Testing in Firefox- Mochitest!

You’ve just written a feature or  changed a large number of file including javascript- hopefully! you want to test it.  So I am back this week with a testing tool that Firefox use for testing 🙂   I will try my hard to explain my experience 😛

Mochitest

Mochitest is an automated testing framework built on top of the MochiKit JavaScript libraries. It’s just one of the automated regression testing frameworks used by Mozilla. Tests report success or failure to the test harness using JavaScript function calls.

Mochitest’s use JavaScript function calls to communicate test success or failure that can make it unsuitable for certain types of test. Only things that can in some way be tested using JavaScript (with chrome privileges!) can be tested with this framework. Firefox use a little part of Selenium  testing tool.

How to Run Mochitest

So as we always do- Run  ./mach build  after your changes.

The Mozilla build machines run Mochitest as part of the build and test process, so we get to know pretty quickly if someone commits a change to the source code that breaks something. However,you still run Mochitest yourself before you commit any risky new code. You don’t want to be the one who wastes everyone’s time by breaking the tree   😛

For Running Mochitest:

./mach mochitest

Run the above command after your build is completed and wait till the completion of tests. Avoid using Keyboard and mouse while running Mochitest. I will update the blog with a screenshot ASAP. As I don’t have any screenshot yet.

I am in my Computer lab- there is no professor around!  so I thought- why not I use this  time to write a  blog 😀

It been so long I haven’t wrote anything about my work. Currently, I am working on Few Reader mode bugs.  I will write about this in my next blog. Stay tuned  🙂
