Accelerate Test Execution

To speed up the CI process, we developed a group of features that support every phаse of the process, from test creation to execution. Let’s take a look at how BELLATRIX can speed up your test execution by enhanced finding and waiting of elements, and providing an improved app life cycle control.

Optimized Element Finding and Waiting

Better finding and waiting of elements out of the box and flexible setup.

One of the most significant problems in test automation is handling timeouts and performing actions on elements which may not be on the screen right now.

If you use global timeouts such as WebDriver implicit wait.

AndroidDriver<AppiumWebElement> driver = new AndroidDriver<AppiumWebElement>(new Uri("", desiredCaps));
driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(30);

In some cases, you may need a larger wait interval. What do you do if this happens? One option is to increase the global timeout, but this will affect all existing tests, slowing down the whole test run significantly.
Another option is to use the global timeout and occasionally add hard-coded pauses in your tests where needed.


However, this is the worst thing you can do. One time you may need to wait 1 second, and another time 5 seconds. If you always use the biggest possible pause, your tests will get slower and slower.

BELLATRIX hides the whole complexity of searching and waiting for elements. All elements are returned immediately when they are present on the page in the right state.

Optimized App Life Cycle Control

Reuse the app and configure it when to restart.

Two of the operations that take the most time in Android tests are related to starting and closing the application under test. Each of these operations can take from a fraction of a second to several seconds. If you open and close the app for each test and you have thousands of tests, this can make your test runs more than twice as long!

To battle this problem, BELLATRIX offers an automatic way of handling the app life cycle across multiple tests. You need to set this behavior in the Android attribute applied to each test class.


The app life cycle is configured through the AppBehavior property. Available options:

  • RestartEveryTime

    For each test a separate Appium instance is created and the previous app is closed.

  • RestartOnFail

    The app is only restarted if the previous test failed.

  • ReuseIfStarted

    The app is only restarted if the previous test’s app was different. In all other cases, the app is reused if possible.

  • If you use one of the “restart on fail” or “reuse if started” options, it can significantly decrease the test execution time, eliminating the additional time for browser initialization and disposal.

Execute Tests in Docker Containers using Selenoid

Execute Tests in Docker Containers using Selenoid

Selenoid is a robust implementation of the Selenium hub using Docker containers to launch browsers. No need to manually install browsers or dive into WebDriver documentation. Any browser session can be saved to the H.264 video. An API to list, download, and delete saved log files. Suitable for personal usage and in big clusters.

To use BELLATRIX with Selenoid, you should use the Selenoid attribute instead of Browser. Selenoid has the same parameters as Browser but adds to additional ones- browser version, record video and save logs. As with the Browser attribute you can override the class behavior on Test level.
