This page hasn't finished yet.
Your feedback to firstname.lastname@example.org would be greatly appreciated.
Your contribution is a big step to us! You may reference this page. I will brief out something here since that page is having some similiar topics as this MDN document.
You can find related programming guide for marionette. This shows the basic layout and how you would write a test on gaia-ui-tests. Also, you will find we strictly go accord to PEP8 style except the 80 characters, E501. However, we do want to keep it within 100 charaters or so. If you are using Ubuntu, you can install a basic check program for PEP8 by doing:
apt-get install pep8
and, then you can check your program style by doing this command:
pep8 --ignore=E501 <your test file location and name>
After you finished writing the test(s), you can send a pull request to the branch in Mozilla! We sometime also open issues in github of Mozilla/gaia-ui-tests to dicuss in advance. In that case, we can understand if our contribution was finished, if there are better suggestion, and if this contribution worth a million!

At this point of time, we change codes dramatically everyday. We will try to come out a real gaia-ui-test mthods overview soon. Before that comes into reality, you may take marionette methods page for reference. Furthermore, please do notice that marionette methods page has some out-of-date stuffs, too. Please kindly help us to correct them if possible.
Another few good reference is to dig into the code to know the common libraries we are using in gaia UI tests. I suggests that you can start with gaia_test.py. Moreover, you can look into gaia_data_layer.js and gaia_apps.js. Also, all the files under apps/ folder are other good-to-know stuffs.
TODO: Gaia-UI-Tests functions/methods/attributes reference
Everytime when you have no idea to start with in Gaia-UI-Tests, you can write so and run it.
# This Source Code Form is subject to the terms of the Mozilla Public # License, v. 2.0.

You will find yourself in a console after running this. You can send single line code and it would return the result and control the device/emulator immediately. However, please do understand there are some variable restriction in this case. There are some reserved words in pdb that you can't use. Here is the reference of pdb from official Python website.
When you tried to debug in your program, you may just put import pdb; pdb.set_trace() before the line it crashed to help you better debug it.
Also, you can read the gaia(html) from B2G project to better helping you with realizing the code. But, here is another way to get the realtime code. You may send import re; import codecs; f = codecs.open("temp","w","utf8"); f.write(re.sub(r'<(script).*?</\1>(?s)', r'', self.marionette.page_source)) in pdb, and it should write the current code without localization stuffs to a file named "temp".
CSS and XPath Locators
When we are trying to get locators of web elements, the most simple ways to do so is by linktext, id, or name. However, we do need to get webelement that sit in complex structure of HTML without linktext, id, or name. There are two main ways to find web elements in this case - CSS selector or XPath selector.
You can find basic XPath reference in w3schools, CSS selectors reference in w3schools, or CSS selectors reference in W3C standard. I don't want to get into this too deep. You will find it easy to pick up knowledge from others' test scripts.
Note: CSS selector is preferrable over XPath selector, the reason is css selectors is usually faster. (external link for explanation)
You can also find this cheatsheet easy to use or keep you away from chaos.
You will find manifest.ini files under all folders inside tests folder. It's the manifest files we are talking about. Inside the manifest files, we can find that it might indicate the required status when running tests under this folder, it might include test files needed, and it might include the other manifest files to be read.
Here is a list of the types used, and when to use them:
- b2g - this means the test is a B2G (Firefox OS) test. All tests must include this type.
- antenna - these tests require an antenna (headphones) to be connected.
- bluetooth - requires bluetooth to be available.
- camera - these tests require use of a camera.
- carrier - an active SIM card with carrier connection is required.
- lan - a local area connection (not cell data) is required by these tests (see note below).
- offline - specifically requires no online connection.
- online - some sort of online connection (lan or carrier) is required.
- qemu - these tests require the Firefox OS emulator to run.
- sdcard - a storage device must be present.
- wifi - this means a WiFi connection is required.
- xfail - a special type that indicates the test is expected to fail.
Note: Please do read the Mozilla/gaia-ui-tests github readme for most up-to-date types and help us to update in this page.
