Does JUnit execute test cases sequentially?

阅读更多关于 Does JUnit execute test cases sequentially?

问题 In this post, I asked a small question as part of a bigger problem. Since I didn't get responses yet, I put my question here: Is it reasonable to suppose that JUnit executes test cases sequentially: a test case ends befores the next one starts. Does it differ between JUnit versions (my priority is on JUnit4)? And if not, is there a simple way to force JUnit to execute tests sequentially? Thank you 回答1: Yes, by default I believe it runs tests sequentially. JUnit 4.6 introduced an experimental

Easy way to get a test file into JUnit

问题 Can somebody suggest an easy way to get a reference to a file as a String/InputStream/File/etc type object in a junit test class? Obviously I could paste the file (xml in this case) in as a giant String or read it in as a file but is there a shortcut specific to Junit like this? public class MyTestClass{ @Resource(path="something.xml") File myTestFile; @Test public void toSomeTest(){ ... } } 回答1: You can try @Rule annotation. Here is the example from the docs: public static class

问题 My code: @Component public class A { @Autowired private B b; public void method() {} } public interface X {...} @Component public class B implements X { ... } I want to test in isolation class A. Do I have to mock class B? If yes, how? Because it is autowired and there is no setter where i could send the mocked object. 回答1: I want to test in isolation class A. You should absolutely mock B, rather than instantiate and inject an instance of B. The point is to test A whether or not B works, so

Passing JUnit data between tests

阅读更多关于 Passing JUnit data between tests

问题 I just discovered when creating some CRUD tests that you can't set data in one test and have it read in another test (data is set back to its initialization between each test). All I'm trying to do is (C)reate an object with one test, and (R)ead it with the next. Does JUnit have a way to do this, or is it ideologically coded such that tests are not allowed to depend on each other? 回答1: Well, for unit tests your aim should be to test the smallest isolated piece of code, usually method by

AndroidManifest in androidTest directory being ignored

问题 I'm trying to test using the following directory structure (which was setup by Android Studio): I can run some tests just fine, and even the AllTests.java runs fine without the AndroidManifest.xml file even being there. The thing is, for one of my new tests, I need the android.permission.INTERNET permission. So, I added the following to the AndroidManifest.xml file located within the androidTest directory: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com

Can Selenium take a screenshot on test failure with JUnit?

阅读更多关于 Can Selenium take a screenshot on test failure with JUnit?

问题 When my test case fails, especially on our build server, I want to take a picture / screenshot of the screen to help me debug what happened later on. I know how to take a screenshot, but I was hoping for a way in JUnit to call my takeScreenshot() method if a test fails, before the browser is closed. No, I don't want to go edit our bazillions of tests to add a try/catch. I could maybe, just possibly be talked into an annotation, I suppose. All of my tests have a common parent class, but I can
