Testing
|

~~~~~~~
|
||||
|

| s3select contains several testing frameworks which provide a large coverage for its functionalities.
|

|
||||
| (1) tests comparison against trusted engine, meaning, C/C++ compiler is a trusted expression evaluator,
|
||||
| since the syntax for arithmetical and logical expressions are identical (s3select compare to C)
|
||||
| the framework runs equal expressions and validates their results.
|
||||
| A dedicated expression generator produces different sets of expressions per each new test session.
|
||||
|
||||
| (2) compare results of queries whose syntax is different but semantically they are equal.
|
||||
| this kind of test validates that different runtime flows produce identical result,
|
||||
| on each run with different dataset(random).
|
||||
|
||||
| For one example, on a dataset which contains a random numbers(1-1000)
|
||||
| the following queries will produce identical results.
|
||||
| ``select count(*) from s3object where char_length(_3)=3;``
|
||||
| ``select count(*) from s3object where cast(_3 as int)>99 and cast(_3 as int)<1000;``
|
||||
|
||||
| (3) constant dataset, the conventional way of testing. A query is processing a constant dataset, its result is validated against constant results.
