Coding Standards


  1. Redundant modifiers on interface method declarations

Chapter 9.4 of the Java Language Specification states: It is permitted, but discouraged as a matter of style, to redundantly specify the public and/or abstract modifier for a method declared in an interface.

Utility Classes

In order to optimize reuse of code, OSEE developers have adopted a set of standards.

Utility classes should:

  1. Be named xxxUtil. This allows for each searching and location by looking for *Util. This excludes stand-alone utility classes like HashCollection or CountingMap.
  2. As much as possible, be located in a package postfix'd with .util. eg. org.eclipse.osee.ats.util
  3. Should contain static methods

Cleanup of existing utility methods

The following needs to be done:

  1. Create set of common utility class names
  2. Move utilities to their respective places
  3. Either deprecate or replace uses of old locations


Most comments offer more clutter than information, especially non-Javadoc comments which can be removed using the following regular expression \R[ \t]*/\*\s+[\* ]*\(non-Javadoc\)[^/]+/.

Regular Expression Find/Replace application of standards

  • ([^ ]+) != null && !(\1).equals\(""\) replace with Strings.isValid($1)
  • ([^ ]+) == null \|\| (\1).equals\(""\) replace with !Strings.isValid($1)

REST API Documentation

Jersey and Javadoc supported tags in the code are processed during the maven compile phase to create an enhanced application.wadl file. The enhancements include extra documentation pulled from the source. The following set of tags should be used so a consistant set of documentation is available for all REST interfaces.


  1. Every class implementing REST methods should use an @Path tag even if the paths is empty (e.g. @Path("") ).
  2. All parameters should be tagged with the appropriate @xxxParam tag (e.g. @PathParam, @QueryParam, etc.).
  3. The @Consumes tag should be used as appropriate for methods that take in data.
  4. The @Produces tag should be used as appropriate for methods returning information.

Javadoc Tags

  1. Use the '@param name description' for every parameter in the method. The 'name' needs to match the method paramater name
  2. Use the '@return description' as appropriate

The Jersey wadl generator supports additional tags for documenting request and response information.

  1. Use the ' description' for all valid responses from the method
  2. Use the ' type' when the media type is different than specified in @Produces


public class TakeAREST {
	 * Find a great RESTing place for your resources
	 * @param place The ideal spot to look for RESTing
	 * @return The best RESTing spot available
	 * @response.representation.200.doc found the spot for you
         * @response.representation.503.doc RESTing places are currently unavailable.  Try again later.
	@Produces({"application/xml", "application/json"})
	public String getPlaceToREST(@QueryParam("place") String place) {
		return "RESTing Place";
	 * Store a RESTing spot for others to find and use
	 * @param spot Just a good spot for RESTing
	 * @return Acknowledging the location of the RESTing spot
	 * @response.representation.200.doc This is a good spot
	 * @response.representation.404.doc Wasn't able to create the shared RESTing spot
	 * @response.representation.404.mediaType plain/txt
	public RestReturn createRESTingSpot(@PathParam("spot") String spot) {
		RestReturn myRet = new RestReturn();
		myRet.setName("A Great Name");
		return myRet;

OSEE Master Test Suite

OSEE uses JUnit 4 for its test suites. Some links to get started:

Use Cases

Requirements of the OSEE test suite:

  1. Single button press to run all tests
  2. Minimal number of launch configurations to maintain
  3. Ability for any user, internal or external, to easily run a suite of tests before commit
  4. Continuous integration (checkout, build, test, report)
  5. Use JUnit framework for all testing
  6. Enable health checks against production database to be part of test suite
  7. New test cases can be added easily

Running the OSEE Test Suite

The OSEE test suite uses the org.eclipse.osee.ats.config.demo plugin to initialize a demo database, populate it with demo data and run the majority of the OSEE tests against this common data set.

These tests are contributed to the MasterTestSuite groups using Eclipse's extension point framework. Any Test Suite can implement IOseeTest and extend the OseeTest extension point to be contributed to the appropriate test suite(s).

Steps to test

  1. Checkout org.eclipse.osee.ats.config.demo
  2. Checkout
  3. Run the following tests in order and resolve any errors:
    1. Run the Demo database tests:
      1. Run the OSEE Demo Application Server launch config
      2. Run the MasterTestSuite_DemoDbInit launch config. This initializes the postgres database for demo populate and tests
      3. Run the MasterTestSuite_DemoDbPopulate launch config. This loads the database with branches, actions and sets conditions for populate tests.
      4. Run the MasterTestSuite_DemoDbTests launch config. This runs tests against the DemoDb Populated database.
      5. Stop the OSEE Demo Application Server if still running
    2. Run the Production TestDb tests:
      1. Run the OSEE Application Server launch config.
      2. Run the MasterTestSuite_TestDbInit launch config. This initializes the postgres database for production testdb tests
      3. Run the MasterTestSuite_TestDbTests launch config. - This runs production specific tests using a TestDb.
    3. Run the Production tests and health checks against the current production release
      1. Run the MasterTestSuite_ProductionTests launch config. This runs tests and health checks against the current production released database.

Common test utility plugin

The plugin is in support of our testing framework. It has a number of common enums and a TestUtil class that should be used by any junit tests. The intent is to keep this plugin lightweight and without many dependencies cause all the testing fragments "should" include it. In addition, it should not be included by any production plugins, only test fragments.

Adding new Tests to MasterTestSuite

To create test fragment off plugin to be tested

All OSEE JUnit tests should live in a fragment of the plugin to be tested.

  1. Select plugin to be tested
  2. Right-click -> New Project -> Plugin Project -> Plugin Fragment
  3. Enter plugin to be tested as Host plugin
  4. Complete wizard
  5. In plugin to be tested (eg org.eclipse.osee.ats)
    1. Add "Eclipse-ExtensibleAPI: true" to MANIFEST.MF of plugin to be tested. This allows test suites to see tests in this plugin
  6. In new fragment (eg org.eclipse.osee.ats.test)
    1. Add org.junit4 (make sure junit4, not junit) to dependencies
    2. Add the common test utility plugin plugin to dependencies
    3. Export packages containing TestCases and TestSuites
  7. In MasterTestSuite plugin (eg
    1. Add dependency on plugin to be tested (ge org.eclipse.osee.ats)
    2. Add test cases and suites from fragment to appropriate MasterTestSuite java Test Suites

To add a new JUnit TestCase

  1. Write the TestCase to run against a database populated with DemoDbInit and DemoDbPopulate
  2. Add the TestCase to an existing MasterTestSuite_DemoDbTests test suite

Things to consider

  1. Your tests must clean-up after themselves to ensure that the entire test suite can be run.
  2. Do not assume order of execution except within your own Test Suite

Master Test Suite - Frequently Asked Questions

What do I need for every test case?

  • import static org.junit.Assert.*;
  • In setup method (@Before), always assert that you are on correct database by adding one of these
assertTrue("Should be run on production datbase.", TestUtil.isProductionDb());
assertTrue("Should be run on test datbase.", TestUtil.isTestDb());
assertTrue("Should be run on demo datbase.", TestUtil.isDemoDb());
  • In setup method (@Before), always assert that you have correct app server running *
assertTrue("Demo Application Server must be running.",
assertTrue("Client must authenticate using demo protocol",
assertFalse("Application Server must be running.",
assertFalse("Client can't authenticate using demo protocol",

Why do I get an exception on synchronized-lock when I launch the tests

The launch configuration does not have all plugins necessary to run.

  1. Open Debug Configurations for that launch item
  2. Go to plugins tab and select "Validate Plugins". This will show if any plugins are missing from selected items.
  3. Select "Add Required Plugins" to add them.
  4. Re-launch.

Why do I get exceptions that cycle was detected when I add things to the org.eclipse.osee.test.util plugin

This plugin is meant to be extremely light-weight and only provide simple statics and methods to all the test plugins. Because it has to be included in all test fragments from jdk.core all the way up to framework.ui (skynet.ui), it can not depend on any of the higher level plugins or cycles will occur. Remove these dependencies and cycles will be fixed.

How do I timeout a test?

Define a timeout period in miliseconds with “timeout” parameter. The test fails when the timeout period exceeds. view

@Test(timeout = 1000)  
public void infinity() {  
    while (true);  

How do I test exception handling

Exception Handling Use “expected” paramater with @Test annotation for test cases that expect exception. Write the class name of the exception that will be thrown. view plainprint?

@Test(expected = ArithmeticException.class)  
public void divisionWithException() {  
   // divide by zero  
   simpleMath.divide(1, 0);  

To add a new JUnit TestSuite

  1. Create a fragment for the plugin (see above)
  2. Create new JUnit TestCases as above
  3. Create a new JUnit TestSuite
  4. Add new TestSuite to one of the MasterTestSuite java test suites

Common test cases

import org.junit.After;
import org.junit.AfterClass;
import org.junit.Assert;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
 * @link <link_to_class_under_test>
 * @author <you>
public final class MySuperbTest {
   private static SevereLoggingMonitor monitorLog = null;
   private static Artifact myRootArtifact = null;
   public void importSimpleArtifacts() throws Exception {
      Assert.assertTrue("Some message...", conditionToBeTrue);
   public void setUp() throws Exception {
      /* some pre init stuff before each case */
   public void tearDown() throws Exception {
      /* useful to destroy any artifacts after your test */
      new PurgeArtifacts(myRootArtifact.getChildren()).execute();
      /* example how you would wrap one element to pass in */
      new PurgeArtifacts(Collections.singletonList(myRootArtifact)).execute();
   public static void setUpOnce() throws Exception {
      monitorLog = TestUtil.severeLoggingStart();
   public static void tearDownOnce() throws Exception {
      /* any other final cleanup */


  • OSGi is a set of specifications that define a dynamic component system for Java where an application is composed of several components which are packaged in bundles. Components communicate locally and across the network through services.
  • Singleton bundles
A singleton bundle is used to prevent any other version of a bundle being loaded in memory, there can be only one resolved version in the run time at any point. The use of a singleton bundle can be desirable where access to a single system resource is required from a set of applications. Use this option for test fragments.

GUI using RAP

  • The term "RAP client" is used to identify the software that displays the actual UI of a RAP application and communicates with the RAP server using the RAP Protocol.
  • The RAP Protocol is JSON-based message format that fully decouples the RAP server and client with the intention of making the client exchangeable.
  • The default RAP client is written in JavaScript and is downloaded and started automatically when a browser accesses the URL of a RAP application.

Excellent Sources

Two alternative learning sources:


  • Collections.synchronizedMap still requires manual synchronization on the returned map when iterating over any of its collection views.
  • Eclipse -> Debug Perspective -> Debug view (stacktrace view) -> white downward arrow menu -> Java -> Show Monitors
Eclipse can detect deadlocks and gives locking information needed to determine the root cause
  • When using a HashMap with more than one thread, use java.util.concurrent.ConcurrentHashMap instead

Rebaselining a development branch onto master

 Note: Replace all references to /c/x/git/x with your git reop's parent folder
  1. prerequisite: master is pointing to tip of most recent next release branch otherwise replace references to master with it below
    git pull --rebase
    git push origin head:master
  2. Announce on mailing list commit freeze for source and destination branches
  1. Start rebase using onto
    The following steps apply to org.eclipse.osee and any repositories that depend on it
    To see the work layout before you using Git version 2.19.0 or newer
    git range-diff origin/<previous_stable_version> origin/dev dev
    ensure any Eclipse workspace associated with the repository is closed
    cd /c/x/git/x/org.eclipse.osee; git fetch; git checkout dev
    git reset --hard origin/dev
    remove any untracked files
    git rebase -i --onto origin/master <one commit prior to first commit on dev>
    mark for edit the first commit "refactor: Update build numbers to 0.x.0
  1. Resolve merge conflict of version numbers
    git reset --hard
    Edit to update versions
    vi /c/x/git/x/org.eclipse.osee/plugins/
    Run from repository root
  1. methodically reapply commits
    git rebase --edit-todo
    Select specific commits to edit (aligning with other repositories as needed)
    confirm no compile errors at each selected commit and every few commits run integration tests
    when a compile error or test failure is detected, determine root cause commit and create new FIXUP commit
    git status to check for uncommitted files (one possible cause is a deleted bundle)
    use Import Projects... from Git perspective in Eclipse to import newly added bundles
  1. Cleanup fixup commits
    note current hash of head
    use git rebase -i for second pass of rebase
    move each FIXUP commit to just after the commit it corrects and combine with fixup command
    git diff <previously_noted_hash> head to ensure no unintentional changes
  1. Ensure development branch still builds
    1. Ensure no compile errors in Eclipse workspace
      Launch OSEE dev_alpha install with workspace E:\workspace_nr
      refresh, rebuild, restart
    2. Ensure full Jenkins build succeeds
      git push origin head:user/rebase -f
      build on topic branch
      Wipe Out Workspace first to avoid odd issues building
  2. git rebase --committer-date-is-author-date
  3. git fetch to ensure the commit freeze was not violated
  4. git push origin head:dev -f
