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;

Building Automated Testing Pipeline With Semaphore CI And Selenium Grid

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.

Top 7 Programming Languages For Test Automation In 2020

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.

How To Run JUnit Selenium Tests using TestNG

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.

Complete Guide To Selenium Testing with GitHub Actions

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.

How To Setup JUnit Environment For Your First Test?

This article is a part of our Content Hub. For more in-depth resources, check out our content hub on JUnit Tutorial.

JUnit Tutorial:

LambdaTest also has a detailed JUnit tutorial explaining its features, importance, advanced use cases, best practices, and more to help you get started with running your automation testing scripts.

JUnit Tutorial Chapters:

Here are the detailed JUnit testing chapters to help you get started:

  • Importance of Unit testing - Learn why Unit testing is essential during the development phase to identify bugs and errors.
  • Top Java Unit testing frameworks - Here are the upcoming JUnit automation testing frameworks that you can use in 2023 to boost your unit testing.
  • What is the JUnit framework
  • Why is JUnit testing important - Learn the importance and numerous benefits of using the JUnit testing framework.
  • Features of JUnit - Learn about the numerous features of JUnit and why developers prefer it.
  • JUnit 5 vs. JUnit 4: Differences - Here is a complete comparison between JUnit 5 and JUnit 4 testing frameworks.
  • Setting up the JUnit environment - Learn how to set up your JUnit testing environment.
  • Getting started with JUnit testing - After successfully setting up your JUnit environment, this chapter will help you get started with JUnit testing in no time.
  • Parallel testing with JUnit - Parallel Testing can be used to reduce test execution time and improve test efficiency. Learn how to perform parallel testing with JUnit.
  • Annotations in JUnit - When writing automation scripts with JUnit, we can use JUnit annotations to specify the type of methods in our test code. This helps us identify those methods when we run JUnit tests using Selenium WebDriver. Learn in detail what annotations are in JUnit.
  • Assertions in JUnit - Assertions are used to validate or test that the result of an action/functionality is the same as expected. Learn in detail what assertions are and how to use them while performing JUnit testing.
  • Parameterization in JUnit - Parameterized Test enables you to run the same automated test scripts with different variables. By collecting data on each method's test parameters, you can minimize time spent on writing tests. Learn how to use parameterization in JUnit.
  • Nested Tests In JUnit 5 - A nested class is a non-static class contained within another class in a hierarchical structure. It can share the state and setup of the outer class. Learn about nested annotations in JUnit 5 with examples.
  • Best practices for JUnit testing - Learn about the best practices, such as always testing key methods and classes, integrating JUnit tests with your build, and more to get the best possible results.
  • Advanced Use Cases for JUnit testing - Take a deep dive into the advanced use cases, such as how to run JUnit tests in Jupiter, how to use JUnit 5 Mockito for Unit testing, and more for JUnit testing.
