How does selenium deviate from the trend
WebNov 28, 2024 · When you look up an element Selenium first checks if its cached. If not, it uses SearchContext which finds all elements within the current context (eg. DOM element) using a given mechanism, for example by XPathEvaluator. SearchContext runs findElement () if you are looking for one element or findElements () if you are looking for more than one. WebSelenium has both a photovoltaic action (converts light to electricity) and a photoconductive action (electrical resistance decreases with increased illumination). It is therefore useful in photocells, solar cells and photocopiers. It can also convert AC electricity to DC electricity, so is extensively used in rectifiers.
