  <a name="Intro"></a><div class="header1">About Metacat Testing</div>
62
  <a name="Overview"></a><div class="header2">Overview</div>
63
  <p>Metacat uses JUnit tests to test its core functionality.  These tests are
64
  good for testing the internal workings of an application, but don't test the 
65
  layout and appearance.  JUnit tests are meant to be one tool in the developer's 
66
  test arsinal. If you are not familiar with JUnit, you should search out some 
67
  tutorial documentation online.  One such tutorial is at 
68
  <a href="http://clarkware.com/articles/JUnitPrimer.html"> The Clarkware JUnit primer</a></p>
69
  
70
  <p>Metacat test cases will need to be run on the same server as the Metacat
71
  instance that you want to test.  Since Metacat and its test cases share the same
72
  configuration files, there is no way to run the tests remotely.</p>
73

    
74
  <a name="MetacatImplementation"></a><div class="header2">JUnit Implementation in Metacat</div>
75
  <p>Metacat test cases are located in the code at:
76
  <div class="code">&lt;workspace&gt;/metacat/test/edu/ucsb/nceas/metacat*/</div>  
77
  There you will find several java files that define JUnit tests.</p>
78
  
79
  <p> Test cases are run via an ant task, and output from the tests appears in 
80
  a build directory.  More on this to follow.</p>
81

    
82
  <a name="WritingTestCase"></a><div class="header1">Writing a Test Case</div>
83
  <a name="Basics"></a><div class="header2">Basics</div>
84
  <p>All you need to do to get your JUnit test included into the Metacat test 
85
  suite is to create it in one of the &lt;workspace&gt;/test/edu/ucsb/nceas/metacat*/
86
  directories.  The ant test tasks will know that it should be run. </p>
87
  
88
  <p> The following methods are required in a test case class:
89
  <ul>
90
    <li>public &lt;Constructor&gt;(String name) - The constructor for the test class. </li>
91
	<li>public void setUp() - Set up any dependencies for the tests.  This is run before each test case.</li> 
92
	<li>public void tearDown() - Release an resources used by the test.</li> 
93
	<li>public static Test suite() - define the test methods that need to be run.</li>
94
	<li>public void initialize() - define any global initializations that need to be done.</li>
95
  </ul>
96
  
97
  You will test for failure using the many assertion methods available.</p>
98
  
99
  <a name="MCTestCase"></a><div class="header2">MCTestCase Base Class</div>
100
  <p>Metacat test cases extend the MCTestCase base class, which holds common 
101
  methods and variables.  Some of these include:
102
  <ul>
103
    <li>SUCCESS/FALURE - boolean variables holding the values for success and failure. </li>
104
	<li>metacatUrl, username, password - connection variables used for LDAP connectivity</li> 
105
	<li>readDocumentIdWhichEqualsDoc() - method to read a document from Metacat server.</li> 
106
	<li>debug() - method to display debug output to standard error.</li>
107
  </ul>
108
  These are just a few examples to give you an idea of what is in MCTestCase.
109
  </p>
110
  
111
  <a name="BestPractices"></a><div class="header2">Best Practices</div>
112
  <p>The following are a few best practices when writing test cases:
113
  <ul>
114
    <li>Extend MCTestCase - Although strictly speaking, it is possible to bypass MCTestCase
115
    and just extend the JUnit TestCase class, you should not do so.   You should always
116
    extend the MCTestCase class.</li>
117
    <li>Extend Multiple Test Methods - Try to strike a balance between the number of test 
118
    methods and the size of each test.  If a test method starts to get huge, you might see
119
    if you can break it down into mulitple tests based on functionality.  If the number of
120
    tests in the test suite starts to get large, you might see if it makes sense to 
121
    separate them out into different test classes.</li>
122
	<li>Use assertion message - Most assertion methods have an alternate implementation that 
123
	includes a message parameter.  This message will be shown if the assertion fails.  You
124
	should use this version of the assertion method.</li> 
125
	<li>debug() - You should use the debug() method available in the MCTestCase class to
126
	display debug output as opposed to System.err.println().  The test configuration will
127
	allow you to turn off debug output when you use the debug() method.</li>
128
  </ul>
129

    
130
  <a name="RunTests"></a><div class="header1">Running Test Cases</div>
131
  <a name="AntTask"></a><div class="header2">Ant task</div>
132
  <p>As we discussed earlier, the test cases run from within ant tasks.  There is a 
133
  task to run all tests and a task to run individual tests. </p>
134
  <p>You will need to have ant installed on your system.  For downloads and instructions,
135
  visit the <a href="http://ant.apache.org/">Apache Ant site</a>.
136
  </p>
137
  <a name="ConfigureMetacat"></a><div class="header2">Configure Metacat For Testing</div>
138
  <p>The test cases will look at the server's metacat properties file for configuration, 
139
  so there are two places that need to be configured.</p>
140
  <p>First, you need to edit the configuration file at:
141
  <div class="code">&lt;workspace&gt;/metacat/test/test.properties</div>
142
  This should only hold one property: metacat.contextDir.  This should point to 
143
  the context directory for the metacat server you are testing.  For example:
144
  <div class="code">metacat.contextDir=/usr/share/tomcat5.5/webapps/knb</div>
145
  The test classes will use this to determine where to look for the server
146
  metacat.properties file.</p>
147
  
148
  <p>the remainder of the configuration needs to happen in the actual server's 
149
  metacat.properties file located at:
150
  <div class="code">&lt;workspace&gt;/metacat/lib/metacat.properties</div>
151
  You will need to verify that all test.* properties are set correctly:
152
  <ul>
153
    <li>test.printdebug - true if you want debug output, false otherwise </li>
154
    <li>test.metacatUrl - the url for the metacat servlet (i.e. http://localhost:8080/knb/metacat)</li>
155
    <li>test.contextUrl - the url for the metacat web service (i.e. http://localhost:8080/knb)</li>
156
    <li>test.metacatDeployDir - the directory where metacat is physically deployed (i.e. /usr/local/tomcat/webapps/knb)</li>
157
    <li>test.mcUser - the first metacat test user ("uid=kepler,o=unaffiliated,dc=ecoinformatics,dc=org" should be fine)</li>
158
    <li>test.mcPassword - the first metacat test password ("kepler" should be fine)</li>
159
    <li>test.mcAnotherUser - the second metacat test user.  This user must be a member of the knb-usr 
160
        group in ldap. ("uid=test,o=NCEAS,dc=ecoinformatics,dc=org" should be fine)</li>
161
    <li>test.mcAnotherPassword - the second metacat test password ("test" should be fine)</li>
162
    <li>test.piscoUser - the pisco test user ("uid=piscotest,o=PISCO,dc=ecoinformatics,dc=org" should be fine)</li>
163
    <li>test.piscoPassword - the pisco test password ("testPW" should be fine)</li>
164
    <li>test.lterUser - the lter test user ("uid=tmonkey,o=LTER,dc=ecoinformatics,dc=org" should be fine)</li>
165
    <li>test.lterPassword - the lter test password ("T3$tusr" should be fine)</li>
166
    <li>test.testProperty - a property to verify that we can read properties (leave as "testing")</li>
167
  </ul>
168
  </p>
169
  
170
  <p>Note that none of the test users should also be administrative users.  This will mess up 
171
  the access tests since some document modifications will succeed when we expect them to fail.</p>
172
  
173
  <p>Once this is done, you will need to rebuild and redeploy the Metacat server.  Note that
174
  changing these properties does nothing to change the way the Metacat server runs.  Rebuilding
175
  and redeploying merely makes the test properties available to the JUnit tests.</p>
176
  
177
  <a name="RunAllTests"></a><div class="header2">Run All Tests</div>
178
  <p>To run all tests, go to the &lt;workspace&gt;/metacat directory and type</p>
179
  <div class="code">ant clean test</div>
180
  You will see a line to standard output summarizing each test result.
181
  </p>
182
  
183
  <a name="RunOneTest"></a><div class="header2">Run One Test</div>
184
  <p>To run one test, go to the &lt;workspace&gt;/metacat directory and type</p>
185
  <div class="code">ant clean runonetest -Dtesttorun=&lt;test_name&gt;</div>
186
  Where &lt;test_name&gt; is the name of the JUnit test class (without .java on 
187
  the end).  You will see debug information print to standard error.
188
  </p>
189
  
190
  <a name="ViewingOutput"></a><div class="header2">Viewing Test Output</div>
191
  <p>Regardless of whether you ran one test or all tests, you will see output in
192
  the Metacat build directory in your code at:
193
  <div class="code">&lt;workspace&gt;/metacat/build</div>
194
  There will be one output file for each test class.  The files will look like 
195
  <div class="code">TEST-edu.ucsb.nceas.&lt;test_dir&gt;.&lt;test_name&gt;.txt</div>
196
  where &lt;test_dir&gt; is the metacat* directory where the test lives and 
197
  &lt;test_name&gt; is the name of the JUnit test class. These output files will have
198
  all standard error and standard out output as well as information on assertion 
199
  failures in the event of a failed test.
200
  </p>
201
  
202
  <a name="TestDbVersions"></a><div class="header1">Testing Different Database Schema Versions</div>
203
  <p>Now and again it is necessary to restore your test database to an older schema version
204
  either because you need to test upgrade functionality, or you need to test backwords 
205
  compatibility of code.  This section describes how to get your db schema to an older 
206
  version.
207
  
208
  <a name="Scripts"></a><div class="header2">Scripts to Run</div>
209
  <p>It is assumed that you have an empty metacat database up and running with a 
210
  metacat user.
211
  <p>There are two types of scripts that need to be run in order to create a Metacat
212
  schema:</p>
213
  <ul>
214
  <li>xmltables-&lt;dbtype&gt;.sql - where &lt;dbtype&gt; is either oracle or postgres
215
  depending on what type of database you are running against.  This script creates the
216
  necessary tables for Metacat.</li>
217
  <li>loaddtdschema-&lt;dbtype&gt;.sql - where &lt;dbtype&gt; is either oracle or postgres
218
  depending on what type of database you are running against.  This script creates the
219
  necessary seed data for Metacat.</li>
220
  </ul> 
221
  
222
  <a name="CheckoutScripts"></a><div class="header2">Get Scripts Via Checkout</div>
223
  <p>One way to get the scripts you need is to check out the release tag for the version
224
  of metacat that you want to install.  You can then run the two scripts shown above to
225
  create your database.</p>
226
  
227
  <a name="ScriptRepo"></a><div class="header2">Script Repository</div>
228
  <p>For convenience, the scripts to create each version have been extracted and 
229
  checked into:</p>
230
    <div class="code">&lt;metacat_code&gt;/src/scripts/metacat-db-versions</div>
231
  <p>The files look like:</p>
232
  <ul>
233
  <li>&lt;version&gt;_xmltables-&lt;dbtype&gt;.sql - where &lt;version&gt; is the version
234
  of the schema that you want to create and &lt;dbtype&gt; is either oracle or postgres
235
  depending on what type of database you are running against.  This script creates the
236
  necessary tables for Metacat.</li>
237
  <li>&lt;version&gt;_loaddtdschema-&lt;dbtype&gt;.sql - where &lt;version&gt; is the version
238
  of the schema that you want to create and &lt;dbtype&gt; is either oracle or postgres
239
  depending on what type of database you are running against.  This script creates the
240
  necessary seed data for Metacat.</li>
241
  <li>&lt;version&gt;_cleanall-&lt;dbtype&gt;.sql - where &lt;version&gt; is the version
242
  of the schema that you want to create and &lt;dbtype&gt; is either oracle or postgres
243
  depending on what type of database you are running against. This is a convenience script
244
  to clean out the changes for that version.</li>

  <a name="TestingRegistry"></a><div class="header2">Testing Metadata Registry</div>   
363
  <p>The following skins use a perl based registry service to register metadata and
364
     data in metacat via the web: </p>
365
     <div class="code">nceas, esa, ltss, obfs, nrs, sanparks, saeon</div>
366
  <p>Following the instructions in the <a href="#TestingSkins"> Testing Skins</a> section
367
     go to each of these skins and test:</p>
368
     
369
  <ul>
370
  <li>Choose the "Register Dataset" link</li>
371
  <li>Fill out required fields.  Note that there are typically many different fields.  
372
      You should test out different combinations including attaching datasets if
373
      available.</li>
374
  <li>Hit the "Submit Dataset" button</li>
375
  <li>Review the information for accuracy</li>
376
  <li>Submit the data set</li>

  <a name="TestingEcogridRegistry"></a><div class="header2">Testing the EcoGrid Registry Service</div>  
382
  <p>The EcoGrid registry service maintains a database of systems that are available to EcoGrid. Primarily, 
383
  these are Metacat instances which are built with the EcoGrid service automatically activated.  Testing
384
  the registry service is somewhat complicated.  The procedure described here uses Eclipse to test. 
385
  These instructions assume that you have Eclipse installed and the Seek project set up as a Java project
386
  in Eclipse.</p>
387
  
388
  <ul>
389
  <li>Configure the Seek project in Eclipse
390
    <ul>
391
    <li>Right click on the Seek project and go to Properties->Java Build Path->Source</li>
392
    <li>Only the following two direcories should be set up as source:
393
      <ul>
394
      <li>seek/projects/ecogrid/src</li>
395
      <li>seek/projects/ecogrid/tests</li>
396
      </ul>
397
    </li>
398
    <li>Right click on the Seek project and go to Properties->Java Build Path->Libraries</li>
399
    <li>Add all Jars from:
400
      <ul>
401
      <li>seek/projects/ecogrid/lib/</li>
402
      <li>seek/projects/ecogrid/lib/axis-1_3/</li>
403
      <li>seek/projects/ecogrid/build/lib/</li>
404
      </ul>
405
    </li>  
406
    <li>If you do not already have an Ant view open in Eclipse, in the menu, go to 
407
        Window->Show View->Ant</li>
408
    <li>drag the file from the seek project at seek/projects/ecogrid/build.xml into
409
        the Ant window you just opened.</li>
410
    <li>Double click the serverjar and stubjar targets to build those jar files.<li>
411
    <li>Right click on the Seek project and go to Properties->Java Build Path->Libraries</li>
412
    <li>Add the two Jar files you just created:
413
      <ul>
414
      <li>seek/projects/ecogrid/lib/RegistryServiceImpl.jar</li> 
415
      <li>seek/projects/ecogrid/lib/RegistryService-stub.jar</li>   
416
      </ul> 
417
    </li>  
418
    </ul>
419
  </li>
420
  <li>View the RegistryServiceClient usage
421
    <ul>
422
    <li>In Eclipse, go to the registry service client at: <br>
423
        seek/projects/ecogrid/src/org/ecoinformatics/ecogrid/client/RegistryServiceClient.java</li>
424
    <li>Right click on RegistryServiceClient.java and go to Run As->Open Run Dialog</li>
425
    <li>Name it something like "RegistryServiceClient noargs" since you are running it without arguments.</li>
426
    <li>Hit the "Apply" button and then the "Run" button.</li>
427
    <li>Proceed past the project error warning dialog</li>
428
    <li>In the Eclipse console you should see usage instructions that look like:
429
      <ul>
430
      <li>Usage: java RegistryServiceClient add session_id local_file GSH</li>
431
      <li>Usage: java RegistryServiceClient update session_id  docid local_file GSH</li>
432
      <li>Usage: java RegistryServiceClient remove session_id docid GSH</li>
433
      <li>Usage: java RegistryServiceClient list session_id GSH</li>
434
      <li>Usage: java RegistryServiceClient query session_id query_field query_string GSH</li>
435
      </ul>
436
    </li>
437
    <li>Note: now you can run the client using the green "run" button in the Eclipse
438
    menu. We will use that button from now on, instead of going to the java file.</li>
439
    </ul>    
440
  </li> 
441
  <li>List Registry Services on dev
442
    <ul>
443
    <li>In Eclipse, go to the green run button dropdown and choose "Open Run Dialog"</li>
444
    <li>Right click on the "RegistryServiceClient noargs" configuration you created earlier and choose "duplicate".</li>   
445
    <li>Name your new configuration "RegistryServiceClient list dev.nceas"
446
    <li>Go to the Arguments tab and enter: list 12345 http://dev.nceas.ucsb.edu/registry/services/RegistryService
447
      <ul>
448
      <li>This conforms to the list usage we saw earlier</li>
449
      <li>Note that the session ID is not needed for listing, so we include a random value.</li>
450
      <li>GSH always refers to the server where the registry database is held.</li>
451
      </ul>
452
    </li>
453
    <li>Choose "Run"</li>
454
    <li>Proceed past the project error warning dialog</li>
455
    <li>You should see a listing of details for all services registered on the dev server.</li>
456
    </ul>
457
  </li> 
458
  <li>Register a new  service on dev
459
    <ul>
460
    <li>Look in your service list you just printed and find a service that has a 
461
        service type of: http://ecoinformatics.org/identifierservice-1.0.0</li>
462
    <li>Get the service ID and use it to get the xml description from dev metacat by going to:</br>
463
        http://kepler-dev.nceas.ucsb.edu/kepler/metacat/&lt;service_id&gt;</li>
464
    <li>Save the file to disk</li>
465
    <li>Edit the file and change the id to something unique and the description to be something
466
        easily recognizable.</li>
467
    <li>In the browser, go to: http://kepler-dev.nceas.ucsb.edu/kepler/style/skins/dev/login.html</li>
468
    <li>Log in and make note of the sessionId that was returned</li>
469
    <li>In Eclipse, go to the green run button dropdown and choose "Open Run Dialog"</li>
470
    <li>Right click on the "RegistryServiceClient noargs" configuration you created earlier and choose "duplicate".</li>   
471
    <li>Name your new configuration "RegistryServiceClient add-test dev.nceas"
472
    <li>Go to the Arguments tab and enter: add &lt;sessionId&gt; &lt;xml_file_path&gt; http://dev.nceas.ucsb.edu/registry/services/RegistryService
473
      <ul>
474
      <li>This conforms to the add usage we saw earlier</li>
475
      <li>The &lt;sessionId&gt; is the id you got after loggin in via the dev skin.</li>
476
      <li>The &lt;xml_file_path&gt; is the full path to the descriptor file you downloaded and modified.</li>
477
      <li>GSH always refers to the server where the registry database is held.</li>
478
      </ul>
479
    </li>
480
    <li>Choose "Run"</li>
481
    <li>Proceed past the project error warning dialog</li>
482
    <li>You should see a message saying: "The new id is &lt;id&gt;, where &lt;id&gt; is the unique id
483
        you added to the service descriptor file.</li>
484
    <li>Follow the instructions shown above to list services to make sure your new service shows up</li>
485
    </ul>  
486
