Example 1 with SeleniumGridNodeNotAvailable

use of com.seleniumtests.customexception.SeleniumGridNodeNotAvailable in project seleniumRobot by bhecquet.

the class SeleniumGridDriverFactory method getDriver.

/**
 * Connect to grid using RemoteWebDriver
 * As we may have several grid available, takes the first one where driver is created
 *
 * Several waits are defined
 * By default, we wait 30 mins for a node to be found. For this, we loop through all available hubs
 * In case we do not find any node after 30 mins, we fail and increment a fail counter
 * This fail counter is reset every time we find a node
 * If this counter reaches 3, then we don't even try to get a driver
 *
 * @param url
 * @param capability
 * @return
