Examples with ALLOWS_NULL_VALUES com.google.common.collect.testing.features.MapFeature.ALLOWS_NULL_VALUES used on opensource projects

Example 1 with ALLOWS_NULL_VALUES

use of com.google.common.collect.testing.features.MapFeature.ALLOWS_NULL_VALUES in project guava by google.

the class MapComputeIfPresentTester method testComputeIfPresent_nullTreatedAsAbsent.

@MapFeature.Require({ SUPPORTS_PUT, ALLOWS_NULL_VALUES })
@CollectionSize.Require(absent = ZERO)
public void testComputeIfPresent_nullTreatedAsAbsent() {
    initMapWithNullValue();
    assertNull("computeIfPresent(presentAssignedToNull, function) should return null", getMap().computeIfPresent(getKeyForNullValue(), (k, v) -> {
        throw new AssertionFailedError();
    }));
    expectReplacement(entry(getKeyForNullValue(), null));
}

Example 2 with ALLOWS_NULL_VALUES

use of com.google.common.collect.testing.features.MapFeature.ALLOWS_NULL_VALUES in project guava by google.

the class MapMergeTester method testMappedToNull.

@MapFeature.Require({ SUPPORTS_PUT, ALLOWS_NULL_VALUES })
@CollectionSize.Require(absent = ZERO)
public void testMappedToNull() {
    initMapWithNullValue();
    assertEquals("Map.merge(keyMappedToNull, value, function) should return value", v3(), getMap().merge(getKeyForNullValue(), v3(), (oldV, newV) -> {
        throw new AssertionFailedError("Should not call merge function if key was mapped to null");
    }));
    expectReplacement(entry(getKeyForNullValue(), v3()));
