|
<p>Metacat uses JUnit tests to test its core functionality. These tests are
|
|
61
|
good for testing the internal workings of an application, but don't test the
|
|
62
|
layout and appearance. JUnit tests are meant to be one tool in the developer's
|
|
63
|
test arsinal. If you are not familiar with JUnit, you should search out some
|
|
64
|
tutorial documentation online. One such tutorial is at
|
|
65
|
<a href="http://clarkware.com/articles/JUnitPrimer.html"> The Clarkware JUnit primer</a></p>
|
|
66
|
|
|
67
|
<p>Metacat test cases will need to be run on the same server as the Metacat
|
|
68
|
instance that you want to test. Since Metacat and its test cases share the same
|
|
69
|
configuration files, there is no way to run the tests remotely.</p>
|
|
70
|
|
|
71
|
<a name="MetacatImplementation"></a><div class="header2">JUnit Implementation in Metacat</div>
|
|
72
|
<p>Metacat test cases are located in the code at:
|
|
73
|
<div class="code"><workspace>/metacat/test/edu/ucsb/nceas/metacat*/</div>
|
|
74
|
There you will find several java files that define JUnit tests.</p>
|
|
75
|
|
|
76
|
<p> Test cases are run via an ant task, and output from the tests appears in
|
|
77
|
a build directory. More on this to follow.</p>
|
|

|
<a name="WritingTestCase"></a><div class="header1">Writing a Test Case</div>
|
|
80
|
<a name="Basics"></a><div class="header2">Basics</div>
|
|
81
|
<p>All you need to do to get your JUnit test included into the Metacat test
|
|
82
|
suite is to create it in one of the <workspace>/test/edu/ucsb/nceas/metacat*/
|
|
83
|
directories. The ant test tasks will know that it should be run. </p>
|
|
84
|
|
|
85
|
<p> The following methods are required in a test case class:
|
|
86
|
<ul>
|
|
87
|
<li>public <Constructor>(String name) - The constructor for the test class. </li>
|
|
88
|
<li>public void setUp() - Set up any dependencies for the tests. This is run before each test case.</li>
|
|
89
|
<li>public void tearDown() - Release an resources used by the test.</li>
|
|
90
|
<li>public static Test suite() - define the test methods that need to be run.</li>
|
|
91
|
<li>public void initialize() - define any global initializations that need to be done.</li>
|
|
92
|
</ul>
|
|
93
|
|
|
94
|
You will test for failure using the many assertion methods available.</p>
|
|
95
|
|
|
96
|
<a name="MCTestCase"></a><div class="header2">MCTestCase Base Class</div>
|
|
97
|
<p>Metacat test cases extend the MCTestCase base class, which holds common
|
|
98
|
methods and variables. Some of these include:
|
|
99
|
<ul>
|
|
100
|
<li>SUCCESS/FALURE - boolean variables holding the values for success and failure. </li>
|
|
101
|
<li>metacatUrl, username, password - connection variables used for LDAP connectivity</li>
|
|
102
|
<li>readDocumentIdWhichEqualsDoc() - method to read a document from Metacat server.</li>
|
|
103
|
<li>debug() - method to display debug output to standard error.</li>
|
|
104
|
</ul>
|
|
105
|
These are just a few examples to give you an idea of what is in MCTestCase.
|
|
106
|
</p>
|
|
107
|
|
|
108
|
<a name="BestPractices"></a><div class="header2">Best Practices</div>
|
|
109
|
<p>The following are a few best practices when writing test cases:
|
|
110
|
<ul>
|
|
111
|
<li>Extend MCTestCase - Although strictly speaking, it is possible to bypass MCTestCase
|
|
112
|
and just extend the JUnit TestCase class, you should not do so. You should always
|
|
113
|
extend the MCTestCase class.</li>
|
|
114
|
<li>Extend Multiple Test Methods - Try to strike a balance between the number of test
|
|
115
|
methods and the size of each test. If a test method starts to get huge, you might see
|
|
116
|
if you can break it down into mulitple tests based on functionality. If the number of
|
|
117
|
tests in the test suite starts to get large, you might see if it makes sense to
|
|
118
|
separate them out into different test classes.</li>
|
|
119
|
<li>Use assertion message - Most assertion methods have an alternate implementation that
|
|
120
|
includes a message parameter. This message will be shown if the assertion fails. You
|
|
121
|
should use this version of the assertion method.</li>
|
|
122
|
<li>debug() - You should use the debug() method available in the MCTestCase class to
|
|
123
|
display debug output as opposed to System.err.println(). The test configuration will
|
|
124
|
allow you to turn off debug output when you use the debug() method.</li>
|
|
125
|
</ul>

|
|
128
|
<a name="AntTask"></a><div class="header2">Ant task</div>
|
|
129
|
<p>As we discussed earlier, the test cases run from within ant tasks. There is a
|
|
130
|
task to run all tests and a task to run individual tests. </p>
|
|
131
|
<p>You will need to have ant installed on your system. For downloads and instructions,
|
|
132
|
visit the <a href="http://ant.apache.org/">Apache Ant site</a>.
|
|
133
|
</p>
|
|
134
|
<a name="ConfigureMetacat"></a><div class="header2">Configure Metacat For Testing</div>
|
|
135
|
<p>The test cases will look at the server's metacat properties file for configuration,
|
|
136
|
so there are two places that need to be configured.</p>
|
|
137
|
<p>First, you need to edit the configuration file at:
|
|
138
|
<div class="code"><workspace>/metacat/test/test.properties</div>
|
|
139
|
This should only hold one property: metacat.contextDir. This should point to
|
|
140
|
the context directory for the metacat server you are testing. For example:
|
|
141
|
<div class="code">metacat.contextDir=/usr/share/tomcat5.5/webapps/knb</div>
|
|
142
|
The test classes will use this to determine where to look for the server
|
|
143
|
metacat.properties file.</p>
|
|
144
|
|
|
145
|
<p>the remainder of the configuration needs to happen in the actual server's
|
|
146
|
metacat.properties file located at:
|
|
147
|
<div class="code"><workspace>/metacat/lib/metacat.properties</div>
|
|
148
|
You will need to verify that all test.* properties are set correctly:
|
|
149
|
<ul>
|
|
150
|
<li>test.printdebug - true if you want debug output, false otherwise </li>
|
|
151
|
<li>test.metacatUrl - the url for the metacat servlet (i.e. http://localhost:8080/knb/metacat)</li>
|
|
152
|
<li>test.contextUrl - the url for the metacat web service (i.e. http://localhost:8080/knb)</li>
|
|
153
|
<li>test.metacatDeployDir - the directory where metacat is physically deployed (i.e. /usr/local/tomcat/webapps/knb)</li>
|
|
154
|
<li>test.mcUser - the first metacat test user ("uid=kepler,o=unaffiliated,dc=ecoinformatics,dc=org" should be fine)</li>
|
|
155
|
<li>test.mcPassword - the first metacat test password ("kepler" should be fine)</li>
|
|
156
|
<li>test.mcAnotherUser - the second metacat test user. This user must be a member of the knb-usr
|
|
157
|
group in ldap. ("uid=test,o=NCEAS,dc=ecoinformatics,dc=org" should be fine)</li>
|
|
158
|
<li>test.mcAnotherPassword - the second metacat test password ("test" should be fine)</li>
|
|
159
|
<li>test.piscoUser - the pisco test user ("uid=piscotest,o=PISCO,dc=ecoinformatics,dc=org" should be fine)</li>
|
|
160
|
<li>test.piscoPassword - the pisco test password ("testPW" should be fine)</li>
|
|
161
|
<li>test.lterUser - the lter test user ("uid=tmonkey,o=LTER,dc=ecoinformatics,dc=org" should be fine)</li>
|
|
162
|
<li>test.lterPassword - the lter test password ("T3$tusr" should be fine)</li>
|
|
163
|
<li>test.testProperty - a property to verify that we can read properties (leave as "testing")</li>
|
|
164
|
</ul>
|
|
165
|
</p>
|
|
166
|
|
|
167
|
<p>Note that none of the test users should also be administrative users. This will mess up
|
|
168
|
the access tests since some document modifications will succeed when we expect them to fail.</p>
|
|
169
|
|
|
170
|
<p>Once this is done, you will need to rebuild and redeploy the Metacat server. Note that
|
|
171
|
changing these properties does nothing to change the way the Metacat server runs. Rebuilding
|
|
172
|
and redeploying merely makes the test properties available to the JUnit tests.</p>
|
|
173
|
|
|
174
|
<a name="RunAllTests"></a><div class="header2">Run All Tests</div>
|
|
175
|
<p>To run all tests, go to the <workspace>/metacat directory and type</p>
|
|
176
|
<div class="code">ant clean test</div>
|
|
177
|
You will see a line to standard output summarizing each test result.
|
|
178
|
</p>

|
|
|
180
|
<a name="RunOneTest"></a><div class="header2">Run One Test</div>
|

<p>To run one test, go to the <workspace>/metacat directory and type</p>
|
|
182
|
<div class="code">ant clean runonetest -Dtesttorun=<test_name></div>
|
|
183
|
Where <test_name> is the name of the JUnit test class (without .java on
|
|
184
|
the end). You will see debug information print to standard error.
|
|
185
|

|
|
187
|
<a name="ViewingOutput"></a><div class="header2">Viewing Test Output</div>
|

188
|
<p>Regardless of whether you ran one test or all tests, you will see output in
|
|
189
|
the Metacat build directory in your code at:
|
|
190
|
<div class="code"><workspace>/metacat/build</div>
|
|
191
|
There will be one output file for each test class. The files will look like
|
|
192
|
<div class="code">TEST-edu.ucsb.nceas.<test_dir>.<test_name>.txt</div>
|
|
193
|
where <test_dir> is the metacat* directory where the test lives and
|
|
194
|
<test_name> is the name of the JUnit test class. These output files will have
|
|
195
|
all standard error and standard out output as well as information on assertion
|
|
196
|
failures in the event of a failed test.

<a name="TestDbVersions"></a><div class="header1">Testing Different Database Schema Versions</div>
|

200
|
<p>Now and again it is necessary to restore your test database to an older schema version
|
|
201
|
either because you need to test upgrade functionality, or you need to test backwords
|
|
202
|
compatibility of code. This section describes how to get your db schema to an older
|
|
203
|
version.

205
|
<a name="Scripts"></a><div class="header2">Scripts to Run</div>
|
|
206
|
<p>It is assumed that you have an empty metacat database up and running with a
|
|
207
|
metacat user.
|
|
208
|
<p>There are two types of scripts that need to be run in order to create a Metacat
|
|
209
|
schema:</p>
|
|
210
|
<ul>
|
|
211
|
<li>xmltables-<dbtype>.sql - where <dbtype> is either oracle or postgres
|
|
212
|
depending on what type of database you are running against. This script creates the
|
|
213
|
necessary tables for Metacat.</li>
|
|
214
|
<li>loaddtdschema-<dbtype>.sql - where <dbtype> is either oracle or postgres
|
|
215
|
depending on what type of database you are running against. This script creates the
|
|
216
|
necessary seed data for Metacat.</li>
|
|
217
|
</ul>
|
|
218
|
|
|
219
|
<a name="CheckoutScripts"></a><div class="header2">Get Scripts Via Checkout</div>
|
|
220
|
<p>One way to get the scripts you need is to check out the release tag for the version
|
|
221
|
of metacat that you want to install. You can then run the two scripts shown above to
|
|
222
|
create your database.</p>
|
|
223
|
|
|
224
|
<a name="ScriptRepo"></a><div class="header2">Script Repository</div>
|
|
225
|
<p>For convenience, the scripts to create each version have been extracted and
|
|
226
|
checked into:</p>
|
|
227
|
<div class="code"><metacat_code>/src/scripts/metacat-db-versions</div>
|
|
228
|
<p>The files look like:</p>
|
|
229
|
<ul>
|
|
230
|
<li><version>_xmltables-<dbtype>.sql - where <version> is the version
|
|
231
|
of the schema that you want to create and <dbtype> is either oracle or postgres
|
|
232
|
depending on what type of database you are running against. This script creates the
|
|
233
|
necessary tables for Metacat.</li>
|
|
234
|
<li><version>_loaddtdschema-<dbtype>.sql - where <version> is the version
|
|
235
|
of the schema that you want to create and <dbtype> is either oracle or postgres
|
|
236
|
depending on what type of database you are running against. This script creates the
|
|
237
|
necessary seed data for Metacat.</li>
|
|
238
|
<li><version>_cleanall-<dbtype>.sql - where <version> is the version
|
|
239
|
of the schema that you want to create and <dbtype> is either oracle or postgres
|
|
240
|
depending on what type of database you are running against. This is a convenience script
|
|
241
|
to clean out the changes for that version.</li>
