Hi all, The preview mail is blocked due to the attachment is too large. I pasted it to mail content below. I have finished my first version of Proposal about the GSOC2013 idea: Automatic testing. Can some help me have a review? thanks Automated Testing Adam Short description: PMA is a popular web based database management tool. It usually undergoes new releases, bug fixes, new feature development and refactoring. Since the PMA production code is changed frequently and our code is finished by developers from all over the world, in order to guarantee the production quality, it is very necessary to run Unit testing on Jenkins (Hudson). Unit Tests have several benefits to us. It allows us changing code quickly under full testing. By running unit tests, a developer can identify whether his latest changes to the code base has broken anything. Unit Tests can also help new developers really understand the design of the code and it can give our developers visual feedback about which lines are covered. From PMA CI Page, Currently, the code coverage of PMA is 48%. More code coverage means more guarantee to production. Goal: 1. Increase the code coverage to a reasonable percentage (80%) 2. Set up the necessary scripts to automate this. 3. Help other developers to set up their unit test cases. 4. Functional test case to cover render issue Location · Country : China · Time Zone : GMT +8:00 Education Postgraduate student, institute of Software, Beijing University of Aeronautics and Astronautics, China Email / IRC / Jabber · adamgsoc2013(a)gmail.com Synopsis Since the PMA production code is changed frequently and our code is finished by developers from all over the world, in order to guarantee the production quality, it is very necessary to run Unit testing on Jenkins (Hudson). Unit Tests have several benefits to us. It allows us changing code quickly under full testing. By running unit tests, a developer can identify whether his latest changes to the code base has broken anything. Unit Tests can also help new developers really understand the design of the code and it can give our developers visual feedback about which lines are covered. From PMA CI Page, Currently, the code coverage of PMA is 48%. More code coverage means more guarantee to production. About this idea, at least two things should be done: 1. Create more test cases to increase the code-coverage of the test-suite 2. Set up necessary scripts to automate this. My goal of this project is to increase the code coverage to a reasonable percentage (80%) and help other developers to set up their unit test cases. Besides the two things above, for the display logic code, we can cover them using Functional test case. In other word, we can use selenium to check Page element is loaded correctly, I think this work is as important as Unit test. I will coverage Functional test when I finish Unit testing target. Benefit of Functional testing, we can guarantee phpmyadmin can work well on GradeA browsers. 1. Check the page is loaded correctly 2. Check the page is working well o GradeA browsers. 3. Check the css/js is working well Benefits to the users With the automatic testing, developers can make changes quickly and provide users a more stable and fully tested version of phpMyAdmin. Benefits to developers: It helps developers to verify that the code changes are working fine. Unit Tests can also help new developers really understand the design of the code and it can give our developers visual feedback about which lines are covered. Users will always get upon each and every change developers can run the test suite and verify that the changes are safe to commit. By running the selenium test cases it can be verified that the basic functionalities are working fine in PMA. Since a large amount of re-factoring is going on, and it is very helpful if automated testing is available to make sure nothing will break while re-factoring. Project Details ================ 1. Automatic Process=================== I am very familiar with the CI environment and PHP code coverage, because I succeeded to finishing a similar project when I was an Intern on Yahoo! last year. I finished an automatic testing job: 1. Finish PHP UNIT code and Functional testing code. 2. Commit to GIT will trigger a CI build. 3. The CI build is done by: selenium + Firefox+ Xvfb (so that we don’t need display) 4. Output the code coverage report. ================ 2. Code Learning =================== I have more thoughts on the Phpmyadmin Automatic testing after reading more codes. In the index.php page, PMA will display all the links for users. The links can be some types: 1. for server operation: server_<operation>.php (ig: server_databases.php) 2. for database operation: db_<operation>.php (ig: db_events.php ) 3. for table operation: tbl_<operation>..php (ig: tbl_replace.php ) ................. Workflow: Take "server_databases.php" for example. It is used to create or drop database. In the server_databases.php, the file will include: 1. "server_databases.js" in JS folder, it is for Ajax request to backend. 2. "display_create_database.lib.php" it is output the page element for create table, including action tag for Ajax request. 3. When an user clicks the "create", there will be a Ajax request to db_create.php 4. In db_create.php, the SQL is executed and return the execution results to frontend. 5. The frontend page uses the Ajax request and refreshes the page. That is the simple process for every user operation. ================ 3. Unit testing=================== From our code view: 1. ROOT folder: there are files about the display and links In the index.php page, PMA will display all the links for users. The links can be some types: · 1. for server operation: server_<operation>.php (ig: server_databases.php) · 2. for database operation: db_<operation>.php (ig: db_events.php ) · 3. for table operation: tbl_<operation>..php (ig: tbl_replace.php ) These files are not covered by Unit test, so we can use Selenium with Page element checking to cover them (Functional case). In other word, we can use selenium to check if Page element is loaded correctly, I think this work is as important as Unit test. Other benefits, we can cover phpmyadmin can work well with GradeA browsers. · check the page is loaded correctly · check the page is working well with GradeA browsers. · check the css/js is working well 2. For the Library folder, there is backend logic, it is suitable to use UNIT test to cover. · Create more test cases to increase the code-coverage of the test-suite · Set up necessary scripts to automate this. Automate building process, running unit tests; generate code coverage and analysis using Jenkins Deliverables · Unit testing code coverage grows to a reasonable percentage: 80% · With selenium testing scripts, help more developers setup their Unit test case. · Functional test case · Increase some regression testing cases. Time About 40 hours per week. Bio I am Adam. Currently I am a student of Institute of Software, Beijing University of Aeronautics and Astronautics, China.
