announcement - icon User management is very complex, when implemented properly. No surprise here.

Not having to roll all of that out manually, but instead integrating a mature, fully-fledged solution - yeah, that makes a lot of sense.
That's basically what Frontegg is - User Management for your application. It's focused on making your app scalable, secure and enjoyable for your users.
From signup to authentication, it supports simple scenarios all the way to complex and custom application logic.

NPI – Lightrun – Spring (partner)

We rely on other people’s code in our own work. Every day. It might be the language you’re writing in, the framework you’re building on, or some esoteric piece of software that does one thing so well you never found the need to implement it yourself.

The problem is, of course, when things fall apart in production - debugging the implementation of a 3rd party library you have no intimate knowledge of is, to say the least, tricky. It’s difficult to understand what talks to what and, specifically, which part of the underlying library is at fault.

Lightrun is a new kind of debugger.

It's one geared specifically towards real-life production environments. Using Lightrun, you can drill down into running applications, including 3rd party dependencies, with real-time logs, snapshots, and metrics. No hotfixes, redeployments, or restarts required.

>> The Essential List of Spring Boot Annotations and Their Use Cases

1. Introduction

In this quick article, we'll discover the @EnabledIf and @DisabledIf annotations in Spring 5 using JUnit 5.

Simply put, those annotations make it possible to disable/enable particular test if a specified condition is met.

We'll use a simple test class to show how these annotations work:

@SpringJUnitConfig(Spring5EnabledAnnotationIntegrationTest.Config.class)
public class Spring5EnabledAnnotationIntegrationTest {
 
    @Configuration
    static class Config {}
}

2. @EnabledIf

Let's add to our class this simple test with a text literal “true”:

@EnabledIf("true")
@Test
void givenEnabledIfLiteral_WhenTrue_ThenTestExecuted() {
    assertTrue(true);
}

If we run this test, it executes normally.

However, if we replace the provided String with “false” it's not executed:

Captura test

Keep in mind that if you want to statically disable a test, there's a dedicated @Disabled annotation for this.

3. @EnabledIf With a Property Placeholder

A more practical way of using @EnabledIf is by using a property placeholder:

@Test
@EnabledIf(
  expression = "${tests.enabled}", 
  loadContext = true)
void givenEnabledIfExpression_WhenTrue_ThenTestExecuted() {
    // ...
}

First of all, we need to make sure that the loadContext parameter is set to true so that the Spring context gets loaded.

By default, this parameter is set to false to avoid unnecessary context loading.

4. @EnabledIf With a SpEL Expression

Finally, we can use the annotation with Spring Expression Language (SpEL) expressions.

For example, we can enable tests only when running JDK 1.8

@Test
@EnabledIf("#{systemProperties['java.version'].startsWith('1.8')}")
void givenEnabledIfSpel_WhenTrue_ThenTestExecuted() {
    assertTrue(true);
}

5. @DisabledIf

This annotation is the opposite of @EnabledIf.

For example, we can disable test when running on Java 1.7:

@Test
@DisabledIf("#{systemProperties['java.version'].startsWith('1.7')}")
void givenDisabledIf_WhenTrue_ThenTestNotExecuted() {
    assertTrue(true);
}

6. Conclusion

In this brief article, we went through several examples of the usage of @EnabledIf and @DisabledIf annotations in JUnit 5 tests using the SpringExtension.

The full source code for the examples is available over on GitHub.
