| <p>This page describes how to add or modify Trafodion tests and/or test suites. Please refer to the <a href="contribute.html">Contribute</a> page for information about other ways to contribute to the Trafodion project.</p> |
| <p><b>Note</b>: The <a href="testing.html">Test</a> page describes how the different Trafodion test libraries are organized and how you run different test. You should familiarize yourself with that page before modifying the Trafodion tests.</p> |
| <div class="page-header"> |
| <h1 id="sql_tests">SQL Tests</h1> |
| </div> |
| <p>The SQL tests are located in: <b><tt>core/sql/regress</tt></b>. Please refer to the <a href="testing.html">Test</a> page for information about each directory. Below, each of these directories is referred to as <b><tt>$scriptdir</tt></b>.</p> |
| <p>The default output from <b><tt>core/sql/regress/tools/runallsb</tt></b> is located in <b><tt>$MY_SQROOT/rundir</tt></b>. This directory is referred to as <b><tt>$rundir</tt></b> below.</p> |
| <p>Files associated with individual tests use the following naming convention: <b><tt>\<Type\>\<number\></tt></b>. The files are organized as follows:</p> |
| <table border="0" class="bodyTable table table-striped table-hover"> |
| <thead> |
| <tr class="a"> |
| <th>Type </th> |
| <th>Usage </th> |
| <th>Location</th> |
| </tr> |
| </thead> |
| <tbody> |
| <tr class="b"> |
| <td>TEST </td> |
| <td>The test itself. </td> |
| <td><b><tt>$scriptdir/<test suite></tt></b></td> |
| </tr> |
| <tr class="a"> |
| <td>EXPECTED </td> |
| <td>The expected output from the test. </td> |
| <td><b><tt>$scriptdir/<test suite></tt></b></td> |
| </tr> |
| <tr class="b"> |
| <td>FILTER </td> |
| <td>Filters out variable results (for example, timestamps) from test results to ensure consistent runs. </td> |
| <td><b><tt>$scriptdir/<test suite></tt></b></td> |
| </tr> |
| <tr class="a"> |
| <td>LOG </td> |
| <td>The output from running the test. </td> |

| <div class="section"> |
| <h2 id="Modify_a_Test">Modify a Test</h2> |
| <p>The comments in a test provides information of what it does. Make your changes and then do the following:</p> |
| <ul> |
| <li>Run the test.</li> |
| <li>Verify that the LOG output is as desired.</li> |
| <li>Copy the LOG output to EXPECTED.</li> |
| <li>Rerun the test and verify that the test passes.</li> |
| </ul> |
| <div class="section"> |
| <h3 id="Output_with_Variable_Data">Output with Variable Data</h3> |
| <p>If there are time stamps or generated names that may vary from run to run or from user to user, then you need to create a <tt>FILTER\<test number\></tt> file. This will filter out the variable portions of the test results so the test results are consistent.</p> |
| <p>Example filter file: <b><tt>core/sql/regress/core/FILTER024</tt></b> </p> |
| <p><b><tt>core/sql/regress/tools</tt></b> contains generic filter files. These cover general/common variables in test output. You will need to add a new test specific filer if it’s specific to your new test output only. </p> |
| </div> |
| <div class="section"> |
| <h3 id="Check_In_Changes">Check In Changes</h3> |
| <p>Check in the TEST and EXPECTED files in <b><tt>$scriptsdir</tt></b>.</p> |
| </div> |
| </div> |
| <div class="section"> |
| <h2 id="Create_New_Test">Create New Test</h2> |
| <p>Creating a test is just a variation of <a href="#Modify_a_Test">Modify a Test</a>. The test should be associated with a test suite that covers the component you want to test. Please contact the <a href="mail-lists.html">Trafodion Developer List</a> if you need help chosing the correct test suite.</p> |
| <p>Once you’ve chosen the test suite and, therefore, the test source directory, you do the following:</p> |
| <ul> |
| <li>Add the new test file to the test file in the selected test-suite directory. |
| <ul> |
| <li>Use the naming convention found in the directory. (Normally: <b><tt>TEST\<nnn\></tt></b>)</li> |
| <li>Refer to <b><tt>core/sql/regress/runregr_\<test suite\>.ksh</tt></b> to verify the naming convention used.</li> |
| </ul></li> |
| <li>The test DDL should use the schema name associated with the test suite. |
| <ul> |
| <li>Refer to other test suites for examples.</li> |
| </ul></li> |
| <li>Test and validate as described in <a href="#Modify_a_Test">Modify a Test</a> above.</li> |
| </ul> |
| </div> |
| <div class="section"> |
| <h2 id="Create_New_Test_Suite">Create New Test Suite</h2> |
| <p>The test suites cover different SQL components. Most components should be covered with the existing test suites.</p> |
| <p>Do the following to create a new test suite:</p> |
| <ul> |
| <li>Create a new directory with the suite name under <b><tt>core/sql/regress</tt></b>; for example: <b><tt>\<new test suite\></tt></b>.</li> |
| <li>Refer to <a href="#Create_New_Test">Create New Test</a> for instructions on how to add tests to the new test suite.</li> |
| <li>Add a test driver in <b><tt>core/sql/regress/tools</tt></b> directory with name <b><tt>runregr_\<new test suite\>.ksh</tt></b>. (Just copy and modify one of the other test drivers.)</li> |
| <li>Add the new test suite to <b><tt>core/sql/regress/runallsb/TEST_SUBDIRS</tt></b>.</li> |
| </ul> |

| <blockquote><a href="http://trafodion.apache.org/">Apache Trafodion</a> is a webscale SQL-on-Hadoop solution enabling transactional or operational |
| workloads on Hadoop. <br /><br />The name "Trafodion" (the Welsh word for transactions, pronounced |
| "Tra-vod-eee-on") was chosen specifically to emphasize the differentiation that |
| Trafodion provides in closing a critical gap in the Hadoop ecosystem.<br /><br /> |
| Trafodion builds on the scalability, elasticity, and flexibility of Hadoop. Trafodion extends |
| Hadoop to provide guaranteed transactional integrity, enabling new kinds of big data |
| applications to run on Hadoop.</blockquote> |
