selenium-screenshot-watcher

Allows you to take a screenshot of the page on which your automated tests are on, that can be compared later on.

How it works ?

• "tell to the tool when to take a screenshot" along with some params user to store the image & later to identify it
• "tell to the tool to do a compare" of your screenshot
  • the tool is going to look for any image existence in the DB based on the params above, and report back to you
• tell your tests when to PASS or FAIL based on what the tool speaks back

Example:

public class ScreenTest {
    @Test
    public void blinkTest() {
        // Provide the URL where the tool runs
        // In this example you could rely on the heroku instance
        String baseURL = "http://selenium-screenshot-watcher.herokuapp.com/";
        WebDriver driver = new ChromeDriver();
        driver.get("http://www.google.ro");

        String testName = "heroku sample test - 1";
        String testBrowser = "chrome";
        String description = "running on localhost";

        // Initialize the tool
        ScreenshotWatcher watcher = new ScreenshotWatcher(driver, baseURL);

        // Takes a screenshot
        BaseScreenshotModel scrTaken = watcher.blink(testName, testBrowser, description);

        // Compares the screenshot
        CompareScreenshotsResponse compareResponse = watcher.compare(scrTaken);

        // assert if the images are the same, if not, they visit the review link
        assertTrue(compareResponse.getReviewLink(), compareResponse.isSameImage());
    }
}

Here is an example project that uses this tool: https://github.com/web-innovate/selenium-screenshot-watcher-sample

#Where are all the images stored ?

• In a mongoDB instance, either on cloud or locally
