‘No JUnit tests found’ in Eclipse

The run configuration for a test class can create another cause (and solution) for this problem.

If you go to Run (or Debug) Configurations (using cmd-3 or clicking on the small dropdown buttons in the toolbar) you can see a configuration created for every test class you’ve worked with. I found that one of my classes that wouldn’t launch had a run configuration where the Test Method field had somehow gotten inadvertently populated. I had to clear that to get it to work. When cleared it shows (all methods) in light text.

I’ll add that strangely — maybe there was something else going on — it also seemed not to work for me until I fixed the “Name” field as well so that it included only the class name like the other JUnit run configurations.

“No JUnit Tests Found” Error Solution

1. Introduction

One of the first steps that developers take in order to create Unit Test case is to ensure that their environment is ready. This means that all required libraries are setup properly and that the JUnit Test cases are correctly annotated. There might be a couple of technical hiccups like proper source folder configuration in your specific IDE, but regardless, this issues shouldn’t be a roadblock to begin with.

2. Issue: No Junit Tests Found

Developers might encounter issues along the way of setting up their test case. I myself have encountered a lot of issues before I even get my maven project building successfully. For this particular post, I will discuss how to resolve the “No JUnit Test Found” error.

3. Solution

3.1 Library setup

We need to ensure that our project has the correct dependencies or libraries. Legacy projects that do not use maven dependencies often need to import their libraries manually. This manual way of doing it is prone to inconsistent configurations and might lead to more erroneous setup. Convert your project to maven. Invest on converting your project to a full blown maven configured project.

Using maven will really get some of those setup in tact and you’ll never have to worry about missing any dependencies again.

pom.xml

4.0.0 com.areyes1.jgc.itest junit-no-test-found 0.0.1-SNAPSHOT junit junit 4.12 test

In Eclipse, the libraries will be represented as a maven dependency as shown below.

By default this is implicitly called. When an annotated method ( @Test ) is detected, it automatically calls as default runner for that entire class. If the issue persists though, you can explicitly indicate it on your class, just like the one below:

JUnitTestingSampleNoTestFound.java

package com.areyes1.jgc.no.tests; import static org.junit.Assert.assertFalse; import org.junit.Before; import org.junit.Test; import org.junit.runner.RunWith; import org.junit.runners.JUnit4; @RunWith(JUnit4.class) public class JUnitTestingSampleNoTestFound { int totalNumberOfApplicants = 0; int totalNumberOfAcceptableApplicants = 10; @Test public void testAssertFalseWithMessage() { assertFalse( “Is total number of applicants acceptable?”, (this.totalNumberOfApplicants != this.totalNumberOfAcceptableApplicants)); } }

This might not be the case all the time and I think any java developer would figure out what’s wrong before they even reach this page. The @Test annotation is a crucial piece of configuration for the JUnit Test case. It marks the method as a JUnit Test case.

testInvoke()

@Test public void testInvoke() { assertFalse( “Is total number of applicants acceptable?”, (this.totalNumberOfApplicants != this.totalNumberOfAcceptableApplicants)); }

3.4 All else fail? Just clean up your workspace and make sure all configurations are set.

I’ve seen and heard many stories of how they encounter this error. Some suggests that the best solution is to restart your IDE. But I do think it’s just that. When you restart your IDE, the whole configuration will be refreshed automatically, and this might be the solution to that problem you’re encountering while running JUnit Test case!

Eclipse No tests found using JUnit 5 caused by NoClassDefFoundError for LauncherFactory

The problem

Whenever I run my projects JUnit test (using JUnit 5 with Java 9 and Eclipse Oxygen 1.a) I encounter the problem that eclipse can’t find any tests.

The description

Under the run configuration, eclipse can’t even find the method which is annotated with @Test, but instead only shows me “(all methods)”. The following picture hopefully gives a better glimps of my setup:

What I tried so far

I’ve already tried

to remove the test folder from build path and add it again.

to start the test with hovering over the method annotated with @Test and then click “Run as JUnit Test”.

remove JUnit from Buildpath and add it again

restart eclipse

I’ve also moved the project whole project from one machine to another machine and tried it with the provided eclipse installation there

to rename the test method.

to retype the @Test annotation

Some of these steps can be found here, but in the end the problem remained.

How to set up JUnit in Eclipse

Many versions of Eclipse will come with JUnit already included. Versions not meant for Java may not, however. When Eclipse is opened, a quick check to see if JUnit was included is to go to:

File -> New -> JUnit Test Case

If this option is there, JUnit was included. If not, you can instead select:

Help -> Install New Software

within Eclipse. In the Work with: field, your Eclipse version should have a Site entry in the dropdown, such as:

http://download.eclipse.org/releases/luna/201406250900

Once you choose this, you can then navigate to:

Programming Languages -> Eclipse Java Development Tools

in the table below and select that option.

Once you installed the JUnit software, you can start creating tests for your Java classes, such as by going to:

New->JUnit Test Case

on a .java file’s context menu in Package Explorer.

Once you fill in the Unit test information, the test class location, and create test methods, you will most likely see prompts to Add JUnit 4 library to the build path.

Then, you can run the application with JUnit:

Run -> Run As -> JUnit Test

after selecting the app in Package Explorer.

Your test results will then display with run duration, errors, failures, failure traces, console output, and visual indicators.

JUnit – Frequently Asked Questions

Create a class: package junitfaq; import org.junit.*; import static org.junit.Assert.*; import java.util.*; public class SimpleTest { Write a test method (annotated with @Test ) that asserts expected results on the object under test: @Test public void testEmptyCollection() { Collection collection = new ArrayList(); assertTrue(collection.isEmpty()); } If you are running your JUnit 4 tests with a JUnit 3.x runner, write a suite() method that uses the JUnit4TestAdapter class to create a suite containing all of your test methods: public static junit.framework.Test suite() { return new junit.framework.JUnit4TestAdapter(SimpleTest.class); } Although writing a main() method to run the test is much less important with the advent of IDE runners, it’s still possible: public static void main(String args[]) { org.junit.runner.JUnitCore.main(“junitfaq.SimpleTest”); } } Run the test: To run the test from the console, type: java org.junit.runner.JUnitCore junitfaq.SimpleTest

To run the test with the test runner used in main() , type: java junitfaq.SimpleTest The passing test results in the following textual output: . Time: 0 OK (1 tests) [top]

(Submitted by: Jeff Nielsen) A test fixture is useful if you have two or more tests for a common set of objects. Using a test fixture avoids duplicating the code necessary to initialize (and cleanup) the common objects. Tests can use the objects (variables) in a test fixture, with each test invoking different methods on objects in the fixture and asserting different expected results. Each test runs in its own test fixture to isolate tests from the changes made by other tests. That is, tests don’t share the state of objects in the test fixture. Because the tests are isolated, they can be run in any order. To create a test fixture, declare instance variables for the common objects. Initialize these objects in a public void method annotated with @Before . The JUnit framework automatically invokes any @Before methods before each test is run. The following example shows a test fixture with a common Collection object. package junitfaq; import org.junit.*; import static org.junit.Assert.*; import java.util.*; public class SimpleTest { private Collection collection; @Before public void setUp() { collection = new ArrayList(); } @Test public void testEmptyCollection() { assertTrue(collection.isEmpty()); } @Test public void testOneItemCollection() { collection.add(“itemA”); assertEquals(1, collection.size()); } } Given this test, the methods might execute in the following order: setUp() testEmptyCollection() setUp() testOneItemCollection() The ordering of test-method invocations is not guaranteed, so testOneItemCollection() might be executed before testEmptyCollection() . But it doesn’t matter, because each method gets its own instance of the collection . Although JUnit provides a new instance of the fixture objects for each test method, if you allocate any external resources in a @Before method, you should release them after the test runs by annotating a method with @After . The JUnit framework automatically invokes any @After methods after each test is run. For example: package junitfaq; import org.junit.*; import static org.junit.Assert.*; import java.io.*; public class OutputTest { private File output; @Before public void createOutputFile() { output = new File(…); } @After public void deleteOutputFile() { output.delete(); } @Test public void testSomethingWithFile() { … } } With this test, the methods will execute in the following order: createOutputFile() testSomethingWithFile() deleteOutputFile() [top]

(Submitted by: Dave Astels) Often if a method doesn’t return a value, it will have some side effect. Actually, if it doesn’t return a value AND doesn’t have a side effect, it isn’t doing anything. There may be a way to verify that the side effect actually occurred as expected. For example, consider the add() method in the Collection classes. There are ways of verifying that the side effect happened (i.e. the object was added). You can check the size and assert that it is what is expected: @Test public void testCollectionAdd() { Collection collection = new ArrayList(); assertEquals(0, collection.size()); collection.add(“itemA”); assertEquals(1, collection.size()); collection.add(“itemB”); assertEquals(2, collection.size()); } Another approach is to make use of MockObjects. A related issue is to design for testing. For example, if you have a method that is meant to output to a file, don’t pass in a filename, or even a FileWriter . Instead, pass in a Writer . That way you can pass in a StringWriter to capture the output for testing purposes. Then you can add a method (e.g. writeToFileNamed(String filename) ) to encapsulate the FileWriter creation. [top]

Unit tests are intended to alleviate fear that something might break. If you think a get() or set() method could reasonably break, or has in fact contributed to a defect, then by all means write a test. In short, test until you’re confident. What you choose to test is subjective, based on your experiences and confidence level. Remember to be practical and maximize your testing investment. Refer also to “How simple is ‘too simple to break’?”. [top]

(Submitted by: J. B. Rainsberger) Most of the time, get/set methods just can’t break, and if they can’t break, then why test them? While it is usually better to test more, there is a definite curve of diminishing returns on test effort versus “code coverage”. Remember the maxim: “Test until fear turns to boredom.” Assume that the getX() method only does “return x;” and that the setX() method only does “this.x = x;”. If you write this test: @Test public void testGetSetX() { setX(23); assertEquals(23, getX()); } then you are testing the equivalent of the following: @Test public void testGetSetX() { x = 23; assertEquals(23, x); } or, if you prefer, @Test public void testGetSetX() { assertEquals(23, 23); } At this point, you are testing the Java compiler, or possibly the interpreter, and not your component or application. There is generally no need for you to do Java’s testing for them. If you are concerned about whether a property has already been set at the point you wish to call getX() , then you want to test the constructor, and not the getX() method. This kind of test is especially useful if you have multiple constructors: @Test public void testCreate() { assertEquals(23, new MyClass(23).getX()); } [top]

Add the optional expected attribute to the @Test annotation. The following is an example test that passes when the expected IndexOutOfBoundsException is raised: @Test(expected=IndexOutOfBoundsException.class) public void testIndexOutOfBoundsException() { ArrayList emptyList = new ArrayList(); Object o = emptyList.get(0); } [top]

Declare the exception in the throws clause of the test method and don’t catch the exception within the test method. Uncaught exceptions will cause the test to fail with an error. The following is an example test that fails when the IndexOutOfBoundsException is raised: @Test public void testIndexOutOfBoundsExceptionNotRaised() throws IndexOutOfBoundsException { ArrayList emptyList = new ArrayList(); Object o = emptyList.get(0); } [top]

Place your tests in the same package as the classes under test. Refer to “Where should I put my test files?” for examples of how to organize tests for protected method access. [top]

Testing private methods may be an indication that those methods should be moved into another class to promote reusability. But if you must… If you are using JDK 1.3 or higher, you can use reflection to subvert the access control mechanism with the aid of the PrivilegedAccessor. For details on how to use it, read this article. If you are using JDK 1.6 or higher and you annotate your tests with @Test, you can use Dp4j to inject reflection in your test methods. For details on how to use it, see this test script. [top]

(Submitted by: J. B. Rainsberger) Reporting multiple failures in a single test is generally a sign that the test does too much, compared to what a unit test ought to do. Usually this means either that the test is really a functional/acceptance/customer test or, if it is a unit test, then it is too big a unit test. JUnit is designed to work best with a number of small tests. It executes each test within a separate instance of the test class. It reports failure on each test. Shared setup code is most natural when sharing between tests. This is a design decision that permeates JUnit, and when you decide to report multiple failures per test, you begin to fight against JUnit. This is not recommended. Long tests are a design smell and indicate the likelihood of a design problem. Kent Beck is fond of saying in this case that “there is an opportunity to learn something about your design.” We would like to see a pattern language develop around these problems, but it has not yet been written down. Finally, note that a single test with multiple assertions is isomorphic to a test case with multiple tests: One test method, three assertions: public class MyTestCase { @Test public void testSomething() { // Set up for the test, manipulating local variables assertTrue(condition1); assertTrue(condition2); assertTrue(condition3); } } Three test methods, one assertion each: public class MyTestCase { // Local variables become instance variables @Before public void setUp() { // Set up for the test, manipulating instance variables } @Test public void testCondition1() { assertTrue(condition1); } @Test public void testCondition2() { assertTrue(condition2); } @Test public void testCondition3() { assertTrue(condition3); } } The resulting tests use JUnit’s natural execution and reporting mechanism and, failure in one test does not affect the execution of the other tests. You generally want exactly one test to fail for any given bug, if you can manage it. [top]

JUnit 3.7 deprecated assert() and replaced it with assertTrue() , which works exactly the same way. JUnit 4 is compatible with the assert keyword. If you run with the -ea JVM switch, assertions that fail will be reported by JUnit. [top]

Refactoring J2EE components to delegate functionality to other objects that don’t have to be run in a J2EE container will improve the design and testability of the software. Cactus is an open source JUnit extension that can be used to test J2EE components in their natural environment. [top]

(Submitted by: J. B. Rainsberger) No. It is a convention to start with one test class per class under test, but it is not necessary. Test classes only provide a way to organize tests, nothing more. Generally you will start with one test class per class under test, but then you may find that a small group of tests belong together with their own common test fixture.[1] In this case, you may move those tests to a new test class. This is a simple object-oriented refactoring: separating responsibilities of an object that does too much. Another point to consider is that the TestSuite is the smallest execution unit in JUnit: you cannot execute anything smaller than a TestSuite at one time without changing source code. In this case, you probably do not want to put tests in the same test class unless they somehow “belong together”. If you have two groups of tests that you think you’d like to execute separately from one another, it is wise to place them in separate test classes. [1] A test fixture is a common set of test data and collaborating objects shared by many tests. Generally they are implemented as instance variables in the test class. [top]

(Submitted by: Eric Armstrong) The following templates are a good starting point. Copy/paste and edit these templates to suit your coding style. SampleTest is a basic test template: import org.junit.*; import static org.junit.Assert.*; public class SampleTest { private java.util.List emptyList; /** * Sets up the test fixture. * (Called before every test case method.) */ @Before public void setUp() { emptyList = new java.util.ArrayList(); } /** * Tears down the test fixture. * (Called after every test case method.) */ @After public void tearDown() { emptyList = null; } @Test public void testSomeBehavior() { assertEquals(“Empty list should have 0 elements”, 0, emptyList.size()); } @Test(expected=IndexOutOfBoundsException.class) public void testForException() { Object o = emptyList.get(0); } } [top]

[FIXED] ‘No JUnit tests found’ in Eclipse

Issue

So I’m new to JUnit, and we have to use it for a homework assignment. Our professor gave us a project that has one test class, BallTest.java . When I right click > Run as > JUnit Test, I get a popup error that says ‘No JUnit tests found’. I know the question has been answered here(No tests found with test runner ‘JUnit 4’), but closing eclipse, restarting, cleaning, and building doesn’t seem to work.
