MailNews:Automated Testing

Please do not edit this page unless you are on the Thunderbird or SeaMonkey MailNews team. Your feedback and comments are welcomed on the discussion page.

Automated testing for MailNews (i.e. Thunderbird and the Mail/Newsgroups part of SeaMonkey) is becoming more important. We need to ensure that when we are fixing bugs we do not introduce regressions in other areas of the code. Automated testing is a vital part of this.

This page and its sub-pages are intended to describe and provide pointers to the available test mechanisms within MailNews and supporting information for developers and testers.

Developers and contributors should consider adding tests within MailNews where possible.

Tests are not only useful for checking for regressions, but they can help developing and testing of patches. For example, xpcshell tests are very good at checking interfaces, and are very quick to run as they only require a "make check" - you don't have to start up the application, and all the tests happen automatically in a consistent manner.

General Notes

The devmo pages have some good descriptions on how to start writing automated tests.

Not all the automated tests will work at the moment, some of them require new support architectures, some of them require other issues fixing before they will pass/work correctly.

Automated Tests

• MailNews:xpcshell tests
  • These currently run on the SeaMonkey tinderboxes, and report as TUnit. Thunderbird hopes to pick running of these up soon (bug 422817).
