For instance, if you’re measuring your test coverage, a bug in RVS could cause a false-positive, indicating coverage where none exists. One of the key questions for bug triage and review is “Can this problem cause the RVS toolset to give erroneous results?” This is a very important consideration for a tool that is being used within the test process for safety-critical software. We also have automated tests from our Qualification Kit, which are in effect a system test of a similar size to the regression suite, and some specialized automation that exercises the GUI part of the RVS system. One part of our bug fixing process asks “Can we write an automated test that demonstrates the problem?” The five-thousand-odd command line tests we’ve built up over the years form a regression test suite that is run every time the continuous integration system builds the code, which helps us avoid reintroducing old problems.
This system also drives our regression testing. New issues are triaged for impact and likely time of fix, old issues are regularly reviewed, and every upcoming release has a collection of issues to be resolved attached to it.
HIDER 2 PROBLEMS SOFTWARE
This gives us a single place to hold the information that drives the software maintenance cycle.Ī system like this runs the risk of becoming a large black hole of unstructured information, so we make sure we stay on top of it. Not just the problems customers tell us about, but also bugs found by internal testing, ideas for new features and enhancements, discussions about significant design issues, everything. This can be used to hide decorative parts of a web page, such as icon fonts - that are not meant to be read by assistive technologies.Ī focusable element with aria-hidden="true" is ignored as part of the reading order, but still part of the focus order, making it’s state of visible or hidden unclear.So how do we handle all of this at Rapita? First, of course, we have our error reporting system where we record problems. The rule applies to any element with an aria-hidden="true" attribute.īy adding aria-hidden="true" to an element, content authors ensure that assistive technologies will ignore the element. Note: Using aria-hidden="false" on content that is a descendent of an element that is hidden using aria-hidden="true" will NOT expose that content to the accessibility API and it will not be accessible to screen readers or other assistive technologies. If aria-hidden is used to hide visible content from screen readers, the identical or equivalent meaning and functionality must be exposed to assistive technologies. Aria-hidden may be used with extreme caution to hide visibly rendered content from assistive technologies only if the act of hiding this content is intended to improve the experience for users of assistive technologies by removing redundant or extraneous content. Using the aria-hidden="true" attribute on an element removes the element and ALL of its child nodes from the accessibility API making it completely inaccessible to screen readers and other assistive technologies. The following examples FAIL the aria-hidden="true" elements do not contain focusable elements rule:įocusable form field, incorrectly disabled. Īria-hidden can’t be reset once set to true on an ancestor. Ĭontent made unfocusable through disabled. Some textĬontent made unfocusable through tabindex. The following examples PASS the aria-hidden="true" elements do not contain focusable elements rule:Ĭontent not focusable by default.
Use appropriate ARIA roles, states, and properties. Fix the issue by ensuring the value inside each attribute is spelled correctly and corresponds to a valid value.
