Learn Java Unit Testing with JUnit 5 in 20 Steps - Step 14 - Tip - Repeat same test multiple times

This video tutorial explains the importance of running tests multiple times, especially when dealing with random values or asynchronous code. It introduces the 'repeated test' annotation in JUnit 5, a feature not available in JUnit 4, which allows tests to be executed a specified number of times. The tutorial provides practical examples and highlights scenarios where repeated testing is beneficial.

Why might you want to run the same test multiple times?

• To make the code more complex

• To ensure consistent behavior across different scenarios

• To save time during testing

• To reduce the number of test cases

What is a new feature in JUnit 5 that allows tests to be repeated?

• @TestMultiple

• @RepeatedTest

• @RepeatTest

• @TestRepeat

How does JUnit 5's @RepeatedTest differ from JUnit 4?

• JUnit 4 has a similar feature

• JUnit 5's feature is slower

• JUnit 5's feature is more complex

• JUnit 4 does not have this feature

In the example provided, how many times is the test repeated?

• 5 times

• 15 times

• 10 times

• 20 times

What is the benefit of using @RepeatedTest in scenarios where test behavior might vary?

• It makes the test run faster

• It helps identify inconsistent behavior

• It ensures the test passes every time

• It reduces the number of tests needed
