为什么摩卡交易的测试结果是错误的，但它在 REST 测试中工作正常？

Question

我在 hyperledger-fabric 中写了一个事务，并在 mocha 上为它实现了一个测试单元。交易应设置资产的标题属性。在我使用 assetRegistry.updade 函数更新后，资产标题值没有改变，但是当我在 REST 中测试时它工作正常。

CTO 文件

transaction TestOnChat {
  --> Chat chat
}

asset Chat identified by chatId {
  o String chatId
  o String title
  o DateTime createAt
  o ChatType type
  o Member[] memberList
  o Message[] messageList
}

permissions.asl

rule Test{
    description: "Member can expel other member chat"
    participant: "org.miluxas.chatnet2.User"
    operation: ALL
    resource: "org.miluxas.chatnet2.TestOnChat"
    action: ALLOW
}

logic.js

/**
 * 
 * @param {org.miluxas.chatnet2.TestOnChat} testOnChat - the teropooo
 * @transaction
 */
async function testOnChat(ex){

    ex.chat.title='fdfdfdf';
    const memberRegistry = await getAssetRegistry('org.miluxas.chatnet2.Chat');
    await memberRegistry.update(ex.chat);
}

test/logic.js

it('test chat', async () => {
    // Use the identity for Solivan.
    await useIdentity(solivanCardName);

    await createNewChat('32556','first solivan group chat','PUBLIC_GROUP');

    // Get the asset. and check if Ferzin added to chat
    const assetRegistry = await businessNetworkConnection.getAssetRegistry('org.miluxas.chatnet2.Chat');
    const asset1 = await assetRegistry.get('32556');

    // Submit add other user to chat transaction
    const transaction33 = factory.newTransaction(namespace, 'TestOnChat');
    transaction33.chat = factory.newRelationship(namespace, 'Chat', '32556');
    await businessNetworkConnection.submitTransaction(transaction33);

    //console.log(asset1.type);
    asset1.title.should.equal('fdfdfdf');
});

我在 test/logic.js 中发现了我的错误。我在提交TestOnChat transaction之前设置了asset1，提交交易后检查了
