ParameterizedTest Multiple Parameters with csvSource
In JUnit 5, @ParameterizedTest allows you to run the same test multiple times with different inputs. When you need to pass multiple parameters, you can use @CsvSource, which lets you specify multiple sets of values in a comma-separated format. Each set of values is passed as arguments to the test method.

ParameterizedTest Multiple Parameters with MethodSource
In JUnit 5, you can use @ParameterizedTest and @MethodSource to provide multiple parameters for a test method. @MethodSource allows you to provide test data in a unique method that returns a stream, list, or other recursive collection.

Parameterized test csv File
In JUnit 5, you can use @ParameterizedTest and @CsvFileSource to provide multiple parameters from a CSV file. This is useful when you have a large number of test cases maintained in an external file

ParameterizedTest ValueSource annotation
In JUnit 5, the @ValueSource annotation is used with @ParameterizedTest to pass a simple set of data types to a test method. @ValueSource can handle primitive types, strings, and classes, making it ideal for testing methods with multiple inputs of the same data type.

Repeated Test
In JUnit 5, the @RepeatedTest annotation allows you to execute the same test over and over again. This can be useful for ensuring that the test always passes or for simulating situations that require multiple iterations.

Method order and random order
In JUnit 5, you can control the order in which test methods are executed within a test class using the @TestMethodOrder annotation. By default, JUnit does not guarantee any specific order, but you can specify either a fixed order or a random order for your tests.

Method order order by name
In JUnit 5, you can control the order of test execution by specifying that tests should be run in alphabetical order of their method names. To do this, you use the @TestMethodOrder annotation with MethodOrderer.MethodName.

Methods Order Random by order index
JUnit 5 does not directly support the use of test methods in random order while controlled use of specific priorities or indexes. Instead, you can use @TestMethodOrder(MethodOrderer.Random.class) to randomize the test order, but if you need to mix randomness as a priority, you will usually need a custom method orderer or workaround that handles test execution manual Order to ensure randomization of products.

Order unit test classes
To configure unit test classes in JUnit 5, you can use the @TestMethodOrder annotation with the MethodOrderer option, but this method only applies to methods in the class. If you want to control the order in which the test classes are controlled, you typically have to manage this through your build tool or test scheduling system, as JUnit 5 does not provide built-in support for setting up test classes directly.

Test Instance Lifecycle Introduction
The test instance lifecycle in JUnit 5 determines how test class instances are created and managed. By default, a new instance of the test class is created for each test method, ensuring that the test is isolated. Alternatively, using @TestInstance(Lifecycle.PER_CLASS) allows all test methods to use a single instance of the test class, which can be useful for a shared environment and better performance.
