JavascriptExecutor excute = (JavascriptExecutor) driver ;

        String asset=driver.findElement(By.xpath("//div[@ng-repeat='asset in arParameters.assets']/a")).getText();
        driver.findElement(By.xpath("//div[@ng-repeat='asset in arParameters.assets']/a")).click();
        //Thread.sleep(5000);
        String link =driver.findElement(By.xpath("//video[@name='media']/source")).getAttribute("src");
        excute.executeScript("alert('"+link+"')");
        Thread.sleep(10000);
        driver.get(baseUrl+"productions/cue_sheets/diag?ws=b54fb782-5865-408e-8f54-b1dea2d622c0&id=32c8aedd-b522-4580-b393-651f295fa1c0");

        try {
            assertEquals(link,asset);
        } catch (Error e) {
            verificationErrors.append(tcID+": "+e.toString());
        }
