What is the process for compiling Kotlin unit test code that utilizes the hamcrest 'is' method?

edit

1. Install the Kotlin unit testing framework, such as JUnit or Spek.
2. Import the hamcrest library to the project.
3. In the code, import the hamcrest 'is' method using the following statement: import org.hamcrest.CoreMatchers.is;
4. Write the unit test code using the 'is' method to assert the expected value. For example:

import org.hamcrest.CoreMatchers.`is`
import org.junit.Test

class ExampleUnitTest {
    @Test
    fun addition_isCorrect() {
        val result = 2 + 2
        assertThat(result, `is`(4))
    }
}

1. Compile the Kotlin code and run the unit tests.
