java.lang.NoClassDefFoundError when running Android JUnit test
Got it. The problem was that Android dependencies in my Client project were not being updated. This prevented classes from being added to build path. Steps to solve the issue: Right Click on Android Dependencies in the Client Project > Build Path > Remove from Build Path. Right Click on the Client Project > Android Tools > Fix Project Properties.

Running Android JUnit tests with Ant: ClassNotFoundException: org.junit.Test
The JUnit task page lists several ways in which you can make the JUnit jar available to Ant: http://ant.apache.org/manual/Tasks/junit.html In particular, option 1 would require adding both "junit.jar" and "ant-junit.jar" to "ANT_HOME/lib". Any of the 5 options listed there should work just fine though.

Android Studio JUnit pure Java tests
How about the gradle android test plugin? ("A Gradle plugin which enables good 'ol fashioned unit tests for Android builds." sounds like what you want) Or maybe something like robotium / roboelectric.

Running simple JUnit tests on Android Studio (IntelliJ) when using a Gradle-based configuration
Normally, you can't. Welcome to the world of Android, where all tests must run on a device(except Robolectric). The main reason is that you don't actually have the framework's sources - even if you convince the IDE to run the test locally, you will immediately get a "Stub! Not implemented" exception. "Why?" you might wonder? Because the android.jar that the SDK gives you is actually all stubbed out - all the classes and methods are there but they all just throw an exception. It's there to provide an API but not there to give you any actual implementation. There's a wonderful project called Robolectric which implements a lot of the framework just so you can run meaningful tests. Coupled with a good mock framework (e.g., Mockito), it makes your job manageable. Gradle plugin: https://githu

jUnit tests work in Eclipse, but fail in ant - java.lang.RuntimeException: Stub
The problem occurs when the android.jar is referenced before the junit.jar in the classpath. In your build.xml, the order seems correct, but you specified the id with a space in it: <path id="JUnit 4.libraryclasspath"> You should use ids without spaces or other special characters (.-_ are ok, though). The stacktrace in your UPD1 shows no junit, which is another indication for a missing lib.

Exception in thread "main" java.lang.NoClassDefFoundError in AWS Elastic Map Reduce
The 3rd party dependency isn't included in the job jar by default and hence the error message you are seeing. It works in Eclipse standalone mode as Eclipse knows to add the jar to the classpath at execution time. You have two choices: Unpack this jar and repack your classes and the 3rd party dependency jars into a single 'uber' or monolithic jar - maven has a jar-with-dependencies assembly for doing this (if you're using maven, which i'd personally recommend) Use the -libjars argument combined with the ToolRunner method for submitting jobs - this will ensure your 3rd party jars are submitted with your job hadoop jar myJar.jar -libjars ejml.jar MainClass.class

How to run a JUnit Test in android studio?
I think this is not possible if you only have the Android plugin in your build.gradle. The only testing that is supported in the Android plugin is in the InstrumentTest folder. The normal test folder is only used by other plugins. Next to that there is probably support needed in Android Studio itself. But not sure about that.

organising junit tests that expect an exception
If they are completely independent then write independent tests, but if they are closely related (looks like it) then just have a single test with the four calls, each call wrapped in a try-catch, and a fail('exception expected') after each call. As it was done in junit 3.

How can I convert these JUnit 3 tests to JUnit 4?
The very first thing I would do is try to convince whomever gave me the task that it is unnecessary. I know that is hard as an intern, but it is worth making sure that person understands this isn't necessary. Facts for convincing: The JUnit 4 jar contains both the junit.framework and org.junit package structures so it is backward compatible. JUnit has broad adoption. They owners of the JUnit project are well aware of this and aren't going to ask people to rewrite all the tests. In other words, they aren't going to just drop compatibility. Actually try it. Seriously. Try running your existing test code as is with the JUnit 4 jar. You'll see if you get any compiler errors. If you do, those are the areas to focus. If you don't, you have great evidence to show to the person who gave

NullPointerException when running JUnit tests, saying interface is null
You never initialize the filter field in the test class NoiseFilter filter; SensorData dataSet; @Before public void setUp() throws Exception { this.dataSet = new SensorData(); dataSet.setFilter(filter); } so it is null here and that reference propagates to the SensorData object you are testing. public void setFilter(NoiseFilter filterVar) { this.filter = filterVar; } filterVar is null when you call the above. You have to initialize it with an implementation of your interface, such as your AveragingFilter: @Before public void setUp() throws Exception { this.filter = new AveragingFilter(); // or something like it this.dataSet = new SensorData(); dataSet.setFilter(filter); } Also, you are testing for null in a few places using this pattern: if( x.equals(

You can't run the tests for multiple projects in Eclipse, at least using the normal runners. There are, however a number of options: Create an ant/maven script which runs everything If you want to run your tests every time you save, you can use Infinitest. From the site of Infinitest: Infinitest is a Continuous Testing plugin for Eclipse and IntelliJ. Each time a change is made on the source code, Infinitest runs all the tests that might fail because of these changes. Infinitest can potentially run all of the tests in all projects.

deep within JUnit Parameterized test runner: java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to java.util.List
In the example given for JUnit (which your Javadoc links to), the method annotated @Parameters returns Collection<Object[]>, presumably where each Object[] is an array of arguments to be passed to the test case's constructor via Constructor.newInstance. Your return value from data() should be a Collection<Object[]> instead of just Object[]; I think you need to have an argument-taking constructor for ExpectNoAltTagsInSellerNamesTest, but the JUnit docs are lacking.

Exception in thread "main" java.lang.NoSuchMethodError:
Now that you have updated your answer with your "build.sbt" file, it is rather clear what is happening: your application has "org.scalaj" % "scalaj-http_2.9.2" % "0.3.7" as a dependency. You are forcing the scala version for "scalaj", meaning that you will (transitively) get scala 2.9.2 pulled in your classpath, in addition to scala 2.10.2. To avoid this, do not force the scala version in your dependencies, but let sbt infer it from your project's scala version, by using the %% operator instead of % (just like you did for your other dependencies): "org.scalaj" %% "scalaj-http" % "0.3.9" Note that I have upgraded the library version to 0.3.9 as it is apparently the first version to be available for scala 2.10.

Running JUnit tests that depend on resources defined in WebSphere
though not connecting to the WebSphere instance, when looking at JNDI resources, you can always use SimpleNamingContextBuilder from the org.springframework.mock.jndi package. This allows you to build an object (say a DataSource with your own direct binding to the remote JNDI service) then bind it to a 'mock' JNDI service for injection into the Spring Application Context at test time. to do this, you'll need to do it in the @BeforeClass (static) of a JUnit Test to ensure that the JNDI bindings are available before the App context starts up. (so the App context can find something when it looks up jdbc/dataSource) i wouldn't recommend connecting another server if you're going to use this in a Continuous Integration environment, but if you're looking at doing just a 'one-off, manual test'

Yes, you are right. You need to import google_play_services_lib and add it as a library to your project. For this, you need to: Download the Google Play Services from the Android SDK manager Add this as a project by "Importing existing Android Code Base". Go to ~/<android_sdk>/extras/google/google_play_services/libproject and add this to your workspace. Once this project has been added to your workspace, right-click on it, go to "Properties" and then to "Android" tab and mark it as a library. Go to your application, and then right-click to go to the "Properties" and go to the "Android" tab and in the Library pane, click "Add Library". This should show you the google_play_services project. Add this as a reference to your project. Another requirement is to right-click on your proj

Exception in thread "main" java.lang.NullPointerException - Package
System.console can return null depending on the environment in which the JVM is operating. From the javadoc If no console device is available then an invocation of that method will return null. Eclipse is one of these environments where the System.console returns null since it typically uses javaw which doesnt have an associated console window. Use java.util.Scanner instead which has no such limitation. Scanner scanner = new Scanner(System.in); String planet = scanner.nextLine();

If you observe, now you can start from 0 (or) 1 (or) 2, but max you can go upto a[4] only, when you use in <=, loop will check until a[5] which throws indexoutofBounds exception.
