Automated Browser

This library allows to quickly do an automated application controlling a browser for multiple purposes. An example of usage is to automate the generation of reports for external parties by accessing internal services, highlighting elements, taking screenshots and creating documents with them.

Installation

The dependency is available in maven central (see badge for version):

<dependency>
    <groupId>com.chavaillaz</groupId>
    <artifactId>automated-browser</artifactId>
</dependency>

Usage

An example of usage is available in the MavenCentralTest class. Its goal is to search the last version of a Maven artifact and take a screenshot of the code snippet to use.

Implementing your requirements

Stateful

In order to benefit from this library, create new classes extending AutomatedBrowser and use the methods available in it to simplify the implementation of your requirements.

An example of extension available in the tests of the project is the MavenCentral class. It can be used with:

try (MavenCentral browser = new MavenCentral(driver)) {
    browser.searchArtifact("org.slf4j:slf4j-api");
}

Stateful - Flow

There is also a possibility to have a flow with multiple steps defining your requirements, using the classes extending AutomatedBrowser you created:

try (MavenCentral browser = new MavenCentral(driver)) {
    browser.setData(new MavenCentralData("org.slf4j:slf4j-api"));
    new AutomatedBrowserFlow<>(browser)
        .withStep(MavenCentral::stepSearchArtifact)
        .withStep(MavenCentral::stepLogLastVersion)
        .withStep(MavenCentral::stepHighlightSnippet);
}

Note that you can also give a default exception handler for all step or a specific one overriding it for some steps.

Stateless - Flow

Also with the same flow system, you can have stateless calls to static methods. Those methods can have:

• No parameter
• One parameter: the class extending AutomatedBrowser you gave in the constructor (defaulting to AutomatedBrowser)
• Two parameters: first same as above and second the context data instance you can set with withContext method

try (MavenCentral browser = new MavenCentral(driver)) {
    new AutomatedBrowserFlow<MavenCentral, MavenCentralData>(browser)
        .withContext(new MavenCentralData("org.slf4j:slf4j-api"))
        .withStep(MavenCentralStep::stepSearchArtifact)
        .withStep(MavenCentralStep::stepLogLastVersion)
        .withStep(MavenCentralStep::stepHighlightSnippet);
}

Running your application

As a standalone application

Creates your preferred the driver using the methods in BrowserUtils:

• Chrome (getChromeDriver)
• Firefox (getFirefoxDriver)
• Edge (getEdgeDriver)

Then pass it to the classes you created (see chapter above) and start using them directly. Note that this will use the browsers available on your computer, meaning when you choose a browser driver in the code, you need that browser installed on your computer to make it working.

As a docker container

Thanks to test containers, you can also directly run it in a docker container containing the browser you want to use. For that, include the following dependencies in your project:

<dependency>
    <groupId>org.testcontainers</groupId>
    <artifactId>selenium</artifactId>
    <version>${test-containers.version}</version>
</dependency>

<dependency>
    <groupId>org.testcontainers</groupId>
    <artifactId>junit-jupiter</artifactId>
    <version>${test-containers.version}</version>
</dependency>

When it's done, add the @Testcontainers annotation on your test classes and the following attribute for the container (in this example Google Chrome):

@Container
public BrowserWebDriverContainer<?> chrome = new BrowserWebDriverContainer<>()
        .withCapabilities(getChromeOptions())
        .withRecordingMode(SKIP, null);

You can then access the driver with chrome.getWebDriver() and pass it when instantiating your classes.
