New: JUnit 5 support in Gradle 4.6 As pointed out in this GitHub issue from Gradle 4.6 onwards JUnit 5 is supported! Official release notes of 4.6 (at the moment of editing the latest, but check the GitHub releases page to make sure you use the latest version) at docs.gradle.org. The old setup will still … Read more
Here are two possibilities to achieve these multi argument test method calls. The first (testParameters) uses a CsvSource to which you provide a comma separated list (the delimiter is configurable) and the type casting is done automatically to your test method parameters. The second (testParametersFromMethod) uses a method (provideParameters) to provide the needed data. @ParameterizedTest … Read more
You have to make sure Hamcrest is included in the classpath and then use the assertThat() function provided by Hamcrest. From the current JUnit 5 User Guide – Writing Tests Assertions, JUnit Jupiter’s org.junit.jupiter.Assertions class does not provide an assertThat() method like the one found in JUnit 4’s org.junit.Assert class which accepts a Hamcrest Matcher. … Read more
In my case the problem was that the @Test annotation was taken from wrong import. Originally it was imported from org.junit.Test. Once I have switched it to org.junit.jupiter.api.Test the problem was resolved. Wrong original code: import org.junit.Test; @BeforeEach …some code @Test …some code Correct fixed code: import org.junit.jupiter.api.Test; @BeforeEach …some code @Test …some code
This might also be caused if you try to verify a method which expects primitive arguments with any(): For example, if our method has this signature: method(long l, String s); And you try to verify it like this, it will fail with aforementioned message: verify(service).method(any(), anyString()); Change it to anyLong() and it will work: verify(service).method(anyLong(), … Read more
If you are using Junit version < 5, so you have to use @RunWith(SpringRunner.class) or @RunWith(MockitoJUnitRunner.class) etc. If you are using Junit version = 5, so you have to use @ExtendWith(SpringExtension.class) or @ExtendWith(MockitoExtension.class) etc. SpringRunner MockitoJUnitRunner SpringExtension MockitoExtension
In a general way, what you did with @Rule and @ClassRule in JUnit 4 should be done with @ExtendWith and Extension that associated provide a very close feature in JUnit 5. It works as standards JUnit lifecycle hooks but that it is extracted in a Extension class. And similarly to @Rule, as many Extensions as … Read more
I had both @Test and @ParameterizedTest annotating the same method. I removed the former.
I found the error. The dependency on spring-boot-starter-test brings a dependency on junit-vintage-engine. The latter must be excluded: <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency>
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 … Read more
