Draft-template-image.png THIS PAGE IS A DRAFT Pencil-emoji U270F-gray.png
The page may be difficult to navigate, and some information on its subject might be lacking.
If you have any questions or ideas, please add them as a new topic on the discussion page.

Suites? Harnesses? Tests?

We all want quality to happen. How can we help? What is being run? What can I run something with? What does any of this mean? Not all questions are answered, but some.

This document has three sections:

  1. Test Harnesses - tools, designed to run tests. A harness may be targeted to a specific set of tests, or general to many kinds of tests. What test do you want to see run? Different harnesses could be used to run a given test. Which harness is better for which kinds of testing? kinds of testing?
  2. Test Suites - arbitrary groupings of test cases, roughly organized by functional area
  3. Test Infrastructure - the environments the test tools and test cases run in. This includes machine, operating system and physical location (ex: QA farm vs QA lab vs someone's desktop)

There are questions to be answered about any of our tests. If anyone has information or suggestions, please let us know.

  1. What tests do we have now, how current are they and how they should be run? Should they be expected to pass?
  2. What features or modules need tests to be written for them? What are the requirements of the testing that should happen?
  3. What tools do we have now that can be used to write tests? What tools outside of mozilla have people used to build tests and test tools?
  4. Of the tests currently in existence, which of them are outside the "mozilla.org" umbrella? Which use resources from outside? What is the reliability and accessibility of these resources? Are there issues which keep us from keeping local copies?

Any questions and suggestions are welcome!

Criteria for Colors

NOTE: that judgments are subjective and not "hard and fast". Caring enough to discuss will change a rating. Not caring enough to discuss is explanation enough.
  • Green: Generously defined now. Info is current or findable. Something is buildable and runnable by someone. There may still be obvious improvements needed.
  • Yellow: Little may be known. Probably not completely broken. Work to bring current is unknown.
  • Red: Obviously broken or missing. Info not findable. People not locatable.
