Java JUnit: The method X is ambiguous for type Y
If you add in Hamcrest and JUnit4, you could do:
String x = "foo bar";
Assert.assertThat(x, CoreMatchers.containsString("foo"));
With some static imports, it looks a lot better:
assertThat(x, containsString("foo"));
The static imports needed would be:
import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.CoreMatchers.containsString;

In today’s digital age, product teams must build products at a brisk pace while maintaining the best quality. Therefore, the methodology to follow and the tool selection to accomplish this can be paramount to get better results. Moreover, software applications don’t just support businesses now; rather, they have become an integral part of a business. Hence, it’s obvious that the product teams deliver a product with speed, reliability, scale, security, quality, and improved collaboration. So companies started following the DevOps model, which is a combination of Development (Dev) and Operations (Ops) teams.
So you are at the beginning of 2020 and probably have committed a new year resolution as a tester to take a leap from Manual Testing To Automation . However, to automate your test scripts you need to get your hands dirty on a programming language and that is where you are stuck! Or you are already proficient in automation testing through a single programming language and are thinking about venturing into new programming languages for automation testing, along with their respective frameworks. You are bound to be confused about picking your next milestone. After all, there are numerous programming languages to choose from.
Both JUnit and TestNG are popular unit testing frameworks that have been widely accepted by Java developers. JUnit was introduced as an open-source unit testing framework for Java way back in 1997. In fact, JUnit is one of the widely used test automation frameworks for test automation. TestNG is another Java-based test automation framework that is not only open-source but also offers awesome features that are best suited for large-scale web automation testing. TestNG was created for a range of testing categories, including (but not limited to) unit testing, functional testing, end-to-end testing, and integration testing.
CI/CD pipelines are here to stay and contribute tremendously to continuous integration and delivery across all global projects. This article will be a guide to configure, set up builds and tests with “GitHub Actions”, primarily using Selenium WebDriver. This article shall also cover some of the most generic GitHub Actions examples, and user flows.
