junit5

The Description: I would like to create a JUnit test using JUnit 5 in Eclipse (Oxygen 4.7.1a) . This JUnit test should be inside a seperate src folder called Test. However, I ran into the following problems as I'm new to JUnit and Java 9 . I do not want to use build tools like Gradle or Maven for this. The Problem: As I've got two different src folders, one for the projects src and one for the test cases: Do I need two module-info.java files? (one for each src folder) Which modules are required in my module-info.java file for JUnit 5 to work? In general there is no need to modularize your test

We are using an approach similar to System Rules to handle (system) properties in our JUnit 4 tests. The main reason for this is to clean up the environment after each test, so that other tests do not inadvertently depend on possible side effects. Since JUnit 5 is released, I wonder if there is a "JUnit 5 way" of doing this? You can use the extension API . You could create an annotation which defines your extension to a test method. import org.junit.jupiter.api.extension.ExtendWith; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation

In JUnit 4 it was easy to test invariants across a bunch of classes by using the @Parameterized annotation. The key thing is that a collection of tests are being run against a single list of arguments. How to replicate this in JUnit 5, without using JUnit-vintage? @ParameterizedTest is not applicable to a test class. @TestTemplate sounded like it might be appropriate, but that annotation's target is also a method. An example of such a JUnit 4 test is: @RunWith( Parameterized.class ) public class FooInvariantsTest{ @Parameterized.Parameters public static Collection<Object[]> data(){ return new

Is there already a possibility to generate an HTML report when JUnit tests were started via Gradle? Any hint or comment is appreciated. UPDATE Gradle 4.6 provides built-in support for the JUnit Platform which allows you to run JUnit Jupiter tests using the standard Gradle test task which generates HTML reports out of the box. Answer for Gradle versions prior to 4.6 The JUnit Platform Gradle Plugin generates JUnit 4 style XML test reports. These XML files are output to build/test-results/junit-platform by default. So, if your build server knows how to parse JUnit 4 style XML reports, you can

I've got a gradle FAILURE: ..."Deprecated Gradle features were used in this build, making it incompatible with Gradle 5.0." Case description: Attached to the project codebase the next libs: APP/build.gradle //(Required) Writing and executing Unit Tests on the JUnit Platform testImplementation "org.junit.jupiter:junit-jupiter-api:5.2.0" testRuntimeOnly "org.junit.jupiter:junit-jupiter-engine:5.2.0" // (Optional) If you need "Parameterized Tests" testImplementation "org.junit.jupiter:junit-jupiter-params:5.2.0" // (Optional) If you also have JUnit 4-based tests testImplementation "junit:junit:4

Is there any reason to group multiple assertions: public void shouldTellIfPrime(){ Assertions.assertAll( () -> assertTrue(isPrime(2)), () -> assertFalse(isPrime(4)) ); } instead of doing this: public void shouldTellIfPrime(){ Assertions.assertTrue(isPrime(2)); Assertions.assertFalse(isPrime(4)); } The interesting thing about assertAll is that it always checks all of the assertions that are passed to it , no matter how many fail. If all pass, all is fine - if at least one fails you get a detailed result of all that went wrong (and right for that matter). It is best used for asserting a set of
