Spring Boot JPA metamodel must not be empty! when trying to run JUnit / Integration Tests

阅读更多关于 Spring Boot JPA metamodel must not be empty! when trying to run JUnit / Integration Tests

问题 Am using Spring Boot, JUnit 4 & Mockito in a maven based project to tests my Spring Boot Microservice REST API. So, on startup, the DataInserter class loads data from owner.json and cars.json. Normally, via my REST calls, everything works, but it seems I have something wrong with setting up unit tests and integration tests. Project structure: myapi │ ├── pom.xml │ ├── src ├── main │ │ │ ├── java │ │ │ │ │ └── com │ │ │ │ │ └── myapi │ │ │ │ │ ├── MyApplication.java │ │ │ │ │ ├── bootstrap │ │

Unit testing LiveData observerForever results in NullPointer Exception with Junit5

阅读更多关于 Unit testing LiveData observerForever results in NullPointer Exception with Junit5

问题 I am using Android databinding to listen to live data changes and I would like to observe changes on the viewmodel level (Rather then observing on fragment and then sending a callback to the viewmodel) The observerForever is interesting as it serves the purpose for me. However when I run a test I get the following error: java.lang.NullPointerException at androidx.arch.core.executor.DefaultTaskExecutor.isMainThread(DefaultTaskExecutor.java:77) at androidx.arch.core.executor.ArchTaskExecutor

Re-wire spring bean in @Before method

阅读更多关于 Re-wire spring bean in @Before method

问题 I want to unit test an @Controller -annotated class, using JUnit. Is it possible for Spring to reset ("re-wire") the controller to its default injected state ? There would be no problem building a all new controller object. A workaround I found is to set the constructor's visibility to protected and execute ControllerObj controllerObj = new ControllerObj() at the beginning of @Before -annotated class but I obviously do not want to increase contructor's visibility just for testing purpose. 回答1

问题 I have simple unit test which starts my app and tests that certain services have been instantiated. Kind of just a sanity check.

问题 I see there was introduced the new JUnit Jupiter according to JUnit 5 User Guide. JUnit 5 = JUnit Platform + JUnit Jupiter + JUnit Vintage I am confused about the same-named annotations I use across the library. Is there any significant difference between these two ones? org.junit.Test org.junit.jupiter.api.Test The description from the linked page above explains the annotation org.junit.jupiter.api.Test as following: Denotes that a method is a test method. Unlike JUnit 4’s @Test annotation,

Selenium Close File Picker Dialog

阅读更多关于 Selenium Close File Picker Dialog

问题 We are using Selenium-Webdriver on Jenkins box (running linux), to drive Firefox for testing a fairly complex web app. The web app requires the uploading of a photo for testing, and we have achieved that by using sendkeys to the input file dialog. Unfortunately (perhaps due to the way the uploader works, it is plupload and uploads through XHR and not a FORM post) the File Picker Dialog never closes. While this was slightly annoying, in the past the tests still passed fine. Switching from

问题 Here's a BroadcastReceiver from my project, which I'm looking to unit test. When the user makes a phone call, it grabs the phone number, and sets up an intent to start a new activity, passing in the phone number. public class OutgoingCallReceiver extends BroadcastReceiver { @Override public void onReceive(Context xiContext, Intent xiIntent) { if (xiIntent.getAction().equalsIgnoreCase(Intent.ACTION_NEW_OUTGOING_CALL)) { String phoneNum = xiIntent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
