## What it is
PowerMock is a Java framework that extends mocking libraries like EasyMock and Mockito to enable unit testing of code normally regarded as untestable. It uses a custom classloader and bytecode manipulation to mock static methods, constructors, final classes and methods, private methods, and static initializers.

## Use cases
- mock static methods in java unit tests
- mock final classes and methods
- suppress static initializer blocks in tests
- test legacy code with private method mocking
- extend mockito tests to untestable code
- bypass encapsulation to access internal state in tests

## When to choose
- you need to unit test legacy Java code with static methods, final classes, or private methods
- you already use Mockito or EasyMock and need more powerful mocking capabilities
- you cannot refactor production code for testability

## When to avoid
- you are starting a new project and can design for testability with plain Mockito
- your team includes junior developers, as PowerMock can encourage poor design
- you need a actively developed tool with modern JDK support

## Facets
- artifact type: framework
- maturity: maintenance
- function: testing, mocking
- domain: testing, developer-tools
- platform: jvm
- tags: java, mockito, easymock, bytecode-manipulation, unit-testing
