Yes, absolutely! A test which is passed by all current mainstream browsers is less helpful, less useful for all mainstream browser development teams than one that is failed by 1 or by a few of the most recent browser versions (e.g. Internet Explorer 11.0.13, Firefox 33, Opera 12.17, Safari 8.0, Chrome 38.0.2125.104, Konqueror 4.14.2) coming from the current mainstream browser manufacturers (Microsoft, Mozilla, Opera, Apple, Google, KDE). The number 1 purpose of the CSS2.1 test suite is to help achieve interoperable implementations of CSS 2.1 among web browsers and web-capable softwares. So, having tests which fail in the latest stable version of mainstream browsers is helpful and relevant. Failures in particular tests will inform the involved browser manufacturer development team about it.
There are many positive aspects to submitting tests which fail in recently released browser versions (e.g. Internet Explorer 11.0.13, Firefox 33, Opera 12.17, Safari 8.0, Chrome 38.0.2125.104, Konqueror 4.14.2). Still today, I would say that 50% of all questions asked in web authoring forum discussions newsgroups or in BBS are about browser incompatibilites (or suspected browser bugs) when rendering a particular webpage (markup and CSS) code.
3 types of tests.
padding-left: 20%; max-width: 10em;etc.
max-height: inherit; overflow: inherit;etc.
First, make sure your tests use valid markup code and use a XHTML 1.0 doctype declaration referencing to strict DTD. Then, make sure the pass and fail conditions of your tests are clear and easy to figure out. Then, contact me.
First, read carefully Contributing to the CSS Test Suites. Then upload your tests on an accessible website. Creating a webpage (an index.html page) that can act as a table of contents linking to your tests will be helpful. Then subscribe to the public- css-testsuite mailing list and announce that you have several tests to submit, to be reviewed and that you want to participate in the project.
When you have submitted at least 1 test that has been reviewed or that is considered as acceptable for CSS 2.1 test suite.
