Auto Check (Components > Auto Check) validates the current page after every successful Selenese command. (That is not necessarily on every page reload - e.g. it may skip pages that redirect.) You can use some standard checks (with optional configuration) or create custom ones.
Negative checks validate that given selector(s) don’t match any elements on the page. That’s useful if your web server, framework or programming language report errors/warnings/notices in some kind of fixed format.
There is a standard negative validation for PHP.
Ignored checks are a special type of negative checks. Once you (or someone else) notice a bug via a negative check, you don’t want it to be reported again (until it gets fixed). You can mark such bug as ignored.
Standard PHP detection class supports this (which works with Xdebug or without it). You fill in XPath logical condition(s) that match bugs to be ignored. Alternatively, you can create a custom detection class and provide the logic to filter out ignored bugs.
Positive checks validate that the page contains elements that match given selector(s). However, it can’t validate that HTML of a page conforms to HTML standard. That’s because Firefox automatically fixes incorrect HTML and it adds missing necessary elements.
Configure these checks at chrome:// URL chrome://selite-settings/content/tree.xul?module=extensions.selite-settings.common. In order to use Auto Check you must select at least
autoCheckDetectorCustom. Other fields are optional.
autoCheckAssert - whether an occurrence should trigger an assert failure; by default it triggers a validation failure rather than an assert failure
autoCheckDetector - choose a standard detection class to use; or set it to
undefined if you use a custom class
autoCheckDetectorCustom - enter a name of the custom detection class (which you must load into Core scope e.g. via Bootstrap); used only if
autoCheckIgnored - the format of entries depends on the detection class. Auto Check reports failures unless they match an
autoCheckIgnored entry. Use
autoCheckIgnored to match already reported bugs (so that they don’t get reported again).
contains(., 'Undefined variable')
autoCheckRefused - enter locator(s) to be refused; none of the locator(s) must match any element, otherwise the page fails
autoCheckRequired - enter locator(s) to be required; each locator must match at least one element, otherwise the page fails
(Those fields are not defined in chrome://selite-settings/content/common_settings_module.js. Instead, they are added on the fly by chrome://selite-auto-check/content/SeLiteExtensionSequencerManifest.js).
