git-remote-mediawiki: test environment of git-remote-mediawiki
In order to test git-remote-mediawiki, a set of functions is needed to manage a MediaWiki: edit a page, remove a page, fetch a page, fetch all pages on a given wiki. A few helper function are also provided to check the content of directories. In addition, this patch provides Makefiles to execute tests. See the README file for more details.

+Tests for Mediawiki-to-Git
+==========================
+
+Introduction
+------------
+This manual describes how to install the git-remote-mediawiki test
+environment on a machine with git installed on it.
+
+Prerequisite
+------------
+
+In order to run this test environment correctly, you will need to
+install the following packages (Debian/Ubuntu names, may need to be
+adapted for another distribution):
+
+* lighttpd
+* php5
+* php5-cgi
+* php5-cli
+* php5-curl
+* php5-sqlite
+
+Principles and Technical Choices
+--------------------------------
+
+The test environment makes it easy to install and manipulate one or
+several MediaWiki instances. To allow developers to run the testsuite
+easily, the environment does not require root priviledge (except to
+install the required packages if needed). It starts a webserver
+instance on the user's account (using lighttpd greatly helps for
+that), and does not need a separate database daemon (thanks to the use
+of sqlite).
+
+Run the test environment
+------------------------
+
+Install a new wiki
+~~~~~~~~~~~~~~~~~~
+
+Once you have all the prerequisite, you need to install a MediaWiki
+instance on your machine. If you already have one, it is still
+strongly recommended to install one with the script provided. Here's
+how to work it:
+
+a. change directory to contrib/mw-to-git/t/
+b. if needed, edit test.config to choose your installation parameters
+c. run `./install-wiki.sh install`
+d. check on your favourite web browser if your wiki is correctly
+ installed.
+
+Remove an existing wiki
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Edit the file test.config to fit the wiki you want to delete, and then
+execute the command `./install-wiki.sh delete` from the
+contrib/mw-to-git/t directory.
+
+Run the existing tests
+~~~~~~~~~~~~~~~~~~~~~~
+
+The provided tests are currently in the `contrib/mw-to-git/t` directory.
+The files are all the t936[0-9]-*.sh shell scripts.
+
+a. Run all tests:
+To do so, run "make test" from the contrib/mw-to-git/ directory.
+
+b. Run a specific test:
+To run a given test <test_name>, run ./<test_name> from the
+contrib/mw-to-git/t directory.
+
+How to create new tests
+-----------------------
+
+Available functions
+~~~~~~~~~~~~~~~~~~~
+
+The test environment of git-remote-mediawiki provides some functions
+useful to test its behaviour. for more details about the functions'
+parameters, please refer to the `test-gitmw-lib.sh` and
+`test-gitmw.pl` files.
+
+** `test_check_wiki_precond`:
+Check if the tests must be skipped or not. Please use this function
+at the beggining of each new test file.
+
+** `wiki_getpage`:
+Fetch a given page from the wiki and puts its content in the
+directory in parameter.
+
+** `wiki_delete_page`:
+Delete a given page from the wiki.
+
+** `wiki_edit_page`:
+Create or modify a given page in the wiki. You can specify several
+parameters like a summary for the page edition, or add the page to a
+given category.
+See test-gitmw.pl for more details.
+
+** `wiki_getallpage`:
+Fetch all pages from the wiki into a given directory. The directory
+is created if it does not exists.
+
+** `test_diff_directories`:
+Compare the content of two directories. The content must be the same.
+Use this function to compare the content of a git directory and a wiki
+one created by wiki_getallpage.
+
+** `test_contains_N_files`:
+Check if the given directory contains a given number of file.
+
+** `wiki_page_exists`:
+Tests if a given page exists on the wiki.
+
+** `wiki_reset`:
+Reset the wiki, i.e. flush the database. Use this function at the
+begining of each new test, except if the test re-uses the same wiki
+(and history) as the previous test.
+
+How to write a new test
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Please, follow the standards given by git. See git/t/README.
+New file should be named as t936[0-9]-*.sh.
+Be sure to reset your wiki regulary with the function `wiki_reset`.
