Unit Test Code

Unit Test Code export lets you generate test scaffolding directly from tabular data.

What is Unit Test Code Output?​

AnyWayData can export rows as data-driven test inputs for multiple frameworks (for example JUnit, pytest, Jest, xUnit, RSpec, PHPUnit, Kotest, and Perl test frameworks).

Generated output includes:

  • framework-appropriate imports/annotations
  • setup scaffold (optional)
  • provider or inline data strategy (framework dependent)
  • assertion scaffold mapped to each header

How is Unit Test Code output different from language data exports?​

Language data exports (JSON, Python, Java, etc.) produce data structures.

Unit Test Code output produces executable test scaffolding that:

  • includes framework test wrappers
  • loops/parameterizes rows as test cases
  • emits assertion templates for each column

Example Scaffold (JUnit 5)​

Example output using a provider strategy:

import static org.junit.jupiter.api.Assertions.assertEquals;
import java.util.stream.Stream;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.Arguments;
import org.junit.jupiter.params.provider.MethodSource;

public class GeneratedDataTests {
    static Stream<Arguments> data() {
        return Stream.of(
            Arguments.of("Connie", 21),
            Arguments.of("Miles", 34)
        );
    }

    @ParameterizedTest
    @MethodSource("data")
    void row_parameterized(Object... row) {
        Object[] expected = row;
        Object[] actual = mapRowUnderTest(row);
        assertEquals(expected[0], actual[0]); // Name
        assertEquals(expected[1], actual[1]); // Age
    }

    private Object[] mapRowUnderTest(Object[] input) {
        // Example: return PersonMapper.normalize(input);
        return input; // replace with your system-under-test call
    }
}

AnyWayData Support for Unit Test Code​

AnyWayData currently supports exporting to multiple unit-test frameworks across Java, JavaScript/TypeScript, Python, Ruby, PHP, Kotlin, and Perl.

See Unit Test Code Options for configuration details.
