| <div class="page-header"> |
| <h1 id="component_tests">Component Tests</h1> |
| </div> |
| <p>Trafodion comes with several component-specific testing libraries.</p> |
| <div class="section"> |
| <h2 id="SQL_Core">SQL Core</h2> |
| <p>The SQL core components are written in a combination of C++ and Java. </p> |
| <p>You should ensure that the current set of regression tests pass each time you add or modify a SQL feature.</p> |
| <p>If adding a new feature, then check that it is either covered by an existing regression test or add a new test to an existing test suite.</p> |

| <h3 id="Check_Test_Results">Check Test Results</h3> |
| <p>On completion, the test run prints out a test summary. All tests should pass, or pass with known diffs.</p> |
| <p>Test results are written to the <b><tt>runregr-sb.log</tt></b> file in each component’s directory. Therefore, you can check the test results after the fact as follows:</p> |
| <div class="source"> |
| <div class="source"> |
| <pre>cd $MY_SQROOT/rundir |
| grep FAIL */runregr-sb.log |
| </pre> |
| </div> |
| </div> |
| <p>A successful test run shows no failures.</p> |
| </div> |
| <div class="section"> |
| <h3 id="Run_Full_Test_Suite">Run Full Test Suite</h3> |
| <p>This suite tests:</p> |
| <ul> |
| <li>SQL Compiler</li> |
| <li>SQL Executor</li> |
| <li>Transactions</li> |
| <li>Foundation</li> |
| </ul> |
| <p>Do the following:</p> |
| <div class="source"> |
| <div class="source"> |
| <pre>cd $MY_SQHOME |
| . ./sqenv.sh |
| cd $MY_SQROOT/../sql/regress |
| tools/runallsb |
| </pre> |
| </div> |
| </div> |
| </div> |
| <div class="section"> |
| <h3 id="Run_Individual_Test_Suites">Run Individual Test Suites</h3> |
| <p>You can select individual test suites as follows:</p> |
| <div class="source"> |
| <div class="source"> |
| <pre>cd $MY_SQHOME |
| . ./sqenv.sh |
| cd $MY_SQROOT/../sql/regress |

| </div> |

| <div class="section"> |
| <h3 id="Running_an_Individual_Test">Running an Individual Test</h3> |
| <div class="section"> |
| <h4 id="If_Youve_Already_Run_the_Test_Suite">If You’ve Already Run the Test Suite</h4> |
| <p>If you have already run the suite once, then you will have all your directories set up and you can run one test as follows:</p> |
| <div class="source"> |
| <div class="source"> |
| <pre>cd $MY_SQROOT/../sql/regress/<suite> |
| # You can add the following two exports to .bashrc or .profile for convenience |
| export rundir=$MY_SQROOT/rundir |
| export scriptsdir=$MY_SQROOT/../sql/regress |
| # run the test |
| cd $rundir/<suite> |
| $scriptsdir/<suite>/runregr -sb <test> |
| </pre> |
| </div> |
| </div> |
| <p><b>Example</b></p> |
| <div class="source"> |
| <div class="source"> |
| <pre>cd $rundir/executor |
| $scriptsdir/executor/runregr -sb TEST130 |
| </pre> |
| </div> |
| </div> |
| </div> |
| <div class="section"> |
| <h4 id="If_Youve_Not_Run_the_Test_Suite">If You’ve Not Run the Test Suite</h4> |
| <p>If you have not run any regression suites so far, then you will not have the required sub directories set up. You manually create them for each suite you want to run.</p> |
| <div class="source"> |
| <div class="source"> |
| <pre>cd $MY_SQROOT/../sql/regress/<suite> |
| # You can add the following two exports to .bashrc or .profile for convenience |
| export rundir=$MY_SQROOT/rundir |
| export scriptsdir=$MY_SQROOT/../sql/regress |
| mkdir $rundir |
| cd $rundir |
| # <suitename> should match the name of each directory in $scriptsdir |
| mkdir <suitename> |
| # run the test |
| cd $rundir/<suite> |
| $scriptsdir/<suite>/runregr -sb <test> |
| </pre> |
| </div> |
| </div> |
| </div> |
| </div> |
| <div class="section"> |
| <h3 id="Detecting_Failures">Detecting Failures</h3> |
| <p>If you see failures in any of your tests, you want to try running that suite or test individually as detailed above.</p> |
| <p>Open up the DIFF file and correlate them to the LOG and EXPECTED files.</p> |
| <ul> |
| <li>DIFF files are in <b><tt>$rundir/<suite name></tt></b>.</li> |
| <li>LOG files are in <b><tt>$rundir/<suite name></tt></b>.</li> |
| <li>EXPECTED files are in <b><tt>$scriptsdir/<suite name></tt></b>.</li> |
| </ul> |
| <p>To narrow down the failure, open up the test file (for example: <b><tt>TEST130</tt></b>) in <b><tt>$scriptsdir/executor</tt></b>. </p> |
| <p>Recreate the problem with a smaller set of SQL commands and create a script to run from <b><tt>sqlci</tt></b>. If it’s an issue that can be recreated only by running the whole suite, you can add a line to the test just before the command that fails to include a <b><tt>wait</tt></b> or a <b><tt>sleep</tt></b> <b><tt>sh sleep 60</tt></b> will make the test pause and give you time to attach the <b><tt>sqlci</tt></b> process to the debugger. (You can find the PID of the <b><tt>sqlci</tt></b> process using <b><tt>sqps</tt></b> on the command line)</p> |
| <p>Introducing a <b><tt>wait</tt></b> in the test will wait forever until you enter a character. This is another way to make the test pause to attach the debugger to the <b><tt>sqlci</tt></b> process. </p> |

| <p>If you would like to add coverage for your new change, you can modify an existing test.</p> |
| <p>Run the test after your modifications. If you are satisfied with your results, you need to modify the <b><tt>EXPECTED<test number></tt></b> file to reflect your new change. The standard way to do it is to copy the <b><tt>LOG<test number></tt></b> file to <b><tt>EXPECTED<test number></tt></b> file.</p> |

| <p>The Phoenix tests provides basic functional tests for Trafodion. These tests were originally adapted from their counterpart at salesforce.com.</p> |
| <p>The tests are executed using Maven with a Python wrapper. You can run them the same way on your own workstation instance just like the way Jenkins runs them. Do the following:</p> |
| <!-- This part is done in raw HTML because it's too complex to do this level of formatting in markdown. --> |
| <ol style="list-style-type: decimal"> |
| <li>Prior to running Phoenix tests, you need to bring up your Trafodion instance and DCS. You need to configure at least 2-4 servers for DCS. The tests need at least two mxosrvrs as they make two connections at any given time. We recommend configuring DCS with four mxosrvrs since we have seen situations that mxosrvrs do not get released in time for the next connection if there are only two mxosrvrs.</li> |
| <li> <p>Run the Phoenix tests from source tree</p> <p style="text-indent=20px"> </p> |

| <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> |
