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 distributing your tests on multiple machines, enhanced finding and waiting of elements, and providing an improved browser life cycle control and the ability to run tests in headless mode.

Parallel and Distributed Test Execution

Test execution runner that speeds up your test execution using your whole hardware capacity. BELLATRIX comes with its test runner- Meissa, that can run tests on Windows, MacOS, and Linux. Meissa speeds up the tests by distributing them on multiple machines. The test execution can be further improved by executing the tests in parallel through tests agents.

  • Smart Tests Balancing

    Smartly balances the tests across remote machines based on previous tests execution times which can significantly improve the overall test run time.

  • Failing Tests Retry

    Has the capability to retry failing tests multiple times to see whether there are bugs in the tests, real problems in the system under the test, or some random environmental issues occurring during the run.

  • Safe Test Run Abortion

    Keeps the clean state of test agents and provides a fast test run abortion.

  • Built-in Extendability

    Executes custom logic through plug-in API without modifying the source code.

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 page right now.

If you use global timeouts such as WebDriver implicit wait.

IWebDriver driver = new ChromeDriver(); 
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.

Thread.Sleep(2000);

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 Browser Life Cycle Control

Reuse the browser and configure it when to restart.

Two of the operations that take the most time in web tests are related to starting and closing the web browsers. Each of these operations can take from a fraction of a second to several seconds. If you open and close the browser 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 browser life cycle across multiple tests. You need to set this behavior in the Browser attribute applied to each test class.

[Browser(BrowserType.Firefox, BrowserBehavior.ReuseIfStarted)]
public class BellatrixBrowserBehaviourTests : WebTest

The browser lifecycle is configured through the browser behavior property. Available options:

  • RestartEveryTime

    For each test a separate WebDriver instance is created and the previous browser is closed.

  • RestartOnFail

    The browser is only restarted if the previous test failed.

  • ReuseIfStarted

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

Run Tests in Headless Mode

Your tests execute even faster if you use the so-called headless mode.

BELLATRIX supports all 5 major browsers- Chrome, Firefox, Edge, Opera and Internet Explorer. In this mode, tests run in the browser but the browser’s UI is not rendered. In theory, it should be faster.
BELLATRIX can run tests in headless mode using Chrome and Firefox engines.

You just need to set the ChromeHeadless or FirefoxHeadless for browser type in the Browser attribute.

[Browser(BrowserType.FirefoxHeadless, BrowserBehavior.ReuseIfStarted)]

All tests in the class will be executed in Firefox browser in headless mode.
