Executing a Single Selenium Test in Play Framework via Command Line (Headless Mode)

Other Questions Headless Browser
1

I can successfully run individual Selenium tests through the Play Framework’s UI. However, I’m curious if there’s a method to initiate a Play Selenium test from the command line instead. When I use play auto-test, it triggers all my Selenium and JUnit tests. Is there a specific way to instruct Play to run just one Selenium test from the command line and verify its functionality using a headless browser?

To run a single Selenium test in a Play Framework project via the command line, you'll want to utilize the test framework directly rather than through the Play commands like play auto-test. This approach will offer you greater flexibility, particularly in running a single test and leveraging a headless browser for your Selenium tests.

Assuming you're using ScalaTest, you can execute a specific test by providing the fully qualified name of the test class. For a headless test execution, you can configure your WebDriver to run in headless mode. Here's how you can achieve that:

  1. First, configure your Selenium WebDriver to run in headless mode. If you are using Chrome, it might look something like this:
    import org.openqa.selenium.chrome.ChromeDriver;
    import org.openqa.selenium.chrome.ChromeOptions;

    ChromeOptions options = new ChromeOptions();
    options.addArguments("--headless");
    ChromeDriver driver = new ChromeDriver(options);

Make sure the headless option is configured in the setup for all tests that you want to execute in this mode.

  1. Run your test from the command line by specifying the test class directly. For example, if you are using sbt, you would run:
    sbt "testOnly path.to.your.TestClass"

This command instructs sbt to run only the specified test class. Adjust path.to.your.TestClass to the package and class name of the test you want to execute.

This method allows you to focus on a single test, ensuring it runs headless, and thus you can easily verify its functionality without triggering the entire test suite.

To run a single Selenium test from the command line in Play Framework, use the test framework directly by specifying the test class. Configure your WebDriver to be headless. Here's a quick setup:

  1. Set up the headless mode. For Chrome, use:
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;

ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
ChromeDriver driver = new ChromeDriver(options);
  1. Run your test with sbt, specifying the test class:
sbt "testOnly path.to.your.TestClass"

Replace path.to.your.TestClass with your specific test class. This allows running one test headlessly and efficiently.

To execute a single Selenium test in Play Framework using the command line while utilizing a headless browser, you'll use the test framework directly to run only the desired test. Here's how to set it up:

  1. Configure Headless Mode: You need to set up your Selenium WebDriver to work in headless mode. For instance, in Chrome, you can do it like this:
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;

ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
ChromeDriver driver = new ChromeDriver(options);
  1. Run the Test: Use sbt to invoke a specific test class. Execute this command in your terminal:
sbt "testOnly path.to.your.TestClass"

Make sure to replace path.to.your.TestClass with the fully qualified name of your test class. This allows you to run your Selenium tests headlessly without executing the entire suite, ensuring efficiency and focused testing.
