问题描述
我正在尝试测试我的控制器 - Secure.java.我使用 play 的 Fixtures 类来设置数据库.不幸的是，当发出 POST 调用并调用控件的方法时，数据库结果是空的.但是，在测试方法中，我可以按预期检索数据.
I am trying to test my Controller - Secure.java. I use play's Fixtures class to setup the database. Unfortunately as the POST call is issued and the control's method is called the database turns out to be empty. However, inside the test-method I can retrieve the data as expected.

推荐答案
您的功能测试在一个事务中运行，该事务将在测试结束时结束.因此，在测试完成之前，您在此事务中所做的一切都不会提交到数据库.因此，在这种情况下，您可以使用作业为设置创建新事务
Your functional test run in a transaction that will end at the end of the test. So everything you do in this transaction won't be commited to the database until the test is finished. So in this case you can use a job to create a new transaction only for the setup
@Before
public void setUp() throws Exception {
new Job() {
@Override
public void doJob() throws Exception {
Fixtures.deleteDatabase();
Fixtures.loadModels("testusers.yaml");
Cache.clear();
}
}.now().get();
}
