Assumptions - anastasiamexa/Healthy-Coder-App GitHub Wiki

Assumptions are useful when you have tests that depend on certain conditions, and those conditions are not met in the current environment. Rather than failing the test, assumptions allow you to gracefully skip the test when the necessary conditions are not satisfied. This is especially helpful for avoiding false negatives in test results when certain prerequisites are not met.

Here's a simple example:

import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assumptions.assumeTrue;

public class AssumptionsExample {
    private String environment = "dev";

    @Test
    void testOnDevelopmentEnvironment() {
        assumeTrue(this.environment.equals("prod"), "This test runs only in the development environment");

        // Test logic for the development environment
    }
}

In this example, the test will be skipped unless the environment is set to "dev." If the assumption fails, the test is skipped and not marked as a failure.
