AssertJ's assumptions don't work with Optionals

[NadChel]

AssertJ's assumptions don't work with Optionals. Do you think you can fix it?

This doesn't work:

package com.example;

import org.junit.jupiter.api.Test;

import java.util.Optional;

import static org.assertj.core.api.Assumptions.assumeThat;
import static org.assertj.core.api.InstanceOfAssertFactories.OPTIONAL;

public class AssumptionTest {
    @Test
    void testAssumptions() {
        assumeThat(Optional.of("something"))
                .asInstanceOf(OPTIONAL)
                .isPresent();
    }
}

java.lang.IllegalArgumentException: Unsupported assumption creation for class org.assertj.core.api.OptionalAssert

	at org.assertj.core.api.Assumptions.asAssumption(Assumptions.java:1364)
	at org.assertj.core.api.Assumptions.access$000(Assumptions.java:98)
	at org.assertj.core.api.Assumptions$AssumptionMethodInterceptor.intercept(Assumptions.java:118)

but this does:

package com.example;

import org.junit.jupiter.api.Test;

import java.util.Optional;

import static org.assertj.core.api.Assumptions.assumeThat;

public class AssumptionTest {
    @Test
    void testAssumptions() {
        assumeThat(Optional.of("something").isPresent())
                .isTrue();
    }
}

What version are you using? I couldn't reproduce the issue with 3.24.2.

Also, the intermediate .asInstanceOf(OPTIONAL) is unnecessary.

3.21.0

Please upgrade to the latest available considering that 3.21.0 is already two years old 🙂
