Repeated tests

JUnit Jupiter provides for the ability to repeat a test a specified number of times simply by annotating a method with @RepeatedTest, specifying the total number of repetitions desired. Each repeated test behaves exactly as a regular @Test method. Moreover, each repeated test preserves the same lifecycle callbacks (@BeforeEach, @AfterEach, and so on).

The following Java class contains a test that is going to be repeated five times:

package io.github.bonigarcia;

import org.junit.jupiter.api.RepeatedTest;

class SimpleRepeatedTest {

    @RepeatedTest(5)
void test() {
        System.out.println("Repeated test");
    }

}

Due to the fact that this test only writes a line (Repeated test) in the standard output, when executing this test in the console, we will see that trace five times:

In addition to specifying the number of repetitions, a custom display name can be configured for each repetition via the name attribute of the @RepeatedTest...
