Hi Henry,
Very good question. Tellurium offers the following three running modes
1) Core generates runtime XPath locator (default)
2) Core generates runtime CSS selector locator
3) Santa algorithm in Engine locates all UI elements in one shot.
useCssSelector() is used to switch between 1) and 2).
For 3), you need to use
useCache(true)
but Core still generates the runtime locators (xpath or css selector
dependent on the command useCssSelector)
and these runtime locators are actually ignored by Engine for most cases.
The special case is that you have your
custom UI object and your special way to generate the runtime locators for
your custom object. You can define a custom
UI object at Engine, otherwise, you still have to rely on the core generated
runtime locators.
Tellurium Engine offers a set of APIs same as the ones in Selenium Core, but
re-implemented by jQuery and a set of
extra APIs that only exist in Tellurium Engine. The useTelluriumApi()
command is used to switch between Selenium API
and Tellurium API.
The useTelluriumEngine command is a short for the following commands
void useTelluriumEngine(boolean isUse){
useCache(isUse);
useMacroCmd(isUse);
useTelluriumApi(isUse);
}
As you can see, Tellurium offers you the capability to write environment
agnostic test code and you can run them in different
modes as you like.
Hope this can help.
Thanks,
Jian
