Eventhandling

The following functions are supported: on,once,emit,removeListener,removeAllListeners. They behave exactly as described in the official NodeJS docs. There are some predefined events (error,init,end, command) which cover important WebdriverIO events.

Example

client.on('error', function(e) {
    // will be executed everytime an error occured
    // e.g. when element couldn't be found
    console.log(e.body.value.class);   // -> "org.openqa.selenium.NoSuchElementException"
    console.log(e.body.value.message); // -> "no such element ..."
})

All commands are chainable, so you can use them while chaining your commands

    })

        cnt = res.value;
    })
    .emit('countme', cnt)
    .end();
