Apply universal RPA driver

The universal driver provides the following benefits for rapid RPA scripts development:

• You do not need to switch between drivers and create multiple robot plugins.
• You can use the universal driver in 99% of Use Cases. Almost all RPA Use Cases don't need complex driver-juggling with transactions handling and support.

To use the universal driver, complete the following conditions:

1. In the robot plugin, set the driver="universal" attribute.
2. Add a capability inside the robot plugin: <capability name="SEARCH_ALL_WINDOWS" value="true" />

Set driver type in universal driver explicitly

While using the universal driver in complex Use Cases, the driver auto-switching algorithm can fail to automatically detect which application (web or desktop) should accept the current action, for example:

$(byXpath("//input[@id='searchInput']")).click()                 // web

switchTo().window('[CLASS:SunAwtFrame; TITLE:SwingSet2]')
$(byXpath("//*[@text='Eyes']/following-sibling::*")).click()     // desktop

To handle such cases, use an explicit driver switching methods that accept a closure with all actions for this driver:

• inDesktop{}
• inChrome{}
• inFirefox{}
• inEdge{}
• inIE{}

For instructions that are outside the closure, the default auto-switching mechanism is applied.

The explicit driver closures improve the stability and readability of your code.
