What is ExtendWith?
@ExtendWith is a repeatable annotation that is used to register extensions for the annotated test class, test interface, test method, parameter, or field.

What is application properties in spring boot?

How do I use @testpropertysource?
This example demonstrates how to use @TestPropertySource. It is a class-level annotation that is used to specify which properties files should be loaded when running the test class. Test property sources have the highest precedence than all other properties sources. That means Test source will override all other properties.
What is the use of @testpropertysource annotation in spring test?

The inlined properties loaded from @TestPropertySource have higher precedence over the properties loaded from resource locations using @TestPropertySource annotation in Spring integration test.
What is test source in testing?
It is a class-level annotation that is used to specify which properties files should be loaded when running the test class. Test property sources have the highest precedence than all other properties sources. That means Test source will override all other properties. Dependencies and Technologies Used:
What is the use of test property files in Java?
The properties loaded by @TestPropertySource have higher precedence over the properties loaded from Java system properties, operating system’s environments, property sources added by @PropertySource or programmatically. So the test property files can be used to override properties defined in system and application property sources.
