You should not need to test private methods.

  • A private method is specifically part of the implementation. You should not test the implemenation, but the functionality. If you test the functionality a class exposes, you can change the implementation while depending on the unit test.
  • If you feel the need to test a private method, this is a good sign that you should move the private method to another class and make the method public. By doing this, you get smaller classes and you can test the methods easily. If you do not want to expose this new class, you can make it package-private (the default access modifier).

Top Selenium C# Frameworks For Automation Testing In 2020

With the ever-increasing number of languages and frameworks, it’s quite easy to get lost and confused in this huge sea of all these frameworks. Popular languages like C# provide us with a lot of frameworks and it’s quite essential to know which particular framework would be best suited for our needs.

Gauge Framework – How to Perform Test Automation

Gauge is a free open source test automation framework released by creators of Selenium, ThoughtWorks. Test automation with Gauge framework is used to create readable and maintainable tests with languages of your choice. Users who are looking for integrating continuous testing pipeline into their CI-CD(Continuous Integration and Continuous Delivery) process for supporting faster release cycles. Gauge framework is gaining the popularity as a great test automation framework for performing cross browser testing.

TestNG Listeners In Selenium WebDriver With Examples

There are different interfaces provided by Java that allows you to modify TestNG behaviour. These interfaces are further known as TestNG Listeners in Selenium WebDriver. TestNG Listeners also allows you to customize the tests logs or report according to your project requirements.

Why Selenium WebDriver Should Be Your First Choice for Automation Testing

Developed in 2004 by Thoughtworks for internal usage, Selenium is a widely used tool for automated testing of web applications. Initially, Selenium IDE(Integrated Development Environment) was being used by multiple organizations and testers worldwide, benefits of automation testing with Selenium saved a lot of time and effort. The major downside of automation testing with Selenium IDE was that it would only work with Firefox. To resolve the issue, Selenium RC(Remote Control) was used which enabled Selenium to support automated cross browser testing.

How To Build CI/CD Pipeline With TeamCity For Selenium Test Automation

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.

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.
