Annotation Type CartesianTest

@TestTemplate @ExtendWith(org.junitpioneer.jupiter.cartesian.CartesianTestExtension.class) @Target(METHOD) @Retention(RUNTIME) public @interface CartesianTest
@CartesianTest is a JUnit Jupiter extension that marks a test to be executed with all possible input combinations.

Methods annotated with this annotation should not be annotated with Test.

This annotation is somewhat similar to @ParameterizedTest, as in it also takes arguments and can run the same test multiple times. With @CartesianTest you don't specify the test cases themselves, though. Instead you specify possible values for each test method parameter (for example with @CartesianTest.Values) by annotating the parameters themselves and the extension runs the method with each possible combination.

You can specify a custom Display Name for the tests ran by @CartesianTest. By default it's [{index}] {arguments}.

For more details and examples, see the documentation on @CartesianTest.
