To allow developers to run the testsuite +easily, the environment does not require root privilege (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 beginning 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 +beginning 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.
