You can try @Rule
annotation. Here is the example from the docs:
public static class UsesExternalResource {
Server myServer = new Server();
@Rule public ExternalResource resource = new ExternalResource() {
@Override
protected void before() throws Throwable {
myServer.connect();
};
@Override
protected void after() {
myServer.disconnect();
};
};
@Test public void testFoo() {
new Client().run(myServer);
}
}
You just need to create FileResource
class extending ExternalResource
.

Continuous Integration/Continuous Deployment (CI/CD) has become an essential part of modern software development cycles. As a part of continuous integration, the developer should ensure that the Integration should not break the existing code because this could lead to a negative impact on the overall quality of the project. In order to show how the integration process works, we’ll take an example of a well-known continuous integration tool, TeamCity. In this article, we will learn TeamCity concepts and integrate our test suites with TeamCity for test automation by leveraging LambdaTest cloud-based Selenium grid.

Automation testing at first may sound like a nightmare especially when you have been into the manual testing business for quite long. Looking at the pace with which the need for automation testing is arising, it has become inevitable for website testers to deep dive into the automation river and starts swimming. To become a pro swimmer it takes time, similar is the case with becoming a successful automation tester. It requires knowledge & deep understanding of numerous automation tools & frameworks. As a beginner in automation testing, you may be looking forward to grabbing your hands on an open-source testing framework. After doing so the question that arises is what next? How do I go about using the open-source tool, framework, or platform, & I am here to help you out in that regard. Today, we will be looking at one of the most renowned open-source automation testing frameworks known as Selenium. In this Selenium Java tutorial, I will demonstrate a Selenium login example with Java to help you automate the login process.
