* This set of tests is related to issues raised in https://github.com/mybatis/mybatis-dynamic-sql/issues/100 and
29+
* https://github.com/mybatis/mybatis-dynamic-sql/issues/102.
30+
*
31+
* The basic idea is that we want to enable the user to call the build() method from any object along the
32+
* DSL chain and have predictable results.
33+
*
34+
* So this set of test cases tests calling the build() method at various points along the chain.
