/**
+ * Runner of SQL Unit tests. Needs an implementation of {@link ISqlScriptExecutor} to do the actual tests.
+ * The runner executes all test scripts found in the specified test scripts folder. The folder should have the
+ * following structure
+ * <pre>
+ * <<i>test script folder</i>>
+ * <<i>1. test case</i>>
+ * buildup.sql
+ * 1=<<i>first test</i>>.sql
+ * 2=<<i>second test</i>>.sql
+ * ...
+ * teardown.sql
+ * <<i>2. test case</i>>
+ * ...
+ * ...
+ * </pre>
+ * The test cases are executed in lexicographical order of their name. For each test case <code>buildup.sql</code>
+ * will be executed first. The test scripts follow the naming schema
+ * <pre>
+ * <<i>decimal number</i>>=<<i>test name</i>>.sql
+ * </pre>
+ * They are executed in ascending order of their numbers. Finally <code>teardown.sql</code> is executed.
+ * If execution of <code>buildup.sql</code> failed all test scripts and the tear down script are skipped.
+ * Note that <code>buildup.sql</code> and <code>teardown.sql</code> are optional.
+ * <p>
+ * A script fails if its execution throws an exception. Its innermost cause (usually a {@link SQLException}) will
+ * be recorded together with the name of the test case and the script. All failed scripts will be recorded.
+ * <p>
+ * The runner throws an {@link AssertionError} if at least one script failed.
