In this REST Assured tutorial, I will demonstrate how to evaluate the JSON content that is returned in the response body of an HTTP response. What is REST Assured? REST Assured is a Java-based library for testing RESTful web services. It provides a domain-specific language (DSL) for writing tests that interact with web services using…
Read More Validate JSON Response with REST AssuredThis short REST Assured tutorial will teach you how to validate the HTTP Response Status Code while testing a RESTful Web Service endpoint. Each HTTP Response includes a status code, and by examining the status code value, we can determine if the HTTP Response was successful or not. Let’s explore how we can use REST…
Read More Validate HTTP Status Code: RestAssuredMockito enables partial mocking of an object, allowing us to create a mock object while still invoking a real method. To achieve this, we can use Mockito’s thenCallRealMethod() method to call a real method on a mocked object. I have also created several step-by-step video lessons that demonstrate how to test Java applications. If you…

In this blog post, I’ll show you how to do just that: run a specific unit test using Maven from the command line. For video tutorials…
Read More Running a Single Unit Test with MavenIn this tutorial, you will learn how to write a JUnit test that validates whether the method under test throws the correct exception. The tutorial includes examples for both JUnit 5 and JUnit 4. For video lessons, check out my video course: Testing Java with JUnit and Mockito. Let’s begin with JUnit 5 version first.…
Read More Test for Exception in JUnit 5 and JUnit 4This tutorial will teach you how to build a Maven-based Spring Boot project and skip Unit tests. Sometimes, when working on a project, we need to build and run it even though our Unit test is failing. When there is a flailing Unit test, the Maven package and install commands will also fail. This is because…
