%% struct(TestCases) +%%% +%%% Prints out the test case structure +%%% +%%% test(TestCases) +%%% +%%% Run parts of the test suite.

The benchmark uses a single, +%% simple update-intensive transaction to load the database system. +%% The single transaction type provides a simple, repeatable +%% unit of work, and is designed to exercise the basic components of +%% a database system. +%% +%% The definition of the TPC-B states lots of detailed rules and +%% conditions that must be fullfilled, e.g. how the ACID (atomicity, +%% consistency, isolation and durability) properties are verified, +%% how the random numbers must be distributed, minimum sizes of +%% the different types of records, minimum duration of the benchmark, +%% formulas to calculate prices (dollars per tps), disclosure issues +%% etc. Please, see http://www.tpc.org/ about the nitty gritty details. +%% +%% The TPC-B benchmark is stated in terms of a hypothetical bank. The +%% bank has one or more branches. Each branch has multiple tellers. The +%% bank has many customers, each with an account. The database represents +%% the cash position of each entity (branch, teller and account) and a +%% history of recent transactions run by the bank. The transaction +%% represents the work done when a customer makes a deposit or a +%% withdrawal against his account. The transaction is performed by a +%% teller at some branch. +%% +%% Each process that performs TPC-B transactions is called a driver. +%% Drivers generates teller_id, account_id and delta amount of +%% money randomly. An account, a teller and a branch are read, their +%% balances are adjusted and a history record is created. The driver +%% measures the time for 3 reads, 3 writes and 1 create. +%% +%% GETTING STARTED +%% +%% Generate tables and run with default configuration: +%% +%% mnesia_tpcb:start(). +%% +%% A little
