Examples with FieldValue com.google.firebase.firestore.FieldValue used on opensource projects

Example 1 with FieldValue

use of com.google.firebase.firestore.FieldValue in project firebase-android-sdk by firebase.

the class MutationTest method testAppliesLocalServerTimestampTransformsToDocuments.

@Test
public void testAppliesLocalServerTimestampTransformsToDocuments() {
    Map<String, Object> data = map("foo", map("bar", "bar-value"), "baz", "baz-value");
    MutableDocument transformedDoc = doc("collection/key", 1, data);
    Timestamp timestamp = Timestamp.now();
    Mutation transform = patchMutation("collection/key", map("foo.bar", FieldValue.serverTimestamp()));
    transform.applyToLocalView(transformedDoc, /* previousMask= */
    null, timestamp);
    // Server timestamps aren't parsed, so we manually insert it.
    ObjectValue expectedData = wrapObject(map("foo", map("bar", "<server-timestamp>"), "baz", "baz-value"));
    Value fieldValue = ServerTimestamps.valueOf(timestamp, wrap("bar-value"));
    expectedData.set(field("foo.bar"), fieldValue);
    MutableDocument expectedDoc = doc("collection/key", 1, expectedData).setHasLocalMutations();
    assertEquals(expectedDoc, transformedDoc);
}
