Installation

<dependency>

</dependency>

Example usage

Annotate your test class with @ExtendWith(Predict.class):

import net.gamrath.junitpredict.Predict;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;

@ExtendWith(Predict.class)
class MyTest {
    @Test
    void foo() {
        // ...
    }
}

When you run your tests, a dialog will prompt you to predict if all tests will pass or if any will fail. After the tests run, you'll see a dialog showing if your prediction was correct, and results will be logged to a CSV file in your project root.
