fixtures

• state or data you set up before running tests
• create a consistent environment for your tests to execute in
• Includes
  • Initializing database records
  • Setting up mock objects or services
  • Creating test user accounts

Example

setup:
    def user = new User(name: "Bob")
    userService.save(user)  // Assume userService is a mock or real service

when:
    def foundUser = userService.findById(user.id)

then:
    foundUser == user

Closures in Fixtures

You can often use closures within fixtures to define the actions that need to be performed to set up the test environment:

def setupDatabase = { 
    // Code to populate the database with test data
}

setup:
    setupDatabase() 

Key Takeaways:

• Closures: Blocks of code that capture their environment.
• Fixtures: Test data or state used to create a consistent testing environment.
• Groovy: Provides excellent support for both closures and fixtures, making them powerful tools for testing and other tasks.
